how to install certbot centos 8

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

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:

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:

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:

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.
