Centos5.8 _ 64-bit Operating System

Install desktops and virtual hosts, disable SELINUX, and disable firewall,

1. Memory and swap partition size. The server can be installed with 2 GB or more memory. The server space should be as large as possible.

Minimum: 1 GB of RAM

Recommended: 2 GB of RAM or more

Todetermine the RAM size, enter the following command:

# GrepMemTotal/proc/meminfo

Swap partition size settings

Between1 GB and 2 GB allocated 1.5 times the size of the RAM

Between2 GB and 16 GB allocated to the size of the RAM

Morethan 16 GB allocated 16 GB

# GrepSwapTotal/proc/meminfo determine the size
