nginx?反向代理負載均衡?tomcat集群應用

環境介紹：
系統：centos5.8_64
192.168.0.201：nginx服務器
192.168.0.202：tomcat服務器
192.168.0.203：tomcat服務器

1：安裝Nginx不在詳解
看這里http://www.yunwei8.com/nginx124/

2：配置nginx

#??rm?-rf?/usr/local/server/nginx/conf/nginx.conf

#??vi?/usr/local/server/nginx/conf/nginx.conf

復制以下代碼粘貼

user??www?www;
worker_processes??8;
error_log??/web/logs/nginx_error.log??crit;
pid?logs/nginx.pid;?
events?
{?
????use?epoll;?
????worker_connections?65535;?
}

3：測試和運行

#??/usr/local/server/nginx/sbin/nginx?-t

如果顯示下面信息，即表示配置沒問題

nginx:?the?configuration?file?/opt/nginx/conf/nginx.conf?syntax?is?ok
nginx:?configuration?file?/opt/nginx/conf/nginx.conf?test?is?successful

輸入代碼運行nginx服務

#??/usr/local/server/nginx/sbin/nginx

?

查看nginx進程

#??ps?aux|grep?[n]ginx

如果顯以類似下面的信息，即表示nginx已經啟動

root?????22900??0.0??0.1??43216??1576??????????Ss???08:23???0:00?nginx:?master?process?/usr/local/server/nginx/sbin/nginx

www??????23026??0.0??2.6??68816?26828??????????S????08:48???0:00?nginx:?worker?process??

4：另外兩臺tomcat服務器安裝請看這里
http://www.yunwei8.com/tomcat/

5：測試反向代理及tomcat集群是否正常
http://192.168.0.201
http://192.168.0.201/index.jsp

關閉其中一臺tomcat服務器
http://192.168.0.201/index.jsp
如果還是可以正常訪問說明架設成功
