1，安装支持rancher 的docker，方便后期做集群管理

curl https://releases.rancher.com/install-docker/18.09.sh | sh

2，docker安装mysql，映射本地目录

	docker run -p 3306:3306 --name mysql \
	-v /usr/local/docker/mysql/conf:/etc/mysql \
	-v /usr/local/docker/mysql/logs:/var/log/mysql \
	-v /usr/local/docker/mysql/data:/var/lib/mysql \
	-e MYSQL_ROOT_PASSWORD=123456 \
	-d mysql:5.7

3，测试mysql链接

docker exec -it mysql bash
mysql -uroot -p123456

4,添加用户并授权（root登录mysql控制台执行）

• 添加用户

create user ljbb identified by 'ljbb@123';
# create user 账号 identified by '密码';

• 授权，刷新

grant all privileges on lijia_ehr.* to ljbb@'localhost' identified by 'ljbb@123';  #授权
flush privileges;  #刷新
show grants for 'ljbb';  #查看授权

• 退出后用新建用户测试登录是否成功
