Configure Mysql 5.7 with Travis CI

Question

I can't run my tests on Travis CI because i can't find a way to setup mysql 5.7 in container.

I've found this gist https://gist.github.com/BenMorel/d981f25ead0926a0cb6d explaining a configuration method for travis.yml. Here are the commands :

sudo apt-get remove --purge "^mysql.*"
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /var/lib/mysql
sudo rm -rf /var/log/mysql
echo mysql-apt-config mysql-apt-config/enable-repo select mysql-5.7-dmr | sudo debconf-set-selections
wget http://dev.mysql.com/get/mysql-apt-config_0.2.1-1ubuntu12.04_all.deb
sudo dpkg --install mysql-apt-config_0.2.1-1ubuntu12.04_all.deb
sudo apt-get update -q
sudo apt-get install -q -y -o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold" mysql-server

right after that, I'm doing :

$ mysql -uroot < tests/ApiBundle/Datas/dump_test.sql
ERROR 1698 (28000): Access denied for user 'root'@'localhost'

Why ?? I've tried so many things… And Google is definitely not my friend for this issue…

Ok I've found out how to reinstall MySQL 5.6 in Travis CI default container.

Here is what is needed in .travis.yml:

services:
  - mysql
sudo: true
before_script:
  - bash .travis.install-mysql-5.7.sh

And here is the .travis.install-mysql-5.7.sh (edited thanks to @codyzu answer):

echo mysql-apt-config mysql-apt-config/select-server select mysql-5.7 | sudo debconf-set-selections
wget https://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
sudo dpkg --install mysql-apt-config_0.7.3-1_all.deb
sudo apt-get update -q
sudo apt-get install -q -y --allow-unauthenticated -o Dpkg::Options::=--force-confnew mysql-server
sudo mysql_upgrade

I hope it would help anyone facing the same issue !
