# Install Memcached PHP Extension on Ubuntu

The following instructions are specifically for installing the Memcached PHP Extension on a single Ubuntu node. If you have not yet installed Memcached on Ubuntu, please see our article [Installing Memcached on Ubuntu](https://docs.nexcess.com/hosting/server-administration/linux/installing-memcached-on-ubuntu/). The extension will not work without it installed first.

1. First, update your packages:  
    ```
    apt-get update
    ```
2. Then install the PHP Memcached extension and related packages:  
    ```
    apt-get install php5-memcached
    ```
3. The last step is to verify the installation. Use the following command to view information on the installed PHP modules:  
    ```
    php -m | grep memcached
    ```
