1. nginx使用80端口,所有对服务器80端口的访问都被nginx拦截。例:

127.0.0.1 www.jthinking.com
127.0.0.1 admin.jthinking.com
127.0.0.1 resource.jthinking.com

2. 在nginx的nginx.conf配置文件中增加配置。例:

----------------------------------------------------

#前台服务器,当访问域名为www.jthinking.com时,转去访问本机的60060端口,增加一个tomcat服务器监听此端口

server {
    listen       80;
    server_name  www.jthinking.com;
    #charset koi8-r;
    #access_log  logs/host.access.log  main;

    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    location / {
        proxy_pass http://127.0.0.1:60060;
        proxy_connect_timeout 600;
        proxy_read_timeout 600;
    }
}


#后台服务器,当访问域名为admin.jthinking.com时,转去访问本机的60061端口,增加一个tomcat服务器监听此端口

server {
    listen       80;
    server_name  admin.jthinking.com;
    #charset koi8-r;
    #access_log  logs/host.access.log  main;

    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    location / {
        proxy_pass http://127.0.0.1:60061;
        proxy_connect_timeout 600;
        proxy_read_timeout 600;
    }
}

#静态资源服务器,当访问域名为resource.test.com下的静态资源时,nginx直接将资源返回,无需通过tomcat,效率高

server {
    listen       80;
    server_name  resource.jthinking.com;
    #charset koi8-r;
    #access_log  logs/host.access.log  main;

    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    location / {
        root /root/Website/Resource;
    }
}

----------------------------------------------------


3. 修改Tomcat服务器配置server.xml

修改三处端口(每台主机的端口号的范围为0到65535)例:

第一个Tomcat:

<Server port="60050" shutdown="SHUTDOWN">
<Connector port="60060" protocol="HTTP/1.1" />
<Connector port="60070" protocol="AJP/1.3" />

第二个Tomcat:

<Server port="60051" shutdown="SHUTDOWN">
<Connector port="60061" protocol="HTTP/1.1" />
<Connector port="60071" protocol="AJP/1.3" />

......

在同一台主机上的每个Tomcat的每个端口都不允许重复。
