One of the first steps that we should do while presetting a server is to disable unwanted services on the server. The server should be preloaded with some services like bluetooth, X services, etc which are not required to a server normally. The number of such services will vary, based on the default packages installed by your provider. After a little research, we have compiled in a list of services that can be disabled on  Linux servers. Please note that this is a generic one and you should check the list before implementing it, if you are going to build any custom stuff. Normally it should work seamlessly with control panel installations, web services , etc.

The list of services that can be disbaled are listed below seprately for VPS and dedicated servers.

You can use the following scripts to disable unneeded services for VPS and Dedicated servers respectively.

VPS
yum install wget ; cd /usr/local/src/ && wget http://nixtree.com/download/free/services_dis_vps.txt && for i in `cat services_dis_vps.txt`; do chkconfig $i off; service $i stop; done

Dedicated
yum install wget ; cd /usr/local/src/ && wget http://nixtree.com/download/free/services_dis_ded.txt && for i in `cat services_dis_ded.txt`; do chkconfig $i off; service $i stop; done
