There are two redis server. And I have run three redis instances on each server.
When I executed cluster meet [ip] [port] to add the cluster nodes, I found I just could add the nods which was running on the same server. Everytime I run this command, it alwasys echo an "OK" for me. But when I use cluster nodes to check the nodes list, it always shows like this.
172.18.0.155:7010> cluster meet 172.18.0.156 7020
OK
172.18.0.155:7010> cluster nodes

You can see the nodes status is disconnected. And you can find it will disappare from the list, if you check again about 5s later.
Has anybody meet this problem before? I have no idea how to solve this problem. Please help me. Thanks a lot.
I have solved the problem. I found I had done some mistakes with the bind configuration. When I just add one IP which communicate with other nodes for the bind setting. The cluster nodes can add normally.
