auto-run script at boot time in c7

[neuronetv]

I've been trawling google and this forum but can't see a way to get centos 7 to auto-run a script at boot time. Google has plenty about this on centos 5 and 6 but very little on centos 7.
The script is /root/red5-screens.sh, it works fine if run manually. What I've tried so far:

# chkconfig /root/red5-screens.sh on
error reading information on service /root/red5-screens.sh: No such file or directory
# chkconfig --add /root/red5-screens.sh
error reading information on service red5-screens.sh: No such file or directory

putting an entry in rc.local doesn'r work either. Thanks for any pointers.

/etc/rc.local or /etc/rc.d/rc.local are no longer executed by default due to systemd-changes.
to still use those, you need to make /etc/rc.d/rc.local executable:

Code: Select all

chmod +x /etc/rc.d/rc.local

If the script is executable, it should be executed at boot when you add a line containing

Code: Select all

/root/red5-screens.sh 

to /etc/rc.local (which is a symlink to /etc/rc.d/rc.local)
to be sure that your script is executable, just do a chmod +x /root/red5-screens.sh

To debug your problem, it would be a good idea to redirect the output of the script (if there is any) to a logfile to be sure if the script has been executed or not.

jensd thanks for this help, your suggestions worked.

This post helped me out as well with a similar situation, so thanks!

But, one further question: what is the non-rc.d way of running a script at startup for c7? As in, what is the "way of the future" with systemd for running scripts at startup?

You create a systemd unit file in /etc/systemd/system/ by looking at the ones in /usr/lib/systemd/system that do a similar job to the one you want to create.
