lnmp环境搭建好后,,,,解析php文件报错 502

注:(nginx本身不能处理PHP，它只是个web服务器，当接收到请求后，如果是php请求，则发给php解释器处理，并把结果返回给客户端。
nginx一般是把请求发fastcgi管理进程处理，fascgi管理进程选择cgi子进程处理结果并返回被nginx
PHP-FPM其实是PHP源代码的一个补丁，旨在将FastCGI进程管理整合进PHP包中。必须将它patch到你的PHP源代码中，在编译安装PHP后才可以使用。)

测试服务器相关目录:

root目录: /var/www/html info.php

php.ini php-fpm 目录:
/etc/php/7.0/fpm
/etc/php/7.0/fpm/pool.d 下的 www.conf
php-fpm进程:
/run/php/php7.0-fpm.pid

问题1:404错误

2017/06/12 11:20:10 [alert] 63567#63567: 768 worker_connections are not enough

2017/06/12 11:20:10 [error] 63567#63567: *2296 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: www.hsx.com, request: "GET /info.php HTTP/1.0", upstream: "http://127.0.0.1:80/info.php", host: "127.0.0.1"

2017/06/12 11:20:10 [error] 63567#63567: *2296 open() "/usr/share/nginx/html/50x.html" failed (2: No such file or directory), client: 127.0.0.1, server: www.hsx.com, request: "GET /info.php HTTP/1.0", upstream: "http://127.0.0.1:80/info.php", host: "127.0.0.1"

原因未配置hosts文件

问题2: nginx不解析php文件:

2017/06/12 13:50:35 [error] 65057#65057: *18 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /hxs.php HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost"

解决给www.conf(php-fpm)中的

listen = /run/php/php7.0-fpm.sock 后添加 listen = 9000

然后重启php-fpm /etc/init.d/php/php-fpm.conf restart

问题3: No input file specified. 修改nginx.conf配置

fastcgi_param     SCRIPT_FILENAME   /scripts$fastcgi_script_name;
