One way would be to specify the password afterwards (when you know the default)
mysqladmin -u root password <NEW_PASS>
You can try to make that part of your script.
The other way would be to use here-strings.
It will basically look something like this:
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password password <NEW_PASS>'
sudo debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password <NEW_PASS>'
sudo apt-get -y install mysql-server
Third way would be to use a real provisioning framework like Chef or Puppet or other, where you use files to describe a certain type of node, similar to this:
class mysql-server {
$password = "insert_password_here"
package { "MySQL-client": ensure => installed }
package { "MySQL-server": ensure => installed }
package { "MySQL-shared": ensure => installed }
exec { "Set MySQL server root password":
subscribe => [ Package["MySQL-server"], Package["MySQL-client"], Package["MySQL-shared"] ],
refreshonly => true,
unless => "mysqladmin -uroot -p$password status",
path => "/bin:/usr/bin",
command => "mysqladmin -uroot password $password",
}
}
