Redis

MAC下用redis图形客户端查数据库太不顺畅，刷新也不方便，偶尔说不定还来一次假死

最新验证一个东西，数据并没有做持久化，不到一分钟就会清除，如果redis进行了更新，客户端刷新等半天说不定刷新好了数据都消失了，十分不便，因此还是用连接redis-server然后进行CLI操作比较方便

首先连上redis，这几个参数即可

 
lihui@2018  ~  redis-cli --help
redis-cli 4.0.10

Usage: redis-cli [OPTIONS] [cmd [arg [arg ...]]]
  -h       Server hostname (default: 127.0.0.1).
  -p           Server port (default: 6379).
  -s         Server socket (overrides hostname and port).
  -a       Password to use when connecting to the server.

要注意的是，-a密码要带引号

如果存储的是最简单的STRING:Value，通过get可以直接得到value

通过help可以查看相关参数

 
redis-cli> help get

  GET key
  summary: Get the value of a key
  since: 1.0.0
  group: string

redis-cli>
redis-cli> get lbsmesh:data:customer_track:950300179:9
"\x01\x00com.caocao.mesh.server.manage.bo.CustomerTrackB\xcf\x04bi\xfacustomerN\xefla\xf4ln\xe7\x02\x01\x12\x00\x06\x01\xa6\xb8\xa3\x8a\a\x00\t\x01@>5v}'\xd2~\x00\t\x01@^\x0e\x00\x8d\x15\x9e(\x00"

直接可以得到value

如果在客户端上看到有多层级目录，没关系，命名空间名称最后都会带到key里面

比如set数据

 
redis-cli> help SMEMBERS

  SMEMBERS key
  summary: Get all the members in a set
  since: 1.0.0
  group: set

redis-cli>
redis-cli> SMEMBERS featureSetKey
 1) "userTime2"
 2) "model"
 3) "useTime4"
 4) "useTime3"
 5) "limitedTimes"

还有一个zset类型，在KV的基础上，加了一个score字段，按这个字段进行排序来储存

查询命令

 
redis-cli> help zrange

  ZRANGE key start stop [WITHSCORES]
  summary: Return a range of members in a sorted set, by index
  since: 1.2.0
  group: sorted_set

redis-cli>
redis-cli> ZRANGE lbs:trace:9997816224 0 5
1) "{\"accuracy\":36.0,\"cityCode\":\"0571\",\"createTime\":1532662022739,\"direction\":75.0,\"driverNo\":\"482904\",\"height\":10.0,\"lg\":120.222249,\"lt\":30.207443,\"speed\":27.0}"
2) "{\"accuracy\":35.0,\"cityCode\":\"0571\",\"createTime\":1532662032753,\"direction\":75.0,\"driverNo\":\"482904\",\"height\":10.0,\"lg\":120.223249,\"lt\":30.208843,\"speed\":17.0}"
3) "{\"accuracy\":36.0,\"cityCode\":\"0571\",\"createTime\":1532662042751,\"direction\":75.0,\"driverNo\":\"482904\",\"height\":10.0,\"lg\":120.223449,\"lt\":30.209243,\"speed\":44.0}"

5) "{\"accuracy\":38.0,\"cityCode\":\"0571\",\"createTime\":1532662062753,\"direction\":75.0,\"driverNo\":\"482904\",\"height\":10.0,\"lg\":120.225649,\"lt\":30.211643,\"speed\":21.0}"
6) "{\"accuracy\":34.0,\"cityCode\":\"0571\",\"createTime\":1532662072743,\"direction\":75.0,\"driverNo\":\"482904\",\"height\":10.0,\"lg\":120.226649,\"lt\":30.212443,\"speed\":44.0}"

hash表

 
redis-cli> help hget

  HGET key field
  summary: Get the value of a hash field
  since: 2.0.0
  group: hash

redis-cli> HGET order_dispatch_count 50001728
"2"

详细各种数据类型的增删改查CLI操作，可以参考这里Redis CLI
