mysql> USE mysql; -- 切换到 mysql DB Database changed mysql> SELECT User, Password, Host FROM user; -- 查看现有用户,密码及允许连接的主机 +------+----------+-----------+ | User | Password | Host | +------+----------+-----------+ | root | | localhost | +------+----------+-----------+ row in set (0.00 sec) mysql> -- 只有一个默认的 root 用户, 密码为空, 只允许 localhost 连接 mysql> -- 下面我们另外添加一个新的 root 用户, 密码为空, 只允许 192.168.1.100 连接 mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.100' IDENTIFIED BY '' WITH GRANT OPTION; mysql> -- @'192.168.1.100'可以替换为@‘%’就可任意ip访问，当然我们也可以直接用 UPDATE 更新 root 用户 Host, 但不推荐, SQL如下: mysql> -- UPDATE user SET Host='192.168.1.100' WHERE User='root' AND Host='localhost' LIMIT 1; mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) |
