How to remove installation of MySQL on Mac OS X - mysql

I need to install older version of mysql server on mac os, but I have a newer version.
I tried to remove this newer installation (5.1), but when start old version install (5.0b) message "MySQL 5.0.51b-community for Mac OS X can't be installed in this disk. A newer version of this software alrady exists on this disk".
I can't recognize problem, because I remove all data of previouse install, but installer says no.
Mac OS version 10.6.


Try running also
sudo rm -rf /var/db/receipts/com.mysql.*


Try this, I had to struggle but this works for me!!!!!!!
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) sudo vi /etc/hostconfig (Remove line MYSQLCOM=-YES)
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /var/db/receipts/com.mysql.*


Test finding all files and folders with "mysql" in their name, take a look at them and see if they must be deleted as well.
Use the following command to find all the files.
sudo find / | grep -i mysql
You can scroll through the output if you put | less at the end (it won't show anything up until it finds something, just so you wouldn't think the command failed.) :-) You can write it as follows.
sudo find / | grep -i mysql | less
To remove the files/folders, you will have to run the following command (-f means force so you won't be able to restore the files and you won't be asked for a confirmation before they are deleted):
sudo rm -rf /path/to/file/or/folder
Hope this will be of any help.


I believe you can essentially just delete the /usr/local/mysql-Version/ and unlink the /usr/local/mysql directory. Getting rid of the system pref and the start up item might be harder, but I didn't install those so I can't help there.


You can use the built-in utility pkgutil to remove the package receipt:
sudo pkgutil --forget com.mysql.mysql


On Snow Leopard I had to additionally kill mysqld and did
rm /private/var/db/receipts/com.mysql.*
sudo rm -rf /Users//Library/StartupItems/MySQLCOM
sudo rm -rf /Users//Library/PreferencePanes/My*
sudo rm -rf /Users//Library/Receipts/mysql*
sudo rm -rf /Users//Library/Receipts/MySQL*

How to completely uninstall MySQL on MacOS

I followed another stackoverflow post to completely uninstall all instances of MySQL (I had 5..)
$ 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*
$ sudo rm -rf /var/db/receipts/com.mysql.mysql*
And reinstalled using
brew install mysql
but when I start the server, I have to put in the old root user password, which means it's still storing the passwords somewhere.
Brew prompted me change the password which I did, and then I got this error
... Failed! Error: File './mysql/user.MYD' not found (Errcode: 2 - No such file or directory)
So clearly mysql hasn't been completely uninstalled.

Ended up solving it by running
ps -ax | grep mysql
then going to each of the folders and removing any mysql data
then uninstalling XAMPP
then restarting computer
then
brew install mysql

"Cannot load from mysql.procs_priv. The table is probably corrupted" on Osx / homebrew

Problem:
Getting Cannot load from mysql.procs_priv. The table is probably corrupted when trying to create new mysql user.
Platform: OSX Yosemite, Homebrew
Tried all the below and DID NOT WORK:
Upgrading: mysql_upgrade -uroot -p
I had to use --force because of this: This installation of MySQL is already upgraded to 5.7.9, use --force if you still need to run mysql_upgrade
Next I had to use --skip-version-check because of this: Error: Server version (5.7.18) does not match with the version of the server (5.7.9) with which this program was built/distributed. You can use --skip-version-check to skip this check.
still didn't work after all that
Reducing the query to most obvious and taking out functions: CREATE USER 'newuser';, still throws same error.
Repairing the mysql.procs_priv table
Changing all the char columns in mysql.procs_priv to varchar, as suggested here. Well he suggested changing to text but that seemed too crazy for a core mysql table.

I think it will be better to use this:
mysql_upgrade -u root -p
Enter your password and wait a few seconds.

Completely removing mysql and reinstalling it worked (less than 15 mins).
1. UNINSTALL AND PURGE MYSQL FROM SYSTEM
Back up databases.
Stop and kill any MySQL processes. Check for processes with ps -ax | grep mysql
Uninstall mysql

brew cleanup
Remove all the residual files
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
Unload previous auto login
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Remove previous config. Delete the line MYSQLCOM=-YES- from /etc/hostconfig
Remove previous preferences
sudo rm -rf ~/Library/PreferencePanes/My*

sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*

How to check wheather mysql is intalled or not in mac machine?

