docker实际使用mysql例二

例二：定制化my.cnf与挂载卷

提前安装好docker

拉取官方镜像（我们这里选择5.7，如果不写后面的版本号则会自动拉取最新版）

docker pull mysql:5.7   # 拉取 mysql 5.7最新版本
docker pull mysql       # 拉取最新版mysql镜像
可以pull的版本根据官方版本号指定 可以参考https://hub.docker.com/_/mysql/

[root@A2 mysql5736]# docker pull mysql:5.7.34

[root@A2 mysql5736]# docker network create --driver bridge --subnet=10.0.0.0/24 --gateway=10.0.0.254 mynet

##直接pull的官方版镜像  都是rpm安装的；其镜像的默认mysql的gid与uid是999；docker安装后999的gid、uid已被其他用户占据；宿主机的挂载卷必须为999才具备权限
