How to connect to redis on Linux?

To connect to Redis, you can use Redis’ client tool redis-cli or the Redis client libraries provided by programming languages.

When using redis-cli to connect to Redis, you can use the following commands:

$ redis-cli -h <hostname> -p <port>

In this case, is the hostname or IP address of the Redis server, and is the port number of the Redis server. If the Redis server is running locally and using the default port 6379, you can skip the -h and -p parameters and just run the redis-cli command.

Once connected successfully, you can use the commands provided by Redis to perform data operations, for example:

127.0.0.1:6379> set key1 value1
OK
127.0.0.1:6379> get key1
"value1"

Additionally, when accessing Redis using a programming language, it is necessary to choose the appropriate Redis client library based on the programming language being used. Popular programming languages such as Java, Python, Node.js, etc., all have corresponding Redis client libraries that can be utilized. Specific usage methods can be found in the documentation and sample code of the corresponding Redis client library.
