• Correct Path for Git Remote Add from Amazon EC2 Instance to OSX Client Machine

  - by filmnut

  I'm trying to do a git remote add from a repository that sits on a remote Amazon AMI back to a cloned copy of the SAME repository that is sitting on my local OSX machine. I'm confused about what file path to use. I assume it's something like: git remote add my_clone <OSX_User_Name>@<OSX_HOST_NAME>:<PATH_TO_CLONED_REPO> I obviously know what my <OSX_User_Name> is, and I can figure out my <PATH_TO_CLONED_REPO>, but I have no idea how to determine a <OSX_HOST_NAME> that would actually work. Can I just put in my external IP address, followed by my machine's internal IP address? (Note that I'm working behind a router.) Is ssh:// the correct protocol? Do I need to set up ssh access from the Amazon EC2 machine to the local OSX machine?

  I have such json: [ { "MOD_AXL": 0, "MOD_CDS_ID": 110000168, "MOD_CV": 0, "MOD_CV_CTM": null, "MOD_ID": 168, "MOD_MFA_ID": 514, "MOD_PC": 1, "MOD_PCON_END": 199007, "MOD_PCON_START": 196303, "MOD_PC_CTM": null, "Name": "2 CV"}, { "MOD_AXL": 0, "MOD_CDS_ID": 110004500, "MOD_CV": 0, "MOD_CV_CTM": null, "MOD_ID": 4500, "MOD_MFA_ID": 514, "MOD_PC": 1, "MOD_PCON_END": 198810, "MOD_PCON_START": 197808, "MOD_PC_CTM": null, "Name": "ACADIANE"}, { "MOD_AXL": 0, "MOD_CDS_ID": 110001660, "MOD_CV": 0, "MOD_CV_CTM": null, "MOD_ID": 1660, "MOD_MFA_ID": 514, "MOD_PC": 1, "MOD_PCON_END": 197712, "MOD_PCON_START": 196301, "MOD_PC_CTM": null, "Name": "AMI"} // etc..etc.. ]?

• Learn Cloud Computing – It’s Time

  - by Ben Griswold

  Last week, I gave an in-house presentation on cloud computing.  I walked through an overview of cloud computing – characteristics (on demand, elastic, fully managed by provider), why are we interested (virtualization, distributed computing, increased access to high-speed internet, weak economy), various types (public, private, virtual private cloud) and services models (IaaS, PaaS, SaaS.)  Though numerous providers have emerged in the cloud computing space, the presentation focused on Amazon, Google and Microsoft offerings and provided an overview of their platforms, costs, data tier technologies, management and security.  One of the biggest talking points was why developers should consider the cloud as part of their deployment strategy: You only have to pay for what you consume You will be well-positioned for one time event provisioning You will reap the benefits of automated growth and scalable technologies For the record: having deployed dozens of applications on various platforms over the years, pricing tends to be the biggest customer concern.  Yes, scalability is a customer consideration, too, but it comes in distant second.  Boy do I hope you’re still reading… You may be thinking, “Cloud computing is well and good and it sounds catchy, but should I bother?  After all, it’s just another technology bundle which I’m supposed to ramp up on because it’s the latest thing, right?”  Well, my clients used to be 100% reliant upon me to find adequate hosting for them.  Now I find they are often aware of cloud services and some come to me with the “possibility” that deploying to the cloud is the best solution for them.  It’s like the patient who walks into the doctor’s office with their diagnosis and treatment already in mind thanks to the handful of Internet searches they performed earlier that day.  You know what?  The customer may be correct about the cloud. It may be a perfect fit for their app.  But maybe not…  I don’t think there’s a need to learn about every technical thing under the sun, but if you are responsible for identifying hosting solutions for your customers, it is time to get up to speed on cloud computing and the various offerings (if you haven’t already.)  Here are a few references to get you going: DZone Refcardz #82 Getting Started with Cloud Computing by Daniel Rubio Wikipedia Cloud Computing – What is it? Amazon Machine Images (AMI) Google App Engine SDK Azure SDK EC2 Spot Pricing Google App Engine Team Blog Amazon EC2 Team Blog Microsoft Azure Team Blog Amazon EC2 – Cost Calculator Google App Engine – Cost and Billing Resources Microsoft Azure – Cost Calculator Larry Ellison has stated that cloud computing has been defined as "everything that we currently do" and that it will have no effect except to "change the wording on some of our ads" Oracle launches worldwide cloud-computing tour NoSQL Movement

