MySQL Performance: MySQL/MariaDB Indexes
Data in a MySQL/MariaDB database is stored in tables. A simple way of thinking about indexes is to imagine an extensive spreadsheet. This type of system is not always conducive to quick searching; that’s where an index becomes essential. If there is no index, then the database engine has to start at row one and browse through all the rows looking for the corresponding values. If this is a small table, then it is no big deal, but in larger tables and applications where there can be tables with millions and even billions of rows, it becomes problematic. As you can imagine, searching through those rows one by one will be time-consuming, even on the latest hardware. The solution is to create an INDEX (or more than one) for your data.

How To Install the LAMP Stack on CentOS 7
Whether you’re new to hosting websites or a seasoned developer, you’ve more than likely heard of a LAMP stack. The LAMP stack is the base set of applications that most websites running on a Linux server are served from and is commonly referred to as “Lamp”. Rather than a single program that interacts with the website being served, LAMP is actually a number of independent programs that operate in tandem: Linux, Apache, MySQL/MariaDB, and PHP. Throughout this article, we’ll walk through installing the LAMP stack on your CentOS 7 server so you can run a website from any Dedicated Server or Virtual Private Server. Although we’re focusing on installing LAMP on a CentOS 7 server, the steps that we’ll cover are very similar across multiple Linux distributions.
Similar to Dropbox and Google Drive, Nextcloud is self-hosting software that allows you to share files, contacts, and calendars. But, unlike Dropbox and Google Drive, your files will be private and stored on your server instead of a third-party server. Nextcloud is a GDPR and HIPAA compliant hosting solution, so your files will be encrypted along with the ability to audit. For this tutorial, we’ll be installing our Nextcloud instance on our Ubuntu VPS server.
