  • Nginx tomcat 集群负载均衡解决笔记

    1. Windows

    下载nginx 地址:http://nginx.org/   本文章使用的版本为1.5.1

    下载完后解压,在conf目录修改nginx.conf我的配置如下:

    #user  nobody;
    worker_processes  1;
    
    #error_log  logs/error.log;
    #error_log  logs/error.log  notice;
    #error_log  logs/error.log  info;
    
    #pid        logs/nginx.pid;
    
    
    events {
        worker_connections  1024;
    }
    
    
    http {
        include       mime.types;
        default_type  application/octet-stream;
    
        #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
        #                  '$status $body_bytes_sent "$http_referer" '
        #                  '"$http_user_agent" "$http_x_forwarded_for"';
    
        #access_log  logs/access.log  main;
        
        client_header_timeout  3m;  
        client_body_timeout    3m;  
        send_timeout           3m;  
       
        client_header_buffer_size    1k;  
        large_client_header_buffers  4 4k;  
    
        sendfile        on;
        tcp_nopush      on;  
        tcp_nodelay     on;
        #tcp_nopush     on;
        
    
        #keepalive_timeout  0;
        keepalive_timeout  65;
    
        #gzip  on;

       upstream localhost {
        #根据ip计算将请求分配各那个后端tomcat,许多人误认为可以解决session问题,其实并不能。
        #同一机器在多网情况下,路由切换,ip可能不同
        #ip_hash;
        server localhost:9097 weight=1;
        server localhost:9098 weight=1;
        server localhost:9097 backup;
        server localhost:9098 backup;
        #jvm_route $cookie_JSESSIONID|sessionid reverse; #session复制的配置
        ip_hash;
        }

    
         
        upstream backend {
            server localhost:9097;
            server localhost:9098;
        }
    
        server {
            listen       9096;
            server_name  localhost;
    
            #charset koi8-r;
    
            #access_log  logs/host.access.log  main;
    
            location ~ ^/(WEB-INF)/ {  
                deny all;  
            }  
      
            ###所以的静态文件人gif、jpg等都在本地打开,存放的目录为html,保存时间为30天  
            location ~ .*.(gif|jpg|jpeg|png|bmp|swf|css|js|htm|html)$ {

        #}
    
    }

    下载Tomcat

    修改端口为9097

    另一个修改为9098

    分别启动二个tomcat和nginx在地址栏中输入http://locahost/则可以看到tomcat欢迎界面了

    Linux 和window配置基本一样,只有linux下tomcat的配置要注意,需要添加环境变量
