Guide on Installing Adminer Version 5.3.0 in Rocky Linux 9
In this article, we will guide you through the process of installing Adminer 5.3.0 on Rocky Linux 9 using Apache and PHP. Adminer is a fast, lightweight, and open-source web-based database management tool that offers full support for CRUD operations and table structure management, import/export tools, SQL editor with syntax highlighting, user and privilege management, and a plugin system for extending functionality.
**Step 1: Update your system**
Begin by updating your system:
```bash sudo dnf update -y ```
**Step 2: Install Apache and PHP**
Rocky Linux 9 typically comes with PHP 8.x. Adminer 5.3.0 supports PHP 5.2 and newer, so PHP 8.x will work fine. Install Apache and PHP along with the necessary PHP modules:
```bash sudo dnf install httpd php php-mbstring -y ```
**Step 3: Start and enable Apache web server**
Start the Apache web server and ensure it starts automatically on boot:
```bash sudo systemctl start httpd sudo systemctl enable httpd ```
Verify Apache is running:
```bash sudo systemctl status httpd ```
**Step 4: Download Adminer 5.3.0**
Navigate to the web root, typically `/var/www/html`:
```bash cd /var/www/html ```
Download Adminer 5.3.0 single PHP file:
```bash sudo curl -O https://github.com/vrana/adminer/releases/download/v5.3.0/adminer-5.3.0.php ```
For convenience, rename the file to `adminer.php`:
```bash sudo mv adminer-5.3.0.php adminer.php ```
**Step 5: Set proper permissions**
Ensure Apache can read the file:
```bash sudo chown apache:apache adminer.php sudo chmod 644 adminer.php ```
**Step 6: Adjust Firewall (if necessary)**
If firewall is running, allow HTTP traffic:
```bash sudo firewall-cmd --zone=public --add-service=http --permanent sudo firewall-cmd --reload ```
**Step 7: Test Adminer**
Open your browser and go to:
``` http://your-server-ip/adminer.php ```
You should see the Adminer login page.
**Optional: Secure Adminer by Apache configuration**
For security reasons, you may want to restrict access to Adminer by IP or set up HTTP authentication. Example: Allow only localhost access:
1. Create a file `/etc/httpd/conf.d/adminer.conf`:
```apache ```
2. Reload Apache:
```bash sudo systemctl reload httpd ```
**Summary**
```bash sudo dnf update -y sudo dnf install httpd php php-mbstring -y sudo systemctl start httpd sudo systemctl enable httpd
cd /var/www/html sudo curl -O https://github.com/vrana/adminer/releases/download/v5.3.0/adminer-5.3.0.php sudo mv adminer-5.3.0.php adminer.php sudo chown apache:apache adminer.php sudo chmod 644 adminer.php
sudo firewall-cmd --zone=public --add-service=http --permanent sudo firewall-cmd --reload ```
Open `http://your-server-ip/adminer.php` and you're done.
