+### Q24. 多个FE，在使用Nginx实现web UI负载均衡的时候，登录不进去的情况
+
+Doris 可以部署多个FE，在访问Web UI的时候，如果使用Nginx进行负载均衡，因为Session问题会出现不停的提示要重新登录，这个问题其实是Session共享的问题，Nginx提供了集中Session共享的解决方案，这里我们使用的是nginx中的ip_hash技术，ip_hash能够将某个ip的请求定向到同一台后端，这样一来这个ip下的某个客户端和某个后端就能建立起稳固的session，ip_hash是在upstream配置中定义的：
+
+```
+upstream doris.com {
+ server 172.22.197.238:8030 weight=3;
+ server 172.22.197.239:8030 weight=4;
+ server 172.22.197.240:8030 weight=4;
+ ip_hash;
