mysql error 1130 hy000:Host'localhost'解决方案

ERROR 1130 (HY000): Host 'localhost' is not allowed to connect to this MySQL server www.jb51.net 

出现原因: 
mysql只有一个root用户,修改root密码后选了MD5,提交后,重新 
登陆出现“Host 'localhost' is not allowed to connect to this MySQL server..." 
尝试另一个mysql库中的user表,覆盖,不行,估计是版本不同 
解决: 
编辑 my.ini 

在[mysqld]的段中加上一句:skip-grant-tables 

例如: 
Java代码 

复制代码代码如下:

[mysqld] 
datadir=/var/lib/mysql 
socket=/var/lib/mysql/mysql.sock 
skip-name-resolve 
skip-grant-tables 

目的是为了: 

跳过MySQL的访问控制,任何人都可以在控制台以管理员的身份进入MySQL数据库。 

需要注意的是在修改完密码以后要把MySQL服务器停掉重新启动才会生效 

重启mysql服务! 


mysql 配置文件目录:/etc/my.cnf

root 密码为空的时候配置文件中下面这句:

skip-grant-tables

GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY '123' WITH GRANT OPTION;

执行这句时候错误:

ERROR 1290 (HY000): The MySQL server is  running with the --skip-grant-tables option so it cannot execute this  statement
mysql> GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY '123'  WITH GRANT OPTION;
ERROR 1290 (HY000): The MySQL server is  running with the --skip-grant-tables option so it cannot execute this  statement

这个时候我们只需要

flush privileges

一下,在添加用户就OK了,

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY '123' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

这个时候我们成功搞定了,再登录就可以了。

如果报错如下信息:

Error: Cannot retrieve repository metadata (repomd.xml) for repository: InstallMedia. Please verify its path and try again
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我们只要到/etc/yum.repo.s下面把packetxxxx.repo和redhat.repo两个文件删除掉,再启动就可以了,
