This article focuses on how to install Memcached with EasyApache 4, providing a step-by-step guide that helps users improve their website's performance significantly.

What is Memcached?

Memcached is an open-source, high-performance, distributed memory object caching system. It is used to speed up dynamic web applications by alleviating database load. By storing data in memory, it reduces the time required for data retrieval, which significantly enhances application performance. In applications with heavy database query loads, Memcached can prove to be a game changer.

Benefits of Using Memcached

• Improved Speed: By caching data, Memcached allows for quicker data retrieval than querying a database.
• Reduced Load: Memcached minimizes the load on your database, making it more efficient and responsive.
• Scalability: It is easy to add additional Memcached servers as your application grows, ensuring it scales effortlessly.
• Flexible Object Storage: You can cache various types of data objects, including strings, arrays, and complex serializable objects.

Prerequisites for Installing Memcached

• A VPS or Dedicated Server: You can install Memcached on a virtual private server or a dedicated server that runs on CentOS.
• Root Access: You must have root or sudo access to perform installation tasks.
