本地创建mysql的映射目录
在正式的启动Mysql镜像之前进行映射目录的配置。
mkdir -p /opt/mysql/data /opt/mysql/logs /opt/mysql/conf在/root/mysql/conf中创建 *.cnf 文件（叫什么都行）。这里以个人创建的mysql.conf为例：
touch mysql.conf创建容器，将数据，日志,配置文件映射到本机，注意这里的root密码为root：
docker run -p 13306:3306 --name mysql -v /opt/mysql/conf:/etc/mysql/conf.d -v /opt/mysql/logs:/logs -v /opt/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7运行之后，我们执行docker ps查看当前运行的mysql镜像：
[zxd@localhost conf]$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e95a0bc7b4a4 mysql:5.7 "docker-entrypoint.s…" About a minute ago Up About a minute 33060/tcp, 0.0.0.0:13306->3306/tcp, :::13306->3306/tcp mysql相关运行参数如下：
-d: 后台运行容器
-p 将容器的端口映射到本机的端口
-v 将主机目录挂载到容器的目录
-e 设置参数
运行之后我们执行下面的命令查看：
[zxd@localhost conf]$ mysql -uroot -proot -P 13306

最后查看/opt/mysql/data目录是否有数据文件：
[zxd@localhost conf]$ sudo ls /opt/mysql/data
auto.cnf client-cert.pem ibdata1 ibtmp1 performance_schema server-cert.pem
ca-key.pem client-key.pem ib_logfile0 mysql private_key.pem server-key.pem
ca.pem ib_buffer_pool ib_logfile1 mysql.sock public_key.pem sys运行容器
docker run -p 13306:3306 --name mysql57 --restart=always -v /opt/mysql/conf:/etc/mysql/conf.d -v /opt/mysql/logs:/logs -v /opt/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7
