MySQL允许远程登录配置

mysql -h 10.17.11.187 -uroot -ploushang

开启远程登录步骤：

1, 登录 Mysql-Server 连接本地 mysql (默认只允许本地连接)

2, 修改 Mysql-Server 用户配置

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 |

+------+----------+-----------+

1 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

12

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)
