环境说明

Docker	18.09.6
Mysql	5.7

安装

1. 拉取mysql镜像

[root@localhost ~]# docker pull mysql:5.7.21
5.7.21: Pulling from library/mysql

38680a9b47a8: Pull complete

Status: Downloaded newer image for mysql:5.7.21

[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql               5.7.21              5195076672a7        14 months ago       371MB

2. 创建container

[root@localhost ~]# docker run --name mysql_master -p 3301:3306 -d mysql:5.7.21
fd732d08d0914f1a3c7623c31e54f3902eb6ad8df2469b40c942bacf48b2b31e

如上container并未启动成功，原因：查看logs

[root@localhost ~]# docker logs mysql:5.7.21
Error: No such container: mysql:5.7.21
[root@localhost ~]# docker logs mysql_master
error: database is uninitialized and password option is not specified 
  You need to specify one of MYSQL_ROOT_PASSWORD, MYSQL_ALLOW_EMPTY_PASSWORD and MYSQL_RANDOM_ROOT_PASSWORD

指定环境变量：MYSQL_ROOT_PASSWORD，重新创建container

[root@localhost ~]# docker run --name mysql_master -p 3301:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7.21
01d8b16246ec93be2bf723b8ce7c71039c46826310bd1920dc48cc9c6e8feea4

//通过镜像 mysql:5.7.21 启动一个名为 mysql_master 的 MySQL 服务器，端口号是3306，映射的宿主机端口号是3301，root 账号密码是123456，-d 后台运行容器，并返回容器ID

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
01d8b16246ec        mysql:5.7.21        "docker-entrypoint.s…"   3 seconds ago       Up 2 seconds        0.0.0.0:3301->3306/tcp   mysql_master

测试连接成功
