  • Apache to read from /home/user/public_html on CentOS 5.7

    - by C.S.Putra
    this is my first experience using CentOS 5.7 / Linux as my web server OS and I have just finished installing Apache. Then I created a new account using WHM. The account is now created and the domain name can be accessed. I have put the web files under /home/user/public_html/ but when I access the domain assigned for that user which I assigned when creating new account in WHM, it doesn't read the files. In /usr/local/apache/conf/httpd.conf : <VirtualHost 175.103.48.66:80> ServerName domain.com ServerAlias www.domain.com DocumentRoot /home/user/public_html ServerAdmin [email protected] User veevou # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup group1 group1 </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup group1 group1 </IfModule> CustomLog /usr/local/apache/domlogs/domain.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." CustomLog /usr/local/apache/domlogs/domain.com combined ScriptAlias /cgi-bin/ /home/user/public_html/cgi-bin/ </VirtualHost> Instead of reading from /home/user/public_html/ apache will read the /var/ww/html/ folder. How to set the apache so that when user access www.domain.com, they will access the files under /home/user/public_html/ ? Please advice. Thanks

  • Simple Workstation Imaging Solution?

    - by user23087
    I need a fairly cheap imaging solution for Windows XP corporate desktops. Ideally, I'd be able to set up a desktop exactly as we want it, create an image, deploy this image to a server, then boot a new desktop to a CD/USB Drive/Network and quickly set up the workstation. Ideally, each computer would also have a unique workstation name. Any ideas? Right now I'm using a custom built Linux DD solution, but it's slow, not network-based, can't image multiple computers at the same time as there's only one copy on a USB drive, and can't uniquely name the computers. Thanks, Will

  • Simple SQL Server 2005 Replication - "D-1" server used for heavy queries/reports

    - by Ricardo Pardini
    Hello. We have two SQL 2005 machines. One is used for production data, and the other is used for running queries/reports. Every night, the production machine dumps (backups) it's database to disk, and the other one restores it. This is called the D-1 process. I think there must be a more efficient way of doing this, since SQL 2005 has many forms of replication. Some requirements: 1) No need for instant replication, there can be (some) delay 2) All changes (including schemas, data, constraints, indexes) need to be replicated without manual intervention 3) It is used for a single database only 4) There is a third server available if needed 5) There is high bandwidth (gigabit ethernet) available between the servers 6) There isn't a shared storage (SAN) available What would be a good alternative to this daily backup/restore routine? Thanks!

  • Simple way to make wired internet wireless without router

    - by Anriëtte Combrink
    Hi there Is there any device which you can plug into an Ethernet port and then have it broadcast the internet connection it receives through Ethernet wirelessly with a set password (maybe a serial number on device itself)? The problem is, I have a Wi-fi capable device, an iPhone and I want to use the wired internet connection in a hotel room, but the iPhone needs a Wi-fi signal. How can I accomplish this with a rather simplistic device. // EDIT: Can this be achieved with an Apple Airport Express?

  • Simple end-to-end load and bottleneck monitoring for DB-based web sites

    - by T.J. Crowder
    What tools do you use / would you recommend for monitoring a Linux-based, DB-based website's servers for bottlenecks and load? The obvious goal being to know when growth has gotten to the point where it's necessary to scale up (or out) one or more of the bits and pieces because the current system won't be managing the load if an observed trend continues. I'm looking for general recommendations based on standard Linux load metrics, disk I/O metrics, network I/O metrics, etc., but if specifics are helpful: It'll be Tomcat6 using APR (possibly with a Varnish or similar caching and balancing front-end), MySQL, and either Ubuntu 8.04 LTS or 10.04 LTS depending on timing. I know about top, vmstat, iostat, bwmon and the like that collect and parse info from the /proc file system (et. al.); and obviously MySQL provides a lot of queriable performance information. I could use those directly, probably automating periodic monitoring logs with scripts and such. But I have a suspicion that I'd be reinventing a wheel... For example, Hyperic HQ seems to be along the lines of what I'm looking for. Others? Meta: I tend to think of "recommendation" questions as needing to be CW because there's no one right answer, but I see a lot of these here that aren't CWs, so I haven't marked it as one. I'll happily do so if enough people think I should.

  • Using GlusterFS for simple replication

    - by k7k0
    Hi, newbie question. I need to build this: /shared folder ~500GB of files, ~1MB each one. Two boxes (server1 and server2) connected by a 1Gbs LAN Every box needs to get r/w access to the files, so their are both clients I want that the files replicated on both boxes, every time a file is written in one server the same file should be present in the other one. My questions regarding GlusterFS: It'll duplicate the files on the same box?. For example the files are on /shared and the mount in /mnt/shared. It'll take 1GB space on every server? Instead, should I use the filesystem directly, locally writing on /shared? Does the replication work in this way without mountin a client? Also, if anyone know any other way to acomplish this setup I'll be very grateful. Thanks in advance.

  • MySQL as a simple Mac application for development

    - by Thilo
    What is the easiest way to run MySQL for development purposes on the Mac? Ideal would be a server embedded in a Mac application, that starts when you press a start button, and stops when you quit the app? I do not need a background service running, I do not want to have to be an admin user to install or run, I do not want files spread out all over the disk (everything should be in the App bundle and the Documents folder).

