【README】

最近搭建一個redis集群，參考博文 （https://www.cnblogs.com/mafly/p/redis_cluster.html） 對集群配置后，master， slave 也啟動起來，但無法插入數據；

?

【1】報錯信息；

[root@centos201 redis-cluster]# /usr/local/bin/redis-cli -c -h 192.168.163.201 -p 6379 192.168.163.201:6379> keys * 1) "k3" 2) "k2" 192.168.163.201:6379> set k4 v4 (error) CLUSTERDOWN The cluster is down

【2】解決方法

step1） 找到創建集群的 文件 redis-trib.rb 并執行如下命令檢車集群服務（ip+端口號）

[root@centos201 bin]# ./redis-trib.rb check 192.168.163.201:6379 Connecting to node 192.168.163.201:6379: OK Connecting to node 192.168.163.201:6381: OK Connecting to node 192.168.163.202:6380: OK Connecting to node 192.168.163.202:6381: OK Connecting to node 192.168.163.201:6380: OK Connecting to node 192.168.163.202:6379: OK *** WARNING: 192.168.163.202:6381 claims to be slave of unknown node ID e3f10671246e54c0ae60b7bf9f73efc9c60a2669. >>> Performing Cluster Check (using node 192.168.163.201:6379) M: 3faa9492e958d4f7d4e882d0c478d5445e3eafa8 192.168.163.201:6379slots:0-5460 (5461 slots) master1 additional replica(s) S: fb2d63eef5286da9613ff252ea3e02bc5bf1714a 192.168.163.201:6381slots: (0 slots) slavereplicates ec6f04c5cb3e3392b7787445440b7494ddff8923 S: 2f71a7878b1ea9a773bc0c2b938a97b72fe99883 192.168.163.202:6380slots: (0 slots) slavereplicates 3faa9492e958d4f7d4e882d0c478d5445e3eafa8 S: 5a3d443feba5c67451b31ded6480bb5a70804b88 192.168.163.202:6381slots: (0 slots) slavereplicates e3f10671246e54c0ae60b7bf9f73efc9c60a2669 S: e2d2d0554c6051bb27b51aa5093ae66a85c4a16c 192.168.163.201:6380slots: (0 slots) slavereplicates ec6f04c5cb3e3392b7787445440b7494ddff8923 M: ec6f04c5cb3e3392b7787445440b7494ddff8923 192.168.163.202:6379slots:5461-10922 (5462 slots) master2 additional replica(s) [OK] All nodes agree about slots configuration. >>> Check for open slots... >>> Check slots coverage...
