Installing the necessary Python module:įor "Let's Encrypt" certificates to work properly we have to add "localhost" nameserver. "Git" package installed (yum install git -y).Ģ. "Webmin 1.9 with CentOS 7" template installed on the server įully updates server software (yum update) The tutorial was prepared with our "Webmin 1.9 with CentOS 7" template and is meant to work on our self-managed virtual private servers. In this tutorial, you will find out how you can benefit from these certificates by providing security for your Webmin websites. Let’s Encrypt is a service provided by the Internet Security Research Group (ISRG). To use the new cert in Usermin, go to Webmin -> Webmin -> Usermin Configuration -> Current Certificate, and hit Copy Certificate from Webmin to copy the SSL certificate, private key, CA cert and other settings that Webmin is using.Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. Also ensure that Copy new key and certificate to Webmin? option is set to Yes to use the newly created cert in Webmin. The screen is similar to how you generate the Let’s Encrypt cert for virtual host, where hostnames for certificate is automatically detected by Webmin and you can add more, except that you may need to specify the w ebsite root directory for validation file as the domain name of Webmin and Usermin root may not be accessible via A record in DNS. Go to Webmin -> Webmin -> Webmin Configuration -> SSL Encryption. Webmin has another way to request and generate Let’s Encrypt cert to secure Webmin, useful if your Webmin and Usermin root is in a sub-domain which requires SSL certificate of their own. Unless the SSL certificate has included the domain name which Webmin and Usermin is running on, you need not copy the Let’s Encrypt cert used in Virtual Server toĪlternative to Secure Webmin and Usermin Using Let’s Encrypt ![]() Under Permanent URL redirects, enter / (slash) for From textbox, and (your website URL with HTTPS in full) in To textbox. To do so (make sure the correct virtual server is still selected in Virtualmin), go to Services -> Configure Website (make sure that it’s NOT “Configure Website for SSL”). Redirecting HTTP Web Traffic to HTTPS SSL ConnectionĪfter enabling the SSL, you may want to ask web server to automatically redirect all HTTP connections to HTTPS connections for the domain. Virtualmin has built-in capability to set this up. You can now visit your website via HTTPS secure connection, which should automatically trusted by most web browsers, and see it protected with a padlock. Once done, Virtualmin will automatically install SSL certificate and configure the web server to use the new certificate and key. ![]() So you have to renew the SSL cert before 3 months is up to ensure the HTTPS visits to to your websites are uninterrupted. Let’s Encrypt SSL certificate has the lifetime of only 90 days before its expiry.
