php - 返回警告错误

Question

http://go.wlg.co.nz/login.php

我的页面运行良好，我发誓我没有更改任何内容。现在它返回这个:

Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/content/93/10501493/html/go/connect.php on line 15

Warning: mysql_select_db() expects parameter 2 to be resource, boolean given in /home/content/93/10501493/html/go/connect.php on line 16

Warning: mysql_real_escape_string() expects parameter 2 to be resource, boolean given in /home/content/93/10501493/html/go/login.php on line 16

Warning: mysql_real_escape_string() expects parameter 2 to be resource, boolean given in /home/content/93/10501493/html/go/login.php on line 17

Warning: mysql_close() expects parameter 1 to be resource, boolean given in /home/content/93/10501493/html/go/connect.php on line 18

有什么明显的东西跳出来吗？

Answer 1

确保mysql服务正在运行

service mysqld start

或者

您正在连接到“localhost”还是“127.0.0.1”？当您连接到“localhost”时，将使用套接字连接器，但是当您连接到“127.0.0.1”时，将使用 TCP/IP 连接器。你可以如果套接字连接器未启用/工作，请尝试使用“127.0.0.1”。
