Redis-cluster 进程和网络连接不一致问题

This topic created in 2915 days ago, the information mentioned may be changed or developed.

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 tcp 0 0 192.168.201.127:17003 0.0.0.0:* LISTEN 19533/redis-server tcp 0 0 192.168.201.127:17004 0.0.0.0:* LISTEN 19537/redis-server tcp 0 0 192.168.201.127:17005 0.0.0.0:* LISTEN 19541/redis-server tcp 0 0 192.168.201.127:7003 0.0.0.0:* LISTEN 19533/redis-server tcp 0 0 192.168.201.127:7004 0.0.0.0:* LISTEN 19537/redis-server tcp 0 0 192.168.201.127:7005 0.0.0.0:* LISTEN 19541/redis-server [root@iZ1mlxtcx2Z ~]# ps -ef|grep redis root 19533 1 0 May11 ? 00:10:06 redis-server 192.168.201.127:7003 [cluster] root 19537 1 0 May11 ? 00:11:39 redis-server 192.168.201.127:7004 [cluster] root 19541 1 0 May11 ? 00:06:04 redis-server 192.168.201.127:7005 [cluster] root 29113 28971 0 09:25 pts/0 00:00:00 grep redis

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

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

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

结贴吧

搭车问一句 client list 里面怎么总是多一个客户端链接

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
