Redis is an open source, high-performance key-value storage database that is widely used in Scenarios such as caching and message queues. Installing the Redis extension under the Linux system allows us to use the Redis database more efficiently. This article will introduce in detail how to install the Redis extension under Linux system and provide specific code examples.

Step 1: Install Redis

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$redis->set('test_key', 'Hello, Redis!');
echo $redis->get('test_key');
?>

2. Execute the PHP script:

php test_redis.php

If everything goes well, Hello, Redis! , indicating that the Redis extension has been successfully installed and connected to the Redis server.

Summary

Through the above steps, you have successfully installed the Redis extension under the Linux system and conducted a simple test. Now you can use Redis database in PHP projects to improve performance and efficiency. Hope this article is helpful to you!
