redis 命令

一、链接 redis

[hladmin@localhost redis-5.0.8]$ ./src/redis-cli -p 6377 --raw -
127.0.0.1:6377> auth XXXXXX
OK
127.0.0.1:6377>

二、链接集群

[hladmin@localhost cluster]$ ../src/redis-cli -c -p 7001 --raw -a 'xxxxxx' 

三、查看集群节点

127.0.0.1:7001> cluster nodes
210b4b0add06938447a5f4507a35dc368e57dd69 127.0.0.1:7005@17005 slave cece6270da76cae25b3d8e0d80b103ab2dcad6e5 0 1641275946559 5 connected

127.0.0.1:7001> 

四、查看集群信息

127.0.0.1:7001> cluster info
cluster_state:ok
cluster_slots_assigned:16384
cluster_slots_ok:16384
cluster_slots_pfail:0
cluster_slots_fail:0
cluster_known_nodes:6
cluster_size:3
cluster_current_epoch:6
cluster_my_epoch:1
cluster_stats_messages_ping_sent:17785
cluster_stats_messages_pong_sent:17714
cluster_stats_messages_sent:35499
cluster_stats_messages_ping_received:17709
cluster_stats_messages_pong_received:17785
cluster_stats_messages_meet_received:5
cluster_stats_messages_received:35499
127.0.0.1:7001> 

 

五、切换到一号数据库、并查看数据库大小

127.0.0.1:6377> SELECT 1
OK
127.0.0.1:6377[1]> DBSIZE
(integer) 9
127.0.0.1:6377[1]> 

数据库为9条记录

六、查看所有数据

127.0.0.1:6377[1]> KEYS *
1) "100001|^*-|000008"
2) "144624|^*-|shipinhuiyi"
3) "300001|^*-|300001"
4) "100001|^*-|100001"
5) "100001|^*-|zi001001"
6) "119190|^*-|290001"
7) "144624|^*-|20001615"
8) "300001|^*-|300001001"
9) "100001|^*-|zi001"
127.0.0.1:6377[1]> 

七、查看指定key的数据类型

127.0.0.1:6377[1]> type 100001|^*-|000008
set
127.0.0.1:6377[1]> 

八、查看指定集合成员数

127.0.0.1:6377[1]> SCARD 100001|^*-|000008
(integer) 1
127.0.0.1:6377[1]>

九、查看指定集合成员

127.0.0.1:6377[1]> SMEMBERS 100001|^*-|000008
1) "B174A1690D9876552A137F70CABEEC11"
127.0.0.1:6377[1]> 

 十、查看hash表字段数量（用于缓存数据库记录列表）

127.0.0.1:7001> type QXT:SCH:1
hash
127.0.0.1:7001> HLEN QXT:SCH:1
(integer) 1

十一、查看hash表字段列表

127.0.0.1:7001> hkeys QXT:SCH:1
1) "n1"

十二、查看hash表指定字段值

127.0.0.1:7001> HGET QXT:SCH:1 n1
"{\"nodeName\":\"n1\",\"sendSpeed\":0,\"checkTime\":\"01-04 11:36:00\",\"succLinks\":2,\"links\":[{\"linkState\":\"0\",\"linkId\":\"565FF7C174701E4B0E00A2ECE4AE14E0\",\"linkStateDesc\":\"\xe6\x88\x90\xe5\x8a\x9f\"},{\"linkState\":\"0\",\"linkId\":\"3F75F1EB8628F3157608514787838B35\",\"linkStateDesc\":\"\xe6\x88\x90\xe5\x8a\x9f\"}],\"failLinks\":0,\"state\":\"1\",\"channelId\":\"1\"}"
127.0.0.1:7001> 

127.0.0.1:7001> hget qxt.location.cache 1837897
{"sectionno":"1837897","provinceId":31,"oper":0,"province":"广西","createtime":"2020-07-20 02:03:18"}
127.0.0.1:7001>
