一、连接Redis服务器

redis-cli -h host -p port -a password

 

二、查询所有的keys

keys *

 

 

三、获取指定的key对应的值

1）查询key对应的value 

type <key>

2）不同的type，查询的命令不一样

if value is of type string -> GET <key>
if value is of type hash -> HGETALL <key>
if value is of type lists -> lrange <key> <start> <end>
if value is of type sets -> smembers <key>
if value is of type sorted sets -> ZRANGEBYSCORE <key> <min> <max>
