mysql_secure_installation requires an interactive session. 

A unatteded/silent install should be possible.

How to repeat:
Try to run mysql_secure_installation from a script.

Suggested fix:
This fix is NOT yet complete as set_root_password still asks questions.

This workaround could be used:

#!/usr/bin/expect --
spawn /usr/local/mysql/bin/mysql_secure_installation

expect "Enter current password for root (enter for none):"
send "\r"
expect "Set root password?"
send "y\r"

expect "New password:"
send "password\r"

expect "Re-enter new password:"
send "password\r"

expect "Remove anonymous users?"
send "y\r"

expect "Disallow root login remotely?"
send "y\r"

expect "Remove test database and access to it?"
send "y\r"

expect "Reload privilege tables now?"
send "y\r"

puts "Ended expect script."

We believe this was taken care of in 5.6.8 through the --random-passwords option to mysql_install_db:

Actually, the changes to mysql_install_db do *not* resolve the issues described here. It's still not possible to run mysql_secure_installation in an unattended fashion.

Please change the status to Open or Verified per the comment from Lenz. I can't change it myself as this bug was filed with my previous account.
