1、准备两个Tomcat
首先在Linux机器上部署两个Tomcat，端口分别为80和8080
2、分别部署测试应用
在两个tomcat下分别部署同一个应用testapp，很简单，就是在页面显示当前系统时间：
testapp
--WEB-INF
--web.xml
--index.jsp
index.jsp内容：
<html> <body> <center>Now time is :<%=new java.util.Date() %></center> </body> </html>
3、启动两个Tomcat
查看是否能正常运行
4、修改nginx配置
1）配置监控端口
server { listen 8080; ......}2）配置服务器集群
upstream testapp { #服务器集群名字 server 120.78.144.82:8080 weight=2; server 120.78.144.82:80 weight=1;}3)配置URL匹配路径
location /testapp { proxy_pass http://testapp; proxy_redirect default; add_header 'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Credentials' 'true'; add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent, X-Requested-With,If-Modified-Since,Cache-Control,Content-Type'; }------------------------------------------------------------
5、修改配置后重启nginx
[root@iZwz95a6wosz6klzf7o6hcZ sbin]# pwd/usr/local/nginx/sbin[root@iZwz95a6wosz6klzf7o6hcZ sbin]# ./nginx -s reload6、测试
关闭8080端口的Tomcat，如果仍能访问到testapp页面，则nginx配置成功。
