I have a conflict with two programs in Ubuntu 10.04.

I have configured an init.d file that boots up a program. However, this program requires MySQL to be running before it starts. When I boot the machine, it's obvious that this script is being executed before MySQL has booted successfully.

I'm pretty inexperienced with Ubuntu's booting sequences and run levels. How can I make sure that MySQL is running before my init.d script is executed? I have heard that MySQL uses an alternative method of booting to init.d so I'm not sure how to go about this.

By the way: you could also have your script start mysql at boottime and not let mysql start itself during boot ;) – Rinzwind Jun 2 '12 at 18:52

10.04 came with the new upstart system.

Here is an example of a start/stop mysql upstart:

Have a look at the start on part:

# MySQL Service for Recorded Future
description     "MySQL Server"
author          "Anders Karlsson, Recorded Future"

start on (net-device-up
          and local-filesystems
          and runlevel [2345])
stop on runlevel [016]

expect fork
kill timeout 2

This tells the system that mysql has to start when this is true:

      and local-filesystems
      and runlevel [2345])

and has to stop when this is true:

runlevel [016]

So what you can do is create an upstart script for your program based on thise example and include a start on mysql telling it to start after mysql has started.

Thanks for your answer. In the script stanza is it possible to execute a bash script located in /etc/scripts/? Would the exec statement work with a bash script? – Kieran Jun 2 '12 at 19:08
@kieran yes ofcourse. You just use the whole path with the script name to execute it. – Rinzwind Jun 2 '12 at 19:13
Thanks for your help! Solved it with a start on started mysql upstart job. – Kieran Jun 2 '12 at 20:03
