docker run -p 3306:3306 --name mysql001 --restart=always -v /data/conf:/etc/my.cnf.d -v /data/mysql_data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7.21 --character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci

参数说明如下：

-p 3306:3306  #将容器的3306端口映射到主机的3306端口
--name mysql001  #容器的名字为mysql001
--restart=always  #在宿主机重启后或者Docker服务重启后自动启动容器，
no #不重启(不带restart参数时，默认不重启)
on-failure  #退出状态非0时重启
always  #始终重启
-v /data/conf:/etc/my.cnf.d  #将/data/conf目录映射到/etc/my.cnf.d下面 
-v /data/mysql_data:/var/lib/mysql  #将/data/mysql目录映射到/var/lib/mysql下面
-e MYSQL_ROOT_PASSWORD=123456 #设置root初始密码为123456
 -d mysql:5.7.21  #后台运行容器，并返回容器ID
--character-set-server=utf8mb4 --collation-server=utf8mb4_general_ci   #设置编码为utf8mb4