• 10.10 freezing when sftp downloading

  - by aGr

  My ubuntu 10.10 is freezing during downloading from my other computer on sftp. I thought it might be some nautilus issues so I tried it via command line and I got the same thing - after few minutes the whole computer freezes. Mostly the numlock led is blinking (I've heard somewhere that this means a kernel panic), but not in 100% cases. I dunno if that helps but here is a log from /var/log/message in the time that this happened. At least I hope so - it wasn't that big, when it happened before. But this looks quite "errorish", right?

• Online Application Upgrade

  - by lsarecz

  Amikor HA (High Availability - Magas Rendelkezésre Állás) megoldásokról beszélünk, általában elsoként a klaszterek, redundáns megoldások jutnak eszünkbe. Pedig nem csak a hardver hibákra kell gondolni, hanem a tervezett leállásokkal is érdemes foglalkozni. Az egyik talán legkevésbé megoldott probléma az, ha egy alkalmazás verzió váltást kell végrehajtani úgy, hogy közben változik az adatstruktúra is. Ez nyilván azt eredményezi, hogy le kell állítani az adatbázist is, és az átszervezéseket, akár adat átalakításokkal együtt végre kell hajtani. De a legnagyobb probléma talán az, hogy amennyiben valami rosszul sül el, és vissza kell állni a kiinduló állapotra, akkor az adatbázis mentést is vissza kell tölteni, hiszen átmenetileg minden felhasználó aki épp használatba vette az új alkalmazás verziót már egy új adatstruktúrába kezdett dolgozni. Az Oracle Database Online Application Upgrade képessége, vagy pontosabb nevén az Edition Based Redefinition pontosan ezt a problémát célozza meg. Az Edition Based Redefinition 3 alap objektummal muködik, ezek: edition, editioning view és crossedition trigger. Az edition egy új nonschema objektum típus. 11gR2 verziótól minden adatbázis rendelkezik legalább egy edition-nel, melynek neve Ora$Base. Minden új edition egy már létezo gyermeke kell, hogy legyen. Amikor kapcsolódunk az adatbázishoz, meghatározható, hogy melyik edition-höz kapcsolódjunk. Kizárólag nézetek, szinonímák és PL/SQL ojektum típusoknak lehet több edíciója (ezek metadat típusú objektumok, nem tartalmaznak adatokat). Azok az objektumok, melyek több edícióval rendelkeznek egyedileg csak úgy azonosíthatók, ha az owner, name, namespace mellett az edition-t is megnevezzük. Azaz két vagy több példánya is létezhet egy adatbázison belül ugyanazzal az owner, name és namespace azonosítókkal rendelkezo objektumnak, amennyiben használjuk az edition-based redefinition-t. Egy új objektum típus, az editioning view is edicionálható. Mivel a fizikai tábla nem edicionálható (elkerülendo az adatok többszörös tárolását és teljesítmény gondokat), ezért az editioning view feladata egy adott tábla egyszeru leképezése egy nézet formájában, ami már több edition-ben is létezhet, és képes elfedni a tábla módosításait. Amennyiben a tábla módosítások olyan táblákat érintenek, amelyek tartalmát  az alkalmazás felhasználók módosítják, szükség van olyan triggerekre, amelyek az egyes editioning view-k között a módosításokat karbantartják. Ezek a crossedition triggerek. Természetesen ahhoz, hogy az online application upgrade muködjön, minden érintett tábla elé el kell készíteni az editioning nézetet és a megfelelo crossedition triggereket. Ezeket használva az alkalmazás két vagy több különbözo verzió képes ugyanazon adatbázison párhuzamosan futni, és ha megtörtént a verzióváltás, akkor még mindig egyszeru visszaállni a régi verzióra egészen addig, amíg a régi edition eldobásra nem kerül. További információk az Edition-Based Redefinition címu whitepaper-ben találhatók.

