Let\u2019s Encrypt<\/a> is a service offering free SSL certificates through an automated API. The most popular Let\u2019s Encrypt client is EFF<\/a>\u2019s Certbot<\/a>. And we gan get certificate for all propose mostly for testing but it can be also for production environment. if you have web server on the server you can just execute the Certbot for every scenario and you will get the cert automatically :<\/p>\n\n\n\n

https:\/\/certbot.eff.org\/instructions?<\/a><\/pre>\n\n\n\n
But to get Certificate without web server you will need to valid your domain with DNS Text keys , first install Certbot :<\/p>\n\n\n\n
yum install certbot<\/code><\/pre>\n\n\n\n
Now you will be able to execute requests with Certbot, for example to get certificate to webserver  :<\/p>\n\n\n\n
certbot certonly --standalone  --preferred-challenges dns --debug-challenges -d \\sub_domain.your_domain_name -d your_domain_name<\/pre>\n\n\n\n
So to get certificate to www.example.com :<\/p>\n\n\n\n
certbot certonly --standalone  --preferred-challenges dns --debug-challenges -d \\www.example.com -d example.com<\/pre>\n\n\n\n
You will need to create DNS TXT record with to keys that will be provided during the wizrad <\/p>\n\n\n\n
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nPlease deploy a DNS TXT record under the name:\n\n_acme-challenge.example.\n\nwith the following value:\n\nEjgxncutdNPNw_A71Oqc3dCYrgBCqXjmTwBLIC_iAb8\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nPress Enter to Continue\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nPlease deploy a DNS TXT record under the name:\n\n_acme-challenge.example.com\n\nwith the following value:\n\nvPhEwjMg3C4j-N-UF8DyFzR5hVV2OONgvpNYzILJAbU\n\n(This must be set up in addition to the previous challenges; do not remove,\nreplace, or undo the previous challenge tasks yet. Note that you might be\nasked to create multiple distinct TXT records with the same name. This is\npermitted by DNS standards.)\n\nBefore continuing, verify the TXT record has been deployed. Depending on the DNS\nprovider, this may take some time, from a few seconds to multiple minutes. You can\ncheck if it has finished deploying with aid of online tools, such as the Google\nAdmin Toolbox: https:\/\/toolbox.googleapps.com\/apps\/dig\/#TXT\/_acme-challenge.g-cloud.co.il.\nLook for one or more bolded line(s) below the line ';ANSWER'. It should show the\nvalue(s) you've just added.\n<\/pre>\n\n\n\n
After setting the DNS records you will get the certificate to the folder :<\/p>\n\n\n\n
...\nCongratulations! Your certificate and chain have been saved at:\n\/etc\/letsencrypt\/live\/your-domain\/fullchain.pem\nYour key file has been saved at:\n\/etc\/letsencrypt\/live\/your-domain\/privkey.pem\n...<\/pre>\n\n\n\n
Next you will need to give access permission to that folder :<\/p>\n\n\n\n
chmod +x \/etc\/letsencrypt\/live\n<\/pre>\n\n\n\n
In order to update the certificate you can run :<\/p>\n\n\n\n
certbot renew --dry-run\n<\/pre>\n\n\n\n
It should works but some time you will need to install the acme-dns-certbot<\/p>\n\n\n\n
