Cannot remove MySQL installed via brew on MacOS Mojave: No available formula or cask with the name "mysql"

I installed MySQL 5.7.24 via Homebrew on MacOS Mojave v 10.14.4 per this gist. Now, I'm trying to remove it, but can't.
When I run brew remove mysql I get Error: No available formula or cask with the name "mysql".
I can run brew uninstall --force mysql and follow all the instructions from the post linked below, but I can't get brew remove mysql to work.
How to uninstall MySQL 5.6 when installed by brew on macOS?
Here are the steps I'm following:
# stop mysql
brew services stop mysql#5.7
# force uninstall
brew uninstall --force mysql
# check for running instances
ps -ax | grep mysql | grep -v grep
# no running process to kill
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/My*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
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 computer
After all of this, when I run mysql --version I get mysql Ver 14.14 Distrib 5.7.24, for osx10.9.
Also, I thought that maybe I needed to specify mysql#5.7 instead of just mysql, but I still get the same error.
It works with the version number.
brew uninstall --force mysql#5.7

"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 remove 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 /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
Optional, restart computer. I didn't.
2. INSTALL MYSQL
Install Mysql
brew install mysql
Set to run on startup
brew services start mysql

mariadb 10.1.21 mysql.server start error on macOS Sierra

I have just installed mariadb 10.1.21 latest with brew.
here is what i got with command
> mysql.server start
or
/usr/local/Cellar/mariadb/10.1.21/support-files/mysql.server start
whatever.
Starting MySQL
.170225 03:41:19 mysqld_safe Logging to '/usr/local/var/mysql/mac-615.err'.
170225 03:41:19 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
ERROR!
I do not know any reason why I cannot even start mysql daemon.
I had the same problem today. What I did was just uninstalling both mariaDB and mysql.
Remember doing a backup of your DB's in case you need it.
Just run the following commands in you terminal:
For mysql:
brew remove mysql
For mariaDB:
brew remove mariadb
Then, remove mysql folders and 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*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
vi /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*
Maybe, most of the folders and files won't exist, just to be sure they won't mess with the installation, do it.
After you have removed mysql and mariaDB files, run
brew cleanup
to ensure cache is gone.
Once it's done, you should be able to do a clean installation of mariadb with
brew install mariadb
Try your installation by running
mysql.server start
If hangs at starting, try restarting mysql with
mysql.server restart -f
By doing this, I was able to run mariadb, I hope it works for you.

MySQL will not run on OSX El capitan for any reason whatsoever

First of all let me start by saying that I have read and tried all approaches that I found on the web and stack overflow.
What I get when I try to run
mysql.server start
or
sudo /usr/local/mysql/support-files/mysql.server start
is
ERROR! The server quit without updating PID file (/usr/local/var/mysql/hostname.local.pid).
What I get when I try to run:
mysql
is
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
I also tried:
sudo mysqld_safe &
Clicking the mysql start button on system preferences.
Restart the computer
Reinstall mysql
Install older version of mysql
killall and then try to run mysql
sudo chmod -R 777 /usr/local/mysql/
`sudo chown -R mysql /var/lib/mysql/
rm /usr/local/var/mysql/localhost.err
sudo /usr/local/mysql/bin/mysqld_safe start
tried everything here: How to auto-load MySQL on startup on OS X Yosemite / El Capitan
I am out of ideas, I don't know what to do.
What I did to actually make it work:
killall -u username
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/My*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
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 the computer
brew doctor and fix any errors
brew update
brew install mysql
unset TMPDIR
mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
mysql.server start

Install MySQL 5.5 in Ubuntu 11.10

I have been downloaded the DEB package of mysql 5.5.23.
Install MySQL by the command as follows:
sudo dpkg -i mysql-5.5.23-debian6.0-x86_64.deb
The result said that installed successfully.
But when I type the command:
sudo service mysql start
Or
mysql
It shows me that "mysql: unrecognized service" or "mysql: command not found".
Besides, I can't find MySQL files in "/usr/include" or "/usr/bin"
Please help me. Thx.
Because MySQL 5.5.x is not packaged, in repositories only exist 5.1.x