• HP DL160G6 bios update fails

  - by Bojo

  I tried to update the BIOS from my HP DL160G6's. Unfortunately the Windows update degraded my BIOS version from 243 to 237. But when I try to upgrade both servers to version the update fails. First I got a warning like: CMOS Layout difference between System ROM and ROM file has detected. AFU recommand (sic) adding /C commands of your original input commands. Press "A" to accept AFU's recommendation. Press "F" to keep original input commands. And the update did not do anything. But now I get a message like: Reading flash ........ done Bootblock checksum ... ok Module checksums ..... bad Error: BIOS checksum error And the update stops. I tried some commands form this page: http://www.ami.com/support/downloads/txt/AFU_README.TXT But I don't try to much, the servers are still booting. Does anyone know how to update my servers to BIOS version 245? I used this version http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3884344&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3Didx%253D%257CswItem%253DMTX_7bd12651ab954fdcb0d7ee164a%257CswEnvOID%253D54%257CitemLocale%253D%257CswLang%253D%257Cmode%253D%257Caction%253DdriverDocument&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken and created a bootable USB stick sith HPQUSB.exe

• Graphics card not working but integrated graphics is working

  - by Dustin Martin

  I have a PCIe Geforce 6600 that I've been using in my PC for a couple years now without problems. Recently though I've not been using the PC and had it unplugged. When I when to use it again I accidentally plugged in the monitor to the VGA port for the integrated graphics instead of the 6600 card VGA port and began using it again (I'm currently running Windows 7). I then realized that I had the monitor plugged in wrong and switched the monitor to the 6600 port. Unfortunately I cannot get it to work. When the monitor is plugged in to the 6600 port the monitor will not display anything; not when booting up or in Windows (so I don’t believe the problem is Windows related). I've even tried booting a live CD for Ubuntu to see if that will recognize the card but no luck. Somehow it seems I need to "turn off" the integrated graphics and instruct the PC to use the 6600 card but I'm at a loss for how to do that. I looked high and low in the BIOS for a setting to do this but cannot find anything at all. I have a MSI motherboard and AMI Bios. Any ideas?

• FFMPEG Install on EC2 - Amazon Linux

  - by Oliver Holmberg

  Hello Serverfault friends, I am about two days into attempting to install FFMPEG with dependencies on an AWS EC2 instance running the Amazon Linux AMI. I've installed FFMPEG on Ubuntu and Fedora systems with no problems in the past, and have read reportedly successful instructions on installing on Red Hat/Fedora. I have followed a number of tutorials and forum articles to do so, but have had no luck yet. As far as I can tell, the main problems are as followed: The amazon linux (Most similar to red-hat/centos) yum repositories don't have ffmpeg available. I have found instructions to update the repositories to include the required packages, but adding these repositories cause yum to fail in updating packages. (Also, I've read some cautionary tales about adding redhat/centos repositories to amazon linux that lead me to believe it may be a bad idea) (https://forums.aws.amazon.com/thread.jspa?messageID=229166) I have tried a more complicated method of downloading the source tarball, compiling, and installing, but this always fails due to missing dependencies and other errors. On to my question: Has anyone successfully installed FFMPEG on Amazon Linux? Is there a fundamental incompatibility? If anyone could share specific instructions on installing ffmpeg on amazon linux I would be greatly appreciative. Any other insights/experiences would also be appreciated. Thanks in advance, Oliver

