What are the methods to connect to Redis?

There are several ways to connect to Redis:

1. Utilizing Redis client libraries: Redis client libraries are software libraries used to connect and communicate with a Redis server. Common Redis client libraries include redis-cli provided by Redis official, as well as Redis client libraries for various languages such as Jedis (Java), redis-py (Python), hiredis (C/C++), StackExchange.Redis (C#), node_redis (Node.js), among others. These client libraries offer interfaces and functionalities for connecting to Redis servers.
2. To connect to a Redis server and execute commands, you can use the command line tool redis-cli, which is provided by the official Redis. By running the redis-cli command, you can specify the IP address and port number of the Redis server. For example: redis-cli -h 127.0.0.1 -p 6379.
3. By using the configuration file redis.conf, the settings for connecting to the Redis server are specified in the redis.conf configuration file. Editing parameters such as bind, port, and requirepass within the redis.conf file allows for specifying the IP address, port number, and password for connecting to the Redis server. When starting the Redis server, it will connect according to the settings in the configuration file.
4. Using a connection pool: A connection pool is a mechanism for managing and maintaining multiple Redis connections. By creating and using a connection pool, it can prevent the frequent creation and destruction of Redis connections, improving the reusability and efficiency of connections. Common connection pools include Jedis’ JedisPool (Java), redis-py’s ConnectionPool (Python), StackExchange.Redis’ ConnectionMultiplexer (C#), and others.

No matter which method is used to connect to Redis, the correct IP address, port number, and password of the Redis server need to be provided (if a password is set). After a successful connection, the corresponding client library or command line tool can be used to execute Redis commands and operate Redis data.
