I think I have the right OpenSSL command to sign a certificate but I\'ve gotten stuck and the tutorials I\'ve found use a different argument format (I\'m using OpenSSL 0.9.8o 01
Based on snow6oy's answer, here's what I did:
openssl x509 -req -CA CACert.pem -CAkey CAKey.pem -CAcreateserial -in YourCSR.csr -out YourCert.pem
A couple optional flags that may be useful:
-days 1095 (The default is 30 days)
-days 1095
-sha256 (RHEL 7 defaults to SHA-1)
-sha256