I just wanna confirm wheather MySql is intalled in my mac machine or not. Actually, during its installation process I just messed up with the password configuration and after that I tried to reset its password but all to vain and I finally decided to uninstall it and do the installtion again from start. But before installing it again I just wanna confirm wheather the previous installation got cleared properlly or not. For unintalling mysql I have used following commands
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*

Execute the following command. If it says "command not found" it's not installed.
mysql -v

How install mysqldb on virtualenv on mac

I use Scrapy,
i tried to install mysql by brew install mysql
but i have this warning:
Warning: mysql-5.7.12 already installed
if mysql is already installed, why i can't see it in /etc/init.d/mysql

Is it possible you had previously not fully removed mysql and its components? One method of totally removing mysql from your system would be via the terminal. I found a pretty cut and dry way over at coolestguidesontheplanet:
sudo rm -rf /usr/local/mysq*
sudo rm /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
Navigate to then Edit /etc/hostconfig and remove the line with MYSQLCOM=-YES/NO-
rm -rf ~/Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
be sure to investigate as you go along and try to share what the issue was.

How do you uninstall MySQL from Mac OS X?

I accidentally installed the PowerPC version of MySQL on my Intel Mac in Snow Leopard, and it installed without a problem but of course doesn't run properly. I just didn't pay enough attention. Now when I try to install the correct x86 version it says that it can't install because a newer version is already installed. A Google query led me to perform these actions/delete these files to uninstall it:
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
rm -rf ~/Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
And finally removed the line MYSQLCOM=-YES- from /etc/hostconfig
They haven't seemed to help at all. I am still receiving the same message about there being a newer version. I tried installing an even newer version (the current Beta) and it also gave me the same message about a newer version already being installed. I can't uninstall it from the Prefs Pane because I never installed the PrefPane also.

Try running also
sudo rm -rf /var/db/receipts/com.mysql.*

I also had entries in:
/Library/Receipts/InstallHistory.plist
that i had to delete.

If you installed mysql through brew then we can use command to uninstall mysql.
$ brew uninstall mysql
Uninstalling /usr/local/Cellar/mysql/5.6.19...
This worked for me.

ps -ax | grep mysql
*stop and kill any MySQL processes
brew remove mysql
brew cleanup
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySql*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
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*
*restart your computer just to ensure any MySQL processes are killed
try to run mysql, it shouldn't work

OS version: 10.14.6
MYSQL version: 8.0.14
Goto System preferences -> MYSQL
Stop MySQL server
One option will be shown here to uninstall MYSQL 8 after stopping Mysql server

Aside from the long list of remove commands in your question, which seems quite comprehensive in my recent experience of exactly this issue, I found mysql.sock running in /private/var and removed that. I used
find / -name mysql -print 2> /dev/null
...to find anything that looked like a mysql directory or file and removed most of what came up (aside from Perl/Python access modules). You may also need to check that the daemon is not still running using Activity Monitor (or at the command line using ps -A). I found that mysqld was still running even after deleting the files.

I also had a config file at /etc/my.cnf that I needed to delete on my Mac OS X Snow Leopard install

It might be overkill but your MySQL command history can also be wiped from:
~/.mysql_history

You need to identify where MySQL was installed to before attempting to delete it.
I always use the Hivelogic guide to installing under Mac OS X which builds MySQL from source. When setting up the build you can specify a directory under which to install MySQL with the --prefix parameter. You should make sure the directory does not exist and attempt to install from source.
./configure --prefix=/usr/local/mysql --with-extra-charsets=complex \
--enable-thread-safe-client --enable-local-infile --enable-shared \
--with-plugins=innobase

You should also check /var/db/receipts and remove all entries that contain com.mysql.*
Using sudo rm -rf /var/db/receipts/com.mysql.* didn't work for me. I had to go into var/db/receipts and delete each one seperately.

For me, I had installed MariaDB years ago using homebrew. Correct uninstall procedure was:
brew uninstall mariadb.

I also found
/Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
after using all of the other answers here to uninstall MySQL Community Server 8.0.15 from OS X 10.10.

This did the job for me:
brew uninstall mysql

brew uninstall --force mysql#<version_no>
exmample
brew uninstall --force mysql#5.7
to get version check cd /usr/local/Cellar

Remove MySQL completely
Open the Terminal
Use mysqldump to backup your databases
Check for MySQL processes with:
ps -ax | grep mysql
Stop and kill any MySQL processes
Analyze MySQL on HomeBrew:
brew remove mysql
brew cleanup
Remove files:
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
Unload previous MySQL Auto-Login:
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Remove previous MySQL Configuration:
subl /etc/hostconfig`
# Remove the line MYSQLCOM=-YES-
Remove previous MySQL Preferences:
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*
Restart your computer just to ensure any MySQL processes are killed
Try to run mysql, it shouldn't work

sudo find / | grep -i mysql
This worked like a charm for me. Just went through the list and ensured that anything MySQL related was deleted.
