sudo yum -y install certbot python2-certbot-nginx nginx
Run the command as shown below to request SSL for *.yourdomain.id.
sudo certbot certonly \ --agree-tos \ --email [email protected] \ --manual \ --preferred-challenges=dns \ -d *.yourdomain.id \ --server https://acme-v02.api.letsencrypt.org/directory
Once you execute the command, you will receive a TXT record which you need to add to your DNS server. The records will look as below:
Please deploy a DNS TXT record under the name _acme-challenge.yourdomain.id with the following value: 7qx8FNyWnK_HENpP6xqq3_Vl6Ful7hiVTVLKZafp8p8 Before continuing, verify the record is deployed.
Add the records to your DNS server for the webserver domain.
host -t txt _acme-challenge.example.com
Once you have verified that the record has been deployed, press Enter to obtain the SSL. You should get feedback as below:
