linux reboot and chkconfig

Setting up a new linux server pair for clients, I've did some things I haven't done in a while, so I thought I'd document them here so I'd remember in the future.

To set up a service in linux, use chkconfig. Running the chkconfig --list command shows all the potential daemons that are sitting in /etc/init.d/ and whether they are set to on|off|etc for each linux run level. The main run levels to set are 2,3,4,5. You can set the to on for http like this:
chkconfig --level 2345 httpd on

It's also a good idea to go to the script for that service in /etc/init.d (httpd in this case) and modify the chkconfig line at the top of the file to add those changed params.

To reboot the server you can run reboot. It actually calls shutdown -r or shutdown -h depending on the linux implementation.
