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：

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：
