  • What is the best way to change the replication scheme of 2 currently replicated slaves?

    - by mmattax
    I have MySQL replication set up in production as follows: DB1 - DB2 DB1 - BAK Where DB2 and BAK are slaves to DB1. All 3 servers are in sync (0 seconds behind the master) and have 30+ GB of data. I'd like to put the servers in a new master-slave configuration as follows: DB1 - DB2 - BAK What is the best way to change the master host on BAK? Is there a way to avoid having to stop the slave thread on DB2 and getting a mysqldump for BAK (a 5-6 hour processes) ?

  • How to setup loopbackon my Windows Server 2008 Virtual PC VM?

    - by user39846
    I am trying to setup a virtual sharepoint environment for development and need to be able to access my sharepoint sites on my host machine. From hours of google research, I discern that I must setup loopback, but haven't been able to get it to work and can't find a detailed guide. Can anyone please post a details on how to set this up?

  • Using more recent kernel for Xen Dom0 in production.

    - by thelsdj
    Does anyone have experience running Xen dom0 on a more recent kernel than the stock 2.6.18? What host distro are you running? What release of Xen (or hg/git changeset)? What set of patches are you using on kernel source? (Has anyone got the pvops dom0 stuff working in production or is it better to stick with something like the SUSE patches? Any other tips and tricks to running a more recent kernel version as dom0 would be helpful.

  • How do I create a bridged virtual network for libvirt+KVM+ubuntu-server the easy way?

    - by Arthur Ulfeldt
    I see lots of documentation on how to manually set up a network bridge and then manually add vm's tun devices to these bridges and then write a shell script that glues it all together. lots of work, very manual, and not impressive. On the other hand if you want to use NAT to KVM+libvirt VMs to the network you just click the new network button in the virt-manager gui and relax. Am I missing "the easy way" of causing a VM to share the physical network with the host?

  • How to disable or tune filesystem cache sharing for OpenVZ?

    - by gertvdijk
    For OpenVZ, an example of container-based virtualization, it seems that host and all guests are sharing the filesystem cache. This sounds paradoxical when talking about virtualization, but this is actually a feature of OpenVZ. It makes sense too. Because only one kernel is running, it's possible to benefit from sharing the same pages of filesystem cache in memory. And while it sounds beneficial, I think a set up here actually suffers in performance from it. Here's why I think why: my machines aren't actually sharing any files on disk so I can't benefit from this feature in OpenVZ. Several OpenVZ machines are running MySQL with MyISAM tables. MyISAM relies on the system's filesystem cache for caching of data files, unlike InnoDB's buffer pool. Also some virtual machines are known to do heavy and large I/O operations on the same filesystem in the host. For example, when running cat *.MYD > /dev/null on some large database in one machine, I saw the filesystem cache lowering in another, monitored by htop. This essentially flushes all the useful filesystem cache in guests (FIFO) and so it flushes the MySQL caches in the guests. Now users are complaining that MySQL is very slow. And it is. Some simple SELECT queries take several seconds on times disk I/O is heavily used by other machines. So, simply put: Is there a way to avoid filesystem cache being wiped out by other virtual machines in container-based virtualization? Some thoughts: Choosing algorithm for flushing filesystem cache in the kernel. (possible? how?) Reserving a certain amount of pages for a single VM. (seems no option for filesystem cache type of pages that reading man vzctl) Will running MySQL on another filesystem get me anywhere? If not, I think my alternatives are: Use KVM for MySQL-MyISAM running VMs. KVM actually assigns memory to the VM and does not allow swapping out caches unless using a balloon driver. Move to InnoDB and tune the buffer pools, dirty pages, etc. This is now considered to be 'nice to have' on the long-term as not everyone responsible for administration of the system understands InnoDB. more suggestions welcome. System software: Proxmox (now 1.9, could be upgraded to 2.x). One big LV assigned for the VMs.

  • How to Run vnc4server on Ubuntu in Certain Resolution?

    - by Boris Pavlovic
    There's a headless Ubuntu instance used as a host for our build server. I have some UI code that requires some graphical output. Installing a vnc4server and redirecting a DISPLAY to it worked like a charm. Not that my UI tests are running but test scripts can take screen shots. Problem is that I need to set the resolution that vnc4server uses to serve the graphical content. Does anybody know how to configure it on Ubuntu server?

