[root@ghost /]# /etc/rc.d/mysqld restart

[DONE]

[FAIL]

I can use the 'start' and 'stop' commands for /etc/rc.d/mysqld but
'restart' for some reason fails and this concerns me. Can anyone help
me understand what is wrong?

When you stop MySQL, the kill command completes immediately, while MySQL
is still doing shutdown tasks to make sure the database is in a
consistent state. As MySQL is still running when you try to start it, it
will fail to do so.
There's 2 ways to fix this:
- use mysqladmin shutdown, needs a user in the database with process
privileges, this is the way used by debian
- implement a loop that waits for MySQL to shutdown after executing the
kill command. This is what the upstream MySQL start/stop script does.


/etc/rc.d/mysqld could be fixed then
This task depends upon

increment the sleep to 5 seconds fixes this. I'll commit this change to trunk ASAP

Sleeping for 5 seconds doesn't cut it. If you have a very big transaction log configured, MySQL will take far more than 5 seconds to shutdown.
