Docker mysql stores data in local directory

Docker  MySQL  stores data in a local directory, which is very simple, just map the local directory to the container

1. Add the -v parameter

$ docker run -d-e MYSQL_ROOT_PASSWORD=admin --name mysql -v /data/mysql/data:/var/lib/mysql -p3306:3306 mysql:5.6

You can also specify a configuration file

 

docker run -d-e MYSQL_ROOT_PASSWORD=admin --name mysql -v /data/mysql/my.cnf:/etc/mysql/my.cnf -v /data/mysql/data:/var/lib/mysql -p3306:3306 mysql
