Docker安装连接MySql

1、拉取 mysql5.6 镜像文件：

[root@localhost ~]# docker pull mysql:5.6
Trying to pull repository docker.io/library/mysql ...

Status: Downloaded newer image for docker.io/mysql:5.6

2、创建并运行一个 mysql5.6 的容器：

[root@localhost ~]# docker run --name mysql56 -e MYSQL_ROOT_PASSWORD=root -d -p 3306:3306 mysql:5.6 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

3、通过 mysql 容器提供的客户端功能测试连接 mysql 容器：

[root@localhost ~]# docker run -it --link mysql56 --rm mysql:5.6 sh -c 'exec mysql -hmysql56 -uroot -proot'
mysql: [Warning] Using a password on the command line interface can be insecure.
