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

Use:

sudo mysqladmin shutdown --user=*user* --password=*password*

One could probably get away with not using sudo. The user could be root for example (that is, the MySQL root user).

Answer 2

Well, if all else fails, you could just take the ruthless approach and kill the process running MySQL manually.

That is,

ps -Af

to list all processes, then do "kill <pid>" where <pid> is the process id of the MySQL daemon (mysqld).

Answer 3

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/<MyName>-MacBook-Pro.local.err
...
130213 08:56:41 mysqld_safe mysqld from pid file /opt/local/var/db/mysql55/<MyName>-MacBook-Pro.local.pid ended

mysql5:

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

Answer 4

There are different cases depending on whether you installed MySQL with the official binary installer, using MacPorts, or using Homebrew:

Homebrew

brew services start mysql
brew services stop mysql
brew services restart mysql

MacPorts

sudo port load mysql57-server
sudo port unload mysql57-server

Note: this is persistent after a reboot.

Binary installer

sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM restart

Answer 5

Try

sudo <path to mysql>/support-files/mysql.server start
sudo <path to mysql>/support-files/mysql.server stop

Else try:

sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop<br>
sudo /Library/StartupItems/MySQLCOM/MySQLCOM restart

However, I found that the second option only worked (OS X 10.6, MySQL 5.1.50) if the .plist has been loaded with:

sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysqld.plist

PS: I also found that I needed to unload the .plist to get an unrelated install of MAMP-MySQL to start / stop correctly. After running running this, MAMP-MySQL starts just fine:

sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysqld.plist

Answer 6

On my mac osx yosemite 10.10. This command worked:

sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysql.plist
sudo launchctl unload -w /Library/LaunchDaemons/com.mysql.mysql.plist

You can find your mysql file in folder /Library/LaunchDaemons/ to run
