I've got MySQL working now for Fremantle, but I'm struggling with the upstart
script for it. Probably due to my lack of understanding about upstart.
The script I'm working with (dummy start/stop events for testing):
-----------------------------------------------------------------------------------
description "MySQL server"
author "Tony Green"
start on xxx
stop on yyy
script
/usr/bin/mysqld_safe --user=mysql --skip-innodb
--pid-file=/var/lib/mysql/mysql.pid --log-error=/var/lib/mysql/error.log &
end script
post-stop script
if [ -f /var/lib/mysql/mysql.pid ]
then
kill `cat /var/lib/mysql/mysql.pid`
fi
end script
----------------------------------------------------------------------------------------
As it stands, "initctl emit xxx" or "/sbin/start mysqld" starts it, but because
the mysqld command is backgrounded, it runs through the post-stop script and
shuts the daemon down.
If I take out the backgrounding, it works as expected, BUT it blocks the
initctl command until I do "initctl emit yyy" from another console.
My worry is that if starting MySQL blocks whatever sends the signals during
startup, then anything else dependent on that signal won't be started until
MySQL stops.
Am I worrying unnecessarily? Or is there something glaringly obvious that I'm
doing wrong?
Thanks
