PHP学习之Mac下mysql_connect报No such file or directory的解决方法

结合网络上提供的解决方案提供在mac下的详细解决方案

1.找到/private/etc/php.ini文件，并打开并查看文件

.....
pdo_mysql.default_socket=
.....
mysql.default_socket =
.....
mysqli.default_socket =
.....

你会看到里面的这三个值内容为空或者有值。

2.打开终端运行mysql，输入如下命令

mysql> status

输出如下内容

--------------

复制下 UNIX socket：后面的值 /tmp/mysql.sock

然后修改第1步中找到的三个值为/tmp/mysql.sock 如下情况

.....
pdo_mysql.default_socket=/tmp/mysql.sock
.....
mysql.default_socket =/tmp/mysql.sock
.....
mysqli.default_socket =/tmp/mysql.sock
.....

然后打开终端运行如下命令，重启apache服务器

sudo apachectl restart

然后重新调试php代码就可以解决问题了！

如果还是解决不了，那应该是其他问题
