Redis 集群:CLUSTERDOWN The cluster is down

1.錯誤

(error)CLUSTERDOWN The cluster is down

2.問題表現

    Java項目使用redis集群時報錯,

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

    查看redis集群啟動情況: ps -ef | grep "redis",如圖

    在操作redis集群寫入數據時報錯:

(error)CLUSTERDOWN The cluster is down

3.解決辦法

    3-1進入redis安裝目錄

cd /opt/redis-3.0.1/src

    3-2修復集群節點,如7000,需要修復全部集群節點

./redis-trib.rb fix 127.0.0.1:7000

     3-3測試

redis-cli -c -p 7000
set test ok
