redis cli commands

The common commands of Redis are divided into two main parts, one is the key-value related command, the other is the server-related command1.

Redis provides rich commands for manipulating databases and various database types that can be used on Linux endpoints.1. Key-Value related commands(1)keysReturns all keys that satisfy a given parameterWith an expression *, the delegate takes out all keys(2)existsConfirm if a key exists1 means present, 0 means no(3)expireSet the expiration time for a key(4)move:T

Summary of 16 commands commonly used in Redis string type data Description: String type is the simplest type, and a key corresponding to a value,string type is binary safe. A Redis string can contain any data, such as a JPG picture or a serialized object. Common methods:1, set Method:Value for set (1) Use set for nonexistent key:

5. Basic Redis commands --- unordered set, redis command --- set1. Each element in the set is unique and has no order.2. Comparison between set and list Set List Storage content Up to 2 ^ 32-1 strings Up to 2 ^ 32-1 strings Orderliness Unordered Ordered Uniqueness Unique Not unique 3. The set uses

add your own password after requirepass in the redis configuration file. Specify the configuration again at startup File. After entering the client, we find that all operations can be entered, but all operations are rejected. Therefore, we need to authorize them and use the auth statement to keep up Password. You can also enter the password when logging on to the client, for example, redis-

4. Basic Redis commands-list, basic redis-list1. The list type is implemented using a double linked list. Therefore, if you want to add elements to both ends, the time complexity is O (1 ), the faster the element gets closer to the two ends. However, the cost is that accessing elements through indexes is slow.2. the maximum number of fields that each key can hold

The list type in Redis is somewhat similar to an array in a programming language, and the list type, as shown in the following illustration, is actually a two-way linked list structure that controls the data in the list by Lpush, Lpop, Rpush, rpop commands, so the list type can be used as a stack, can also be used as a queue. Redis Chain List List type The effi

; DEL bar tip:The parameters of the DEL command do not support wildcards , but we can combine the Linux pipeline and the Xargs command to remove all the rules that match the key. For example, to delete all the keys that start with "User:", you can execute redis-cli keys "user:*" | xargs redis-cli DEL. In addition, beca

before obtaining the value of mykey, and then the SET command is surrounded in the transaction, so that each connection can be effectively guaranteed before exec is executed, if the value of mykey obtained by the current connection is modified by the client of another connection, the exec command of the current connection will fail to be executed. In this way, the caller can determine whether the Val has been reset successfully after determining the return value.Note: Because the watch comman

). The following is a detailed description of the commands for each of the data types. Second, String type A string type is the most basic data type in Redis, and he can store any form of string, including binary data. The string type is also the basis for four other data types. That is, the other four data types are made up of string types. Common commands a
