    Hello everyone!
    I am currently looking into the vast FOG Installation scripts and I am attempting to find a way to automate the installation of FOG Servers with the exact same configurations. (Not Storage Nodes)

    Scenario: Include FOG as a default install option in a custom Ubuntu Server ISO. It must install automatically without needing user input. Everything in my ISO works perfectly, but I cannot find a way to make the FOG Installation scripts “Static”.

    What I’ve Tried:
    Setting Static Variables within the scripts,
    Manual Expect Script
    AutoExpect Scripts
    xdotool
    Piping answers “via TXT file, and execution command”
    (Probably more, but I don’t remember at this point.)

    Any help would be much appreciated! Thank you.

      @TBuzaTechnician Have you tried running the installer like this yet? ./installfog.sh -y

      This will just run through using all settings as default. If you need to modify specific settings there are command line switches for a lot of things and we could even add more if there is need to. Just run ./installfog.sh --help to show the command line switches. Be aware, there is an issue with the long form command line switches like --ssl-path ... - they simply don’t work but the short form -c ... should do.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

      Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

        @TBuzaTechnician By the way, we use this so called auto answer mode of the installer too. Thanks to @Wayne-Workman we have an automated installer test running: http://fogtesting.theworkmans.us/

        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          @Sebastian-Roth Thanks for the help! I will give it a try. I Know a few of the defaults are include things I want to avoid. Like using the FOG DHCP service.

            @TBuzaTechnician The default is to not make FOG the DHCP…

              Hello!

              Thanks for the help. Just in case someone has a similar scenario… You can find what I did below.

              Here I modified the initial values to what I needed. This seemed to have made sure that the values I entered were the settings to be used when installed. After doing this, I ran with the -y switch and without, and both seemed to work fine.

              \fogproject-1.5.7\bin\installfog.sh (Lines 351 - 371)

              [[ -z $dnsaddress ]] && dnsaddress=""
              [[ -z $username ]] && username=""
              [[ -z $password ]] && password=""
              [[ -z $osid ]] && osid=""
              [[ -z $osname ]] && osname=""
              [[ -z $dodhcp ]] && dodhcp=""
              [[ -z $bldhcp ]] && bldhcp=""
              [[ -z $installtype ]] && installtype=""
              [[ -z $interface ]] && interface=""
              [[ -z $ipaddress  ]] && ipaddress=""
              [[ -z $hostname  ]] && hostname=""
              [[ -z $routeraddress ]] && routeraddress=""
              [[ -z $plainrouter ]] && plainrouter=""
              [[ -z $blexports ]] && blexports=1
              [[ -z $installlang ]] && installlang=0
              [[ -z $bluseralreadyexists ]] && bluseralreadyexists=0
              [[ -z $guessdefaults ]] && guessdefaults=1
              [[ -z $doupdate ]] && doupdate=1
              [[ -z $ignorehtmldoc ]] && ignorehtmldoc=0
              [[ -z $httpproto ]] && httpproto="http"
              [[ -z $fogpriorconfig ]] && fogpriorconfig="$fogprogramdir/.fogsettings"
              

              Again, thank you for the help!

                @TBuzaTechnician You can also pre-place your .fogsettings file, rather than modifying the source code every time. Here’s a writeup on that settings file:
                https://wiki.fogproject.org/wiki/index.php?title=.fogsettings
                Modifying the source is cool too, whatever shakes your feathers.

                Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                  @Wayne-Workman Thanks for the info. I did modify the .fogsettings file at first, but I was receiving errors for “invalid response” whenever I attempted to install. I just copied the .fogsettings from a working installation.
