检查集群

redis-cli -c -a passwdxxx -h 10.10.10.50 -p 7001 cluster nodes
redis-cli -c -a passwdxxx -h 10.10.10.50 -p 7001 admin_config get maxclients
redis-cli -c -a passwdxxx -h 10.10.10.50 -p 7001 --cluster check 10.10.10.49:7002

集群登录：

/usr/local/redis/src/redis-cli -a passwdxxx -h 172.16.17.80 -p 8002 -c

加入集群：

redis-cli -a passwdxxx --cluster create 10.10.10.48:7001 10.10.10.49:7001 10.10.10.50:7001 10.10.10.48:7002 10.10.10.49:7002 10.10.10.50:7002 --cluster-replicas 1

新增节点：

/usr/local/redis/bin/redis-cli  -a xxxxxxxxxxxxxxxxx -p 7001 --cluster add-node  10.10.12.149:7002  10.10.12.151:7001  --cluster-slave

剔除节点：

redis-cli --cluster del-node 10.10.10.48:7001 f24b935a50a788692479c6beaf7c556f6d082253

检查集装状态：

/usr/local/redis/src/redis-cli -c -h10.10.10.48:7002 -p 8001 -a passwdxxx --cluster check 172.16.17.80:8002

布隆过滤器

  yum install git
 cd /data
 git clone https://github.com/RedisBloom/RedisBloom.git
 cd RedisBloom
 make
 echo "loadmodule /data/RedisBloom/redisbloom.so" >>/data/redis7001/redis7001.conf
