13:strlen key Key The length of the value

14:mset K1 v1 K2 v2 Bulk set multiple key values

15:getbit key Offset bit operation

16:setbit Key offset value sets the binary value at the specified position

17:hset car Prince Hset command is a hash command indicating that the key to be created is a hash type

Similar to HashMap car in Java is the HASHMAP variable name Prince is the key of HashMap

18:hget car Prince similar to get hash value

19:hgetall car gets all the values of the hash based on car

20:hexists key fields are used to determine whether a field exists

21:hsetnx key field value does not exist for values execution. The value does not execute when it exists.

22:hincrby car Prince 100 to Prince plus 100

23:hdel key field Deletes a key

24:hkeys Key Gets the name of all fields

25:hvals key Gets the value of all fields

26:lpush key value adds an element to the left of the list, and the return value indicates the length of the list after the element is added

27:rpush key value to add an element to the right of the list, the return value indicates the length of the list after adding the element

28:lpop key pops the element from the left side of the list.

29:rpop key pops the element from the right side of the list.

30:llen Key gets the number of elements in the list. When key does not exist, it returns 0;

31:lrange Key start stop returns the element in the list. Element is returned from the following table, start to stop

32:lrem Key Count value deletes the specified number of elements for value

33:lindex key index based on subscript index visit list

34:lset key index value to modify the values of the list subscript index

35:ltrim Key start end deletes an element other than the specified index

36:linsert key Before|after value1 value2 to the list value is value1 before or after inserting a value of value2

37:rpoplpush List 1 List 2 Move the element from the right side of List 1 to the list 2

38:sadd key member[member ...] adds one or more elements to the collection. Do not join if the element already exists (the collection is the actual set set based on the Hashtable implementation)

39:srem Key member Delete member

40:smembers key gets the elements in the collection

41:sismember Key member determines whether the element member is in the collection

42:sdiff key [Key ...] Set of differences between sets

43:sinter key [key ...] computes the intersection between multiple collections

44:sunion key [Key ...] performs a set operation on multiple collections

45:scard key to get the number of elements in the collection

46:sdiffstore destination key [key ...] perform a set operation and store the result

47:sinterstore key [key ...] computes the intersection between multiple collections and stores the results

48:sunionstore key [Key ...] performs a set operation on multiple sets and stores the result

49:srandmember key [Count] is used to randomly fetch elements from the collection

50:spop key pops an element from the collection

51:zadd key score member added to the ordered collection

52:zscore key member gets the fraction of the element member

53:zrange key start end [with scores] gets ranked the results returned by some returned elements the size of the photo scores is arranged from small to large (start end refers to subscript)

54:zrevrange key start end [with scores] is the opposite of the result of the Zrange command. Results the size of the installation scores is arranged from large to small

55:zrangebyscore Key min Max [with scores] [limit offset count] takes the value of the fraction between Min max. different from Zrange. Zrange the value of the subscript between the start end

The 56:save command saves the current snapshot. will block other processes

The 57:BGSAVW command is also a save snapshot, which is saved through the background of the child process.

The 58:info command is used to view information about the Redis database.

59:monitor Monitoring of all redis command execution status
