nginx配置详解2-guichina的学习笔记
server#配置虚拟机
{
listen 80;
#配置监听端口
server_name image.***.com;
#配置访问域名
location ~* \.(mp3|exe)$ {
#对以“mp3或exe”结尾的地址进行负载均衡
proxy_pass http://img_relay$request_uri;
#设置被代理服务器的端口或套接字，以及URL
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#以上三行，目的是将代理服务器收到的用户的信息传到真实服务器上

注释：变量
Ngx_http_core_module模块支持内置变量，他们的名字和apache的内置变量是一致的。
首先是说明客户请求title中的行，例如$http_user_agent,$http_cookie等等。
此外还有其它的一些变量
$args此变量与请求行中的参数相等
$content_length等于请求行的“Content_Length”的值。
$content_type等同与请求头部的”Content_Type”的值
$document_root等同于当前请求的root指令指定的值
$document_uri与$uri一样
$host与请求头部中“Host”行指定的值或是request到达的server的名字（没有Host行）一样
$limit_rate允许限制的连接速率
$request_method等同于request的method，通常是“GET”或“POST”
$remote_addr客户端ip
$remote_port客户端port
$remote_user等同于用户名，由ngx_http_auth_basic_module认证
$request_filename当前请求的文件的路径名，由root或alias和URI request组合而成
$request_body_file
$request_uri含有参数的完整的初始URI
$query_string与$args一样
$sheeme http模式（http,https）尽在要求是评估例如
Rewrite ^(.+)$ $sheme://example.com$; Redirect;
$server_protocol等同于request的协议，使用“HTTP/或“HTTP/
$server_addr request到达的server的ip，一般获得此变量的值的目的是进行系统调用。为了避免系统调用，有必要在listen指令中指明ip，并使用bind参数。
$server_name请求到达的服务器名
$server_port请求到达的服务器的端口号
$uri等同于当前request中的URI，可不同于初始值，例如内部重定向时或使用index
