What is WordPress?

WordPress is a powerful and user-friendly content management system (CMS) that allows you to build and manage websites of all types—from simple blogs to complex business portals and online stores. It is open-source, highly extensible with themes and plugins, and supports everything from blogging to e-commerce via tools like WooCommerce.

Why Use AlmaLinux 9 for Hosting WordPress?

AlmaLinux 9 is a Red Hat Enterprise Linux (RHEL)-compatible operating system developed as a stable, free replacement for CentOS. It is ideal for production servers where long-term support, security, and predictable updates are essential.

Key Benefits of AlmaLinux 9:

  • 10-year support lifecycle (until 2032)
  • Binary-compatible with RHEL 9
  • Ideal for enterprise-grade WordPress deployments
  • SELinux-enabled for security
  • Compatible with tools like dnf, systemd, and firewalld

What is the LAMP Stack?

LAMP is an acronym for:

  • Linux – Operating system (AlmaLinux 9)
  • Apache – Web server
  • MariaDB – Relational database
  • PHP 8.3 – Server-side scripting language

This stack is well-known for its reliability, scalability, and widespread community support.

Why Use PHP 8.3 on AlmaLinux 9?

AlmaLinux 9 comes with older PHP versions by default (e.g., PHP 8.0), so PHP 8.3 must be installed from the Remi repository, which is actively maintained and offers the latest PHP builds.

Advantages of PHP 8.3:

  • Faster execution and lower memory usage
  • Enhanced syntax and strict typing
  • JIT (Just-In-Time) compilation support
  • Improved plugin and theme performance

MariaDB on AlmaLinux 9

MariaDB 10.5+ is included in the base repository and is fully compatible with WordPress. It stores all website content, user data, metadata, settings, and plugin information.

Recommended Configurations:

  • Use InnoDB for all tables
  • Enable slow query logging for optimization
  • Secure with mysql_secure_installation
  • Restrict remote access unless needed

Apache on AlmaLinux 9

Apache 2.4 is the default web server and is widely used for WordPress deployments.

Key Apache Features for WordPress:

  • .htaccess support for permalinks and redirects
  • Easy SSL configuration with mod_ssl
  • Compatible with mod_rewrite, mod_deflate, and http2
  • Supports virtual hosts for hosting multiple WordPress sites

Typical Use Cases

  • Small business websites and blogs
  • Corporate portals with custom themes
  • News and magazine-style sites
  • E-commerce platforms with WooCommerce
  • University and institutional websites

Security Best Practices

  • Use SELinux in enforcing mode
  • Set proper file permissions (644 for files, 755 for directories)
  • Restrict access to wp-admin or secure with HTTP Auth
  • Disable XML-RPC if unused
  • Install Fail2Ban to prevent brute-force logins
  • Use Certbot with Let’s Encrypt for free HTTPS

Performance Optimization Tips

  • Enable OPcache with PHP 8.3
  • Use caching plugins like WP Super Cache or W3 Total Cache
  • Enable GZIP compression and browser caching in Apache
  • Optimize the database with plugins like WP-Optimize
  • Use a CDN for faster delivery of images and static assets

Step 1: Set Up a Server Instance on Shape.Host

Log into your Shape.Host account.

Click “Create” and choose “Instance”.

Select a server location close to your target audience.

Pick AlmaLinux 9 (64-bit) as the operating system.

Choose a plan with at least 2 vCPU, 4 GB RAM, and 20 GB SSD.

Click “Create Instance” and wait for deployment.

Copy your new instance’s IP address for SSH access.

Step 2: Connect to Your AlmaLinux 9 Server

On Linux/macOS:

ssh root@your_server_ip

On Windows:

  • Use PuTTY, enter the IP, connect via port 22, and log in as root.

Step 3: Install WordPress with Apache, MariaDB, PHP 8.3

1. Update the System

dnf update

🔹 Updates system packages to the latest versions.

2. Install Apache Web Server

dnf install httpd

🔹 Installs the Apache HTTP server.

systemctl enable httpd

🔹 Ensures Apache starts at boot.

systemctl start httpd

🔹 Starts the Apache service now.

3. Install MariaDB Server

dnf install mariadb-server

🔹 Installs the MariaDB server package.

systemctl enable mariadb

🔹 Enables MariaDB to start on boot.

systemctl start mariadb

🔹 Starts the MariaDB service.

4. Secure the MariaDB Server

mysql_secure_installation

🔹 Set root password, remove anonymous users, disable remote root login, and remove test DB.

5. Create WordPress Database and User

mysql -u root -p

🔹 Logs into MariaDB with root credentials.

Inside the MariaDB shell:

CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'wpuser'@'localhost' IDENTIFIED BY 'strongpassword';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wpuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

🔹 Creates a dedicated database and user for WordPress.

6. Add Remi Repository for PHP 8.3

dnf install epel-release

🔹 Installs the EPEL repository.

dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm

🔹 Adds Remi’s PHP repository for RHEL 9-compatible systems.

dnf module reset php

🔹 Resets the current PHP module to allow selecting a new version.

dnf module enable php:remi-8.3

🔹 Enables PHP 8.3 from Remi repo.

7. Install PHP 8.3 and Required Extensions

dnf install php php-mysqlnd php-fpm php-curl php-dom php-exif php-fileinfo php-gd php-intl php-mbstring php-opcache php-pdo php-soap php-xml php-zip

nano wp-config.php

🔹 Edit the database settings:

define( 'DB_NAME', 'wordpress' );
define( 'DB_USER', 'wpuser' );
define( 'DB_PASSWORD', 'strongpassword' );
define( 'DB_HOST', 'localhost' );

<Directory "/var/www">
    AllowOverride All

13. Restart Apache

systemctl restart httpd

🔹 Apply the virtual host and override changes.

14. Enable HTTPS with Certbot

dnf install certbot python3-certbot-apache

🔹 Installs Certbot for managing SSL.

firewall-cmd --permanent --add-service=http

🔹 Opens port 80.

systemctl unmask firewalld
systemctl enable firewalld
systemctl start firewalld

🔹 Unmasks, enables, and starts the firewall service.

firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
