Nginx代理与反向代理（rpm包安装）

注意：

情况1：当后端是独立的php-fpm服务器模块的话需要fastcgi协议情况2：当后端是LAMP的话，使用的就是Apache协议不需要开启fastcgi模块直接写个location / {proxy_pass http://backservers;}即可 此次实验安装的Nginx中fastcgi_params不适用此次，所以需要更该：fastcgi_params模块内容：fastcgi_param GATEWAY_INTERFACE CGI/1.1;fastcgi_param SERVER_SOFTWARE nginx;fastcgi_param QUERY_STRING $query_string;fastcgi_param REQUEST_METHOD $request_method;fastcgi_param CONTENT_TYPE $content_type;fastcgi_param CONTENT_LENGTH $content_length;fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;fastcgi_param SCRIPT_NAME $fastcgi_script_name;fastcgi_param REQUEST_URI $request_uri;fastcgi_param DOCUMENT_URI $document_uri;fastcgi_param DOCUMENT_ROOT $document_root;fastcgi_param SERVER_PROTOCOL $server_protocol;fastcgi_param REMOTE_ADDR $remote_addr;fastcgi_param REMOTE_PORT $remote_port;fastcgi_param SERVER_ADDR $server_addr;fastcgi_param SERVER_PORT $server_port;fastcgi_param SERVER_NAME $server_name;

测试MySQL连通性：<?php$conn = mysql_connect('127.0.0.1','root','');if ($conn)echo succ;elseecho fail;mysql_close();?>使用的是Apache协议：

location /up/ {proxy_pass http://cwy/;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;}
