How to install Let’s Encrypt in Plesk
- Log in to Plesk and install the Let’s Encrypt extension via the Extension Catalog:
- After the installation, run a shell script. It fetches dependencies (sets up repositories and installs missing packages). Then it create virtual environment and installs the Let’s Encrypt console client with the Plesk plugin inside.
- Next, click the installed extension, select a website and install the certificate.
If you have already used the CLI client, you will recognize the interactive mode dialog in this web form. On a “success” message, follow the link to open the website and see the green “https” icon in the address bar.
- Check that the certificate renewal task has been added to Tools & Settings > Scheduled tasks:
Issued certificates are valid for 90 days, but according to the recommendation of the Let’s Encrypt developers, they are renewed on a monthly basis.
