在向大家详细介绍CentOS Nginx之前,首先让大家了解下CentOS Nginx,然后全面介绍CentOS Nginx,希望对大家有用。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。
由于项目目前只有一台CentOS Nginx 的服务器,无法用来测试,所以打算找下Nginx windows下版本;http://www.kevinworthington.com/nginx/win32/以上为win32的版本用户访问 sp.imichat.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CentOS Nginx
配置CentOS Nginx 的nginx.conf
-
http {}增加如下内容
-
upstream sp.imichat.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 sp.imichat.com;
-
#charset koi8-r;
-
#access_log logs/host_access_log main;
-
-
location / {
-
proxy_pass http://sp.imichat.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/sp.imichat.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://sp.imichat.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
-
Host: sp.imichat.com
