What is the default port number of redis?
Redis is an open source log-type Key-Value database written in ANSI C language, supports network, can be memory-based and persistent, and provides APIs in multiple languages. The default port number of redis is 6379.
Why does Redis choose 6379 as the default port number?
6379 is the number corresponding to MERZ on the phone button, and MERZ is taken from the name of Italian singer Alessia Merz.
Alessia Merz is an Italian dancer and actress. Antirez, the author of Redis, watched TV shows in his early years and felt that some of Merz's words in the show were stupid and ridiculous. Antirez liked to make "memes" for daily communication with friends, so he coined the word "MERZ" to describe stupidity, which has the same meaning as "stupid" same.
Later Antirez redefined "MERZ", describing it as "having a high technical value, including skill, patience and labor, but still maintaining a simple essence."
When it came time to choose a number as the default port number for Redis, Antirez didn't think much and used the number 6379 corresponding to "MERZ" on the mobile phone keyboard.

How to build the redis cluster mode
Apr 10, 2025 pm 10:15 PM
Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make
How to clear redis data
Apr 10, 2025 pm 10:06 PM
How to clear Redis data: Use the FLUSHALL command to clear all key values. Use the FLUSHDB command to clear the key value of the currently selected database. Use SELECT to switch databases, and then use FLUSHDB to clear multiple databases. Use the DEL command to delete a specific key. Use the redis-cli tool to clear the data.
How to use the redis command
Apr 10, 2025 pm 08:45 PM
Using the Redis directive requires the following steps: Open the Redis client. Enter the command (verb key value). Provides the required parameters (varies from instruction to instruction). Press Enter to execute the command. Redis returns a response indicating the result of the operation (usually OK or -ERR).
How to use single threaded redis
Apr 10, 2025 pm 07:12 PM
Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.
How to read the source code of redis
Apr 10, 2025 pm 08:27 PM
The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.
How to read redis queue
Apr 10, 2025 pm 10:12 PM
To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.
How to view all keys in redis
Apr 10, 2025 pm 07:15 PM
To view all keys in Redis, there are three ways: use the KEYS command to return all keys that match the specified pattern; use the SCAN command to iterate over the keys and return a set of keys; use the INFO command to get the total number of keys.
How to implement the underlying redis
Apr 10, 2025 pm 07:21 PM
Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.