• How can I make my PCI-E graphics card visible to Ubuntu when the motherboard has integrated graphics

  - by Norman Ramsey

  I have a Gigabyte GA-MA74GM-S2 motherboard with integrated graphics that shows up on lspci as an ATI Radeon 2100. I also bought a PCI-Express Nvidia graphics card so I could use the VDPAU feature on Linux (plays H.264 in hardware). The BIOS has three settings about which display to initialize first: Integrated graphics PCI graphics PCI-Express graphics (PEG) I set the BIOS on PEG, but I cannot get anything, not even a splash screen or POST messages, to emerge from the PCI-Express graphics card. (I'm using a DVI connector; the card also has an HDMI output.) I cannot get the kernel lspci to see the graphics card; the only VGA controller it acknowledges is the integrated one. Running dmidecode acknowledges the existence of an x16 PCI Express slot, and it says Current usage: Unknown There is an additional BIOS setting called "Internal Graphics Mode" which is normally set to "Auto" which means it is supposed to prefer a PCI Express VGA card. I set it to "Disabled" which now means I'm getting no output at all. I will soon be learning how to do a BIOS reset! Other information: The PCI-E card is a MSI N210-MD512H GeForce 210. This is a fanless card. Although there are no fans to see turning, the heat sink on the PCI-E card is definitely getting hot, so the card is getting some sort of power. It gets all its power from the PCI-E slot; there is no external power connector. The BIOS is an AMI Award BIOS. My question: how can I make the PCI Express graphics card visible to Ubuntu?

• pure-ftpd not listening on specified port

  - by Jason McLaren

  I installed the pure-ftpd package (version 1.0.35-1) on an Ubuntu 12.04 box (an EC2 instance based on the standard Ubuntu 12.04 AMI). The pure-ftpd daemon is running (verified with ps), though there is no PID file (expected one to be created by the /etc/init.d/pure-ftpd script). Here's the resulting command that gets run by the init.d script: /usr/sbin/pure-ftpd -l pam -O clf:/var/log/pure-ftpd/transfer.log -o -8 UTF-8 -u 1000 -E -B -g /var/run/pure-ftpd/pure-ftpd.pid Here's my real problem: the ftp server isn't actually listening on any port (checked with netstat and nmap). So I can't ftp to the server (either locally using localhost or remotely using the public IP address). I tried adding a Bind file to /etc/pure-ftpd/conf and restarting, but it didn't help. When I installed pure-ftpd, it replaced inetd with openbsd-inetd, but did not run it since there were no services enabled. So inetd is not listening on port 21 either. (Apparently Ubuntu has a no-inetd-by-default policy, according to https://lists.ubuntu.com/archives/ubuntu-users/2010-September/227905.html .) I want to run pure-ftpd by itself (not with inetd) anyways, since the /etc/init.d/pure-ftpd script requires no inetd if you use the UploadScript feature. I'm not familiar with how Ubuntu handles network services (and can't find any relevant docs besides generic man pages), so I'm probably missing something obvious. Nothing seems out of the ordinary with /etc/hosts.allow (empty) or hosts.deny (empty), and I didn't add any firewall rules (iptables -L shows that the firewall is in its initial state). I've checked the pure-ftpd docs; not sure what else to look at. Any help would be appreciated, thanks!

• AMIs in Amazon EC2

  - by Jack of Trades

  I really like the Amazon EC2 environment, and thought I'll spend a bit of time playing around with various types of public (Windows!) AMI servers. But testing has been a bit, well, questionable. Some of my findings: It's very difficult to know what exactly a specific public EC2 image is supposed to be doing. Many images come with little to no information. I can't seem to find the passwords to log onto various windows images. Why are they public if they can't be used!? Lots of images are based on S3, and not EBS backed. This is very annoying, as S3 takes a lot longer to do pretty much anything (stop, image etc.) I am only testing images here, so of-course I don't question the value of S3 for other attributes. The description of what an image does is almost useless and many times confusing. Have others come across these EC2 issues. Again, my interest was to just play around with public images for testing/experimentation/etc, and therefore these issues may not be too relevant for more normal EC2 deployment uses.

