Question

Where do the Let's Encrypt and SSL It! extensions for Plesk keep all .pem files for certificates, full chains and private keys of Let's Encrypt certificates on a file system?

Answer

Plesk on Linux


On Linux systems, the .pem files are located in these directories:

For the Let's Encrypt extension -  /usr/local/psa/var/modules/letsencrypt/etc/archive/example.com/

For the SSL It! extension - /usr/local/psa/var/modules/sslit/etc/archive/example.com/

The contents of this directory would be similar to the following:

# root@server:/usr/local/psa/var/modules/sslit/etc/archive/example.com# ls -alh
total 92K
drwx------ 2 psaadm psaadm 4.0K Sep 9 17:56 .

-rw-r--r-- 1 psaadm psaadm 3.6K Jul 11 17:56 fullchain4.pem
-rw-r--r-- 1 psaadm psaadm 3.6K Sep 9 17:56 fullchain5.pem
-rw-r--r-- 1 psaadm psaadm 1.7K Jan 13 2024 privkey1.pem
-rw-r--r-- 1 psaadm psaadm 1.7K Mar 13 2024 privkey2.pem
-rw-r--r-- 1 psaadm psaadm 1.7K May 12 17:56 privkey3.pem
-rw-r--r-- 1 psaadm psaadm 1.7K Jul 11 17:56 privkey4.pem
-rw-r--r-- 1 psaadm psaadm 1.7K Sep 9 17:56 privkey5.pem

Plesk on Windows


On Windows systems, the .pem files are located in these directories:

For Let's Encrypt extension -  %plesk_dir%var\modules\letsencrypt\etc\archive\example.com\.

For SSL It! extension - %plesk_dir%var\modules\sslit\etc\archive\example.com\

    I've migrated from Ubuntu 18.04 Plesk server to 22.04 Plesk server using Migrator. Let's Encrypt certificates was migrated, but there are no folders with .pem files as described. Where are the files now? I only have found one folder of my three domains, and under live folder, not at archive folder. What are the difference between archive and live folders?
