   集群Node名称：luster-config-file nodes_7006.conf
   集群超时时间：cluster-node-timeout 5000
   

   

3. 创建集群

   1.启动redis服务
   redis-server /home/redis/workspace/cluster_one/redis_7001.conf
   redis-server /home/redis/workspace/cluster_one/redis_7002.conf
   redis-server /home/redis/workspace/cluster_one/redis_7003.conf
   redis-server /home/redis/workspace/cluster_one/redis_7004.conf
   redis-server /home/redis/workspace/cluster_one/redis_7005.conf
   redis-server /home/redis/workspace/cluster_one/redis_7006.conf
    
   2.创建集群
   redis-cli -a 123456 --cluster create --cluster-replicas 1 192.168.1.4:7001 192.168.1.4:7002 192.168.1.4:7003 192.168.1.4:7004 192.168.1.4:7005 192.168.1.4:7006
   注意：前3个为主节点，后3个为从节点，创建命令只执行一次，重启集群只需要重启redis服务
   

   

4. 启动集群

   redis-server /home/redis/workspace/cluster_one/redis_7001.conf
   redis-server /home/redis/workspace/cluster_one/redis_7002.conf
   redis-server /home/redis/workspace/cluster_one/redis_7003.conf
   redis-server /home/redis/workspace/cluster_one/redis_7004.conf
   redis-server /home/redis/workspace/cluster_one/redis_7005.conf
   redis-server /home/redis/workspace/cluster_one/redis_7006.conf
   

   

5. 关闭集群

   1.方式一:redis-cli命令关闭集群（推荐）
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7001 shutdown
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7002 shutdown
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7003 shutdown
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7004 shutdown
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7005 shutdown
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7006 shutdown
    
   2.方式二:根据进程号关闭集群（方便）
   ps -ef | grep -i redis
   kill -9 102629 102631 102637 102643 102649 102694
   

   
   

6. 登录集群

   1.登录集群不同的客户端
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7001
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7002
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7003
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7004
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7005
   redis-cli -a 123456 -c -h 192.168.1.4 -p 7006
    
   2.客户端切换时需要先退出：quit
   

   

   

7. 集群信息
   

8. 数据备份、恢复
