How to setup Samba Server and client on AlmaLinux

10 April 2021 by Korbin Brown

File servers often need to accommodate a variety of different client systems. Running Samba allows Windows systems to connect and access files, as well as other Linux systems and MacOS. An alternative solution would be to run an FTP/SFTP server, which can also support the connections from many systems.

In this guide, we’ll go over the instructions to setup a Samba server on AlmaLinux. This is a great way to prepare your file server after installing AlmaLinux or migrating from CentOS to AlmaLinux. We’ll also see how to connect to the file server from other AlmaLinux client computers.

In this tutorial you will learn:

How to install Samba on AlmaLinux
How to allow Samba through firewalld
How to create a Samba user
How to configure Samba to share a directory
How to allow Samba through SELinux
How to connect to Samba server from AlmaLinux client

How to configure NTP server and client on AlmaLinux

22 March 2021 by Korbin Brown

NTP stands for Network Time Protocol and is used for clock synchronization across multiple computers. An NTP server is responsible for keeping a set of computers in sync with each other. On a local network, the server should be able to keep all client systems to within a single millisecond of each other.

Such a configuration would be necessary if, for example, the systems needed to start or stop a task in unison at a precise time. In this article, we’ll show you how to configure an NTP server on AlmaLinux and how to configure a client system to sync its system time with said server. This can be done from a fresh AlmaLinux installation or on a system that has migrated from CentOS to AlmaLinux.

In this tutorial you will learn:

How to install and configure chrony NTP server
How to open firewall to incoming NTP requests
How to connect to an NTP server from a client machine

Setting up a MySQL database and user on AlmaLinux

How to install MySQL on AlmaLinux

22 March 2021 by Korbin Brown

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.

LEMP stack running successfully on AlmaLinux

How to install LEMP stack on AlmaLinux

22 March 2021 by Korbin Brown

A LEMP 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 LEMP acronym, namely the Linux operating system, NGINX web server, MySQL database (or MariaDB alternatively), and PHP programming language.

If you’ve installed AlmaLinux or migrated from CentOS to AlmaLinux, then you already have the first requirement done. Next, you just need to get your LEMP stack up and running. In this guide, we’ll show the step by step instructions to install a LEMP stack on AlmaLinux.

Note that it’s also possible to install a LAMP stack on AlmaLinux, which is very similar to LEMP except that it contains Apache as the web server instead of NGINX.

In this tutorial you will learn:

How to install all LEMP prerequisite packages on AlmaLinux
How to secure MariaDB database
How to start NGINX and MariaDB services
How to open HTTP and HTTPS firewall ports

How to run the Raspberry Pi Os in a virtual machine with Qemu and Kvm

23 February 2021 by Egidio Docile

Although many operating system are available for the Raspberry Pi, the official one is the Raspberry Pi Os. The operating system is made to run for the arm architecture, and can be easily installed on the SD card which will be used as the main Raspberry Pi storage device. Sometimes we may want to perform some tests or try some applications without having a physical Raspberry Pi machine; in this tutorial we will see how we can create a virtual machine with the Raspberry Pi Os system using Qemu and Kvm (Kernel Virtual Machine).

In this tutorial you will learn:

How to install qemu and kvm
How to download and check the integrity of the latest Raspberry Pi Os version (Buster)

Change hostname on AlmaLinux

18 February 2021 by Korbin Brown

The hostname of a Linux system is important because it’s used to identify the device on a network. The hostname is also shown in other prominent places, such as in the terminal prompt. This gives you a constant reminder of which system you’re working with. It’s a real life saver when you’re managing multiple systems through SSH and those command line terminals start to blend together in your mind.

Of course, IP addresses are used when devices need to communicate with each other, but those can change frequently. Hostnames give us a way to know which device we’re interacting with either on the network or physically, without remembering a bunch of numbers that are subject to change. Thus, it’s important that your system bears a hostname which helps you to identify it quickly. For example, “backup-server” is much more informative than “server2.” If you can’t easily identify a system’s purpose from the hostname, it’s time to change it.

In this guide, we’ll show you how to change the hostname on AlmaLinux. This can be especially useful if you’ve recently migrated from CentOS to AlmaLinux and need to update the hostname accordingly. Changing the hostname can be done either by command line or GUI, and we’ll show you the steps for both methods below.

In this tutorial you will learn:

How to change the AlmaLinux hostname from command line
How to change the AlmaLinux hostname from GNOME GUI

Rocky Linux download

22 December 2020 by Korbin Brown

Rocky Linux is an upcoming Linux distribution that will be based on Red Hat Enterprise Linux. For other most popular Linux distributions, please visit our dedicated Linux download page.

For many years, CentOS Linux was a reliable, enterprise-ready distribution based on RHEL. In late 2020, Red Hat announced a change of direction for the distro, which would now be named “CentOS Stream” and exist as an upstream vendor.

In response, CentOS founder Gregory Kurtzer launched Rocky Linux, a project that will inherit the original goals of CentOS. Being based on RHEL means that it will only inherit the most tested and stable components that have been introduced upstream in Fedora and CentOS Stream.

Not much is known about the new distro at this time, except that it should function similarly to CentOS (the CentOS before this change) and will most likely be an appropriate replacement for it. You can stay abreast of the latest news by visiting the official Rocky Linux site, as well as Rocky’s GitHub. We’ll also be updating this article as new information is revealed.
