How do you stop MySQL on a Mac OS install?

Question

I installed MySQL via MacPorts. What is the command I need to stop the server (I need to test how my application behave when MySQL is dead)?

Answer 1

I installed mysql5 and mysql55 over macports. For me the mentioned files here are located at the following places:

(mysql55-server) /opt/local/etc/LaunchDaemons/org.macports.mysql55-server/org.macports.mysql55-server.plist

(mysql5) /opt/local/etc/LaunchDaemons/org.macports.mysql5/org.macports.mysql5.plist

So stopping for these works like this:

mysql55-server:

sudo launchctl unload -w /opt/local/etc/LaunchDaemons/org.macports.mysql55-server/org.macports.mysql55-server.plist

mysql5:

sudo launchctl unload -w /opt/local/etc/LaunchDaemons/org.macports.mysql5/org.macports.mysql5.plist 

You can check if the service is still running with:

ps ax | grep mysql

Further you can check the log files in my case here:

mysql55-server

sudo tail -n 100 /opt/local/var/db/mysql55/-MacBook-Pro.local.err
...
130213 08:56:41 mysqld_safe mysqld from pid file /opt/local/var/db/mysql55/-MacBook-Pro.local.pid ended

mysql5:

sudo tail -n 100 /opt/local/var/db/mysql5/-MacBook-Pro.local.err
...
130213 09:23:57  mysqld ended
