我創建了一個Redis羣集作爲波紋管。Redis羣集 - 從站不FAILOVER
xxx.xxx.xxx.195:9100 xxx.xxx.xxx.196:9100 xxx.xxx.xxx.197:9100
xxx.xxx.xxx.195:9200 xxx.xxx.xxx.196:9200 xxx.xxx.xxx.197:9200
我已經經歷集羣失敗且無法修復的時候我停止2個Redis的實例,其是集羣的主站(xxx.xxx.xxx.196的2個實例)在同一時間,
xxx.xxx.xxx.195:9100 (Master) xxx.xxx.xxx.196:9100 (Master) xxx.xxx.xxx.197:9100 (Slave)
xxx.xxx.xxx.195:9200 (Slave) xxx.xxx.xxx.196:9200 (Master) xxx.xxx.xxx.197:9200 (Slave)
但同時如果我停止.195服務器的兩個實例,其中9100 -Master
和9200 - Slave
。集羣恢復並正常工作
羣集配置文件:
protected-mode no
activerehashing yes
cluster-enabled yes
cluster-config-file /opt/redis/conf/nodes9100.conf
cluster-slave-validity-factor 0
cluster-node-timeout 5000
appendonly yes
Redis的記錄在專用從屬服務器:
