DirectAdmin has a nice script that will install free Let’s Encrypt SSL certificates for all the domains on the server that do not have a valid one. The commands to download, set the needed permission and execute the script are:
# wget -O autoletsencrypt.sh http://files.directadmin.com/services/all/letsencrypt/autoletsencrypt.sh
# chmod 755 autoletsencrypt.sh
# ./autoletsencrypt.shExemple output for our test server is:
[root@web21 ~]# wget -O autoletsencrypt.sh http://files.directadmin.com/services/all/letsencrypt/autoletsencrypt.sh

[root@web21 ~]#Please notice that the script will take some time to run if you have many domains on your server that require new certificates.
Notice that you can install individual Let’s Encrypt SSL certificates via the DirectAdmin GUI. Check our article on How to install Let’s Encrypt SSL certificate in DirectAdmin.
