AutoInstall SSL Tutorials

AutoInstall SSL is an agent that runs on your web server and handles the whole life of an SSL certificate: it creates the key and CSR, validates the domain, installs the certificate and replaces it before it expires. It comes with SSL Dragon’s RapidSSL and GeoTrust automation plans and needs root or administrator access to the server. On cPanel or Plesk, use our ACME tutorials instead. Pick the guide for your server below.

How to Install an SSL Certificate on Linux with AutoInstall SSL (Apache and NGINX)

For Apache and NGINX on Ubuntu, Debian, CentOS Stream, Rocky Linux and AlmaLinux. You run both commands over SSH with sudo. The agent adds HTTPS to your existing site configuration, tests it and reloads the web server only if the test passes. Renewals run from a cron job that checks the certificate twice a day. Also covers DNS validation for wildcard plans and fixes for errors such as “Main domain binding not found”.
