查看Redis集群信息

guodong@sh-guodong src % redis-cli -p 7001 cluster nodes

5e94ae9b31b2029b2e881e9e302800941e1debcd 127.0.0.1:7004@17004 slave 5500c4ce07bbb0b9f0d10ade053a423fd319afa6 0 1648971894002 2 connected

查看Redis进程

guodong@sh-guodong src % ps -ef|grep redis              

  501 72133     1   0 11:21上午 ??         1:10.82 redis-server 127.0.0.1:7001 [cluster] 
  501 72389     1   0 11:21上午 ??         1:10.31 redis-server 127.0.0.1:7002 [cluster] 
  501 72594     1   0 11:21上午 ??         1:10.66 redis-server 127.0.0.1:7003 [cluster] 
  501 72891     1   0 11:22上午 ??         1:10.31 redis-server 127.0.0.1:7004 [cluster] 
  501 73095     1   0 11:22上午 ??         1:10.83 redis-server 127.0.0.1:7005 [cluster] 
  501 73216     1   0 11:22上午 ??         1:09.53 redis-server 127.0.0.1:7006 [cluster] 
  501 16500 93357   0  3:45下午 ttys001    0:00.00 grep redis

杀死进程Redis-server3的进程

guodong@sh-guodong src % kill -9 72594

再次查看Redis进程信息

guodong@sh-guodong src % ps -ef|grep redis

  501 72133     1   0 11:21上午 ??         1:10.91 redis-server 127.0.0.1:7001 [cluster] 
  501 72389     1   0 11:21上午 ??         1:10.40 redis-server 127.0.0.1:7002 [cluster] 
  501 72891     1   0 11:22上午 ??         1:10.41 redis-server 127.0.0.1:7004 [cluster] 
  501 73095     1   0 11:22上午 ??         1:10.93 redis-server 127.0.0.1:7005 [cluster] 
  501 73216     1   0 11:22上午 ??         1:09.62 redis-server 127.0.0.1:7006 [cluster] 
  501 16690 93357   0  3:45下午 ttys001    0:00.00 grep redis

再次查看Redis集群信息，总结：可能要等一会儿Redis4才能成为master节点

guodong@sh-guodong src % redis-cli -p 7001 cluster nodes
