nginx反向代理tomcat应用

1、修改hosts文件，解析DNS

  127.0.0.1 nexus.seven7.org	
   127.0.0.1 bbs.seven7.org
   127.0.0.1 wiki.seven7.org

2、nginx.conf

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    upstream  bbs.seven7.org {
        server 127.0.0.1:8080 weight=9 max_fails=0;
        #server 127.0.0.1:8082 backup;
        
    }
    
    upstream  wiki.seven7.org {
        server 127.0.0.1:8080 weight=9 max_fails=0;

    }
   
    include       mime.types;
    default_type  application/octet-stream;
    client_max_body_size 10m;
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

    server {
        listen       80;
        server_name   bbs.seven7.org;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        location / {
            root   html;
            index  index.html index.htm index.jsp;
            proxy_pass http://bbs.seven7.org;
            proxy_redirect    off;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $http_host;
       }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
    
    server {
        listen       80;
        server_name   wiki.seven7.org;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        location / {
            root   html;
            index  index.html index.htm index.jsp;
            proxy_pass http://wiki.seven7.org;
            proxy_redirect    off;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $http_host;
       }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
    
     server {
        listen       80;
        server_name   nexus.seven7.org;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        location / {
            root   html;
            index  index.html index.htm index.jsp;
            proxy_pass http://nexus.seven7.org;
            proxy_redirect    off;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Host $http_host;
       }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

3、在tomcat的server.xml中增加host

 <Host name="bbs.seven7.org"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
					<Context path="" docBase="D:/workspace/j2ee/apache-tomcat-6.0.20/webapps/bbs" debug="0"></Context>
      </Host>
      <Host name="wiki.seven7.org"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
					<Context path="" docBase="D:/workspace/j2ee/apache-tomcat-6.0.20/webapps/wiki" debug="0"></Context>
      </Host>

这时候就可以通过域名访问应用了
