1.在Mac中安装 docker 的mysql 镜像。

docker pull mysql/mysql-server
docker run --name mysql01 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql/mysql-server

另一种映射本地文件启动的方式（黑马程序员docker教程）

docker run -id -p 3306:3306 --name=mysql -v $PWD/conf:/etc/mysql/conf.d -v $PWD/logs:/logs -v $PWD/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:latest

2 .在虚拟机外面通过客户端访问docker安装的mysql ，连接失败
（1）进入镜像中的mysql（ti 后面的字符串是mysql镜像启动的容器ID或者用容器名字）

docker exec -ti 2cbb0f246353 /bin/bash

docker exec -it mysql /bin/bash

（2）登录mysql

mysql -u root -p

mysql -u root -p123456    密码明文登陆

（3）修改root 可以通过任何客户端连接

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

3、更新mysql中root用户的连接host

use mysql;
 update user set host = '%' where user = 'root' and host='localhost';
 grant all privileges on *.* to 'root'@'%' with grant option;
 或者
 GRANT ALL ON *.* TO 'root'@'%';  
 flush privileges;   

4.查看mysql容器ip -- 直接用这个ip访问好像不通，待解决，用127.0.0.1就可以

docker inspect --format '{{ .NetworkSettings.IPAddress }}' <container-ID> 
docker inspect --format '{{ .NetworkSettings.IPAddress }}' <容器名称>

注：这里查到的ip是docker的内网ip

5.连接docker中的mysql
可直接使用127.0.0.1连接

konsy@Konsy-MacBook-Pro ~ % mysql -uroot -p -h 127.0.0.1
Enter password:
