Letsencrypt (Certbot) Generate The Wildcard SSL Certificate

Posted on | by @thinkcyber | Leave a Comment on Letsencrypt (Certbot) Generate The Wildcard SSL Certificate

Now with the help of Certbot will generate wildcard certificate for our test domain erpnext.xyz

sudo certbot certonly --manual --preferred-challenges=dns --email nome@erpnext.xyz --server https://acme-v02.api.letsencrypt.org/directory --agree-tos -d *.erpnext.xyz

After executing the above command, the Certbot will share a text record to add to your DNS.


Please deploy a DNS TXT record under the name
_acme-challenge.erpnext.xyz with the following value:

J50GNXkhGmKCfn-0LQJcknVGtPEAQ_U_WajcLXgqWqo

Then you will receive:

Press Enter to Continue
Waiting for verification...
Cleaning up challenges

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/erpnext.xyz-0001/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/erpnext.xyz-0001/privkey.pem
  Your cert will expire on 2019-08-31. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot
   again. To non-interactively renew *all* of your certificates, run
   "certbot renew"

Check version number

certbot --version || /path/to/certbot-auto --version

If you have already installed Certbot, you should add a parameter to apt-get install to upgrade only a specific package

sudo apt-get update
sudo apt-get install --only-upgrade certbot

Letsencrypt Combining plugins

Combining plugins

Sometimes you may want to specify a combination of distinct authenticator and installer plugins. To do so, specify the authenticator plugin with --authenticator or -a and the installer plugin with --installer or -i.

For instance, you could create a certificate using the webroot plugin for authentication and the apache plugin for installation.

certbot run -a webroot -i apache -w /var/www/html -d example.com
