• 关于redis里的db

  进入客户端，默认使用编号为0的数据库，可以通过命令切换，如：

  lch@localhost:Desktop $ redis-cli
  redis 127.0.0.1:6379> select 1
  OK
  redis 127.0.0.1:6379[1]> select 0
  OK
  redis 127.0.0.1:6379>
  

• 设置一对key-value

  redis 127.0.0.1:6379> set name luchanghong
  OK
  redis 127.0.0.1:6379> set gender male
  OK
  redis 127.0.0.1:6379> set age 24
  OK
  

• 匹配查找key

  redis 127.0.0.1:6379> keys *
  1) "age"
  2) "gender"
  3) "name"
  redis 127.0.0.1:6379> keys name
  1) "name"
  redis 127.0.0.1:6379> keys nam
  (empty list or set)
  redis 127.0.0.1:6379> keys nam*
  1) "name"

  redis 127.0.0.1:6379> get gender
  "male"
  redis 127.0.0.1:6379> get age
  "24"

  redis 127.0.0.1:6379> exists name
  (integer) 1
  redis 127.0.0.1:6379> exists names
  (integer) 0
  

• 删除key

  redis 127.0.0.1:6379> set test1 1

  redis 127.0.0.1:6379> set test2 2
  OK
  redis 127.0.0.1:6379> del test1
  (integer) 1
  redis 127.0.0.1:6379> exists test1
  (integer) 0
  redis 127.0.0.1:6379> exists test2
  (integer) 1
