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 reload
6、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。
