  • How to setup Wordpress High Availability

    - by Ketam
    I have installed Galera Cluster on 3 cluster + 1 management. I wanted to make it like this, Server1: Home (www.domain.com) Server2: For BBpress/Forum (Forum Tab Menu will forward to forum.domain.com) Server3: BuddyPress Activity (Social Tab Menu will forward to social.domain.com) The purpose I am doing this is to distribute my resource and load balancing each other at same time. However, I have difficulty to setup Apache Load-Balancing/mod_proxy/clustering or any suitable to have high availability WordPress. Any best suggestion/solution to make high availability WordPress? Or how to? And another question is I tried to copy whole WordPress files & folders to Server2 connecting to local database (same data inside since it is already on Galera Cluster) but the page blank. Any advice? OS: Centos 6.2 Thanks in advanced.

  • nginx conditional Accept header

    - by manu_v
    Some mobile devices send the following incorrect requests to our servers : GET / HTTP/1.0 Accept: User-Agent : xxx The empty Accept header causes our Ruby on Rails server to throw back a 500 error. In Apache, the following directive allows us to rewrite the header before sending it to the application RoR server in order to cope with the broken devices : RequestHeader edit Accept ^$ "*/*" early We're currently setting up nginx, but achieving the same work-around is proving difficult. We are able to set : proxy_set_header Accept */*; However, this seems to have to be done inconditionally. Whenever trying to do : if ($http_accept !~ ".") { proxy_set_header Accept */*; } It complains with the message : "proxy_set_header" directive is not allowed here So, using nginx, how can we set the HTTP Accept header to */* when it is empty before sending the request to the application server ?

  • SharePoint MOSS - Serve HTTP content on an HTTPS page without Mixed Content Warning?

    - by kcb263
    Our "portal-like" SharePoint site is served using HTTPS/SSL. So a user goes to https://web.company.com and sees content and different Web Parts. So far, no problem. The desire now is to have new Web Parts added that either frame HTTP content (such as Weather Bug) or HTTP RSS feeds. The issue that arises is that by doing this, results in a "Mixed Content" warning in the browser. Has anybody successfully been able to implement such a scenario, or one similar to it? The options we have looked at, unsuccessfully, have been: using Apache Reverse Proxy Server mirror an external site Custom Web Parts

  • I installed DKIM and SPF. Do I need to install Domain Keys as well?

    - by johnlai2004
    I have linux apache mysql and php server. My website uses the php mail() function and the server's postfix server to email other people. I successfully installed SPF and DKIM on my server to reduce the likelihood of my website's email-outs from ending up in people's spam boxes. In my research, I stumbled on Domain Keys which seems to be a "historical" version of DKIM. Do the big web mail services like Google, Yahoo and Hotmail still use Domain Keys? If not, then maybe I don't need to install it?

  • Hourly CRON task running more frequently than one hour

    - by Justin
    I have a cron task that calls a special PHP script via wget. Here is the crontab entry: 0 * * * * wget http://www.... It will work perfect for several days, running on the hour. However, after a few days the cron job will start to be called several times an hour. I have never seen CRON drift like this, so I imagine it can't really be a CRON issue. However, the logs of the script that is called clearly show it running several times an hour. Server details: Ubuntu Luci Apache MySQL PHP5 Time is showing correct @ command line Server is setup to sync with a NTP server In order for the script to run it must be passed a unique 50-character hash key in the URL, so this script isn't being called from any other source accidentally. What might cause CRON to drift like this?

  • Minimalistic flatfile-based "wall" PHP app with authentication and RSS?

    - by Nicolas Raoul
    I am looking for an open-source minimalistic "message board" PHP software. Not a forum, more something like one simple facebook wall. The only thing a user can do is post a new message. With RSS, and able to run on flat files (no database) with Apache+PHP Authentication based on a configuration file, no management UI needed. For now I use this software, but it lacks RSS: http://nrw.free.fr/data/projects/pano/demo/index.php?pano=ifc Anyone knows a software that matches my description? Thanks! Usage: communication between my family's 5 members living on different continents.

