Redis3集群无限等待集群加入 [英] Redis3 cluster infinite waiting for the cluster to join

问题描述

我有 2 个服务器和 3 个 redis3 实例.我有一个 cluster-nodes 目录，其中包含每个实例的所有数据.在这里.

I have 2 servers and 3 instances of redis3 in each of them. I have a cluster-nodes directory, where I have all the data of each instance. Here it is.

cluster-nodes/
|-- 7777
|   |-- db01
|   |  -- nodes-7777.conf
|   -- redis.conf
|-- 7778
|   |-- db02
|   |   -- nodes-7778.conf
|   -- redis.conf
-- 7779
    |-- db03
    |   -- nodes-7779.conf
    -- redis.conf

这是我在7777目录下的配置文件redis.conf

Here is my config file redis.conf under the 7777 directory

pidfile /var/run/redis/redis-7777.pid
port 7777
dir /opt/redis/cluster-nodes/7777/db01/
cluster-enabled yes
cluster-config-file nodes-7777.conf
cluster-node-timeout 15000

当我尝试启动 redis 时，我得到

When I try to start redis I get

这是第一台服务器上集群节点的输出

Here is the output from cluster nodes on the first server

这是第二个

好像都是以高手开始的吧?我的配置有问题吗?谢谢.

It seems that all of them are started as masters? Is there something wrong in my configs? Thank you.

附言当我尝试相同的配置并在一台服务器上启动所有实例时，一切正常.

p.s. when I try the same configs and start all instances in one server, everything works fine.

推荐答案

就我而言，问题是我使用本地主机地址启动服务，

The problem in my case was that I was starting the service with localhost address,

./redis-trib.rb create --replicas 1 127.0.0.1:7777 127.0.0.1:7778 127.0.0.1:7779 192.168.56.41:7777 192.168.56.41:7778 192.168.56.41:7779

为了修复127.0.0.1应该被本地节点的ip地址替换，即

In order to fix that 127.0.0.1 should be substituted with ip address of the local node, i.e.

./redis-trib.rb create --replicas 1 192.168.56.40:7777 192.168.56.40:7778 192.168.56.40:7779 192.168.56.41:7777 192.168.56.41:7778 192.168.56.41:7779
