Install MySQL on Ubuntu without a password prompt

Question

How do I write a script to install MySQL server on Ubuntu?

sudo apt-get install mysql will install, but it will also ask for a password to be entered in

Answer 1

Another way to make it work:

echo "mysql-server-5.5 mysql-server/root_password password root" | debconf-set-selections
echo "mysql-server-5.5 mysql-server/root_password_again password root" | debconf-set-selections
apt-get -y install mysql-server-5.5

Note that this simply sets the password to "root". I could not get it to set a blank password using simple quotes '', but this solution was sufficient for me.
