Nginx反向代理配置

Nginx配置反向代理笔记


1、介绍,有两台机器,一个是nginx服务器(192.168.0.82),另外一个是tomcat服务器跑项目(192.168.0.80)

    **************************************************************************************************

    正向代理。代理客户端(多个客户端通过nginx访问服务器,对服务器来说,访问的客户端只有明确的nginx.在此,nginx代理了客户端)

    反向代理。代理服务器(一个客户端访问nginx,但是客户端不知道提供服务的到底是哪台机器,在此nginx充当了代理服务器的角色)。

   反向代理中负载均衡用到的几种方法(weight轮询问,ip_hash,url_hash,fair(智能动态分配))。

2、配置,

user www www;
worker_processes 1; #设置值和CPU核心数一致
error_log /usr/local/nginx/logs/nginx_error.log crit; #日志位置和日志级别
pid /usr/local/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 65535;
events
{
  use epoll; 
  worker_connections 65535;
}
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';
  
  #charset gb2312;
     
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;

  client_max_body_size 8m;
     
  sendfile on;
  tcp_nopush on;
  keepalive_timeout 60;

  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;

  gzip on;

  gzip_comp_level 2;
  gzip_types text/plain application/x-javascript text/css application/xml;
  gzip_vary on;
 
  #limit_zone crawler $binary_remote_addr 10m;
 #下面是server虚拟主机的配置

 upstream test
   {
     server 192.168.0.80:8080;  
   }
 server
  {
    listen 80;#监听端口
    server_name localhost;#域名
    index index.html index.htm index.php;
    root /usr/local/nginx/html;#站点目录
    location /
    {proxy_pass http://test; #test指的是上面upstream test中的test.可以用别的名字,在这个location下面配置反向代理,也可以配置到别的文件,用include引用
    proxy_set_header Host $host;  #在这个location下面配置反向代理,也可以配置到别的文件,用include引用到http{}.
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Cookie $http_cookie;
    }    

      location ~ .*\.(php|php5)?$
    {
      #fastcgi_pass unix:/tmp/php-cgi.sock;
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      include fastcgi.conf;
    }
    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|ico)$
    {
      expires 30d;
  # access_log off;
    }
    location ~ .*\.(js|css)?$
    {
      expires 15d;
   # access_log off;
    }
    access_log off;
  }

}
