How To Restart MySQL
Restarting a MySQL server instance is easy. How you do this depends on the system that you are running your database on.
For systemd based systems you can restart like this:
sudo systemctl restart mysql
And stop/start like this:
sudo systemctl stop mysql
sudo systemctl start mysql
If you have a system with SysVinit you can restart like this:
sudo service mysql restart
And stop/start like this:
sudo service mysql stop
sudo service mysql start
On MacOS you could restart MySQL with this command:
sudo /usr/local/mysql/support-files/mysql.server restart
