# instructions in http://fedoraproject.org/wiki/Systemd

#允许最大连接数

max_connections=200

#服务端使用的字符集默认为8比特编码的latin1字符集

5.启动容器

docker run --name mysql5.7 -p 3306:3306 --privileged=true --restart=always -d -v /usr/local/docker/mysql/logs:/logs -v /usr/local/docker/mysql/data:/var/lib/mysql -v  /usr/local/docker/mysql/conf/my.cnf:/etc/mysql/mysql.conf.d/mysqld.cnf -e MYSQL_ROOT_PASSWORD=Cc201818 mysql:5.7

6.查看容器启动状态

docker ps -a
