Nginx 添加 PHP 支持

1. 背景介绍
   默认安装的Nginx是无法打开php文件的，需要修改相关配置才能支持php
2. 安装
   yum -y install epel-release 
   yum -y install nginx 
   yum install php php-mysql php-fpm
   vi /etc/php.ini
   修改cgi.fix_pathinfo=0
   sed -i "s/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/g" /etc/php.ini
   vi /etc/php-fpm.d/www.conf
   追加一条Listen参数：
   listen = /var/run/php-fpm/php-fpm.sock
   service php-fpm restart
   chkconfig php-fpm on
3. 修改Nginx虚拟主机文件，使其支持php
   location ~ \.php$ {
   try_files $uri =404;
   fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
   fastcgi_index index.php;
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
   include fastcgi_params;
   }
   重启nginx服务
   service nginx restart
