connection pdo php Report an error Solution connect

本文实例讲述了php pdo_mysql连接报错Connection failed: SQLSTATE[HY000] [2002] No such file or directory问题的解决方法。分享给大家供大家参考。具体方法如下:

错误描述:

Connection failed: SQLSTATE[HY000] [2002] No such file or directory

环境概述:
MacOS
xampp 搭建的开发环境 apache mysql php
xampp 已支持mysql oracle 测试ok,且 phpinfo已上显示支持pdo_mysql pdo_pgsql pdo_sqlite

其中mysql我用的是brew包管理安装到机器里面的,而非xampp自带的mysql

php pdo 连接报错 Connection failed: SQLSTATE[HY000] [2002] No such file or directory

开始以为找不到文件是因为 url rewrite导致的,(因为从nginx切换到apache)结果跟踪程序发现是 new pdo 报错

经过搜索一些资料研究发现:

这个是php.ini配置文件中pdo_mysql.default_socket指定的mysql.sock路径不对
我的mysql.sock文件在 /private/tmp/mysql.sock

所以要设置:

复制代码 代码如下:
pdo_mysql.default_socket=/private/tmp/mysql.sock

如果不知道自己的mysql.sock在哪里可以搜索(因为编译安装,和yum、apt-get、或者brew等包管理工具安装的位置不一样)
sudo find / -name 'mysql.sock'
下面是官方给出bug修复

1. Open up php.ini (mine was in /private/etc/)
2. locate this line: pdo_mysql.default_socket=/var/mysql/mysql.sock
3. Change the line to: pdo_mysql.default_socket=/tmp/mysql.sock
4. Restart apache

1、我这里需要补充下,如果是新系统或者刚玩php的同志,在Mac的系统中php.ini 文件不存在。
2、需要在/private/etc/目录下cp  php.ini.default
php.ini ,然后再做修改下
3、但是如果使用的xampp mysql作为数据库,那么就不需要使用官方的step2,直接写下面方式就可以了。

复制代码 代码如下:
pdo_mysql.default_socket=/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock

 
解决方法三:
复制代码 代码如下:
sudo vim /etc/php.ini

把以下三个原来空白的值都设置为:
复制代码 代码如下:
/tmp/mysql.sock
mysql.default_socket = /tmp/mysql.sock
pdo_mysql.default_socket= /tmp/mysql.sock
mysqli.default_socket =/tmp/mysql.sock

 
都修改了
修改完成后使用
复制代码 代码如下:
sudo /usr/sbin/apachectl restart

问题搞定!

希望本文所述对大家的PHP程序设计有所帮助。

The FastCGI module starts the PHP process to process requests to improve performance and stability. 3. In actual applications, you need to pay attention to configuration details, error debugging and performance optimization.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.
