提示:ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'mysql'。 前两天也出现过这个问题,网上找了一个比较流行的方法(见方法一),搞定了。今天又用这个试了试,却搞不定,在网上找了半天,终于发现是因为mysql数据库的user表里

提示:ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'mysql'。

前两天也出现过这个问题,网上找了一个比较流行的方法(见方法一),搞定了。今天又用这个试了试,却搞不定,在网上找了半天,终于发现是因为mysql数据库的user表里,存在用户名为空的账户即匿名账户,导致登录的时候是虽然用的是root,但实际是匿名登录的,通过错误提示里的''@'localhost'可以看出来,于是解决办法见方法二。


方法一:
1.关闭mysql
# service mysqld stop
2.屏蔽权限
# mysqld_safe --skip-grant-table
屏幕出现: Starting demo from .....
3.新开起一个终端输入
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;//记得要这句话,否则如果关闭先前的终端,又会出现原来的错误
mysql> \q

方法二:
1.关闭mysql
# service mysqld stop
2.屏蔽权限
# mysqld_safe --skip-grant-table
屏幕出现: Starting demo from .....
3.新开起一个终端输入
# mysql -u root mysql
mysql> delete from user where USER='';
mysql> FLUSH PRIVILEGES;//记得要这句话,否则如果关闭先前的终端,又会出现原来的错误
mysql> \q
