How to install a CA certificate on Red Hat Enterprise Linux 7 and later?

Issue

• I purchased a SSL certicate and I have the CA bundle but when I try to run the following command it fails with the error below. How do I install the certificate?

  # openssl verify server.crt
  server.crt: C = US, O = GeoTrust Inc., CN = GeoTrust Global CA
  error 2 at 2 depth lookup:unable to get issuer certificate
  
  # openssl verify -CAfile rapidSSL-ca.crt server.crt 
  OK
