Adding a cert to the cert store

RHEL based distributions

# cp cert-chain.crt /etc/pki/ca-trust/source/anchors/
# update-ca-trust

Ubuntu (and maybe other Debian derivatives)

Make sure the file has a .crt extension. It won’t work with .pem for some reason.

# apt-get install -y ca-certificates
# cp CERT-FILE.pem /usr/local/share/ca-certificates
# update-ca-certificates
