Hi Guys,

Im using ubuntu 20 and apache 2.4, i need to install ssl certifcate. I got 2 file in .pem format.

gazda.or.pem - certificate
DigiCert-TLS-RSA-SHA256-2020-CA1.pem - i think this is key.

What is the correct procedure for installing certificates? The first time I install pem files.

I found a /etc/apache2/sites-available default-ssl.conf file where i can add certificate file but regulary its was in .crt format and .key.

Somebody can help me?

Hi @gazdamoldova,

You need to add the files on your system, where ever you want but I’ll suggest using the /etc/apache2/ssl/ directory.

In there add the files. I don’t think the extension matters, what it matters is typing the proper file to the proper option in :


You are right, they are a strange format but by opening them, you should be able to see what’s what. Add them to the above options accordingly and restart Apache. You’ll see if something went wrong, if it did, it’s just trial and error afterwards.
