systemctl startup/shutdown script

Yummy · #1 06-10-2015, 04:57 PM

Does anyone have an example of a systemd startup and shutdown script?

Fedora/CentOS move from sys-v to systemd has left me feeling a bit lost.

Thank you

Here are what I'm using for mine

Code:

# cat /usr/lib/systemd/system/eqemu-world.service 
[Unit]
Description=EQ Emulator World server
After=network.target

[Service]
Type=simple
User=eq
Group=users
WorkingDirectory=/home/eq/server
ExecStartPre=/home/eq/server/shared_memory
ExecStart=/home/eq/server/world

[Install]
WantedBy=multi-user.target

Code:

# cat /usr/lib/systemd/system/eqemu-zones.service 
[Unit]
Description=EQ Emulator Zone server
After=network.target
After=eqemu-world.service
Requires=eqemu-world.service

[Service]
Type=simple
User=eq
Group=users
WorkingDirectory=/home/eq/server
ExecStart=/home/eq/server/eqlaunch zone

[Install]
WantedBy=multi-user.target

EDIT: This is on CentOS 7. I'd imagine would work fine on Fedora without modifying (beyond changing the paths, that is)

Would this work on Ubuntu? And how is the service called at bootup?

I have systemd with systemd-shim.list, but the directory structure in the above scripts are different.

I had to make some minor changes but your examples were perfect as a starting point. You saved me hours and hours. Thank you!

For Fedora 22, I chose to create five systemd scripts. The those unfamiliar with the process, I have provided details here https://blog-harmonson.rhcloud.com/2...erver-minimal/ under the section titled Systemd Scripts.
