使用Docker安装Mysql

最近使用阿里云服务器，学习一下Docker，今天学着使用Docker安装MySQL。

首先，从阿里云的Docker Hub 上pull一个MySQL的image.

[centos@loovelj~]$ docker pull registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7
5.7: Pulling from acs-sample/mysql
d4bce7fd68df: Pull complete

Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7

查看下载镜像，就会看到已经有了

[centos@loovelj~]$ docker images
REPOSITORY                                           TAG                 IMAGE ID            CREATED             SIZE

名字太长，修改为短的tag

[centos@loovelj~]$ docker tag registry.cn-hangzhou.aliyuncs.com/acs-sample/mysql:5.7 mysql:5.7 
[centos@loovelj~]$ docker images
REPOSITORY                                           TAG                 IMAGE ID            CREATED             SIZE
test/ubuntu                                          v1.0                523e7db0e264        12 minutes ago      98.3MB

根据镜像创建容器

[centos@loovelj~]$ docker create -it mysql:5.7
62c975b37ad25b03914eb61e05088019f37ff9cb049a682ac02f20fac1761a4d

启动MySQL容器

[centos@loovelj~]$ docker run --name mysqlserver -e MYSQL_ROOT_PASSWORD=sgcc -d -i -p 3306:3306  mysql:5.7
2a7a85124400be6fd47e0d97cf5d602456b1db1a11c6331747fe662481eea537
[centos@loovelj~]$ docker ps

进入MySQL终端

[centos@liujun ~]$ docker exec -it  2a7a85124400  /bin/bash
root@2a7a85124400:/# mysql -h 127.0.0.1 -u root -p
