nginx配置集群

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。
