redis命令行查询某个key值

使用工具xshell连接到按照redis的linux服务器，然后执行以下命令：

[root@dbserver 10:28 ~ ]$ redis-cli

127.0.0.1:6379> help

redis-cli 5.0.2

To get help about Redis commands type:

"help @<group>" to get a list of commands in <group>

"help <command>" for help on <command>

"help <tab>" to get a list of possible help topics

"quit" to exit

To set redis-cli preferences:

":set hints" enable online hints

":set nohints" disable online hints

Set your preferences in ~/.redisclirc

127.0.0.1:6379> keys *

(empty list or set)

127.0.0.1:6379> quit

[root@dbserver 10:29 ~ ]$ redis-cli -p 1001

127.0.0.1:1001> keys *

1) "TEST.BUSINESSINFO.60906"

2) "TEST.BUSINESSINFO.60724"

3) "TEST.BUSINESSINFO.61506"

[root@dbserver 11:12 ~ ]$ redis-cli -h 127.0.0.1 -p 7001 keys "*DATA*"

redis-cli: 该命令可以连接上redis默认的端口6379所开放的实例

keys * ：keys 通配符，根据所需要查找的key替换通配符即可查到你想要查找的key信息

redis-cli -h 实际ip -p 端口 keys "*通配符*"：在指定端口实例下，通过关键字（通配符）查询所需要的key信息。
