pass argument to installer via bash

Question

I'm trying to do an unattended install of phpmyadmin however during the install it prompts you to select which web server your using ie apache or lighttpd what i'd like to do is pass the lighttpd value automatically ie

apt-get install phpmyadmin &value lighttpd

Answer 1

You can use echo with pipe:

echo "lightttpd" | apt-get install phpmyadmin

Answer 2

I installed phpmyadmin

apt-get install phpmyadmin

Then used conf-selections to return the values

sudo debconf-get-selections | grep phpmyadmin | grep lighttpd

Which returned

phpmyadmin      phpmyadmin/reconfigure-webserver        multiselect     lighttpd

So in my script I had

#!/bin/bash
echo "phpmyadmin phpmyadmin/reconfigure-webserver multiselect lighttpd" | debconf-set-selections
apt-get install -y phpmyadmin

Ran it and it no longer prompted for that value.