  I have multiple websites hosted on 1 single EC2 instance. 1 website "abc" were down for a few hours, sometimes threw database connection error and sometimes just took too long to respond. 1 website "def" were incredibly slow but still up and running the rest of the websites had the same symptoms has "abc" I can afford 15 min or less down time for "def". Should I then (in AWS console) reboot my instance or create an AMI image from my instance and launch it and associate my elastic IP to the new instance or "launch more like this" Background on what may have happened to my ec2 The last time I made changes for 21 hours ago. A cronjob to create snapshots ran around 19 hours ago and it has been running for a long time. Google Analytics shows traffic to my websites such as kidlander.sg has been nothing exceptional. Is there any other actions I should take or better options I could have? (I have already contacted AWS support but their turnaround is 12 hours so I appreciate all the help I could get) Update I got everything back up and running and CPU utilisation back to normal, around 30%. There is 1 difference between "def" and "abc" as well as my other websites "def"'s database is hosted on RDS "abc"'s database is hosted on an EC2 instance (different from my web server instance) configured by myself Nevertheless, I checked the EC2 instance I'm using as MySQL server yesterday and it was absolutely fine during the incident low CPU ultilisation I could log in using linux command line

• AWS Linux EC2: yum won't run with plugins

  - by Patrick

  Short Version: yum commands on my Amazon Linux EC2 AMI only work with --noplugins. Long Version: A couple of days ago, I ran yum update at the behest of the SSH Login MoTD telling me I had updates to install. About midway through the update (specifically while updating the kernel), the update abruptly ended (79 of 138 items completed). The website I host on EC2 got weird for a few minutes, but eventually seemed to stabilize back out (maybe EC2 restarted itself?), and I didn't have further issues (other than MySQL started running out of memory, but I think that's probably unrelated to this). Today, I went to install gcc-c++ (with yum install gcc-c++). When I did, I got the following message: Loaded plugins: priorities, security, update-motd, upgrade-helper Config error: Command "updateinfo" already defined and I get that for any command I can think to run using yum. However, If I throw in the --noplugins flag, then magically it seems to work. To be clear, when I installed a different package a week ago, it worked totally correctly, so the yum update is the only thing I can think of that changed. I could find nothing on Google with regard to "updateinfo" already defined (with and without quotes). I tried running yum update --noplugins which spit out a message telling me that I should have run yum-complete-transaction instead, but proceeded to try to update something on its own. When that completed, I tried yum-complete-transaction but that gave me a message about the transactions not lining up correctly, so it removed the old transaction (Probably since I should have completed the first transaction before trying to update again, if I had known). Based on the SF question "Linux EC2 Broken Yum", I've also tried yum clean all --noplugins (fails the same with plugins) which just gives me Cleaning repos: amzn-main amzn-updates rpmforge Cleaning up everything I also tried package-cleanup --problems Loaded plugins: priorities, update-motd, upgrade-helper No Problems Found and package-cleanup --dupes Gives a lot of dupes, so I pasted them here: http://pastebin.com/VVFQEkTT instead of inline. At this point, I'm not sure what else there even is to check.

• No discs found when trying to install Windows 8 with UEFI

  - by Sahas Katta

  I have a Vizio Notebook (CN15-A5). It came pre-installed with Windows 8 x64 and is taking advantage of UEFI out of the box. The BIOS (APTOS AMI) is in Secure Boot mode with the OS selected as "Windows 8". I removed the stock HDD that came with the machine and put my own SSD into it. I created a Windows 8 Pro x64 installation disc on a 4GB USB flash drive formated as FAT32 since its apparently required for UEFI. When I boot from the USB Win8 installation disc, I get suck when I reach the "Custom: Install Windows only" section. Normally you would see a list of available discs and their partitions, however my entire list is blank. If I head back to the BIOS and disable Secure Boot and set the OS to "Other OS" and attempt again, I am able to see the list of available discs in the system and can install a copy of Windows 8. Unfortunately, doing it in this method results in an installation with a traditional 350 MB partition + OS partition instead of 4 partitions which is normal for a UEFI setup. Has anyone run into this problem? I've tried loading defaults in the BIOS and attempting to install via every combination with no luck. Any help would be appreciated.

