1.建立mysql映象

docker run --name some-mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag

2.進入mysql容器

docker exec -it some-mysql bash

3.檢視mysql啟動狀態

service mysql stutas
# 啟動
service mysql start

4.設定mysql遠端連線

use mysql

update user set authentication_string = password('root') where
 
 user = 'root';

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
