how to install certbot centos 8

2 Answer(s)

To add the CentOS 8 EPEL repository, run the following command:

  • sudo dnf install epel-release
Now that you have access to the repository, install all of the required packages:
  • sudo dnf install certbot python3-certbot-apache mod_ssl
With these services installed, you’re now ready to run Certbot and fetch your certificates.

Step 2 — Obtaining a Certificate

Now that Certbot is installed, you can use it to request an SSL certificate for your domain.

Using the certbot Let’s Encrypt client to generate the SSL Certificate for Apache automates many of the steps in the process. The client will automatically obtain and install a new SSL certificate that is valid for the domains you provide as parameters.

To execute the interactive installation and obtain a certificate that covers only a single domain, run the certbot command with:

  • sudo certbot –apache -d example.com
This runs certbot with the --apache plugin and specifies the domain to configure the certificate for with the -d flag.

If you want to install a single certificate that is valid for multiple domains or subdomains, you can pass them as additional parameters to the command, tagging each new domain or subdomain with the -d flag. The first domain name in the list of parameters will be the base domain used by Let’s Encrypt to create the certificate. For this reason, pass the base domain name as first in the list, followed by any additional subdomains or aliases:

  • sudo certbot –apache -d example.com -d www.example.com
The base domain in this example is example.com.

The certbot utility can also prompt you to choose a domain based on your existing Apache configuration. To use this functionality, call certbot without any domains specified:

  • sudo certbot –apache
The program will present you with a step-by-step guide to customize your certificate options. It will ask you to provide an email address for lost key recovery and notices, and then prompt you to agree to the terms of service. If you did not specify your domains on the command line, you will be prompted for that as well. If your Virtual Host files do not specify the domain they serve explicitly using the ServerName directive, you will be asked to choose the virtual host file.

When the installation is successfully finished, you will see a message similar to this:

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/example.com/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/example.com/privkey.pem
   Your cert will expire on 2020-09-24. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

The generated certificate files will be available within a subdirectory named after your base domain in the /etc/letsencrypt/live directory.

Now that your certificates are downloaded, installed, and loaded, you can check your SSL certificate status to make sure that everything is working.
