You are here:
< All Topics

LetsEncrypt is a certificates authority that gives free SSL/TLS certificates for an internet server. It supplies a free TLS encryption utilizing an automatic course of. Normally enabling SSL is a posh course of which requires guide creation, validation, signing, set up, and renewal of certificates with the intention to attain a safe non-public related web site. The automated course of eliminates the necessity for the aforementioned steps. Additionally, LetsEncrypt is supported by all main net browsers. This tutorial describes LetsEncrypt assist on a DirectAdmin net server. LetsEncrypt assist is a built-in characteristic or is obtainable natively since DirectAdmin model 1.50. Help can both be simply built-in or might be enabled by manually logging in to the server through SSH for older variations.


Enabling as a built-in characteristic

1) First, replace DirectAdmin management panel and the server for the newest variations.

2) Execute a particular command for altering the DirectAdmin configuration file to allow LetsEncrypt. This can be manually executed by modifying the configuration file /usr/native/directadmin/conf/directadmin.conf. By altering the worth zero to 1 it allows LetsEncrypt software program.

The command for doing that is as beneath.

$ grep -q ‘letsencrypt=1’ /usr/native/directadmin/conf/directadmin.conf || echo ‘letsencrypt=1’ >> /usr/native/directadmin/conf/directadmin.conf

For permitting a number of SSL enabled websites on single IP handle SNI assist of TLS protocol should be enabled within the server. The command beneath is used to allow SNI

$ grep -q ‘enable_ssl_sni=1’ /usr/native/directadmin/conf/directadmin.conf ||echo ‘enable_ssl_sni=1’ >>/usr/native/directadmin/conf/directadmin.conf


3) After altering the configuration file, we now have to restart DirectAdmin.

4) Help is enabled and the following step is to provision the certificates. Login with the person for whom we have to request the certificates for and navigate to Superior Options >> SSL certificates.

5) Select the third choice, “Free & computerized certificates” from Let’s Encrypt and fill within the fields. It would allow the SSL certificates and can obtain the quote “Certificates and Key Saved” with certificates particulars.


Enabling manually

It’s important to SSH to the server and set up the Git Clone LetsEncrypt code to the server. This may be executed by utilizing the instructions beneath.

$ git clone https://github.com/letsencrypt/letsencrypt

$ cd letsencrypt

You must present your Webroot path. The consumer locations the authentication problem information there to do the precise certificates area possession validation. You will discover that in your webserver configuration. For DirectAdmin it’s like this: /dwelling/USERNAME/domains/DOMAIN.EXT/public_html.

Now execute the LetsEncrypt command to get the certificates.

$ ./letsencrypt-auto –server https://acme-01.api.letsencrypt.org/listing certonly –agree-tos –e-mail ‘person@area.tld’ –webroot –webroot-path ‘/dwelling/USERNAME/domains/DOMAIN.COM/public_html/’ -d area.com -d www.area.com

For those who want a certificates with a number of subdomains or with www.area.tld and area.tld, specify the -d area choice a number of instances. Be sure that the Webroot is identical. For those who solely want one area, change the instance and take away the final -d choice. The consumer will then do a bit of labor with the LetsEncrypt service to validate area possession. If all goes properly it would print out the beneath message:

Model: 1.1-20080819

Model: 1.1-20080819


– Congratulations! Your certificates and chain have been saved at

/and so on/letsencrypt/reside/DOMAIN.COM/fullchain.pem. Your cert

will expire on 2017-03-31. To acquire a brand new model of the

certificates sooner or later, merely run Let’s Encrypt once more.

$ ls -la /and so on/letsencrypt/reside/DOMAIN.COM/


Get the contents of the certificates, non-public key and chain with the next instructions. Keep in mind to switch certificatemonitor.org together with your area:

$ cat /and so on/letsencrypt/reside/certificatemonitor.org/cert.pem

$ cat /and so on/letsencrypt/reside/certificatemonitor.org/privkey.pem

$ cat /and so on/letsencrypt/reside/certificatemonitor.org/chain.pem


After you’ve put in the certificates within the management panel (DirectAdmin), we have to symlink these information to the LetsEncrypt information in order that auto renewal will work. We do must first set up them through the management panel in order that the configuration will get up to date within the right method. Most management panels overwrite guide adjustments. Login to your DirectAdmin management panel and navigate to your web site. Beneath “Superior Options” click on “SSL Certificates”. Choose the radio button for the Paste a pre-generated certificates and key choice. Within the textual content discipline beneath, first paste the contents of the cert.pem file. Under that, paste the contents of the privkey.pem file.




Click on the Save button. Now return to the principle area display, and navigate to “Superior Options” –> “SSL Certificates” once more. Scroll down and open the hyperlink Click on Right here to stick a CA Root Certificates. Mark the checkbox Use a CA Cert. Paste the contents of the chain.pem file there. Click on the Save button. For those who haven’t already enabled SSL on your area, try this now. Navigate to the principle area display. Click on “Area Setup”. Open your area. Mark the Safe SSL checkbox and click on the save button. Now, below private_html setup for DOMAIN.COM – (SSL should be enabled above) mark the radio button. Use a symbolic hyperlink from private_html to public_html – permits for identical knowledge in http and https and click on the save button once more. Now navigate to https://yourdomain and confirm the certificates.
