Completely uninstall mysql on Mac OS X

Recently installed mysql under Mac, finally installed the environment and debugged it all afternoon! I can connect tomcat and mysql on eclipse, but I don't know why mysql doesn't start well the next day. I couldn't get it right, so I unloaded it. As a result, it could not be reinstalled because the old mysql was not uninstalled cleanly. I almost collapsed by this.

Here is my experience to share with you:

How can you completely uninstall mysql and delete it from your Mac (including all databases) to do the following:

Open the terminal window

Use mysqldump to back up your database into text files!

Stop the database server

Sudo rm / usr/local/mysql

Sudo rm-rf / usr/local/mysql*

Sudo rm-rf / Library/StartupItems/MySQLCOM

Sudo rm-rf / Library/PreferencePanes/My*

Edit / etc/hostconfig and remove the line MYSQLCOM=-YES-

Rm-rf ~ / Library/PreferencePanes/My*

Sudo rm-rf / Library/Receipts/mysql*

Sudo rm-rf / Library/Receipts/MySQL*

Sudo rm-rf / private/var/db/receipts/*mysql*

The last three lines are particularly important, otherwise, you cannot install an old version of MySQL, even if you think you have completely deleted the new version!
