When Apache started it prompted for the pass phrase. So Server rebooted that apache can't auto start.
This Problem, I resolved by created rsa key file
# cp ssl.key/server.key ssl.key/server.key.org
# openssl rsa -in ssl.key/server.key.org -out ssl.key/server.key
# chmod 400 ssl.key/server.key
The new ssl.key/server.key above is insecure; I protected it by setting the permissions on the file as restrictively as possible.