  • Syntax for piping varnish logs to rotatelogs

    - by jetboy
    Ubuntu 12.04 Server x64, Varnish 3.0.2 I'm trying to pipe varnishncsa's logs through Apache's rotatelogs, and running from the shell, things work fine: sudo varnishncsa -a -P /var/run/varnishncsa/varnishncsa.pid |/usr/sbin/rotatelogs /var/log/varnish/varnish.log.%Y%m%d%H 3600 creates a new logfile in /var/log/varnish, with rotation every hour (3600 seconds). However, I'm struggling to get things working the same way inside /etc/init.d/varnishncsa: PATH=/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/usr/bin/$NAME PIDFILE=/var/run/$NAME/$NAME.pid LOGFILE=/var/log/varnish/varnishncsa.log USER=varnishlog DAEMON_OPTS="-a -P ${PIDFILE}" DAEMON_PIPE="|/usr/sbin/rotatelogs /var/log/varnish/varnish.log.%Y%m%d%H 3600" ... start_varnishncsa() { output=$(/bin/tempfile -s.varnish) log_daemon_msg "Starting $DESC" "$NAME" create_pid_directory if start-stop-daemon --start --verbose --pidfile ${PIDFILE} \ --chuid $USER --exec ${DAEMON} -- ${DAEMON_OPTS} \ > ${output} 2>&1; then log_end_msg 0 else log_end_msg 1 cat $output exit 1 fi rm $output } Where should I put DAEMON_PIPE in the above code? I've tried at the end of: if start-stop-daemon --start --verbose --pidfile ${PIDFILE} which is where additional command line parameters usually go, but it isn't creating a logfile.

  • how to start with unmanaged vps?

    - by GaVrA
    Hello! I have a managed VPS, so whatever i need i can just ask my support, and they will do it for me. Now i plan to migrate to unmanaged VPS, so i need some guides, tips on how and where to start learning. I will have more specific questions once i start using it, but now i just need some general answers about this topic. Thanks. Update: Ok, i have decided to go for unmanaged VPS with cPanel. OS is CentOS-5. I contacted support only for some small(i think) things like creating new account in whm, some database importing, installing new software(rare)... What i will be using is apache, php, mysql. I think i will be able to cope with upgrading to new versions, so the thing that interests me the most is security i guess.

  • Would NetBSD be a good choice for a web server?

    - by Alexander
    I've the choice of crafting a NetBSD image for a Xen VPS host, and was just wanting to play around as I like BSD and wished to use it for my general web hosting. I will be hosting a low-mid traffic website and maybe a few other simple services. Do you think NetBSD would be a sufficient choice, in terms of general performance of multiple system users and fair amount of traffic to Apache compared to what Linux could normally handle? I am concerned if I do start to really like it and keep it, I may be limiting myself if I am to move further with my web host and get more traffic (and maybe a lot of FTP access and user shell accounts) Ken

  • How to stick my changes in httpd.conf on WHM/Cpanel/EasyApache

    - by Seiti
    I'm setting up a server and trying to configure the Apache. It only needs to work as a frontend to Tomcat. To do that I added some instructions to the VirtualHost directive, using mod_proxy: <VirtualHost *> ServerName myserver.domain.com ProxyRequests Off ProxyPass / http://myserver.domain.com:8080/ ProxyPassReverse / http://myserver.domain.com:8080/ </VirtualHost> It works fine, and if the need comes, I´ll use mod_jk. But, how do I do it the right way using easyapache, and stop it to always rewrite my changes.

    - by Abenil
    i have several subdomains(git.example.org, build.example.org, etc.), i have a router with an external ip and i have several virtual machines on a host computer with internal ips. Now i want to route git.example.org to internal ip 10.0.2.1 and build.example.org to internal ip 10.0.2.2. How can I do this?

  • Tomcat / Railo stop responding with no error output

    - by andrewdixon
    This is going to sound very vague and I'm sure it will be voted down for not giving enough information however I don't really have any to give as you will see. We have an AWS instance running Amazon Linux, Apache, Tomcat and Railo and from time to time the Tomcat/Railo simply stops responding to requests and there are no errors output in the catalina.out file or any of the other log files in the Tomcat logs directory. When I issue the command to restart Tomcat/Railo the restart scripts sits there for a while then says that Tomcat has not responded so it has killed it off and then it starts up again and everything is fine until it happens again, anything from a couple of minutes to a couple of days later. I have done my best to check other logs on the server but have found no messages at all to indicate why Tomcat/Railo has given up and stopped responding. Can anyone suggest any reason why it might be doing this and / or any other log file(s) that we could check to see what is happening. Thanks. Andrew.

