How to Install Mattermost on MXLinux Latest

Mattermost is a powerful and secure messaging platform that can be self-hosted by businesses and organizations. In this tutorial, we will learn how to install Mattermost on MXLinux Latest.

Preparing to Install Mattermost

Before we start with the installation, we need to ensure that our system meets the following requirements:

• A server with at least 2GB of RAM and 20GB of free disk space.

Installing Mattermost

Mattermost requires a supported database, which we will install first.

Installing MariaDB

   sudo apt update
   

2. Install MariaDB:

   sudo apt install mariadb-server
   

3. Secure the MariaDB installation by running the following command:

   This script will guide you through the process of securing MariaDB. Follow the prompts and set a secure password for the root user.

Creating a Database and User for Mattermost

1. Open the MariaDB shell:

   sudo mysql
   

2. Create a new database for Mattermost:

   CREATE DATABASE mattermost;
   

3. Create a new user with the required privileges:

   CREATE USER 'mattermost'@'localhost' IDENTIFIED BY 'password';
   GRANT ALL PRIVILEGES ON mattermost.* TO 'mattermost'@'localhost';
   FLUSH PRIVILEGES;
   

   Replace "password" with a secure password.

4. Exit the MariaDB shell:

   exit
