1. 把redis集群中的 master 节点信息记录在文件 redis_object_port.info 中, 方便下一步遍历各实例中的大 keys

redis-cli -h 10.240.47.147 -p 7000 cluster nodes | grep master | awk '{print $2}' | awk -F ':' '{print " -h " $1 " -p " $2}'  > redis_object_port.info

redis集群 测试 redis集群查询key_redis集群

 

2. 遍历各个实例中的大keys ( 参数 -i  0.1, 表示每隔100条scan指令就休眠0.1s, 这样redis的ops就不会剧烈抬高,但是扫描时间会变长)

more redis_object_port.info | while read object; do redis-cli $object --bigkeys -i 0.1  ; done > redis_object_bigkey.result
