php pdo连接报错Connection failed: SQLSTATE[HY000] [2002]

   下面我们来看看php pdo_mysql连接报错Connection failed: SQLSTATE[HY000] [2002] No such file or directory问题的解决办法。

  错误

  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:

  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。

  pdo_mysql.default_socket=/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock

  解决方法三

  sudo vim /etc/php.ini

  把以下三个原来空白的值都设置为 /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

  sudo /usr/sbin/apachectl restart
