How to remove MySQL completely Mac OS X Leopard

Written on 23-10-2008 – 20:16:25 | by Tom Keur


After I’ve been searching alot I finally mananged it to delete MySQL from my Macbook pro.

The steps:

First you need to edit the file in: /etc/hostconfig and remove the line

Since this is a system file I advise you to open it with nano in terminal:

  1. Open Terminal
  2. sudo nano /etc/hostconfig
  3. Enter your password if you’re not authed yet.
  4. Delete the following line: “MYSQLCOM=-YES-”
  5. CTRL+X (This is the command for closing NANO, Enter the “Y” key to save the file and exit nano).

Second step:

Make sure MySQL is not running.

  1. Open Terminal and copy and paste and run the following commands:
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm /etc/my.cnf

MySQL is now removed from your MAC.

Edit 26-02-2009:  Maarten van der Pee wrote a comment that it’s allso needed to delete the my.conf, I added it to the list of commands. Thanks Maarten!

    I spent hours trying to remove mysql from my MacBook in order to re-install. None of the information that I found online seemed to work until I tried your method. Thank you very much!

    Don’t forget sudo rm /etc/my.cnf
    If you want to try out MAMP you get mysql socket problems if you don’t delete this file

    Just wanted to say thank. Like Fabian, I spent hours trying to find a way to remove it, all I found was people asking, and everyone else telling them not to. :(

    You were a BIG BIG BIG help.

    Cheers Mate

    In your code sample you have my.cnf. is that supposed to be my.conf?

    The writers of mysql should just make it easier to uninstall their product. I have no idea why they have made that so difficult to do.

    Another place I went to before this forum didn’t say to delete the MYSQLCOM=-YES- line beforehand….I went to do this after having already completed all the other steps. Now MYSQLCOM=-YES- can’t be deleted it seems. I think everything else is uninstalled?? I am new to this, so I’m having a hard time trying to figure out what’s wrong. Any help would be appreciated!!

    Thanks for this. I’m not terminal savy and rely on bbedit a lot. Though it can see system files it can’t delete them.
    Thanks again.

    Thanks but add this one:
    sudo rm -rf /var/db/receipts/com.mysql.*
    I can’t install another version before doing that.

    I have no experience using Terminal. I am trying to erase MySQL also. I went into terminal and typed “sudo nano /etc/hostconfig, then entered my password and got the following:
    Last login: Thu May 27 22:26:54 on ttys000
    Katie-Bradshaws-MacBook-Pro:~ kbmacbk$
    Katie-Bradshaws-MacBook-Pro:~ kbmacbk$ sudo nano /etc/hostconfig

    GNU nano 2.0.6 File: /etc/hostconfig Modified

    # This file is going away

    ^G Get Help ^O WriteOut ^R Read File ^Y Prev Page ^K Cut Text ^C Cur Pos
    ^X Exit ^J Justify ^W Where Is ^V Next Page ^U UnCut Text^T To Spell

    I highlighted the line “MYSQLCOM=-YES-, and then hit the delete button and it won’t go away. Am I suppose to type “^K” to cut text? How do I delete that line? I do hope someone sees this and can help. I’d be much obliged. Thanks!

    Thanks a lot for posting that. its so going to help me and my whole team here.
    Would you also have the solution to the problem of granting access to the users in Mysql.

    when i run the follwing command from the root user :
    GRANT ALL PRIVILEGES ON *.* TO ‘store_user’@'localhost’ IDENTIFIED BY ‘store_user123′ WITH GRANT OPTION ;

    and try loggin in through the store_user i get the following error :
    ERROR 1045 (28000): Access denied for user ‘store_user’@'localhost’ (using password: NO)

    Please share your views.
    Thanks once again…

    sudo rm /etc/my.conf gives me ‘No such file or directory’ – I’m a bit new to all this so can anyone suggest what it means please?

    Many thanks

    I can’t remove MySQL 5.5.7 T-T
    Help !

  32. By Bruno Windels on Dec 17, 2010 | Reply

    It seems that the installer since a certain version also keeps files in /private/var/db/receipts/ that all start with com.mysql , to be specific


    I have noticed problems when using the above instructions to reinstall a previous version. The installer won’t let you continue.

    If you remove the above files (at your own risk), the installer let’s you continue.

    sudo rm /etc/my.conf gives me ‘No such file or directory’ – what it means please?

    for 5.5 you also need to run
    sudo rm /var/db/dslocal/nodes/Default/groups/_mysql.plist
    sudo rm /var/db/dslocal/nodes/Default/users/_mysql.plist
    sudo rm /var/db/receipts/
    sudo rm /var/db/receipts/com.mysql.mysql..plist

    That’s really worked on my mac.

    I’ve installed the MySQL by the dmg archive but it seems does not work, after uninstall it, i will try again. I hope this time it would turn to be okay.

    thanks anyway.

    Thank you good sir, you are still helping people lo these many years after you first posted this. I was trying to fix a botched MAMP PRO install that had an issue with a botched uninstall of MySQL from months ago. This worked beautifully!

    Thanks – very clear instructions – worked a treat.
    rm commands that flicked up an error I just went to the location and removed MySql associated files.
    I used vi to edit the hostconfig file:
    sudo vi /etc/hostconfig [‘i’ for insert mode then delete the MySql Line then ‘esc’ button to exit insert mode then ‘:wq’ to write and quit.

    As was described before, for Lion also need to do:
    sudo rm /var/db/receipts/com.mysql*
    sudo rm /var/db/dslocal/nodes/Default/groups/_mysql.plist
    sudo rm /var/db/dslocal/nodes/Default/users/_mysql.plist
    (if mysql was running)
    sudo rm /private/tmp/mysql.sock
    And may be also:
    sudo rm /System/Library/DirectoryServices/DefaultLocalDB/Default/groups/_mysql.plist
    sudo rm /System/Library/DirectoryServices/DefaultLocalDB/Default/users/_mysql.plist
    sudo rm /Library/Logs/DiagnosticReports/mysqld_*

    I follow the instruction, but instead of “MYSQLCOM=-YES-” I faced with “MYSQLCOM=-No-”. What should I do now? Thanks in advance for helping me.

    if you have several users, and especially administrators, make sure you do this process for EACH user! Spent about 3 hours scratching my head.

    If I have to read one more `killall -9 mysqld`, I dunno :’(
    Thx for a great post!

    “sudo rm -rf /Library/PreferencePanes/My*
    ” is dangerous. Replace by “sudo rm -rf /Library/PreferencePanes/MySQL*”
