mysql 开放，关闭 远程授权

默认安装mysql是关闭远程连接的 这样也有助于系统的安全 但是有时候需要开启下远程连接方便操作

开启连接 mysql -uroot -p 进入mysql 输入密码

GRANT ALL PRIVILEGES ON * . * TO ‘root’@'%’ IDENTIFIED BY ‘你的mysql密码’


WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0


MAX_UPDATES_PER_HOUR 0 ;

flush privileges;

输入这两个命令即可开启mysql远程连接

关闭授权

REVOKE ALL PRIVILEGES ON *.* FROM root@”%”;
USE mysql;
DELETE FROM user WHERE User=”root” and Host=”%”;
FLUSH PRIVILEGES;

在记个命令 select host,user from user where user=”root”;
