In this tutorial I am will explain to you how we can configure the Redis server and use Redis as a cache in our web application.
Redis is an in-memory data structure store, used as a database, cache and message broker. It stores data in key-value which gives Redis more flexibility and performance.
Before we start this tutorial you need to have complete access to your server we need to install Redis server and also add some required PHP extension.
Installing and configure Redis
Step 1. Login to your server via terminal or putty if you are using the window.
Step 2. Once login successfully runs bellow commands.
sudo apt update sudo apt install redis-server
Step 3. Check if Redis is installed successfully using below command
sudo systemctl status redis
Step 4. Now we can check Redis server is functioning correctly, we can use redis-cli, Redis CLI is a command-line tool for Redis.
Step 5. Now if you want to restart Redis server run this command
sudo systemctl restart redis
Or, if you want to clear Redis cache you can run this command
Configure Redis for PHP extension
To use Redis with your PHP application we need an extension that connects PHP with Redis to do that we need to run below command.
sudo pecl install redis sudo apt-get install php-redis
After this, we need to restart our PHP using below command
sudo service php7.0-fpm restart
Now once your PHP restarts you are ready to use the Redis server.
Add Redis as Cache in CakePHP 3 Application
If you want to use Redis as a cache for your CakePHP 3 Application you update your cache setting in config/app.php and update your cache setting with this
'Cache' => [ 'default' => [ 'className' => 'Redis', 'path' => CACHE, 'password' => false, 'server' => '127.0.0.1', 'port' => 6379, ], '_cake_core_' => [ 'className' => 'Redis', 'prefix' => 'cake_redis_core_', 'path' => CACHE . 'persistent/', 'serialize' => true, 'duration' => '+1 years', 'server' => '127.0.0.1', 'port' => 6379, 'password' => false, ], '_cake_model_' => [ 'className' => 'Redis', 'prefix' => 'cake_redis_model_', 'path' => CACHE . 'models/', 'serialize' => true, 'duration' => '+1 years', 'server' => '127.0.0.1', 'port' => 6379, 'password' => false, ], ],
