Worked Excellently!!! My notes / suggestions: 1.) add a note to use to linux command 'hostnamectl set-hostname server1.example.com', prior to running script, because a FQDN is necessary... I reset my server, so was on the default alibaba hostname at the time I made my first attempt to run the autoinstaller. 2.) I did get one warning during the setup process regarding the resolver, see screenshot: https://i.imgur.com/WzuTTwz.png Code: [WARN] Unexpected resolver response: Server: 100.100.2.136 (/lib/os/class.ISPConfigDebianOS.inc.php:869) 3.) SSL seems to work despite the warning, no browser warning about SSL at the login page 4.) About the final line of the installer, the warning about the passwords, my suggestion is this: Yours: [INFO] Warning: Please delete the log files in /tmp/ispconfig-ai/var/log/setup-* once you don't need them anymore because they contain your passwords! Mine: [INFO] Warning: AFTER you have copied the default passwords to a safe location, please delete the temporary setup files, run ' /tmp/ispconfig-ai/var/log/setup-* '. You can change your default passwords via the ISPConfig interface. Happy Hosting! 5.) Provide means to change default passwords via ISPConfig or in the short run provide a link to instructions to change the default passwords. Default, unchangeable passwords, make paranoid people, more paranoid.
