The Perfect Server - CentOS 6.4 x86_64 (Apache2, Dovecot, ISPConfig 3)
This tutorial shows how to prepare a CentOS 6.4 x86_64 server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, Mailman, and many more. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache; this tutorial covers the setup of a server that uses Apache, not nginx.
Installing Lighttpd With PHP5 (PHP-FPM) And MySQL Support On Scientific Linux 6.3
Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a Scientific Linux 6.3 server with PHP5 support (through PHP-FPM) and MySQL support. PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. I use PHP-FPM in this tutorial instead of Lighttpd's spawn-fcgi.
How To Use Multiple PHP Versions (PHP-FPM & FastCGI) With ISPConfig 3 (CentOS 6.3)
Since ISPConfig 3.0.5, it is possible to use multiple PHP versions on one server and select the optimal PHP version for a website. This feature works with PHP-FPM (starting with PHP 5.3) and FastCGI (all PHP 5.x versions). This tutorial shows how to build PHP 5.3 and PHP 5.4 as a PHP-FPM and a FastCGI version on a CentOS 6.3 server. These PHP versions can be used together with the default PHP (installed through yum) in ISPConfig.
Set Up Squid Siblings On CentOS 6.3 With WCCP
This tutorial will walk you through setting up a couple of outbound Squid proxy sibling servers running on CentOS 6.3 and have them connected to your gateway using WCCP. This will not cover the tuning of Squid in terms of cache performance.
Serving CGI Scripts With Nginx On Fedora 18
This tutorial shows how you can serve CGI scripts (Perl scripts) with nginx on Fedora 18. While nginx itself does not serve CGI, there are several ways to work around this. I will outline two solutions: the first is to proxy requests for CGI scripts to Thttpd, a small web server that has CGI support, while the second solution uses a CGI wrapper to serve CGI scripts.
Using mod_spdy With Apache2 On CentOS 6.3
SPDY (pronounced "SPeeDY") is a new networking protocol whose goal is to speed up the web. It is Google's alternative to the HTTP protocol and a candidate for HTTP/2.0. SPDY augments HTTP with several speed-related features such as stream multiplexing and header compression. To use SPDY, you need a web server and a browser (like Google Chrome and upcoming versions of Firefox) that both support SPDY. mod_spdy is an open-source Apache module that adds support for the SPDY protocol to the Apache HTTPD server. This tutorial explains how to use mod_spdy with Apache2 on CentOS 6.3.
How To Use Multiple PHP Versions (PHP-FPM & FastCGI) With ISPConfig 3 (Ubuntu 12.04 LTS)
Since ISPConfig 3.0.5, it is possible to use multiple PHP versions on one server and select the optimal PHP version for a website. This feature works with PHP-FPM (starting with PHP 5.3) and FastCGI (all PHP 5.x versions). This tutorial shows how to build PHP 5.3 and PHP 5.4 as a PHP-FPM and a FastCGI version on an Ubuntu 12.04 server. These PHP versions can be used together with the default PHP (installed through apt) in ISPConfig.
Building PHP 5.4 From Source On Debian Squeeze
This tutorial describes how you can build PHP 5.4 from source on Debian Squeeze. Later on, we will install more modules through PECL and add it as an additional PHP version to ISPConfig's dropdown. At the end you will have a fully function PHP 5.4 installation which is selectable within the ISPConfig interface and a .deb package than can be used on other server as well.
Virtualization With KVM On A Scientific Linux 6.3 Server
This guide explains how you can install and use KVM for creating and running virtual machines on a Scientific Linux 6.3 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.
How To Do Mass Enrolling Of Yubikey With LinOTP
When it comes to two factor authentication Yubikeys are very in vogue. They are small, they have a very small footprint on your keychain and are easy to handle as they need no driver and authentication is as easy as touching a button. This howto shows, how you can use the open source LinOTP to enroll many Yubikeys to the LinOTP server.
