從新啓動redis集羣時啓動失敗，報錯：

查看redis集羣狀態：
發現集羣狀態是正常的！！！！！！！java
解決方法：
關閉防火牆！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！
systemctl stop firewalld
若是集羣狀態是fail
先嚐試：
./redis-cli -c -p 6380 127.0.0.1:6380> flushall OK 127.0.0.1:6380> cluster reset OK 127.0.0.1:6380> exit
# 建立集羣 /sxt/app/redis-3.0.6/src/redis-trib.rb create --replicas 1 172.18.25.174:6380 172.18.25.174:6381 172.18.25.174:6382 172.18.25.174:6383 172.18.25.174:6384 172.18.25.174:6385
仍是不行的話
1)、將須要新增的節點下rdb等本地備份文件刪除；同時將新Node的集羣配置文件刪除,即：刪除你redis.conf裏面cluster-config-file所在的文件；node
cd /opt/redis rm -rf ./data/*
--》
2)、再次添加新節點若是仍是報錯，則登陸新Node,./redis-cli–h x –p對數據庫進行清除：web
127.0.0.1:6381> flushdb #清空當前數據庫
3)、建立redis集羣
/sxt/app/redis-3.0.6/src/redis-trib.rb create --replicas 1 172.18.25.174:6380 172.18.25.174:6381 172.18.25.174:6382 172.18.25.174:6383 172.18.25.174:6384 172.18.25.174:6385
