CentOS

Hi,

I have my CentOS box running a backup server and I want it to automatically run two services at startup as a specific user. Any help with this would be greatly appreciated. Thanks!

Depends on the program(s) involved. You should really look at using systemd, but that too depends on the programs and how they behave.

From the shell (so a script too), you could use su <user> -c "<commands_to_run> > <log_file> 2>&1 " &

Where would I put that script for it to start that service at startup?

Systemd unit files should go in /etc/systemd/system and you can look in /usr/lib/systemd/system for examples of others that are already in use to find one similar to the things you want to do. I believe the correct thing to put in the unit file would be User=youruser

Well, after all that, I found out from the vendor that this has to be ran as root. :/

That's not good
Complain and tell them your giving them money for what amounts to the crappiest of crap....
