install mysql by docker

 docker run -p 3306:3306 --name mysql_lmt  -v /var/lib/docker/volumes/data/_data//mysql/conf:/etc/mysql/conf.d  -v /var/lib/docker/volumes/data/_data/mysql/logs:/logs -v /var/lib/docker/volumes/data/_data/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456  -d mysql

进入docker mysql
docker exec -it 2a7a85124400 /bin/bash
mysql -h 127.0.0.1 -u root -p
执行授权命令，此处已root用户为例
create user root@'%' identified by '123456';
grant all privileges on databas_name.* to root@'%';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
