Often times you may need to have your internal systems have a non-public root certificate installed, from an internal CA. These are a few steps on how to add that root certificate.
Linux (CentOS 6)
- Install the ca-certificates package from yum.
1sudo yum install ca-certificates - Enable the ability to dynamically update CA Trusts
1sudo update-ca-trust force-enable - Add your certs to /etc/pki/ca-trust/source/anchors/
1sudo cp *.crt /etc/pki/ca-trust/source/anchors/ - Update your CA Trusts
1sudo update-ca-trust extract
Linux (CentOS 7)
- Copy your root certificate to /etc/pki/ca-trust/source/anchors/
1sudo cp *.crt /etc/pki/ca-trust/source/anchors/ - Update your CA Trusts
1sudo update-ca-trust extract
