配置如下：

[root@localhost ~]$ cat /usr/local/nginx/conf/vhost/test.com.conf 
server {
    listen 80;
    server_name www.test.com;
    index index.html index.html index.php;
    root /data/www;

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name;
    }
} 

# 关于 fastcgi_pass 配置，
[root@localhost ~]$ /usr/local/nginx/sbin/nginx -t            
[root@localhost ~]$ /usr/local/nginx/sbin/nginx -s reload

创建 php 文件：

[root@localhost ~]$ cat /data/www/1.php
<?php
phpinfo();
?>

测试是否解析：

[root@localhost ~]$ curl -x 127.0.0.1:80 http://www.test.com/1.php    # 没有解析到PHP的输出情况
<?php
phpinfo();
?>
[root@localhost ~]$ curl -x 127.0.0.1:80 http://www.test.com/1.php    # 解析到PHP的输出情况
