LAMP Server Installation Guide on AlmaLinux 10
This guide shows how to set up a LAMP server (Linux, Apache, MariaDB and PHP) on AlmaLinux 10, so you can host websites without a control panel. When you finish, your server will run:
- Apache 2.4.63 web server
- MariaDB 10.11 database server (a drop-in replacement for MySQL)
- PHP 8.3, run through PHP-FPM
- A free Let's Encrypt SSL certificate for your website
AlmaLinux 10 is the newest AlmaLinux release and receives security updates until 2035. AlmaLinux 10 no longer uses module streams, so the default packages are the versions above.
The version numbers are from October 2026; regular updates may install newer releases of the same versions.
Before you start
- A server running a fresh installation of AlmaLinux 10, such as an Acenet cloud server, virtual server or dedicated server, with no control panel installed.
- Root access over SSH. Run every command in this guide as root, or put sudo in front of it.
- A domain name whose A record points to your server's IP address, for the website and SSL steps. In this guide, replace example.com with your own domain.
Step 1: Update the server
dnf -y update
If the update installed a new kernel, restart the server with reboot and log in again.
Step 2: Install Apache
dnf -y install httpd systemctl enable --now httpd
Open http://your-server-ip/ in a browser. You should see the AlmaLinux test page. If the page doesn't load, open the firewall first (step 3).
Step 3: Open the firewall
If firewalld is running (the command below prints active), allow web traffic through it:
systemctl is-active firewalld firewall-cmd --permanent --add-service=http --add-service=https firewall-cmd --reload
If you use a different firewall, allow incoming connections on ports 80 (HTTP) and 443 (HTTPS).
Step 4: Install MariaDB
Install MariaDB, start it, and secure it:
dnf -y install mariadb-server systemctl enable --now mariadb mariadb-secure-installation
The mariadb-secure-installation script asks a few questions:
- Enter current password for root: press Enter (there is none yet).
- Switch to unix_socket authentication and Change the root password: answering n is fine. The database's root user can only log in as the server's root user, through mariadb on the command line, which is secure without a password.
- Answer Y to remove anonymous users, disallow root login remotely, remove the test database and reload the privilege tables.
Step 5: Install PHP
Install PHP with PHP-FPM and the extensions most websites need (for example WordPress), then start PHP-FPM and restart Apache:
dnf -y install php php-fpm php-mysqlnd php-gd php-mbstring php-xml php-opcache php-intl php-pecl-zip systemctl enable --now php-fpm systemctl restart httpd php -v
Apache passes PHP files to PHP-FPM automatically (the configuration is in /etc/httpd/conf.d/php.conf). PHP's curl and JSON support are built in, so there are no separate packages for them.
Step 6: Test PHP
Create a test page:
echo '<?php phpinfo();' > /var/www/html/info.php
Open http://your-server-ip/info.php. You should see the PHP information page showing PHP 8.3 and Server API: FPM/FastCGI. Then delete the test page, because it shows details about your server that visitors shouldn't see:
rm /var/www/html/info.php
Step 7: Create a database and user for your website
Log in to MariaDB as root:
mariadb
Run these commands, replacing the database name, user name and password with your own (use a long, random password):
CREATE DATABASE exampledb; CREATE USER 'exampleuser'@'localhost' IDENTIFIED BY 'a-strong-password'; GRANT ALL PRIVILEGES ON exampledb.* TO 'exampleuser'@'localhost'; FLUSH PRIVILEGES; EXIT;
Your website's software connects with these details and host localhost.
Step 8: Set up your website
Each website gets its own folder and its own Apache configuration file (a "virtual host").
1. Create the folder and give it to Apache's user:
mkdir -p /var/www/example.com/public_html chown -R apache:apache /var/www/example.com
2. Create /etc/httpd/conf.d/example.com.conf:
<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com/public_html
<Directory /var/www/example.com/public_html>
AllowOverride All
Require all granted
</Directory>
ErrorLog /var/log/httpd/example.com-error.log
CustomLog /var/log/httpd/example.com-access.log combined
</VirtualHost>
3. Check the configuration and reload Apache:
apachectl configtest systemctl reload httpd
Upload your website's files to /var/www/example.com/public_html. AllowOverride All lets the website use .htaccess files, which many applications need.
SELinux
AlmaLinux 10 has SELinux turned on. Files in /var/www are already labeled so Apache can read them, but Apache can't write to them. If your website needs to write files (for example uploads or a cache folder), label that folder as writable, replacing the path with your own:
dnf -y install policycoreutils-python-utils semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/example.com/public_html/wp-content(/.*)?" restorecon -Rv /var/www/example.com/public_html/wp-content
If your website connects to a database or an API on another server, also allow Apache to make network connections:
setsebool -P httpd_can_network_connect 1
Step 9: Add a free SSL certificate
Install Certbot from the EPEL repository, along with Apache's SSL module:
dnf -y install epel-release dnf -y install certbot python3-certbot-apache mod_ssl systemctl restart httpd certbot --apache -d example.com -d www.example.com
The restart creates the default certificate that Apache's SSL module expects. Without it, Certbot stops with an Apache configuration error.
Certbot asks for an email address for renewal notices, gets the certificate, and adds an HTTPS virtual host for your website. When it asks, choose to redirect HTTP to HTTPS.
Let's Encrypt certificates last 90 days. Turn on automatic renewal and test it:
systemctl enable --now certbot-renew.timer certbot renew --dry-run
Keep your server updated
Install updates regularly, so you get security fixes for Apache, MariaDB, PHP and the operating system:
dnf -y update
To install security updates automatically, you can use dnf-automatic.
