mysql 8.0 e3fcc9e1cc04 5 hours ago 544MB启动
[root@iZuf68t6hada0ayijajs45Z svdb]# docker run --name mysql --restart=always \
> -v /data/svdb/mysql/conf/my.cnf:/etc/mysql/my.cnf \
> -v /data/svdb/mysql/data:/var/lib/mysql \
> -p 3317:3306 \
> -e MYSQL_ROOT_PASSWORD="root" \
> -e TZ=Asia/Shanghai \
> -d mysql:8.0 --lower-case-table-names=11、-name mysql ： 给Mysql容器起一个别名
2、-restart=always：开机启动
3、-v：将容器的文件挂载到宿主目录，避免以后在卸载docker的时候，数据丢失。
如：-v /data/svdb/mysql/conf/my.cnf:/etc/mysql/my.cnf 是将容器的/etc/mysql/my.cnf 挂载到主机的/data/svdb/mysql/conf/my.cnf
4、-e MYSQL_ROOT_PASSWORD：设置密码
5、-p 3317:3306：mysql端口映射到主机的3317端口
6、-d mysql:8.0：后台运行容器
7、--lower-case-table-names=1一定要加，mysql8.0关方规定只有在初始化的时候给与配置，后续不管在my.cnf还是重新docker run --lower都无效（重新docker run --lower必须保证/var/lib/mysql仓库是干净的才可以，不然出错）
