创建容器服务
# 创建容器服务，挂载数据文件和配置文件，运行以下命令
docker run -d --restart=always -e LANG=C.UTF-8 -e TZ=Asia/Shanghai -v /data/mysql_conf/my.cnf:/etc/my.cnf -v /data/mysql:/var/lib/mysql --name=mysql_master -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123123 harbor.dazhenyun.cn/repo/mysql:5.7
验证新建的容器化MySQL服务
# 进入容器 验证账号密码和字符集配置
bash-4.2# mysql -uroot -p123123
