Installing and Configuring Environment Modules on CentOS 6

This tutorial is very similar to Installing and Configuring Environment Modules on CentOS 5 and the steps are very similar for CentOS 6 except that the tcl/tk 8.5.x used in CentOS repository does not have tclConfig.sh which is needed when you compile the Modules packages. I used 8.4.x which is similar to the version used in the CentOS 5 repository. You can use more more updated version of tcl.

Installing and Configuring Environment Modules on CentOS 5

Here a short tutorial on how to install and configure Environmental Modules on CentOS. See
Installing and Configuring Environment Modules on CentOS 5 for more details.
In the short tutorial,  I have document steps how to

1. Tools of managing User Environment in Linux
2. Unpacking, Installing and Configure Environment Modules. The Environment Modules Package can be taken from Environment Modules Project
3. Creating a sample Module File for Intel Compilers

Tools of managing User Environment in Linux

As far as I know there are 2 tools used to manage the environment.

1. One tool is SoftEnv Manual

• Softenv is a system used to build the user's environment. Each user has a ".soft" file in which they specify groups of applications that they're interested in. Softenv reads a central database when necessary to update the user's PATH, MANPATH and other variables. This version of SoftEnv is currently being used at MCS. 
• Current version 1.6.2. The last time it was updated is 12 March 2007
• Download Site - Sotftenv

2. The other tool is Modules - Software Environment Management

• The Environment Modules package provides for the dynamic modification of a user's environment via modulefiles.
  
  Each modulefile contains the information needed to configure the shell for an application. Once the Modules package is initialized, the environment can be modified on a per-module basis using the module command which interprets modulefiles. Typically modulefiles instruct the module command to alter or set shell environment variables such as PATH, MANPATH, etc. modulefiles may be shared by many users on a system and users may have their own collection to supplement or replace the shared modulefiles. 
• Current Version modules-3.2.9c. The last update was 19th Nov 2011
• Download Site - Environment Modules