• No clue for high load average on top

  We have several machines on Amazon (ec2) of the type c1.xlarge with 16 cpus, running the Amazon AMI.

• No apparent reason for high load average

  - by Oz.

  We have several web servers running on Amazon (ec2) c1.xlarge, over Amazon AMI. The servers are duplicates of each other, running the exact same hardware and software. Each server spec is: 7 GB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High API name: c1.xlarge A couple of weeks ago we have run a yum upgrade on one of the servers. Starting on this upgrade the upgraded server started showing a high load average. Needless to say, we did not update the other servers and we can not do so until we understand the reason for this behavior. The strange thing is that when we compare the servers using top or iostat, we can not find the reason for the high load. Note that we have moved traffic from the "problematic" server to the others, which have made the "problematic" server less crowded in terms of requests, and still his load is higher. Do you have any idea what could it be, or where else can we check? Many thanks for the help!

• SFTP, Chroot problems on Redhat

  - by Curtis_w

  I'm having problems setting up sftp with a ChrootDirectory. I've done an equivalent setup on other distros, but for some reason I cannot get it to work on a Redhat AMI. The changes to my sshd_config file are: Subsystem sftp internal-sftp Match Group ftponly PasswordAuthentication yes X11Forwarding no ChrootDirectory %h ForceCommand internal-sftp AllowTcpForwarding no I have the concerned usere's homes at /home/user, owned by root. After connecting with a user in the ftponly group, I'm dropped into / without permissions for anything, and am unable to do anything. sftp bob@localhost Connecting to localhost... bob@localhost's password: sftp> pwd Remote working directory: / I can connect normally with users not in the ftponly group. openssh version 5.3 I've experimented with different permissions, as well as having users own their own home directory (gives a Write failed: Broken pipe error), and so far, nothing has seemed to work. I'm sure it's a permissions error, or something equally as trivial, but at this point my eyes are beginning to glaze over, and any help would be greatly appreciated. EDIT: James and Madhatter, thanks for clarifying. I was confused by chroot dropping me in /... just didn't think through it properly. I've added the appropriate directories and permissions to get read access. One other key part was enabling write access to chrooted homes: setsebool -P ssh_chroot_rw_homedirs on in order to get write access. I think I'm all set now. Thanks for the help.

• SSH attack CentOS Amazon EC2

  - by user37143

  Hi, I run a few Rightscale CentOS AMI based instances on Amazon EC2. Two months back I found that our SSHD security is compromised( I had added host.allow and host.deny for ssh). So I created new instances and done an IP based ssh that allows only our IPs through AWS Firewall(ec2-authorize) and chnaged the ssh 22 default port to some other port but two days back I found I was not able to login to the server and when I tried on 22 port the ssh got connected and I found that sshd_conf was changed and when I tried to edit sshd_config I found root had no write permission on the file. So I tried a chmod and it said access denied for 'root' user. This is very strange. I checked secure log and history and found nothing informative. I have PHP, Ruby On Rails, Java, Wordpress apps running on these server. This time I did a chkrootkit scan and found nothing. I renamed the /etc/ssh folder and reinstalled openssh through yum. I had faced this on 3 instances on CentOS(5.2, 5.4) I have instances on Debian as well those working fine. Is this a CentOS/Rightscale issue. Guys, what security measures I should take to prevent this. Please support me this is very critical. Thanks

• Looking for suggestions for hosting Windows 2000 Server in the cloud / VPS / etc?

