MySQL上的一个数据库要备份,装了个MySQL的gui工具。打开"MySQL Administrator"工具,填好用户名和密码却登录不了,老是报这个错“ERROR 1130: Host 'lijuan-' is not allowed to connect to this MySQL server”。网上查了下,有这两个方法解决: 解决方法:
1。 改表法。可能是你的帐号不允许从远程登陆,只能在localhost。这个时候只要在localhost的那台电脑,登入mysql后,更改 "mysql" 数据库里的 "user" 表里的 "host" 项,从"localhost"改称"%"
- mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user;
mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user;
2. 授权法。例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。
- GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器,并使用mypassword作为密码
- GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