  • Simple Image Capture Tool for Mac OS X that uses FireWire

    - by Justin Dearing
    I have Leopard (Mac OS X 10.5) on a G4 Powerbook and a camcorder with a firewire device. It doesn't have iMovie, which is now part of the separate iLife Suite and requires an Intel Mac. Anyway, Image Capture does not recognize the firewire video feed as an image capture device. What software would give me the simplest "capture this frame from live firewire video feed to image" functionality.

  • Simple copy to pen-drive - 0x80070057

    - by yzraeu
    Hello guys, I have this problem for a while and still didn't find the answer. I'm copying a specifc 10mb file to my pen-drive, from any folder on PC to any folder on the pen-drive and all i get is this: 0x80070057 The parameter is incorrect I simply cannot copy the file at all!! The pen-drive in case is my Nokia 5800, in "Mass Storage" mode. Sometimes I cannot copy a single MP3 file, 5 or 7mb. So i have to disconnect and connect again. The source file is not corrupted, the destination works fine with other files. It's just with some files. If I change to another pen-drive, works fine.

  • How to setup a simple self-hosted dynamic DNS server

    - by Cerin
    I have a small internal network of physical machines running hypervisors, which in turn run several KVM Ubuntu virtual machines. How would I setup an internal dynamic DNS server so that when I run a script to create a new virtual machine, that VM could automatically register itself in the DNS server? Bind seems to be the standard DNS server for Linux, but it seems designed for a much more "static" DNS model. Dynamically updating this would require a complicated script that would have to SSH into the DNS server, edit configuration files, and then restart the server. This doesn't seem like a very elegant solution. Are there better options? I saw a similar question, although they're asking for a solution for a public setting on Amazon. My servers are entirely private, and I don't want to rely on an external VM host or Dynamic DNS provider.

  • Simple SSH public/private key question

    - by James R.
    I am trying to learn this instead of just following guides so I can recommend proper actions when people do ask (and they do). Here is what I got down. First, generate both key with command such as this: ssh-keygen -b 2048 -t rsa -C comment -f ~/.ssh/id_rsa Then you push the public part of the key into authorized_keys2 file cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys2 (and then chmod it to 600 or similar) And you download the private key to your computer (id_rsa) and feed that in to Putty to be read and authenticate. Are these the correct steps to setting this public/private key authentication for passwordless login to SSH?

  • simple and reliable centralized logging inside Amazon VPC

    - by Nakedible
    I need to set up centralized logging for a set of servers (10-20) in an Amazon VPC. The logging should be as to not lose any log messages in case any single server goes offline - or in the case that an entire availability zone goes offline. It should also tolerate packet loss and other normal network conditions without losing or duplicating messages. It should store the messages durably, at the minimum on two different EBS volumes in two availability zones, but S3 is a good place as well. It should also be realtime so that the messages arrive within seconds of their generation to two different availability zones. I also need to sync logfiles not generated via syslog, so a syslog-only centralized logging solution would not fulfill all the needs, although I guess that limitation could be worked around. I have already reviewed a few solutions, and I will list them here: Flume to Flume to S3: I could set up two logservers as Flume hosts which would store log messages either locally or in S3, and configure all the servers with Flume to send all messages to both servers, using the end-to-end reliability options. That way the loss of a single server shouldn't cause lost messages and all messages would arrive in two availability zones in realtime. However, there would need to be some way to join the logs of the two servers, deduplicating all the messages delivered to both. This could be done by adding a unique id on the sending side to each message and then write some manual deduplication runs on the logfiles. I haven't found an easy solution to the duplication problem. Logstash to Logstash to ElasticSearch: I could install Logstash on the servers and have them deliver to a central server via AMQP, with the durability options turned on. However, for this to work I would need to use some of the clustering capable AMQP implementations, or fan out the deliver just as in the Flume case. AMQP seems to be a yet another moving part with several implementations and no real guidance on what works best this sort of setup. And I'm not entirely convinced that I could get actual end-to-end durability from logstash to elasticsearch, assuming crashing servers in between. The fan-out solutions run in to the deduplication problem again. The best solution that would seem to handle all the cases, would be Beetle, which seems to provide high availability and deduplication via a redis store. However, I haven't seen any guidance on how to set this up with Logstash and Redis is one more moving part again for something that shouldn't be terribly difficult. Logstash to ElasticSearch: I could run Logstash on all the servers, have all the filtering and processing rules in the servers themselves and just have them log directly to a removet ElasticSearch server. I think this should bring me reliable logging and I can use the ElasticSearch clustering features to share the database transparently. However, I am not sure if the setup actually survives Logstash restarts and intermittent network problems without duplicating messages in a failover case or similar. But this approach sounds pretty promising. rsync: I could just rsync all the relevant log files to two different servers. The reliability aspect should be perfect here, as the files should be identical to the source files after a sync is done. However, doing an rsync several times per second doesn't sound fun. Also, I need the logs to be untamperable after they have been sent, so the rsyncs would need to be in append-only mode. And log rotations mess things up unless I'm careful. rsyslog with RELP: I could set up rsyslog to send messages to two remote hosts via RELP and have a local queue to store the messages. There is the deduplication problem again, and RELP itself might also duplicate some messages. However, this would only handle the things that log via syslog. None of these solutions seem terribly good, and they have many unknowns still, so I am asking for more information here from people who have set up centralized reliable logging as to what are the best tools to achieve that goal.

  • Replicated MongoDB server slower than simple shards

    - by displayName
    I tried to compare the performance of a sharded configuration against a sharded and replicated configuration. The sharded configuration consists of 8 shards each running on three different machines thereby constituting a total of 24 shards. All 8 of these shards run in the same partition on each machine. The sharded and replicated version is 8 shards again just like plain sharding, and all 8 mongods run on the same partition in each machine. But apart from this, each of these three machine now run additional 16 threads on another partition which serve as the secondary for the 8 mongods running on other machines. This is the way I prepared a sharded and replicated configuration with data chunks having replication factor of 3. Important point to note is that once the data has been loaded, it is not modified. So after primary and secondaries have synchronized then it doesn't matter which one i read from. To run the queries, I use an entirely different machine (let's call it config) which runs mongos and this machine's only purpose is to receive queries and run them on the cluster. Contrary to my expectations, plain sharding of 8 threads on each machine (total = 3 * 8 = 24) is performing better for queries than the sharded + replicated configuration. I have a script written to perform the query. So in order to time the scripts, I use time ./testScript and see the result. I tried changing the reading preference for replicated cluster by logging to mongo of config and run db.getMongo().setReadPref('secondary') and then exit the shell and run the queries like time ./testScript. The questions are: Where am i going wrong in the replication? Why is it slower than its plain sharding version? Does the db.getMongo().ReadPref('secondary') persist when i leave the shell and try to perform the query? All the four machines are running Linux and i have already increased the ulimit -n to 2048 from initial value of 1024 to allow more connections. The collections are properly distributed and all the mongods have equal number of chunks. Goes without saying that indices in both configurations are the same.

  • Simple active directory permissions issue

    - by Antonio2011a
    So I've created a domain controller (DC) as well as 3 machines (SQL-A, SQL-B, SQL-CORE). All are running Windows Server2008R2 (on virtualbox). I have successfully joined the 3 machines to the domain controller. Next I created a user in active directory called Kim_Akers who is a member of "Domain Admins", "Domain users", "Enterprise Admins" and "Schema Admins". However when I login to SQL-A for example as contso/Kim_Akers and then try and run something like the ServerManager.msc I can't do it due to lack of permissions "Windows cannot access the specified device, path or file. You may not have the appropriate permissions". What am I doing wrong that Kim_Akers doesn't have permissions to do this? Thanks.

  • Using Round Robin DNS on simple VPN setup

    - by dannymcc
    We have two internet connections which are load balanced to share the load between the two. We set this up after one of the internet provider proved to be less than reliable but great speed and latency wise when it is working. We'd rather utilise both connections as much as possible rather than leave one idle until the other drops out. We have a number of remote workers who occasionally need to connect via VPN from their laptops or iPads, we also have a small number of permanent LAN to LAN tunnels running from smaller branches. Originally we only had one internet connection and used one of our static IP addresses for all VPN users. Now that we have two internet connections running all of the time I am trying to make sure that the VPN is available to our team regardless of which connection drops. So my solution is to create two A records for our domain name with a value of vpn. and the two static IP addresses from each peer. Is this a sensible way of achieving this? Should I expect higher latency due to packets being lost if one peer fails and some packets still get routed to it anyway? A brief mockup of the setup I have:

  • Simple Webserver failover

    - by yummm
    I will be running a dynamic web site and if the server ever is to stop responding, I'd like to failover to a static website that displays a "We are down for maintenance" page. I have been reading and I found that switching the DNS dynamically may be an option, but how quick will that change take place? And will everyone see the change immediately? Are there any better ways to failover to another server?

  • simple apache2 reverse proxy setup not working

    - by Nick
    I know what proxy is (very high level), it's just I have never set up one, and it feels like I might be missing some big fat point here. My setup: client server (static IP), runs apache on port 80 proxy (has 2 network cards, one is on the clients network, the other one with a static IP on the server network), runs apache on port 80 I am trying to configure these three machines so that when client requests: http://proxy/machine1 It gets served server's pages at server root URL, i.e. http://server/ I can access client pages just fine. However, when I try accessing a page from the client machine, it simply gets redirected to server's IP address, which it clearly can't access since they are not on the same network: ... <meta http-equiv="REFRESH" content="0;url=http://server/machine1"></meta> <title>Redirect</title> ... My apache2 config is: LoadModule proxy_module /modules/mod_proxy.so LoadModule proxy_http_module /modules/mod_proxy_http.so ProxyRequests off <Proxy *> Order Allow,Deny Allow from all </Proxy> ProxyPass /machine1 http://server:80 <Location /machine1> ProxyPassReverse / </Location> What gives? Thanks!
