# mkdir -p mysql5.7/{data,conf,logs}
# cd conf 
# touch my.cnf

docker run --name mysql57 -p 33306:3306 -v /home/docker/mysql5.7/conf/my.cnf:/etc/mysql/my.cnf -v /home/docker/mysql5.7/data/:/var/lib/mysql -v /home/docker/mysql5.7/logs/:/var/log/mysql -e MYSQL_ROOT_PASSWORD=1qaz@WSX --restart=on-failure:3