  • SSL 3.0 warning in Chrome on Ubuntu 10.04LTS

    - by Leopd
    I'm running Apache2 with SSL on Ubuntu 10.04LTS. Chrome gives me this annoying warning when I inspect the certificate: The connection had to be retried using SSL 3.0. This typically means that the server is using very old software and may have other security issues. The relevant part of the apache config looks like: SSLEngine on SSLCertificateFile /etc/ssl/... SSLCertificateKeyFile /etc/ssl/... SSLCACertificateFile /etc/ssl/... SSLProtocol -all +SSLv3 +TLSv1 The last line I added to try to address this problem, but it's not working. Any advice on properly enabling TLS?

  • WAMP can connect to localhost but not 127.0.0.1

    - by Anagio
    I'm running WAMP which was working fine the other day. Today I tried connecting to 127.0.0.1 and my browser throws a 404. Both firefox and chrome. My hosts file is correct mapping 127.0.0.1 to localhost. I can telnet to both the IP and localhost port 80 and see a response from apache. When I go to localhost I see the WAMP landing page. I can go to localhost/folder and view the applications just fine. What can be causing the 404's when I go to 127.0.0.1?

  • starting Tomcat from Eclipse

    I've just got eclipse for jee installed, and also downloaded apache 6.0.29 and added it in eclipse preferences. I followed up this tutorial, and all i got when i run it is 404 page with "The requested resource (/WebService/) is not available." description. I can't even access root folder of tomcat at localhost:8080. However, if i start tomcat through concole command, it's working fine and home page and examples are accessible. I'm a complete noob at tomcat and eclipse(been working with netbeans before), so i've got no idea what's wrong.

  • Using a AWS EC2 Server to host a busy website and I need to set up a loadbalancing

    - by Philip Isaacs
    My company has one EC2 server running on AWS with a MYSQL-DB and Apache on the same instance. This one instance hosts a website built on PHP Zend Framework. The site runs like crap when it starts to get busy with a lot of traffic so I'm looking for some advice on how to set up something that can handle the load better. My first question is should I move the mysql DB on to a separate EC2 instance or perhaps use AWS's RDS service which looks like a nice option. I'm sort of new to some of this but I'm guessing I'll need at least two EC2 instances for serving the website from and some sort of load balancing mechanism to distribute traffic. But maybe not, I'm not sure. Also what are some best practices for how to replicate the data so that they stay in sync on both instances? Okay I know these are a lot of questions. But I don't know where to start so any advice will help.

  • I'd like to archive files from Ubuntu to Windows between two computers on a shared home network

    - by Wabbitseason
    I have an old laptop running Ubuntu 9.10 which I use as a LAMP environment for web development, and I have a comfortable, powerful desktop computer with Windows 7 installed on it. These two are connected to a home router so both can access the internet. I have been able to set up Samba so I can mount my Apache home directory so it is accessible from Windows and is mapped as a network drive. What I'd like to do is access some Windows folders from Linux so I could automatically create backups (with cron scripts) of my work to physically different locations on the Windows box. Perhaps at a later time I'd set up a local Subversion repository but I'd love to keep backups of that on the Windows drives too. Using Ubuntu's Places/Network menu I can see my desktop but I'm unable to log in to that despite having created the corrent username and password on Windows. All I can get is the following error message: "Unable to mount location. Failed to retrieve share list from server." What could be misconfigurated?

  • How to make a server check it's own availability on the web?

    - by Javawag
    Hi all, Just a quick question – my server is running at my house serving www pages at www.javawag.com. The problem is that my home internet connection keeps dropping randomly - for about 10 mins at a time. This is only an intermittent problem and will go away soon I hope. However, my server doesn't recover properly - when the connection comes back, I can still access it at 192.168.0.8 (locally) without any issue, but at www.javawag.com there's no reply! (Just an aside - my home internet connection is dynamic ISP, the domain www.javawag.com points to javawag.dyndns.org which in turn points to my IP, updated every minute by ddclient on the server) Is there some way for the server to check if it's accessible from the outside world periodically, and if not restart Apache/reboot? Oh, and if I reboot the problem fixes itself also! Javawag

  • Take Complete Image of CRM Server Application

    - by nicorellius
    I have heard of snapshots or ghost images like this. But I have never used this kind of tool to actually clone a piece of hard drive. I think Norton Partition Magic can do something like this as well, but haven't tried it. So my question is this: How can I duplicate a CRM server application exactly so that I can transfer it to another system? I have a CRM server running LAMP (Linux, Apache, MySQL, and PHP) and I urgently need to transfer these data to another system without actually installing, configuring the dependencies and then doing the same for the software itself. Has anyone done this or does anyone know how to do this?
