Importing ca-certificate chain (.crt) - RHEL7

Solution 1:

I appears by including the ca-cert bundle in /etc/pki/ca-trust/source/ and running update-ca-trust extract worked fine.

Solution 2:

Copy the certificates to /etc/pki/ca-trust/source/anchors/ and after that execute update-ca-trust extract.

They should be available to all application that check that path for certificates (for example wget and curl).
