Redis集群平均分配hash slots

一、查看当前槽位状态

[root@mgm57 ~]# redis-trib.rb  info  192.168.88.56:6379  槽不平均
192.168.88.53:6379 (f2c1bdb7...) -> 1 keys | 4096 slots | 1 slaves.
192.168.88.51:6379 (0eb3b7aa...) -> 3 keys | 8192 slots | 1 slaves.
192.168.88.52:6379 (a9cb8ccd...) -> 2 keys | 4096 slots | 1 slaves.
[OK] 6 keys in 3 masters.
0.00 keys per slot on average.

二、执行平均分配：

# 平均分配hash slots
[root@mgm57 ~]# redis-trib.rb rebalance 192.168.88.56:6379

三、再次查看是否平均

[root@mgm57 ~]# redis-trib.rb info 192.168.88.56:6379
192.168.88.53:6379 (f2c1bdb7...) -> 2 keys | 5462 slots | 1 slaves.
192.168.88.51:6379 (0eb3b7aa...) -> 2 keys | 5461 slots | 1 slaves.
192.168.88.52:6379 (a9cb8ccd...) -> 2 keys | 5461 slots | 1 slaves.
[OK] 6 keys in 3 masters.
0.00 keys per slot on average.
