A freshly installed CentOS or RHEL runs many daemons which you don’t really want on a server, especially on a VPS where memory and CPU are usually more valuable resources.
Here’s what I usually do on a fresh server (tested with CentOS 5.x):
# stop unneeded services chkconfig gpm off chkconfig yum-updatesd off chkconfig xfs off chkconfig autofs off chkconfig portmap off chkconfig nfslock off chkconfig rpcidmapd off chkconfig hidd off chkconfig bluetooth off chkconfig netfs off chkconfig pcscd off chkconfig cups off chkconfig smartd off chkconfig avahi-daemon off chkconfig hplip off chkconfig messagebus off chkconfig iscsi off chkconfig iscsid off # disable graphical login screen vi /etc/inittab id:3:initdefault: # disable SE Linux if necessary vi /etc/selinux/config SELINUX=disabled reboot
