Redis 集群:CLUSTERDOWN The cluster is down

1.错误

(error)CLUSTERDOWN The cluster is down

2.问题表现

    Java项目使用redis集群时报错,

HTTP Status 500 - Could not get a resource from the pool

    查看redis集群启动情况: ps -ef | grep "redis",如图

    在操作redis集群写入数据时报错:

(error)CLUSTERDOWN The cluster is down

3.解决办法

    3-1进入redis安装目录

cd /opt/redis-3.0.1/src

    3-2修复集群节点,如7000,需要修复全部集群节点

./redis-trib.rb fix 127.0.0.1:7000

     3-3测试

redis-cli -c -p 7000
set test ok
