CentOSNginx已经是目前公认的效率很高的代理服务,同时可以用来做负载均衡。用户访问www.server110.com均衡到10.10.10.181:8080;10.10.10.181:8081;10.10.10.181:8082这3台服务器。配置CentOSNginx的nginx.confhttp{}增加如下内
CentOS Nginx 已经是目前公认的效率很高的代理服务,同时可以用来做负载均衡。
用户访问
www.server110.com 均衡到 10.10.10.181:8080; 10.10.10.181:8081;
10.10.10.181:8082这3台服务器。
配置CentOS Nginx 的nginx.conf
http {}增加如下内容
upstream www.server110.com
{server 10.10.10.181:8080;
server 10.10.10.181:8081;
server 10.10.10.181:8082; }
server {} 修改异侠信息:
listen 80;
server_name www.server110.com;
#charset koi8-r;
#access_log logs/host_access_log main;
location / {
proxy_pass http://www.server110.com;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
access_log logs/www.server110.com.log combined;
[/code]
启动181上的3个tomcat,修改tomcat首页加入端口信息,以用来清晰看到当前分配到那台tomcat启动Nginx,访问
http://www.server110.com/可看到请求被发送到3台服务器。
抓http包可看到request为
GET / HTTP/1.1
