6、通过cluster slot命令返回主从关系并解析结果

192.168.0.103:6379> CLUSTER slots

1) 1) (integer) 5461  ---> start slot

2) (integer) 10922 --> end slot

3) 1) "192.168.0.103" --> master ip

2) (integer) 6380 --> master port

3) "84e20cc2619b5dbc811e5974f235b1ee365c0926"

4) 1) "192.168.0.103" --> slave ip

2) (integer) 6383 --> slave port

3) "b76596f357c000f3878f0e86adeb2f1a05128879"
