Instructions for Installing Adminer 5.3.0 on AlmaLinux 9 System
AlmaLinux 9, a binary-compatible clone of Red Hat Enterprise Linux (RHEL) 9, offers a robust and secure environment for server management. One tool that complements this system particularly well is Adminer, a lightweight, open-source web-based database management tool written in PHP.
In this article, we'll guide you through setting up Adminer on AlmaLinux 9, highlighting its advantages and common use cases.
Setting Up Adminer on AlmaLinux 9
To begin, you'll need to set up a server instance on Shape.Host. Log into your Shape.Host dashboard, create an instance, select AlmaLinux 9, and choose a plan with at least 1 vCPU, 1 GB RAM, and 10 GB SSD.
Once your instance is ready, follow these steps:
- Log in via SSH: On Windows, use PuTTY; on Linux/macOS, use the terminal. Copy the IP address for SSH access.
- Update the system: Update the system package database and install the latest updates.
- Install Apache, PHP, and necessary modules for MySQL/MariaDB support: These are installed during this step. If you're using PostgreSQL, you can add support in Step 3 as well.
- Enable and start Apache: Apache is enabled to start automatically at boot and started during this step.
- Create a new directory for Adminer: Inside Apache’s web root, a new directory is created for Adminer.
- Download and save Adminer 5.3.0 PHP file: Download the Adminer 5.3.0 PHP file and save it in the directory created in Step 5.
- Assign ownership and set permissions: Ownership of Adminer files is assigned to the Apache web server, and directory permissions are set during this step.
- Secure Adminer: To enhance security, rename the Adminer file, place it behind HTTP authentication, serve it only over HTTPS, and use a firewall like firewalld to limit open ports and access scope.
After completing these steps, Adminer 5.3.0 can be accessed via browser.
Advantages of Using Adminer on AlmaLinux 9
Adminer offers several advantages over other database management tools, particularly in its lightweight and fast performance, simplicity, and ease of use. It supports common database systems like MySQL and PostgreSQL, making it easy to deploy and manage without complex installation or configuration.
- Lightweight and faster access: Adminer is significantly lighter than alternatives such as phpMyAdmin, leading to quicker database interactions and reduced resource usage.
- Support for multiple databases: Adminer supports common database systems like MySQL and PostgreSQL, which are frequently used on AlmaLinux servers.
- Ease of deployment: As a single PHP file, Adminer can be quickly deployed without extensive configuration or dependencies, fitting well with AlmaLinux’s focus on robust, minimal environments.
- User-friendly interface: It offers a clean, straightforward interface for database management tasks such as querying, editing, and exporting data.
- Security aspects: While Adminer does not intrinsically provide advanced security features, its minimal footprint reduces potential attack surfaces relative to more complex database management tools.
Compared to other PostgreSQL management tools like DataGrip, TablePlus, and Beekeeper Studio, Adminer is less feature-rich but excels in simplicity, speed, and ease of integration on Linux servers like AlmaLinux 9.
Common Use Cases for Adminer
Adminer is a versatile tool with several common use cases. It's ideal for:
- Managing databases
- Serving as a fast admin interface for developers
- Emergency database access
In summary, the key advantages of Adminer on AlmaLinux 9 are its lightweight nature, versatility across database types, fast performance, and simplicity of use and installation, making it an efficient tool especially for server administrators who want a straightforward database management solution without additional overhead.
Technology and data-and-cloud-computing play crucial roles in setting up Adminer on AlmaLinux 9, as one requires a server instance from Shape.Host (cloud computing) and the system relies on Apache, PHP, and MySQL/MariaDB for its operation (technology).
With Adminer's ability to support multiple databases, such as MySQL and PostgreSQL, it offers a versatile and efficient solution for performing database management tasks on AlmaLinux 9, which is particularly valuable in server management and development scenarios (data-and-cloud-computing).
