Redis-cluster 进程和网络连接不一致问题

[fsckzy]

创建了 redis 集群，7003、7004、7005 三个节点。 查看网络连接为什么会出现 6 个节点？

[root@iZ1mlxtcx2Z ~]# netstat -tpln |grep redis

哨兵吧

[fsckzy]

@cloverstd 哨兵的进程应该是 xx.xx.xx.xx:17003[Sentinel]

[kemad]

你这个是 tcp 端口侦听，不是进程。看 netstat 输出的最后一列，前面的数字才是 pid，只有三个进程。

本人对 redis 不熟。

3 进程，6 个监听。无毛病啊

[zts1993]

redis cluster : redis 端口+10000 作为集群通信端口

结贴吧

[yexiangyang]

搭车 问一句 client list 里面怎么总是多一个客户端链接

[fsckzy]

@zts1993 谢谢

昨天也恰好看到了，https://redis.io/topics/cluster-tutorial

> Every Redis Cluster node requires two TCP connections open. The normal Redis TCP port used to serve clients, for example 6379, plus the port obtained by adding 10000 to the data port, so 16379 in the example.

@yexiangyang
cmd=info 估计服务器上是有 redis 运行状态的监控吧
