How to stop MySql process running permanently?

I want to stop MySql running on my local machine ,because I have it conflicted with mySql in docker container.

I get this ,(not sure if it's a "real" mysql process )

ps auxwww |grep mysql
root     13277  0.0  0.0  13192  2168 pts/3    S+   22:02   0:00 grep --colour=auto mysql

Have tried :

service mysql stop

echo "manual" >> /etc/init/mysql.override
