关于在osx中配置php访问mysql的问题

其实在osx系统下是支持apache和php的，但是自己安装mysql之后，用php的mysql_connect去连接mysql的时候，经常会出现这样的错误：

No such file or directory

这种情况大多数是因为php中配置的mysql.sock路径和mysql自己真实的mysql.sock路径不一致造成的

我们在命令行mysql之后进入mysql，然后status可以看到我们mysql的真实mysql.sock路径

someoneMacBook-Pro:apache2 someone$ mysql

从上面可以看到我们的mysql.sock地址，然后再看看我们php去哪里找mysql.sock了呢？

查看/private/etc/php.ini

这里很多人找不到php.ini这个文件，没关系，这个目录有一个php.ini.default文件，我们cp php.ini.default php.ini就可以copy一份出来

然后我们编辑这份php.ini文件，找到下面三项：

pdo_mysql.default_socket =

mysql.default_socket =

mysqli.default_socket =

也许这里你看到的都是空项，没关系，我们这里把他们全部换成 /tmp/mysql.sock 然后重启apache ： apachectl restart

之后我们的php就可以正常使用mysql_connect连接我们的mysql数据库了~~
