How To Setup LetsEncrypt SSL Certificate with Apache on Rocky Linux 8

Let's Encrypt is a non-profit certificate authority run by Internet Security Research Group that provides X.509 certificates for Transport Layer Security encryption at no charge. In this article, we are going to learn how to install Let's Encrypt SSL on Rocky Linux 9. So, let’s get started.

Install EPEL Repo in Rocky Linux

For install SSL Below command:

dnf install epel-release mod_ssl

Output:

[root@vps ~]# dnf install epel-release mod_ssl

Next,install Certbot in Rocky Linux

 dnf install certbot python3-certbot-apache 

Configuring Apache vHost

In this article we are using blog.domainhere.info as an example domain. You would need to replace this with your actual domain name.

Create a new apache configuration file blog.domainhere.info.conf for the domain with the following command:

nano /etc/httpd/conf.d/blog.domainhere.info.conf

Add the following codes:

  <VirtualHost *:80>
  ServerName blog.domainhere.info
  ServerAlias blog.domainhere.info
  DocumentRoot /var/www/html

  <Directory /var/www/html/>
      Options -Indexes +FollowSymLinks
      AllowOverride All
  </Directory>

  ErrorLog /var/log/httpd/blog.domainhere.info-error.log
  CustomLog /var/log/httpd/blog.domainhere.info-access.log combined
  </VirtualHost>

Change blog.domainhere.info with Your Domain Name.

Now, restart & check the apache with the following commands:

systemctl restart httpd

systemctl status httpd

Enable Firewall:

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

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

firewall-cmd --reload

Generating Let's Encrypt SSL

Generate Let's Encrypt SSL with the following command.

certbot --apache

Output:

[root@vps ~]# certbot --apache
Saving debug log to /var/log/letsencrypt/letsencrypt.log
