php使用pdo连接报错Connection failed SQLSTATE的解决方法_php技巧
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:
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。
解决方法三:
把以下三个原来空白的值都设置为:
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
问题搞定!
希望本文所述对大家的PHP程序设计有所帮助。
