如:MySQL 连接远程数据库(192.168.5.116),端口“3306”,用户名为“root”,密码“123456”
如:MySQL 连接本地数据库,用户名为“root”,
Enter password:
在localhost登入mysql后,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,将"localhost"改称"%"
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
例如: 你想myuser使用mypassword(密码)从任何主机连接到mysql服务器的话。
mysql>GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器,并使用mypassword作为密码
mysql>GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3'IDENTIFIED BY
'mypassword' WITH GRANT OPTION;
mysql>FLUSH PRIVILEGES
使修改生效,就可以了
1、在采用法二授权法之后,无法在本地登录mysql(如:#mysql -u root -p -h 192.168.5.116
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'loadb116' (using password: YES)
上例中loadb116是主机名.
解决方法:
1、这时可以使用:mysql -u root -p 登录,进入到mysql后。
mysql> grant all privileges on *.* to 'root'@'loadb116'
identified by '123456' with grant option;
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
2、在本地使用ip地址登录
# mysql -u root -p -h 192.168.5.116
Enter password:
