Silent install Qt run installer on ubuntu server

问题:

I wanted to know if there is a way to do a silent install of the Qt run installer on Ubuntu Server?
I mean by-pass the options of the installer and do a default install?

The Qt toolkit is packaged using the Qt Installer Framework (QtIFW). QtIFW installers support a --script option that allows you to programatically control the installation via the Controller Scripting API. Here's qt-installer-noninteractive.qs file to install Qt 5 non-interactively:

// Emacs mode hint: -*- mode: JavaScript -*-

function Controller() {
    installer.autoRejectMessageBoxes();
    installer.installationFinished.connect(function() {
        gui.clickButton(buttons.NextButton);
    })
}

Controller.prototype.WelcomePageCallback = function() {
    // click delay here because the next button is initially disabled for ~1 second
    gui.clickButton(buttons.NextButton, 3000);
}

Controller.prototype.CredentialsPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.IntroductionPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.TargetDirectoryPageCallback = function()
{
    gui.currentPageWidget().TargetDirectoryLineEdit.setText(installer.value("HomeDir") + "/Qt");
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.ComponentSelectionPageCallback = function() {
    var widget = gui.currentPageWidget();

    widget.deselectAll();
    widget.selectComponent("qt.55.gcc_64");
    widget.selectComponent("qt.55.qtquickcontrols");

    // widget.deselectComponent("qt.tools.qtcreator");
    // widget.deselectComponent("qt.55.qt3d");
    // widget.deselectComponent("qt.55.qtcanvas3d");
    // widget.deselectComponent("qt.55.qtlocation");
    // widget.deselectComponent("qt.55.qtquick1");
    // widget.deselectComponent("qt.55.qtscript");
    // widget.deselectComponent("qt.55.qtwebengine");
    // widget.deselectComponent("qt.extras");
    // widget.deselectComponent("qt.tools.doc");
    // widget.deselectComponent("qt.tools.examples");

    gui.clickButton(buttons.NextButton);
}

Controller.prototype.LicenseAgreementPageCallback = function() {
    gui.currentPageWidget().AcceptLicenseRadioButton.setChecked(true);
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.StartMenuDirectoryPageCallback = function() {
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.ReadyForInstallationPageCallback = function()
{
    gui.clickButton(buttons.NextButton);
}

Controller.prototype.FinishedPageCallback = function() {
var checkBoxForm = gui.currentPageWidget().LaunchQtCreatorCheckBoxForm;
if (checkBoxForm && checkBoxForm.launchQtCreatorCheckBox) {
    checkBoxForm.launchQtCreatorCheckBox.checked = false;
}
    gui.clickButton(buttons.FinishButton);
}

This script demonstrates how to select/deselect certain components. Customize for your needs or just remove the lines entirely for a default installation. Likewise, you may want to customize or remove the TargetDirectoryLineEdit line. Run the Qt installer like:

qt-opensource-linux-x64-5.5.1.run --script qt-installer-noninteractive.qs

Add -platform minimal for a headless installation. Future installers based on newer versions of QtIFW should be able to use a --silent option instead (see QTIFW-166).

Add --verbose for more verbose console output (helpful for gleaning component names, wizard page names, etc). This link is also helpful for figuring out component names.

As of installer 3.0.2-online 29-11-2017, you must add a delay in your JS script because the "Next" button in the "Welcome" page is disabled for one second or so.

Controller.prototype.WelcomePageCallback = function() {
    gui.clickButton(buttons.NextButton, 3000);
}

There have few minor different in answering the questions of wizard for a different kind of version of Qt. To make it more simple, I have packed a generic script to extract Qt from an offline/online installer.

The script: qtci/extract-qt-installer at master · benlau/qtci

Example Usage:

extract-qt-installer qt-opensource-linux-x64-android-5.5.1.run ~/Qt

Environment Variables"

VERBOSE [Optional] Set to "true" will enable VERBOSE output
QT_CI_PAGEAGES [Optional] Select the components to be installed instead of using default (eg. QT_CI_PAGEAGES="qt.59.gcc_64")

Moreover, it has few scripts to download and install Qt with different versions.

I had the same problem and came up with a simple python script that basically does the same what the official Qt installer does. You can find it here.

And that's how to use it:

sudo apt install python3-requests p7zip-full wget

wget https://git.kaidan.im/lnj/qli-installer/raw/master/qli-installer.py
chmod +x qli-installer.py

./qli-installer.py 5.11.3 linux desktop

Then the Qt installation can be found at ./5.11.3/gcc_64/ in this case. With other systems/targets (i.e. mac ios or linux android android_armv7) this will differ of course.
