How to Enable Memcached in DirectAdmin?

Memcached is a distributed memory object caching technology that is free and open-source. Its goal is to reduce the stress on databases and other external data sources in order to speed up dynamic web applications. Memcached is crucial for various reasons.

• Performance Improvement: Memcached speeds up application response times and enhances user experience by drastically cutting down on the amount of time required to access frequently used data by caching it in memory.

• Scalability: Memcached is a vital tool for managing heavy traffic and big datasets because of its distributed architecture, which makes it easy to scale with the expansion of an application.

• Resource Efficiency: Memcached helps to reduce total resource utilization, which results in a more efficient use of system resources by easing the burden on databases.

With a simple graphical interface, users can easily manage domains, email accounts, databases, files, and server settings with DirectAdmin, a web-based control panel for web hosting setups.

Steps to Enable Memcached in DirectAdmin

1. Install Memcached and Required Packages: We can use the package manager (e.g., yum for CentOS) to install:

yum install memcached memcached-devel libmemcached-devel libmemcached

Here,

memcached: The main server.

memcached-devel: Development files needed for the PHP extension.

libmemcached-devel and libmemcached: Client libraries for Memcached.

2. Start and Enable Memcached:

i. Start Memcached:

systemctl start memcached

ii. Enable Memcached on boot:

systemctl enable memcached

iii. For older systems without systemctl:

/etc/init.d/memcached start
chkconfig memcached on

3. Install the Memcached PHP Extension:

i. Then, download and install libmemcached:

wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
gunzip libmemcached-1.0.18.tar.gz
tar -xvf libmemcached-1.0.18.tar
cd libmemcached-1.0.18
./configure
make && make install

ii. Download and install the PHP extension:

wget https://pecl.php.net/get/memcached-3.0.4.tgz
tar -xvzf memcached-3.0.4.tgz
cd memcached-3.0.4
phpize
./configure
make && make install

4. Configure PHP to Use Memcached:

i. Locate the php.ini file:

php -i | grep "php.ini"

ii. Add the extension to php.ini:

echo "extension = /usr/local/lib/php/extensions/no-debug-non-zts-20160303/memcached.so" >> /path/to/your/php.ini

iii. Restart the web server:

/etc/init.d/httpd restart

5. Verify the Installation:

i. Check if the Memcached extension is loaded:

php -m | grep memcached

ii. Test Memcached using a PHP script or telnet to ensure it works.

This steps ensures that Memcached is properly set up and integrated with PHP in DirectAdmin, improving the server’s performance.

Benefits of Using Memcached in DirectAdmin

We’ll be having the following benefits for using Memcached in DirectAdmin:

• Enhanced Performance: Memcached reduces database queries and server load, enhancing response times and accelerating dynamic online applications.

• Improved Scalability: Memcached’s distributed architecture makes it simple to scale up and down in response to spikes in traffic without sacrificing performance.

• Decreased Database Load: By storing frequently requested data, Memcached lowers database queries while also extending the life of database servers and saving maintenance expenses.

• Improved Resource Utilization: Memcached ensures effective system resource use by reallocating memory to regions of greater need. This improves memory consumption.

• Support for Multiple Languages: Memcached makes it easier to integrate into a variety of applications and contexts by offering APIs for the majority of widely used programming languages.
