搭建MySQL
一、选取可用MySQL镜像
查看可用镜像有两种方式
1、直接在Docker的 官方镜像仓库 搜索可用的镜像（推荐：因为可以看到可用的版本tag，方便选取不同版本）。
2、使用Docker指令搜索可用的镜像。
[root@ ~]# docker search mysql

二、拉取镜像
tag表示MySQL不同版本的标签。
$ docker pull mysql:tag
[root@ ~]# docker pull mysql:5.7
5.7: Pulling from library/mysql
6ae821421a7d: Pull complete
a9e976e3aa6d: Pull complete
e3735e44a020: Pull complete

Digest: sha256:8c15b2612051244d0a2b6ceb6f9bf82ddc0e909555c1067c098e5f935e2751a7
Status: Downloaded newer image for mysql:5.7
拉取完成后，通过docker images命令查看镜像目录，如下表示下载成功
[root@ ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mysql 5.7 e47e309f72c8 13 days ago 372MB
三、启动MySQL服务实例
$ docker run --name some-mysql -p host-port:docker-port -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag
–name some-mysql：表示给这个容器命名为some-mysql；
-p host-port:docker-port：表示把主机的端口映射到容器的端口
-e MYSQL_ROOT_PASSWORD=my-secret-pw：表示设置root用户的密码为my-secret-pw；
-d 表示在后台运行容器；
tag表示MySQL的版本；
[root@iZm5ee0h5tkrzzli5jd8z5Z ~]# docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7
接着你可以使用docker container ls -a或docker ps -a查看启动的实例。
[root@iZm5ee0h5tkrzzli5jd8z5Z ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3b78098cb843 mysql:5.7 "docker-entrypoint.s…" 3 seconds ago Up 2 seconds 0.0.0.0:3306->3306/tcp, 33060/tcp mysql
这样一来再设置好阿里云的安全组就可以使用Navicat链接和操作容器里的MySQL里。
