How to set a password for Redis
There are two ways to set the redis password, one requires restarting the redis service, and the other does not require restarting the redis service. The following article will introduce these two methods to you, I hope it will be helpful to you.
Method 1: Set through the configuration file (/etc/redis.conf)
In this method, after setting the password You need to restart redis to take effect. First find the redis configuration file—redis.conf file, and then modify the requirepass inside (requirepass is the parameter for configuring the redis access password). This is originally commented out. Remove the comment and set the corresponding fields to what you want. Password required, save and exit. Just restart the redis service. (Recommended learning: Redis video tutorial)
I set the password here to 123
Method 2: Pass Command to set password
This method is relatively simple and does not require restarting the redis service. After connecting to redis, set it through the command, as follows:
config set requirepass 123456
In this way, the password is set to 123456
After setting, you can check the password through the following command
config get requirepass
After setting the password, when you exit and connect to redis again, you need to enter the password, otherwise it will not work. There are two ways to enter the password. One is to enter the password directly when connecting, but to enter the password after connecting, as follows:
Note: Through the command After you change the password, the password behind the requirepass field in the configuration file (/etc/redis.conf) will not be changed accordingly.

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

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.

To view the Redis version number, you can use the following three methods: (1) enter the INFO command, (2) start the server with the --version option, and (3) view the configuration file.

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.

Steps to solve the problem that redis-server cannot find: Check the installation to make sure Redis is installed correctly; set the environment variables REDIS_HOST and REDIS_PORT; start the Redis server redis-server; check whether the server is running redis-cli ping.

Redis Ordered Sets (ZSets) are used to store ordered elements and sort by associated scores. The steps to use ZSet include: 1. Create a ZSet; 2. Add a member; 3. Get a member score; 4. Get a ranking; 5. Get a member in the ranking range; 6. Delete a member; 7. Get the number of elements; 8. Get the number of members in the score range.

Redis uses five strategies to ensure the uniqueness of keys: 1. Namespace separation; 2. HASH data structure; 3. SET data structure; 4. Special characters of string keys; 5. Lua script verification. The choice of specific strategies depends on data organization, performance, and scalability requirements.

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.
