Everytime Apache is started up, one will be asked for their pass phrase. This not necessarily convenient, as someone will have to be around everytime Apache is started up. Supposing the server is rebooted for whatever reason - Apache will have to be restarted manually. To get around this, one can create a Server Key, just like the sectiona above showed, however, Openssl will not ask for a pass phrase. This way, the pass phrase will not need to entered upon every Apache startup.
# openssl genrsa 1024 > server.key
One must make sure the server.key is only readable by the root user.
