　　重新创建运行mysql5.7.41容器,并挂载外部配置文件 

[root@VM-12-9-opencloudos hj_files]# podman run -d --privileged=true --name hj_mysql57 \
> -p 3307:3307 -v /hj_files/hj_mysql57/data:/var/lib/mysql \

 navicat 连接成功~~~5.7.41~~~over

继续8.0.32安装   简单需求: 配置文件,数据挂载到外部文件.端口号改成3308,密码访问

podman run -d --privileged=true --name hj_mysql80 \
