连接代码:

$this->linkid = @mysql_pconnect($host, $user, $password) or die(mysql_error());
Copy after login

Make a phpinfo() page.  Look for 'mysql.default_socket', 'mysqli.default_socket',and'pdo_mysql.default_socket'.  Remember their value; this is where PHP is trying to connect to MySQL.

解决办法:1.首先确定是mysql_connect()和mysql_pconnect()的问题,故障现象就是函数返回空,而mysql_error()返回"No such file or directory"。

2.写个phpinfo页面,找到mysql.default_socket、mysqli.default_socket、pdo_mysql.default_socket。

3.启动mysql,执行命令 STATUS; 记下UNIX socket的值。

4.如果2和3的值不一样,则打开php.ini(可以从phpinfo页面中找到php.ini的位置,默认是/private/etc/php.ini),将2中提到的三个配置项的值改成3的值。

5.重启apache。