  • DNS Issue Windows 2003 AD-The server holding the PDC role is down

    - by Dave M
    Our network of Windows 2003 and Windows 2008 servers suddenly hasDNS issues. There are 7 DCs. Two at our main office and one each at branch sites (one branch has two a 2008R2 and WIN2K3) Only two are WIN2008R2 Running DCDIAG on the WIN2K3 at main site (DC1) reports no issues. Running at any branch site reports two issues All other test pass. The server DC1 can be PINGed by name from any site Starting test: frsevent There are warning or error events within the last 24 hours after the SYSVOL has been shared. Failing SYSVOL replication problems may cause Group Policy problems. Starting test: FsmoCheck Warning: DcGetDcName(PDC_REQUIRED) call failed, error 1355 A Primary Domain Controller could not be located. The server holding the PDC role is down. Netdom.exe /query DC reports the expected servers. netdom query fsmo This reports the server at the main office holds the following roles: * Schema owner Domain role owner PDC role RID pool manager Infrastructure owner In the DNS management snap-in, DC1 appears as DNS server but does not appear in _msdcs-dc-_sites-Default-First-Site-Name-_TCP There is no _ldap or –kerberos record pointing to DC1 Same issue msdcs-dc-_sites- -_TCP Again there is no _ldap or –kerberos record pointing to DC1 Under Domain DNS Zones there is no entry for the server. This is the case for any _tcp folder in the DNS. The server DC1 appears correctly as a name server in the Reverse Lookup Zone. There is a Host(A) record for DC1 but in the Forward Lookup Zone there is no (same as parent folder) Host(A) for the DC1 server but such an entry exists for the other DCs at branch sites and the other DC at the main office. We have tried stopping and starting the netlogon service, restarting DNS and also dcdiag /fix.

  • Why isn't the backup file created when running sqlcmd from remote machine?

    - by Ed Gl
    I tried running the sqlcmd from a remote host to do a simple backup of a sql 2008 database. The command goes something like this: sqlcmd -s xxx.xxx.xxx.xx -U username -P some_password -Q "Backup database [db] to \ disk = 'c:\test_backup.bak' with format" I get a succesfull message but the file isn't created. When I run this on the sql manager on the same machine, it works. I thought it was permission problems, but I'm using the same username in both cases. Any thoughts?

  • How bad is it to use a virtual file system with VMWare?

    - by user37244
    IT is running a series of VMs that we'd like to see optimized further: if the VMs' are Windows XP, storing their NTFS images out to the virtual disk (ext3) provided by Linux/VMWare, how much of a hit are we taking - as opposed to having a partition of the host hard drive formatted NTFS to eliminate the translation layer and the extra level of operating system IO preparation?

  • Puppet and launchd services?

    - by Joel Westberg
    We have a production environment configured with Puppet, and want to be able to set up a similar environment on our development machines: a mix of Red Hats, Ubuntus and OSX. As might be expected, OSX is the odd man out here, and sadly, I'm having a lot of trouble with getting this to work. My first attempt was using macports, using the following declaration: package { 'rabbitmq-server': ensure => installed, provider => macports, } but this, sadly, generates the following error: Error: /Stage[main]/Rabbitmq/Package[rabbitmq-server]: Could not evaluate: Execution of '/opt/local/bin/port -q installed rabbitmq-server' returned 1: usage: cut -b list [-n] [file ...] cut -c list [file ...] cut -f list [-s] [-d delim] [file ...] while executing "exec dscl -q . -read /Users/$env(SUDO_USER) NFSHomeDirectory | cut -d ' ' -f 2" (procedure "mportinit" line 95) invoked from within "mportinit ui_options global_options global_variations" Next up, I figured I'd give homebrew a try. There is no package provider available by default, but puppet-homebrew seemed promising. Here, I got much farther, and actually managed to get the install to work. package { 'rabbitmq': ensure => installed, provider => brew, } file { "plist": path => "/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist", source => "/usr/local/opt/rabbitmq/homebrew.mxcl.rabbitmq.plist", ensure => present, owner => root, group => wheel, mode => 0644, } service { "homebrew.mxcl.rabbitmq": enable => true, ensure => running, provider => "launchd", require => [ File["/Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist"] ], } Here, I don't get any error. But RabbitMQ doesn't start either (as it does if I do a manual load with launchctl) [... snip ...] Debug: Executing '/bin/launchctl list' Debug: Executing '/usr/bin/plutil -convert xml1 -o /dev/stdout /Library/LaunchDaemons/homebrew.mxcl.rabbitmq.plist' Debug: Executing '/usr/bin/plutil -convert xml1 -o /dev/stdout /var/db/launchd.db/com.apple.launchd/overrides.plist' Debug: /Schedule[weekly]: Skipping device resources because running on a host Debug: /Schedule[puppet]: Skipping device resources because running on a host Debug: Finishing transaction 2248294820 Debug: Storing state Debug: Stored state in 0.01 seconds Finished catalog run in 25.90 seconds What am I doing wrong?

