Rackspace.com Cloud Server – Nginx v1.0.2, PHP-FPM 5.3.6, Xcache v1.3.1, MariaDB 5.2.6 Install

Revisiting CentOS 5.x 64bit install on Rackspace.com Cloud Server environment but this time for testing source installation of Nginx v1.0.2, PHP 5.3.6 (php-fpm) and Xcache v1.3.1 along with MariaDB 5.2.6 64bit RPM binaries.

Rackspace cloud server - Nginx v1.0.2, PHP 5.3.6 PHP-FPM installation

After installing it all manually, I came across a an awesome bash shell install script over at webhostingtalk.com called Centmin created by BTCental. This would reduce alot of the manual installation work involved!

Centmin is a bash script developed for use on CentOS 5.
It is designed to provide a fully functional NMP plus DNS stack – using minimal resources.

BTCentral Centmin features:
– Updates any pre-installed software (via Yum)
– Secures /tmp (and /var/tmp) directories
– Installs development tools needed for compilation of Nginx and NSD
– Sets server to use your local timezone
– Installs Nginx, MySQL, PHP 5.3.6 (with FPM)
– Installs NSD (DNS Server – a low-memory alternative to BIND)
– Installs NTP (Other than on OpenVZ VPS)
– Installs Sendmail (enables PHP to use the mail function)
– Optional: Installs Alternative PHP Cache

Current Version:
1.1.0 (Released 29/04/2011)
Be sure to follow us on Twitter to keep informed of the latest updates.

How to use:

1) Download the script from:
London, UK (via Linode): wget http://www.centmin.com/download.php
New York, US (via 6sync): wget http://www.centmin.com/download.php?m=ny
Los Angeles, US (via PhotonVPS): wget http://www.centmin.com/download.php?m=la

2) Extract the archive:
tar xzf centmin-latest.tar.gz

3) Follow the instructions in the included readme.txt

Released under the GNU GPLv3 licenseReadmeChange Log

So I modified the Centmin script with my own version of installation options and additional parameters. Then proceeded to do a few test installations on my local VirtualBox CentOS 5.6 based server. Update: I made a 2nd revision to add Memcached server support

Changes in my version:

  • Changed script to install MariaDB 5.2.6 MySQL 64bit instead of MySQL standard versions included with CentOS 5.5 – MySQL 5.0.77
  • Changed Nginx configure options with addition options and Google Perftool tcmalloc support
  • Changed PHP 5.3.6 php-fpm installation to compile from source with additional options
  • Both Nginx and PHP compiled with OpenSSL 1.0.0d support instead of OpenSSL 0.9.8e
  • Changed config/php-fpm/www.conf to config/php-fpm/php-fpm.conf with adjusted options
  • Added xcache v1.3.1 installation option
  • Added config/mysql/my.cnf tuned for MariaDB 5.2.6
  • Added config/xcache/xcache.ini settings for Xcache v1.3.1
  • Added config/nginx/fastcgi_params with buffer tuning
  • Added php support to default server in config/nginx/nginx.conf
  • Removed fastcgi_intercept_errors on; options in virtual.conf as already added to fastcgi_params include file
  • Added additional checks in php containers in virtual.conf

  1. Is this environment/installation of Nginx, php, etc what you use for large vb forums?

  2. Hi Phil

    No, personally I don’t use nginx for live vB forums. For high traffic large vB forums I use Litespeed web server or Litespeed web server + Litespeed cache or Litespeed web server + Varnish cache – see here http://vbtechsupport.com/33/ and here http://vbtechsupport.com/26/.

  3. Thanks that helps a lot.. I’m going to read up about the Litespeed w/cache for my forum of 600,000 threads as it seems to offer a speed boost over my current config.
