I want a bash script that installs a MySQL 5.7 instance without needing any manual input.
I was following the tutorial on Digital Ocean and it says for 5.7 you have to run the following commands and then put commands into a prompt (screenshot below).
wget http://dev.mysql.com/get/mysql-apt-config_0.6.0-1_all.deb sudo dpkg -i mysql-apt-config_0.6.0-1_all.deb
How can I automate the installation if it requires me to use a prompt? Should I try to simulate keystrokes? Or am I going about it the wrong way?

Answer
This answer is a combination and alteration of Bimmy’s and khrm’s answers.
STEP 1:
You have to set debconf values which will automatically fill in the values prompted for by the installation.
export DEBIAN_FRONTEND="noninteractive"
sudo debconf-set-selections <<< "mysql-server mysql-server/root_password password rootpw"
sudo debconf-set-selections <<< "mysql-server mysql-server/root_password_again password rootpw"
To get the values you need, just run installation normally, a good tutorial of it is here
STEP 2:
Update the information needed for APT by adding the 5.7 repository and updating `apt-get
sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 5072E1F5
cat <<- EOF > /etc/apt/sources.list.d/mysql.list
deb http://repo.mysql.com/apt/ubuntu/ trusty mysql-5.7
EOF
sudo apt-get update
STEP 3:
Install MySQL. You can run my mysql_secure_installation but then that will ask you for more prompts. mysql_secure_installation is just a script so if you want to you can just run the parts of that script which are relevant to you.
I just ran
sudo apt-get install -y mysql-server-5.7 on its own.