  • Postix transport smtp failover

    - by SimonJGreen
    We have a multi-tenant email relay set up that has a transport map file that looks like this: domain1.com smtp:mail.domain1.com domain2.com smtp:mail.domain2.com domain3.com smtp:mail.domain3.com [etc] In the event mail.domain1.com is down, email for domain1.com will be held by the postfix server until mail.domain1.com starts responding again. However we have a customer who has a backup DSL line on their site, an their email server is also available over this. How can I tell the transport to failover to a different host if the first is unavailable?

  • Choose relayhost based on the postfix smtpd instance

    - by Zizzencs
    I'd like to setup a postfix host (using RHEL 5.4's default postfix, which is version 2.3) with the following characteristics: an SMTP listener listens on 10.0.0.1:25 and relays all e-mails to 10.0.0.1:2525 an SMTP listener listens on 10.0.0.1:2525 and relays all e-mails to 10.0.0.2:25 Basically the challenge here is to use two different relayhosts for the different SMTP listeners. Is it possible? Is there a better solution to achieve similar behavior?

  • Restart a single apache vhost

    - by snowflake
    I've got an Apache (2) server with several virtual hosts. I currently have mysql db locks problems on one virtual host. A common and practical way to easy release those locks and unlock the site (while the dev team refactor its application to avoid the locks), is to simply restart the apache server. I'm wondering if there is a way to restart the single vhost that is in trouble. Thank you for any comments

  • Ubuntu stopped recognizing my iPod

    Rythmbox on Ubuntu 10.10 used to recognize my 3rd gen Nano and transfer mp3s. Now I plug it in and Ubuntu doesn't pop-up that box that asks what you want to do anymore.

  • Is it important to reboot Linux after a kernel update?

    - by lfaraone
    I have a few production Fedora and Debian webservers that host our sites as well as user shell accounts (used for git vcs work, some screen+irssi sessions, etc). Occasionally a new kernel update will come down the pipeline in yum/apt-get, and I was wondering if most of the fixes are severe enough to warrant a reboot, or if I can apply the fixes sans reboot. Our main development server currently has 213 days of uptime, and I wasn't sure if it was insecure to run such an older kernel.

  • How to process requests twice in Apache

    - by Pieter
    In order to perform realistic tests for a new backend server, I'd like to process all Apache requests twice. So simply handle all the live requests with the old server, as it's done right now, but then also 'duplicate' the requests to a different virtual host, where the new backend is deployed, which will process the request and log the response. What's the best / most simple way to achieve this in Apache? (the backend is a FastCGI process)

  • Port-forwarding HTTPS web server

    I have port forwarded our front-facing IP to an internal HTTPS server. The browser does not connect. A wget command determines that the certificate is self-signed for the internal IP. Hence why the browser is refusing to display the page properly. What is the best-practice scenario for this sort of stuff? Thanks

  • Benefits of setting a webserver in Linux

    - by John Kent
    I wonder what main purposes and benefits can one get after he sets up a webserver running on Linux installed on a VM which is hosted by Windows and that this webserver can be used as a local host for windows ? That is, I have java application that is a webserver made on Linux, I set up the virtual machine for the windows client apps to listen to its (Linux)'s local IP address and port e.g 192.168.50.50:11111 When my webserver runs, I can use http://192.168.50.50/ as the windows's localhost address (instead of 127.0.0.1 as I usually do). Thank you

    Hi all. I was wondering when connecting to a git repository, does the git+ssh protocol use the same port number as just using the git protocol. For example: git://example.com/git/helloworld git+ssh://[email protected]/git/helloworld I am trying to push to a remote repository that has port forwarding setup on only the git protocol port number (9418) using EGit. When I try and use the git+ssh, EGit tells me git+ssh://.... connection is closed by foreign host Thanks, Tomek
