Linux Nginx 还是比较常用的，于是我研究了一下Linux Nginx ，在这里拿出来和大家分享一下，希望对大家有用。Linux 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的服务器，无法用来测试，所以打算找下Linux 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
配置Linux 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]
Linux Nginx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Linux Nginx，访问 http://sp.imichat.com/可看到请求被发送到3台服务器。
Linux Nginx抓http包可看到request为
- GET / HTTP/1.1
- Host: sp.imichat.com
