php - 问题：PHP致命错误：无法通过套接字连接到本地MySQL服务器

Question

我在运行我的 php 代码时遇到问题（有时它运行成功，但我需要将来如何避免它）错误显示为：

PHP Fatal error:  Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /home/myegyme/public_html/Connections/myegy.php on line 9

“ /home/myegyme/public_html/Connections/myegy.php ”包含：

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_myegy = "localhost";
$database_myegy = "mydatabase";
$username_myegy = "myusername";
$password_myegy = "mypassword";
$myegy = mysql_pconnect($hostname_myegy, $username_myegy, $password_myegy) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

我怎么解决这个问题？。请帮我 ！

Answer 2

I had that problem once, when the socket was already in use (another program or database). Maybe that is the case, if you say that it runs sometimes.

Answer 3

将单词“localhost”更改为“127.0.0.1”，您的 mysql 将不再尝试连接到套接字，而是通过 TCP/IP。
