1.You first need to order an SSL, for example at
ispsystem.com.
When you get the certificate, you will need its private key (it can be kept in the Client area where you order the ssl) and archive (it will be sent by the Certification authority).
2. Log in to ISPmanager as user who own the WWW-domain -- SSL-certificates -- click "Add" -- type "Existing".
Name - Enter any name you like.
SSL-certificate - add the contents of the
.crt file from the archive (including -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----).
Add contents of the
private key into the
corresponding field. SSL chain can be taken from
.ca-bundle.
3. Next, navigate to ISPmanager - WWW-domains -- Edit -- check the SSL box and in the list that will open select the SSL certificate you have just added.
