Operation Practice of Redis NoSQL database

1, set a 1 assignment is converted to a character type by default (type a can query the variable type)
2, get a query A's value
3, Rpush list_a a b c defines a list containing a,b,c three variables list_a
4, Lpus H List_a A inserts element a
5, lrange list_a 0 9 to the left of the list list_a the first 10 elements of List_a
6, Lrange list_a 0-1 shows all elements of list_a. (-1 means the last element)
7, Lpop list_a takes the first element out and deletes it in the list, Rpop list_a is the right to take out.
8, Hmset user:01 username jimforit password [email protected] vertified 1 stores customer information in a Redis file as a hash value.
9, Hget user:01 The value of the user username of the 01 numbers in the user file.
10, Hgetall user:01 can get all key-value values of the User Object 01 number.
11, Hmset user:01 username Lixiaoteng indicates that the key value of username in the file of user object number 01 is updated to Lixiaoteng
12, Sadd L_set a b C creates a new one containing a, a, The unordered collection of C three elements L_set
13, smembers L_set can view the elements in the collection L_set
14, Sismember to see if the elements in the Redis exist, for example, Sismember l_set 4 exist return 1, otherwise return 0
15, Zadd l_set1 1 a,zadd l_set1 2,b Create a new L_set1
16, zrange L_set1 0 10 View ordered collection L_set1 The first 11 elements of the pre-ordered arrangement
17, Zrevrange L_ Set1 0-1 queries all elements in an ordered collection l_set2 that are in reverse order
18, Info [section]: Querying Redis-related information. The info command can query almost all redis information, with the following command options:

General Information for Server:redis server
Connection options for Clients:client
Memory: Storage usage Related information
Persistence:rdb and AOF related information
Stats: General Statistics
Replication:master/slave Request Information
CPU:CPU Occupancy Information Statistics
Cluster:redis Cluster Information
Keyspace: Database Information statistics
All: Return all information
Default: Returns general settings information
If the command argument is empty, the info command returns all information.

19. FLUSHDB: Empties all keys in the current database
20, Flushall: Empty All the keys in the database
21. Dbsize: Returns the total number of keys for the current database
22. Type key: Returns the data type of a key element (none: Not present, string: Character, List,set,zset,hash), key does not exist return null. Keys Key-pattern: Returns the matching key list (keys foo*: Find KEYS with the beginning of Foo case insensitive)
23, Randomkey: Randomly get an existing key, if the current database is empty, then return an empty string
24, rename A_key b_key update A_key for B_key
25. Xpire Bruce, Key named Bruce, is valid for 1000s.
26, config GET: used to read the configuration parameters running Redis server. Config SET: Used to change configuration parameters for running Redis server. AUTH: Authentication Password
27, Update password config set requirepass password or modify the configuration file by modifying/etc/redis/redis.conf.
