Install Let’s Encrypt SSL Certificate

Let's issue an SSL certificate for the domain. For this, we will need the EPEL repository and the mod_ssl package on Rocky Linux 8 operating system.

Update and install EPEL repository and the mod_ssl package on the system using the below command:

dnf install epel-release mod_ssl -y

Next, we will install the certbot client which is used to create Let's Encrypt certificates:

dnf install python3-certbot-nginx -y

Install SSL Certificate

Use the certbot command to issue a Let's Encrypt certificate. Replace and with your domain name and email :

certbot --nginx --agree-tos --redirect --hsts --staple-ocsp --email -d

SSL certificates are valid for 90 days. The renewal process is now automated, you do not have to renew this manually.

Enable Firewall:

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

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

firewall-cmd --reload

Restart Nginx

Restart apache to avoid getting error messages.

systemctl restart nginx

Now you have successfully installed Let's Encrypt SSL with LEMP Stack on Rocky Linux 8.
