Redis cluster creating cannot connect to the server, what's wrong?
<p>I have 3 different servers deployed on Aliyun, each of them is running 2 redis instances with port 6379 and 6380.</p>

<p>I was trying to build a redis cluster with these 6 nodes.(Redis version 3.2.0). But it failed and said "Sorry, cannot connect to the node 10.161.94.215:6379" (10.161.94.215 is  the lan ip address of my first server.)</p>

<p>While obviously the servers were running quite well, and I could get it by redis-cli.</p>

<p>Gem is installed.</p>

<p>Requirepass is banned, no auth is needed.</p>

<p>No ip bind </p>

<p>No protected-mode as well.</p>

<p>All the configuration options about cluster are well set.</p>

<p>What's wrong with this?</p>
