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

Question

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:

1. 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
2. Reducing the query to most obvious and taking out functions: CREATE USER 'newuser';, still throws same error.
3. Repairing the mysql.procs_priv table
4. 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.

Answer 1

Completely removing mysql and reinstalling it worked (less than 15 mins).

1. UNINSTALL AND PURGE MYSQL FROM SYSTEM

1. Back up databases.
2. Stop and kill any MySQL processes. Check for processes with ps -ax | grep mysql

3. Uninstall mysql

   brew remove mysql
   brew cleanup
   

4. 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*
   

5. Unload previous auto login

   launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist 
   

6. Remove previous config. Delete the line MYSQLCOM=-YES- from /etc/hostconfig

7. Remove previous preferences

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

8. Optional, restart computer. I didn't.

2. INSTALL MYSQL

1. Install Mysql

   brew install mysql
   

2. Set to run on startup

   brew services start mysql
   

3. Secure the installation

   mysql_secure_installation
