Don't know what's going on on your system.
Maybe it helps if you uninstall ISPConfig (run /root/ispconfig/uninstall
) and then install ISPConfig again, but this time you should choose http instead of https in the installer; also have a look at http://www.ispconfig.org/manual_installation.htm
. It says:
In step 7 ("Encrypting RSA private key of CA with a pass phrase for security [ca.key]")and step 8 ("Encrypting RSA private key of SERVER with a pass phrase for security [server.key]") of the certificate creation process you are asked if you want to encrypt the respective key now. Choose n there because otherwise you will always be asked for a password whenever you want to restart the ISPConfig system which means it cannot be restarted without human interaction!
