各位，求助我在linux安装了mysql，建立一个用户使用的登陆方式是localhost，可在是在安装程序的时候使用localhost不能登陆，改为127.0.0.1就可请问怎么解决
谢谢

1.使用root登陆mysql
2.
mysql> select user,host,password from mysql.user;
+--------+-----------+-------------------------------------------+
| user   | host      | password                                  |
+--------+-----------+-------------------------------------------+
| root   | localhost | *5FE6B3E9169F4FBE38D17F5E7E5DF54CE5C9CFDE |
| root   | Emily     | *5FE6B3E9169F4FBE38D17F5E7E5DF54CE5C9CFDE |
| root   | 127.0.0.1 | *5FE6B3E9169F4FBE38D17F5E7E5DF54CE5C9CFDE |
| pengyi | 127.0.0.1 |                                           |
+--------+-----------+-------------------------------------------+
mysql> grant all on *.* to 'pengyi'@'localhost';
mysql> select user,host,password from user;
+--------+-----------+-------------------------------------------+
| user   | host      | password                                  |
+--------+-----------+-------------------------------------------+
| root   | localhost | *5FE6B3E9169F4FBE38D17F5E7E5DF54CE5C9CFDE |
| root   | Emily     | *5FE6B3E9169F4FBE38D17F5E7E5DF54CE5C9CFDE |
| root   | 127.0.0.1 | *5FE6B3E9169F4FBE38D17F5E7E5DF54CE5C9CFDE |
| pengyi | localhost |                                           |
| pengyi | 127.0.0.1 |                                           |
+--------+-----------+-------------------------------------------+

看看my.ini里是不是只写了
allow from 127.0.0.1
另外Linux有HOST表这类东西吗
