nginx?反向代理負(fù)載均衡?tomcat集群應(yīng)用

環(huán)境介紹：
系統(tǒng)：centos5.8_64
192.168.0.201：nginx服務(wù)器
192.168.0.202：tomcat服務(wù)器
192.168.0.203：tomcat服務(wù)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(fù)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(cè)試和運(yùn)行

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

如果顯示下面信息，即表示配置沒(méi)問(wèn)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(yùn)行nginx服務(wù)

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

?

查看nginx進(jìn)程

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

如果顯以類似下面的信息，即表示nginx已經(jīng)啟動(dòng)

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

4：另外兩臺(tái)tomcat服務(wù)器安裝請(qǐng)看這里
http://www.yunwei8.com/tomcat/

5：測(cè)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(guān)閉其中一臺(tái)tomcat服務(wù)器
http://192.168.0.201/index.jsp
如果還是可以正常訪問(wèn)說(shuō)明架設(shè)成功
