Tomcat 后端服务器实现 Session ID会话保持
基础架构:
7-6 代理服务器nginx配置
7-3 tomcat 服务器
7-5 同理
测试:
此时刷新,会话ID一直在变,这样不好
如何解决呢?
不好的是确定ip之后,会一直在一台机上,不调度了
但是这样不调度又不好了
我们在tomcat添加以下配置,实现sessionID不变,却依旧可以调度
官网文档:Apache Tomcat 9 (9.0.87) - Clustering/Session Replication How-To

7-3
再改一处
也是在官方文档里面
7-5
测试:
IP地址在变,但此时的sessionID不变
