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
| RHEL 6 | RHEL7 |
|---|---|
| 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 |

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.
