Prerequisites
Before you begin, make sure:
- ✅ Memcached is enabled on your hosting account – How to Enable Memcached on Your Hosting Plan
- ✅ You have FTP or file manager access to your Joomla site’s root folder
- ✅ You have administrator access to your Joomla admin panel
Step 1: Edit the Joomla Configuration File
To enable Memcached on Joomla, you need to modify a few settings in your Joomla configuration.php file first.
Locate the File
You can find this file in your Joomla site’s root folder (usually /www/yourdomain.com/ or the folder where Joomla is installed).
Edit the File
Using your favorite FTP software or the File Manager in your hosting control panel:
- Open the
configuration.phpfile for editing. - Find the following lines:
php
public $caching = '0'; public $cache_handler = 'file';
- Change these lines to:
php
public $caching = '2'; public $cache_handler = 'memcache';
- Immediately after the two lines you edited, add these two lines:
php
public $memcache_server_host = '/home/sys/memcached.sock'; public $memcache_server_port = '0';
- Save the file and close it.
Note: This guide is written for KamHost hosting, which uses a Unix socket for Memcached connections. If your hosting provider uses a different socket path or TCP/IP instead of a socket, replace
/home/sys/memcached.sockwith your specific host details (e.g.,127.0.0.1and port11211).
Step 2: Configure Memcached in Joomla Settings
Now, we’ll configure Memcached in your Joomla site’s admin panel.
- Log in to your Joomla admin panel.
- Navigate to System → Global Configuration.
- Click on the Server tab at the top.
- Scroll down to Cache Settings.
- From the drop-down menu, select Persistent (Memcached).
- Enter your Memcached server details:
| Setting | Value |
|---|---|
| Memcache(d) Server Host | /home/sys/memcached.sock |
| Memcache(d) Server Port | 0 |
- Click Save at the top to apply your changes.
Step 3: Verify Memcached Is Working
To confirm Memcached is active on your Joomla site:
- Visit your Joomla site’s frontend and browse a few pages.
- Check if pages load faster – you should notice improved performance.
- You can also check your hosting control panel’s Memcached statistics to see cache hits.
