异常:java.sql.SQLException: Access denied for user ‘root‘@‘RJB-Z‘ (using passwrod)。
String url ="jdbc:mysql://192.168.1.169:3306/test“;
密码没错的,在命令行窗口都能登进去。上网查了下发现是因为root用户不允许远程连接,
我在这个网站(http://xucons.javaeye.com/blog/278581)找到了解决方法:改表或者赋权。http://xucons.javaeye.com/blog/278581
如果你连接mysql的时候发生这个错误:
Sql代码
ERROR 1130: Host ‘192.168.1.3‘ is not allowed to connect to this MySQL server
[sql] view plaincopy
以下是引用内容:
ERROR 1130: Host ‘192.168.1.3‘ is not allowed to connect to this MySQL server
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"%"
Java代码
mysql -u root -p
mysql>use mysql;
mysql>update user set host = ‘%‘ where user = ‘root‘;
mysql>select host, user from user;
[java] view plaincopy
mysql -u root -p
mysql>use mysql;
mysql>update user set host = ‘%‘ where user = ‘root‘;
mysql>select host, user from user;
[java] view plaincopy
[java] view plaincopy
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。
Sql代码
GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘%‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;
[sql] view plaincopy
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
Sql代码
GRANT ALL PRIVILEGES ON *.* TO ‘myuser‘@‘192.168.1.3‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;
本人使用的是第二种方法。
MysqL的root用户不允许远程连接
