解决spring4连接redis集群报错：CLUSTERDOWN The cluster is down（转载）

原因是redis出错了。解决方法如下：

1、使用命令检查REDIS状态： /java/redis/redis7000/src/redis-trib.rb check 192.168.249.230:7000

[ERR] Nodes don't agree about configuration!
>>> Check for open slots...
[WARNING] Node 192.168.249.230:7001 has slots in importing state (4658).
[WARNING] The following slots are open: 4658
>>> Check slots coverage...
[OK] All 16384 slots covered.

2、使用命令修复REDIS： /java/redis/redis7000/src/redis-trib.rb fix  192.168.249.230:7001

[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.

 

通过以上两步即可解决：CLUSTERDOWN The cluster is down

若报错：

/usr/bin/env: ruby: No such file or directory

需要安装ruby的环境，这里推荐使用yum install ruby安装

yum  install ruby