  - by JohnyD

  I have a Windows 2000 Server, currently virtualized in Hyper-V, that I would like to get running off-site as a backup (cloud, VPS, etc). You can't virtualize in EC2 and I'm fairly certain there are no Server 2000 AMI's floating about (correct me if I'm wrong!). If anyone has a recommendation on how I can get a virtualized Windows 2000 Server running in a secure, remote environment I would be grateful. As far as locations go I'd be interested in both North America as well as Australia and Europe. In a nutshell, we're ploughing our way out of a legacy codebase and this server is the last that remains of the legacy apps. However, it is still very much used by our clients. Everything is backed up each night (data, images, etc) to tape which is then taken offsite. However, in the event of a fire I would love to have a backup legacy server to point DNS records to. So while I am rebuilding from the ashes our services would already be available. It would save a lot of time and make my managers all the more happy (and that's what it's all about, riighhtt? :D) Thank you all for your suggestions. Please let me know if I've left out any important information. Additional info: - the legacy codebase does not function properly in Server 2003

• MySQL Not Turning On

  - by Shalin Shah

  I have an amazon ec2 instance running on the Amazon Linux AMI and its a micro instance. I wanted to install Django onto my server so I entered these commands wget http://www.mlsite.net/blog/wp-content/uploads/2008/11/go wget http://www.mlsite.net/blog/wp-content/uploads/2008/11/django.conf chmod 744 go ./go So after I was done, I ran sudo service httpd restart and sudo service mysqld restart and This is what came up for mysqld: Stopping mysqld: [ OK ] MySQL Daemon failed to start. Starting mysqld: [FAILED] So I deleted the django files /usr/local/python2.6.8/site-packages/django_registration.egg and I tried finding the error and I found out that in my /etc/my.cnf for the socket, it said socket=/var/lock/subsys/mysql.sock so I went to /var/lock/subsys/ and there was no mysql.sock. I tried creating one using vim but it still didn't work. Then I checked the error log and it said Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) So I am pretty much lost right now. I know it has something to do with mysql.sock If you might know a reason why this was caused could you please let me know? I have a wordpress site on my server, so i kind of need MySQL to work. Thanks!

• sysbench memory test on ec2 small instance

  - by caribio

  I'm seeing a problem with sysbench memory test (the default version that's compiled in). This is on Ubuntu Maverick, sysbench installed via apt-get install sysbench. Running the same thing on Ubuntu @ Rackspace worked just as expected. While the CPU and I/O tests worked fine on EC2 servers, the memory test just runs without doing anything (notice the 0M in the test results). The instance used was the publicly available 'stock' Ubuntu image with no changes to it: ./ec2-run-instances ami-ccf405a5 --instance-type m1.small --region us-east-1 --key mykey Supplying more arguments (such as: --memory-block-size=1K --memory-total-size=102400M) didn't help.

• AWS: Multi-region setup using single RDS instance

  - by Ion

  I'm trying to scale our web application (PHP, MySQL, memcache) in a multi-region scheme. Currently we are using a setup with two EC2 instances behind an ELB and an RDS instance, all of them in US-EAST (Virginia) region. We would like to have a presence in the EU (Ireland) region as well. This means at least a new EC2 instance there (identical to the others, serving the same application). I have copied the desired AMI, setup the new instance, setup a same ELB configuration (required for SSL termination) and configured latency-based routing in Route53. And it works as suggested. But, clients from EU have speed problems. This is due to the fact that the EU EC2 instances connect to the US-based RDS instance. As far as I know Amazon has not yet enabled RDS multi-region replication. Do you have any suggestions on how to properly speed up the whole setup while using the single RDS instance? Also, any ideas in general on how to scale things up? Ideally we would like to continue using the RDS technology for various reasons. Nevertheless, I am open to suggestions (I guess the next idea would be to host our own MySQL servers).
