nginx.conf 配置文件详解

简单的实现nginx在前端做反向代理服务器的例子，处理js、png等静态文件，jsp等动态请求转发到其它服务器tomcat：

user  www www;

worker_processes  ;

error_log  logs/error.log;

#error_log  logs/error.log  notice;

#error_log  logs/error.log  info;

pid        logs/nginx.pid;

events {

    use epoll;

    worker_connections  ;

}

http {

    include       mime.types;

    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

    #                  '$status $body_bytes_sent "$http_referer" '

    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;

    # tcp_nopush     on;

    keepalive_timeout  ;

  # gzip压缩功能设置

    gzip on;

    gzip_min_length 1k;

    gzip_buffers     16k;

    gzip_http_version 1.0;

    gzip_comp_level ;

    gzip_types text/html text/plain text/css text/javascript application/json application/javascript application/x-javascript application/xml;

    gzip_vary on;

  # http_proxy 设置

    client_max_body_size   10m;

    client_body_buffer_size   128k;

    proxy_connect_timeout   ;

    proxy_send_timeout   ;

    proxy_read_timeout   ;

    proxy_buffer_size   4k;

    proxy_buffers    32k;

    proxy_busy_buffers_size   64k;

    proxy_temp_file_write_size  64k;

    proxy_temp_path   /usr/local/nginx/proxy_temp  ;

  # 设定负载均衡后台服务器列表

    upstream  backend  {

              #ip_hash;

              server   192.168.10.100: max_fails= fail_timeout=30s ;

              server   192.168.10.101: max_fails= fail_timeout=30s ;

    }

  # 很重要的虚拟主机配置

    server {

        listen       ;

        server_name  itoatest.example.com;

        root   /apps/oaapp;

        charset utf-;

        access_log  logs/host.access.log  main;

        #对 / 所有做负载均衡+反向代理

        location / {

            root   /apps/oaapp;

            index  index.jsp index.html index.htm;

            proxy_pass        http://backend;

            proxy_redirect off;

            # 后端的Web服务器可以通过X-Forwarded-For获取用户真实IP

            proxy_set_header  Host  $host;

            proxy_set_header  X-Real-IP  $remote_addr;

            proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;

            proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;

        }

        #静态文件，nginx自己处理，不去backend请求tomcat

        location  ~* /download/ {

            root /apps/oa/fs;  

        }

        location ~ .*\.(gif|jpg|jpeg|bmp|png|ico|txt|js|css)$

        {

            root /apps/oaapp;

            expires      7d;

        }

           location /nginx_status {

            stub_status on;

            access_log off;

            allow 192.168.10.0/;

            deny all;

        }

        location ~ ^/(WEB-INF)/ {

            deny all;

        }

        #error_page                /.html;

        # redirect server error pages to the static page /50x.html

        #

        error_page        /50x.html;

        location = /50x.html {

            root   html;

        }

    }

  ## 其它虚拟主机，server 指令开始

}
