Installing Adminer 5.3.0 on AlmaLinux 9: A Step-by-Step Guide
In this article, we'll guide you through the process of connecting to a server via SSH on Linux/macOS and AlmaLinux 9, and the installation of Adminer, a lightweight, open-source web-based database management tool.
Connecting to the Server
To connect to a server via SSH on Linux/macOS, open a terminal and use the SSH command followed by the IP address of the server. For Windows users, you can use PuTTY to connect to the server with the IP address.
Installing AlmaLinux 9
AlmaLinux 9, a binary-compatible clone of Red Hat Enterprise Linux (RHEL) 9, is designed for long-term stability and security. To set up a server instance on Shape.Host, log into the dashboard, create an instance, select a data center region, choose AlmaLinux 9 (64-bit) as the OS, pick a plan with at least 1 vCPU, 1 GB RAM, and 10 GB SSD, and click Create Instance.
Updating the System and Installing Necessary Packages
Once the instance is ready, update the system package database and install the latest updates. This process also includes the installation of Apache, PHP, and necessary modules for MySQL/MariaDB support.
Installing Adminer on AlmaLinux 9
In Step 5, a new directory for Adminer is created inside Apache's web root. Adminer 5.3.0, downloaded and saved in the Adminer directory in Step 7, offers core features such as single-file PHP deployment, web UI for managing databases, support for data export/import, raw SQL execution, plugin support, interface themes, and localization support.
Adminer 5.3.0 supports multiple database types including MySQL/MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, and others. It is fully compatible with PHP 8.1 (the default in AlmaLinux 9) and PHP 8.3 (via the Remi repository).
Configuring Adminer on AlmaLinux 9
To ensure the secure use of Adminer, it's recommended to rename the file, place it behind HTTP authentication or restrict it by IP, serve it over HTTPS, delete the file or disable its URL after use, ensure proper file contexts with SELinux, and use a firewall like firewalld to limit open ports and access scope.
Ownership of Adminer files is assigned to the Apache web server and directory permissions are set in Step 8. Apache is enabled and started in Step 4, ensuring it starts automatically at boot and is currently running.
Accessing Adminer on AlmaLinux 9
Adminer 5.3.0 can be accessed via browser after following the steps mentioned above. It offers a full-featured UI for executing queries, managing tables, users, and exporting/importing data through a simple browser interface.
In summary, the system requirements for running Adminer 5.3.0 on AlmaLinux 9 are AlmaLinux 9 itself, an installed and configured PHP (preferably PHP 7.4 or newer, commonly PHP 8.x on AlmaLinux 9), a web server (Apache or Nginx), and access to the database you want to manage (e.g., MySQL/MariaDB server). Adminer itself does not have specific or unusual system requirements beyond the typical software stack needed to run it.
Technology plays a crucial role in the process of connecting to a server via SSH on various platforms and installing Adminer, a powerful database management tool. Data-and-cloud-computing technologies, such as AlmaLinux 9, act as the foundation for these operations, offering long-term stability, security, and compatibility with modern web-based applications like Adminer.
