(SOS)centos7, nginx无法解析php文件

一、问题描述

当访问 *.php文件时，没有显示文件的内容而是直接下载了所要访问的文件，如index.php。但是访问index.html却正常，翻看了网上所有遇到这个问题的帖子，依然没有找到解决方案，所以发帖求救。

二、问题思路

• 1.nginx和php-fpm进程都已经起来，监听的端口都是对的.

[root@~]# ps -ef |grep nginx
root      1045     1  0 09:40 ?        00:00:00 nginx: master process /usr/sbin/nginx
www-data  1049  1045  0 09:40 ?        00:00:00 nginx: worker process
root      2695  2675  0 10:21 pts/1    00:00:00 grep --color=auto nginx
[root@~]# ps -ef |grep php-fpm
root       697     1  0 09:40 ?        00:00:00 php-fpm: master process (/etc/php-fpm.conf)
www-data  1010   697  0 09:40 ?        00:00:00 php-fpm: pool www
www-data  1011   697  0 09:40 ?        00:00:00 php-fpm: pool www
www-data  1022   697  0 09:40 ?        00:00:00 php-fpm: pool www
www-data  1023   697  0 09:40 ?        00:00:00 php-fpm: pool www
www-data  1024   697  0 09:40 ?        00:00:00 php-fpm: pool www
root      2698  2675  0 10:22 pts/1    00:00:00 grep --color=auto php-fpm
[root@~]# netstat -tunlp|grep 9000
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      697/php-fpm: master 

• 2.查看nginx.cnf的配置如下.网上主要都是关于fastcgi_param这个参数的，尝试过三种写法，都没有生效。

        location / {
	    root html;
            index index.html index.htm index.php;
        }

	location ~ \.php$ {
             #root /usr/share/nginx/html; 
             root html;
             fastcgi_pass 127.0.0.1:9000;
             fastcgi_index index.php;
             #fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html/$fastcgi_script_name;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             #fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
             include fastcgi_params;
          }

[root@~]# ls  /usr/share/nginx/html/
404.html  50x.html  index.html  index.php  
nginx-logo.png  poweredby.png  wordpress  wordpress-4.9.4-zh_CN.tar.gz

• 3.查看php-fpm的log日志似乎也没有不正常的地方

[root@~]# tail -f /var/log/php-fpm/error.log 
[03-Nov-2018 00:00:43] NOTICE: Terminating ...
[03-Nov-2018 00:00:43] NOTICE: exiting, bye-bye!

[03-Nov-2018 09:40:36] NOTICE: Terminating ...
[03-Nov-2018 09:40:36] NOTICE: exiting, bye-bye!
[03-Nov-2018 09:40:52] NOTICE: fpm is running, pid 697
[03-Nov-2018 09:40:52] NOTICE: ready to handle connections
[03-Nov-2018 09:40:52] NOTICE: systemd monitor interval set to 10000ms

• 4.nginx和php-fdm的用户名我都设置了www-data

[root@~]# cat /etc/nginx/nginx.conf
# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

#user nginx;
user www-data;

[root@~]# cat /etc/php-fpm.d/www.conf |grep www-data
user = www-data
group = www-data

三、SOS求救

网上看了很多帖子，基本上就是是就修改nginx.cnf就可以了。但是我试了所有的方法都没有用。在centos7中，默认的html路径是 /usr/share/nginx/html/ .感觉还是nginx没有调用php-fpm模块导致的，但是始终没有什么思路，求大神解答？？？
