RHEL 7 and Systemd

Hello again

So with much anticipation from the community Red Hat has released RHEL 7 , and with it an Enterprise Linux Disto that actually ships Systemd , the replacement for the old style SysV init . I am not saying this is good or bad, traditionally people don’t like change so this is a bit theme right now, in any case here is a Cheat Sheet of the old RHEL 6 equivalents

chkconfig servicename on systemctl enable servicename
chkconfig servicename off systemctl disable servicename
chkconfig servicename on systemctl enable servicename
chkconfig –list systemctl list-unit-files –type=service
service servicename start systemctl start servicename
service servicename stop systemctl stop servicename

You can also check the more in depth cheat sheet here

One of the things that I found to be a bit strange at the beginning was hostnamectl , that as you might have guesses controlls the hostname , so now changing the hostname for your server is something like

#hostnamectl –static set-hostname myserver.mydomain.com

And yes there is also nmcli and firewallctl but that is another article by itself.

Next: nmcli or How to manage your network on RHEL 7
