The purpose of this tutorial is to show how to access MySQL remotely with the root account. Conventional security practice is to disable remote access for the root account, but it is very simple to turn on that access in a Linux system.

MySQL: Allow all hosts
If you wish to access your MySQL server remotely, it will be necessary to configure one or more users to allow access from remote hosts. If you do not know all the IP addresses of the connecting hosts, then you can simply allow connections from all hosts.
MySQL: Allow empty password
If you have installed MySQL on your Linux system and need to have one or more users with an empty password, it is possible to either create new users with empty passwords or reset an existing user’s password to being empty.
MySQL: Allow user to create database
After installing MySQL on your Linux system, you can create one or more users and grant them permissions to do things like create databases, access table data, etc.
MySQL: Allow user access to database
After installing MySQL on your Linux system and creating a new database, you will need to setup a new user to access that database, granting it permissions to read and/or write data to it.
MySQL: Allow access from specific IP address
If you need to allow remote access to your MySQL server, a good security practice is to only allow access from one or more specific IP addresses. This way, you are not needlessly exposing an attack vector to the entire internet.
MySQL: Allow remote connections
After installing a MySQL server on a Linux system, by default it will only accept incoming connections from itself (i.e. the loopback address 127.0.0.1).
Introduction to MySQL storage engines
MySQL is probably the most famous Relational Database Management System (RDBMS). Developed as a free and open source software, it was originally backed by the MYSQL AB company, but is now owned by Oracle. In MySQL the “storage engine” used for a table determines how data is handled.
Ubuntu 22.04 LAMP installation
A LAMP stack is an assortment of software that contains everything you need in order to serve a website, show dynamic content, and store or retrieve data from a database. The software is all within the LAMP acronym, namely the Linux operating system, Apache web server, MySQL database (or MariaDB alternatively), and PHP programming language.
Linux commands to back up and restore MySQL database
It’s always a good idea to take frequent backups of your MySQL or MariaDB databases. They can potentially contain thousands of lines of irreplaceable data. Many users may be confused on how to back up their databases at first, as the process differs quite a bit from backing up ordinary files. The process of restoring a backup must also be known, as there’s no point in having a backup if the user cannot reliably restore it.
In this guide, we’ll go over various command line examples to back up and restore MySQL or MariaDB databases on a Linux system. You can then use these commands to make regular backups of your databases, or even add them to a Bash script that can do most of the work for you. Another option is to configure cron to make regularly scheduled backups of your databases.
In this tutorial you will learn:
- How to back up MySQL or MariaDB database (one or multiple)
- How to restore a MySQL or MariaDB database backup
WordPress Installation on Ubuntu Linux with Apache and MySQL
WordPress has remained one of the best and easiest ways to get a sleek site up and running ever since its inception in 2003. As a matter of fact, current trends only show its popularity continuing to increase. WordPress is simple to use, and even hosting it yourself isn’t that hard, as we’ll prove to you in this article.
In this guide, we’ll show you how to get your site hosted with WordPress on Ubuntu Linux. We’ll use Apache as our HTTP server, and also install PHP and MariaDB (an open source implementation of MySQL) since WordPress requires them in order to function. This assortment of packages is commonly referred to as a LAMP stack (Linux, Apache, MySQL, PHP). Once those packages are installed, we’ll go over the configuration of Apache and MySQL, including initial setup of a database and user, before installing WordPress itself. Towards the end, we’ll also show you how to configure a self signed SSL certificate, or get a free one from Let’s Encrypt, which enables your site to utilize HTTPS.
In this tutorial you will learn:
- How to install and configure Apache
- How to install and configure MariaDB for MySQL
- How to setup a MySQL user and database for WordPress
- How to download and install WordPress
- How to configure a self signed SSL certificate for your WordPress site
- How to configure a free SSL certificate from Let’s Encrypt
How to install MySQL on AlmaLinux
In this guide, we will show you how to install MySQL on AlmaLinux. There are two separate packages for this on AlmaLinux, depending on what you need to do. You can either install the MySQL client package, which is used to connect to MySQL servers, or install the MySQL server software, which can be used to host your own databases. We’ll cover both below.
After installing a MySQL server, we’ll also go over the first steps you’ll need to get started with hosting a database, which includes making a username and password, creating a database, and granting user permissions on that database. AlmaLinux is a good Linux distro for hosting MySQL, whether you’ve freshly installed AlmaLinux or migrated from CentOS to AlmaLinux.
In this tutorial you will learn:
- Install MySQL Client on AlmaLinux
- Install MySQL Server on AlmaLinux
- How to setup a MySQL database
