1.报错前配置，云服务器一台，使用Nginx负载两个Tomcat服务（同一IP不同端口8080、8081）。配置两个Tomcat的context.xml前项目正常可访问，配置后添加了Redis做共享的Valve  Manager 后报错，如下

<Valve className="tomcat.request.session.redis.SessionHandlerValve" />

<Manager className="tomcat.request.session.redis.SessionManager" 

host="49.233.153.118" 

port="6379"

password="123456" 

database="0"

maxInactiveInterval="7200" 

/>

希望有解决方案的告知一下，非常感谢
