在PHP中设置默认MySQL套接字,pdo_mysql.default_socket PHP 5.3

我在设置 MySQL的默认PDO套接字位置时遇到问题,而没有通过将PDO类初始化为变量来实现.我试过改变mysql.default_socket变量.但没有喜悦.目前唯一有效的方法是通过类DSN实例化.

如您所见,我已经更改了php.ini文件中的默认套接字设置,但是当我尝试连接到MySQL时,我仍然在PDO中收到套接字错误.它让我相信PDO驱动程序没有使用php.ini中的设置.我确信有一些配置PDO的方法,但我的php.ini中没有任何内容.是否应该在php.ini中设置PDO,或者它们是否包含在其他地方？

pdo_mysql.default_socket

你试过设置这个ini值吗？请参考http://php.net/manual/de/ref.pdo-mysql.php

使用以下配置选项在编译期间也可以影响该值：

--with-mysql-sock=/my/path/mysql.sock

更新：我发现问题是已知的PHP bug.

第一：当使用127.0.0.1作为db主机而不是localhost时,可以解决该问题. PHP将以这种方式通过TCP套接字连接.

要更改位置,您必须从具有特殊配置选项的源编译PHP.我成功地使用以下(基本)命令行更改了mysql套接字的位置：

./configure 
  --with-mysql 
  --with-mysqli=mysqlnd 
  --enable-pdo 
  --with-pdo-mysql=mysqlnd 
  --with-mysql-sock=/home/mysql/mysqld.sock

 make
 make install

最后的伎俩结合了最后两个. –with-mysql-sock = file设置.sock文件的位置,但只有在–with-pdo-mysql =设置为mysqlnd(mysql本机驱动程序)时才使用它.如果缺少此选项,pdo将与系统中的libmysqlclient链接.因此,您还可以重新编译libmysqlclient(使用已修改的套接字路径)并保持php不变.

注意：这只是使PHP使用PDO的基本配置.如果您需要其他扩展(如json,xml等),则需要其他配置选项.如果以这种方式执行(原始发行版)版本,您将找到Linux发行版用于编译PHP的配置：php -i.
