  • Tomcat cluster方案共享session配置成功,yeah....

    后继版本:https://www.cnblogs.com/xiandedanteng/p/12143112.html

    参考网文:

    1.Tomcat官方文档

    2.https://blog.51cto.com/ckl893/1893848

    我的环境:

    Win10,Nginxnginx-1.16.1,tomcat9.0.30

    采用一个Nginx带两个Tomcat的方案

    Nginx的配置就是简单的负载均衡,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;
    
        access_log  logs/access.log;
    
        sendfile        on;
    
        keepalive_timeout  65;
        
        upstream tomcat{
            server localhost:8080;
            server localhost:8088;
        }
    
        server {
            listen       80;
            server_name  localhost;
            client_max_body_size 1024m;
            
            location / {
                proxy_pass http://tomcat;
                proxy_set_header Host $host:$server_port;
            }
            
    
            error_page   500 502 503 504  /50x.html;
            location = /50x.html {
                root   html;
            }
       }  
    
    }

    Tomcat1的Serverl.XML,注意Receiver的address要写自己机器的IP地址。不能写auto或是回环地址127.0.0.1,两个tomcat同在一台机器把端口错开就好:
