This is a document to help keeping tab on which services have been ported to systemd native files...
Services
| Package name | SysV file | Native Systemd | Ported | Notes |
|---|---|---|---|---|
| ls -al /etc/rc.d/init.d | systemctl --all --type=service | Used to list the services that can be started or stopped | ||
| chkconfig frobozz | sytemctl is-enabled frobozz.service | Used to check whether a service is configured to start or not in the current environment. | ||
| chkconfig frobozz --list | Used to list what levels this service is configured on or off | |||
| chkconfig frobozz --level 345 on | systemctl enable frobozz.service OR ln -s ../frobozz.service /lib/systemd/system/runlevel3.target.wants/ to configure runlevels manually | Turn the service on for the next reboot | ||
| chkconfig frobozz --level 345 off | systemctl disable frobozz.service OR rm /lib/systemd/system/runlevel3.target.wants/frobozz.service to configure runlevels manually | Turn the service off for the next reboot | ||
| service frobozz start | systemctl start frobozz.service OR service frobozz start | Used to start a service (not reboot persistent) | ||
| service frobozz stop | systemctl stop frobozz.service OR service frobozz stop | Used to stop a service (not reboot persistent) | ||
| service frobozz restart | systemctl restart frobozz.service OR service frobozz restart | Used to stop and then start a service | ||
| service frobozz reload | systemctl reload frobozz.service OR service frobozz reload | When supported, reloads the config file without interrupting pending operations. | ||
| service frobozz condrestart | systemctl reload-or-restart frobozz.service OR systemctl condrestart frobozz.service OR service frobozz condrestart | When supported, restarts if the service is already running. |
In SysVinit, services can define arbitrary commands. Examples would be service iptables panic, or service httpd graceful. Native systemd services do not have this ability.
Any service that defines an additional command in this way would need to define some other, service-specific, way to accomplish this task when writing a native systemd service definition.
Check the package-specific release notes for any services that may have done this.Runlevels
runlevels are used with telinit and on the kernel command line in SystemVinit. These traditional ways of switching runlevels still work with systemd, but additionally, the following can be used instead.
| SystemVinit Runlevel | Systemd Target | Notes |
|---|---|---|
| 0 | runlevel0.target, poweroff.target | Halt the system. |
| 1, s, single | runlevel1.target, rescue.target | Single user mode. |
| 2, 4 | runlevel2.target, runlevel4.target, multi-user.target | User-defined/Site-specific runlevels. By default, identical to 3. |
| 3 | runlevel3.target, multi-user.target | Multi-user, non-graphical. Users can usually login via multiple consoles or via the network. |
| 5 | runlevel5.target, graphical.target | Multi-user, graphical. Usually has all the services of runlevel 3 plus a graphical login. |
| 6 | runlevel6.target, reboot.target | Reboot |
| emergency | emergency.target | Emergency shell |
Changing runlevels:
| SystemVinit Command | Systemd Command | Notes |
|---|---|---|
| telinit 3 | systemctl isolate runlevel3.target OR telinit 3 | Change to multi-user run level. |
| sed s/^id:.*:initdefault:/id:3:initdefault:/ | ln -sf /lib/systemd/systemd/multi-user.target /etc/systemd/system/default.target | Set to use multi-user runlevel on next reboot. |
