brew install mysql
brew tap homebrew/services
brew services start mysql

If you run into this error using GUI tools, e.g. Sequel Pro:

Authentication plugin 'caching_sha2_password' cannot be loaded: dlopen(/usr/local/mysql/lib/plugin/caching_sha2_password.so, 2): image not found

Then do the following steps:

vi /usr/local/etc/my.cnf in section [mysqld] add line:

default-authentication-plugin=mysql_native_password

Login to mysql with mysql -u root -p:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_password';

And then restart:

brew services restart mysql

brew services stop mysql
