part 4. Cleaning unnecessary services

House cleaning (of unnecessary services)
I started by looking at what services are running and cleaning unnecessary. You can search Google to see what are the recommended services to shut down/keep in server environmet (in other words what is recommended to take off after a clean Redhat install). Removing them will improve both performance and security.

The command to run for seeing what services are currently on:

chkconfig  --list | grep “:on”

Create a script for swithing off unnecessary services (e.g. cleanup.sh), give it execute permissions (chmod +x cleanup.sh) and run it. Here are my commands just from the command line:

[root@soaserver2 bin]# chkconfig avahi-daemon off

[root@soaserver2 bin]# chkconfig bluetooth off

[root@soaserver2 bin]# chkconfig cups off

[root@soaserver2 bin]# chkconfig firstboot off

[root@soaserver2 bin]# chkconfig gpm off

[root@soaserver2 bin]# chkconfig haldaemon off
