How to install Certbot on AlmaLinux with Apache

Securing our website with HTTPS has become a key part of ensuring data integrity and user privacy in today’s world.

Certbot streamlines the process of obtaining free SSL/TLS certificates from Let’s Encrypt and configuring web servers like Nginx or Apache.

Today, we are going to take a look at installing Certbot on AlmaLinux 9. We will also get a quick peek at effortlessly obtaining and configuring SSL certificates.

How to install Certbot on AlmaLinux 9 with Apache

1. To begin with, we have to make sure our system is up-to-date by running these commands with root privileges:

   # yum install epel-release
2. Next, we can install Certbot as seen here:
   • For Nginx:

     # dnf install certbot python3-certbot-nginx
   • For Apache:

     # dnf install certbot python3-certbot-apache mod_ssl
3. After that, it is time to obtain and configure Certificates:
   • For Nginx:

     # certbot --nginx
   • For Apache:

     # certbot --apache
4. Then, we have to check the Certbot version to verify if the installation was successful:

   # certbot --version

Installing Certbot on AlmaLinux 8

1. First, make sure the system is up-to-date and install the necessary repository:

   sudo dnf update
sudo dnf install epel-release

2. Then, install Certbot as seen here:
   • For Apache:

     sudo dnf install certbot python3-certbot-apache mod_ssl
   • For Nginx:

     sudo dnf install certbot python3-certbot-nginx
3. Now, get an SSL certificate with Certbot by specifying the web server.

   For example:
   sudo certbot --apache

   Here the web server in use is Apache.
4. Then, we have to make sure that proper firewall rules for HTTP (port 80) and HTTPS (port 443) are in place:

   sudo firewall-cmd --permanent --add-port=80/tcp --zone=public
sudo firewall-cmd --permanent --add-port=443/tcp --zone=public
sudo firewall-cmd --reload

5. Finally, verify HTTPS enablement as seen here:
   firewall-cmd --list-all

   In case port 443 is disabled we can enable it via firewalld or iptables.

   • For firewalld:

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

   • For iptables:

     iptables -I INPUT -p tcp -m tcp --dport 443 -j ACCEPT
iptables-save
