tomcat+nginx+域名绑定+servlet

nginx同时是一个很强的反向代理server，可以用来跟tomcat做负载均衡集群，而且配置很简单，不过有个需要注意的地方：目前nginx跟后端server使用http1.0协议，不能keepalive，只能每次重新打开连接。需要关闭后端的keepalive，否则会产生大量后端的timewait状态的socket连接。
主要的是nginx的配置

<!-- lang: shell -->
server {
  listen          80;
  server_name     YOUR_DOMAIN;
  root            /PATH/TO/YOUR/WEB/APPLICATION;
  location / {
    index index.jsp;
  }
  location ~ \.do$ {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }                                                                                                       
  location ~ \.jsp$ {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }
  location ^~/servlets/* {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }
}
