mysql 日常记录

---------------------------5.7-------------------------------

docker中连接mysql容器时，需要ip地址的话 docker inspect 容器名 查看

yin5th@yin5th:~/code/docker/compose-golang$ docker inspect compose-golang_mysql_1 | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "",
                    "IPAddress": "172.22.0.2",
yin5th@yin5th:~/code/docker/compose-golang$

开启远程访问权限。

    a.docker exec -it mysql容器名 /bin/bash

    b.mysql -uroot -p 

    c.进入mysql数据库（use mysql;）执行下列命令： （赋予root用户所有ip连接数据库的权限）

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

-----------------------myql 8.0+ -----------------------------------------------

如果mysql版本是8.0以上在授权的语句中需要去掉 IDENTIFIED BY ‘password’;否则会报语法错误

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

mysql 8.0中，第一次创建用户时，可能会报错

ERROR 1146 (42S02): Table 'mysql.role_edges' doesn't exist

需要退出mysql执行：

sudo mysql_upgrade -uroot -p
