CentOS Amazon EC2 – Adding Script to Run at Startup Without rc.local

amazon ec2centos

I'd like to run a script at startup without actually adding it as a command to rc.local, just by copying a script somewhere.

I know in theory I can put it into /etc/init.d but that's really for services, not scripts that are just supposed to run on startup.

I know about the cron @reboot option as well but I really would prefer something where I just copy a script over to a directory and then can forget about it.

Basically, in the same way you can just put a file in /etc/cron.daily or /etc/logrotate.d I'm wondering if there's an equivalent folder where you just put in a file and it runs at startup.

If necessary I'm willing to install a program that does this for you, so long as it's stable.

I've managed this with the following which works well.

Create /etc/cron.d/reboot with the contents below. Note - It's been a while, you should check syntax.

@reboot root run-parts  /etc/cron.reboot

Create a folder /etc/cron.reboot

From there it's a matter of dropping files in to the cron.reboot folder.

Make sure your script is runnable. (chmod +x)

But why would you use a script to mount it? You can add it to /etc/fstab.

I think your problem is in /srv/rhodecode/start.sh. It is currently starting paster as a separate background process and then immediately exiting. This poses a problem for your init script, which expects start.sh to itself be the long-running daemon process to be managed.

Thus, try changing the last line of /srv/rhodecode/start.sh to read as follows:

exec paster serve production.ini 1> debug.log 2> error.log

Using exec makes start.sh become paster, which is then daemonized by the daemon command in the init script.
