Enabling the Redis extension for PHP

Redis is an in‑memory data structure store often used as a cache or session handler to improve application performance. To use Redis with PHP applications (like Laravel, WordPress, or Magento) on ruachost.com, you need to enable the Redis extension.

Why Enable Redis?

Provides faster caching and session management.
Reduces database load by storing frequently accessed data in memory.
Improves scalability for high‑traffic websites.
Compatible with all ruachost.com hosting accounts.

Steps to Enable Redis Extension for PHP

1. Check PHP Version

Log in to cPanel at ruachost.com.
Go to Select PHP Version under the Software section.
Confirm your PHP version supports Redis (PHP 7.4+ recommended).

2. Enable Redis via PHP Selector

In Select PHP Version, look for the redis extension in the list.
Check the box next to redis.
Click Save to apply changes.

3. Verify Redis Installation

Create a phpinfo.php file in your public_html directory:
```
<?php phpinfo(); ?>
```
Visit http://example.com/phpinfo.php.
Search for redis in the output.
If enabled, you’ll see Redis extension details.

4. Configure Redis in Your Application

For Laravel:

Update .env file:

CACHE_DRIVER=redis
SESSION_DRIVER=redis
REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

For WordPress:
- Install a Redis plugin (e.g., Redis Object Cache).
- Add to wp-config.php:
```
define('WP_REDIS_HOST', '127.0.0.1');
define('WP_REDIS_PORT', 6379);
```

5. Test Redis Connection

Run a simple PHP script:

<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to Redis successful!";
?>

If successful, Redis is ready for use.
