- # touch /etc/pki/CA/serial
- # echo 01 > serial
- Copy the existing openssl.cnf to the Certificate Authority directory.
- # cp /etc/pki/tls/openssl.cnf /etc/pki/CA/.
- Generate the CA Private Key and CA Certificate:
- # cd /etc/pki/CA/
- # mkdir private
- # openssl req -config openssl.cnf -new -x509 -extensions v3_ca -keyout private/cakey.pem -out cacert.pem -days 36525
- To sign a CSR.
- Upload the <certificate signing request>.csr to /etc/pki/CA/csrs/.
- # cd /etc/pki/CA
- # openssl ca -config openssl.cnf -policy policy_anything -out certs/<certificate>.crt -infiles csrs/<certificate signing request>.csr
