Nginx Tomcat 負載均衡搭建 靜態文件分離

本文主要講解Nginx作爲前端web服務器，tomcat作爲後端應用服務器，所有外網請求從nginx轉到內網tomcat處理，也就是nginx將請求反向代理到tomcat，或者說是nginx+tomcat的負載均衡。nginx版本1.9.12，tomcat版本7.0.4.2

負載均衡nginx配置以及靜態文件分離

upstream tomcat_cluster {
	server 127.0.0.1:8080 weight=1 max_fails=2 fail_timeout=30s;
	server 127.0.0.1:8081 weight=1 max_fails=2 fail_timeout=30s;
}

server {
    listen 80;
    server_name  www.yddsj.com;
    index index.jsp index.html index.htm;
	
    #發佈目錄 /www/yddsj
    root  /www/yddsj;
     
    location /
    {
		# tomcat_cluster必須和upstream的名稱一樣
		proxy_pass http://tomcat_cluster;
		proxy_next_upstream http_502 http_504 error timeout invalid_header;
		proxy_set_header   REMOTE-HOST $remote_addr;
		proxy_set_header   Host $host;
		proxy_set_header   X-Real-IP $remote_addr;
		proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
		client_max_body_size   100m; 
		#expires定義用戶瀏覽器緩存的時間爲10天
		expires 10d;
    }

	#配置Nginx動靜分離則加入以下的配置
	location ~* \.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css|swf|flv|wma|wmv|asf|mp3|mmf|zip|rar)$
	{
		root /www/yddsj;		
		expires 10d;
	}
 
}
