This page provides instructions on installing Autolab for development on Ubuntu 18.04 LTS. If you encounter any issue along the way, check out Troubleshooting.
Upgrade system packages and installing prerequisites
sudo apt-get update sudo apt-get upgrade sudo apt-get install build-essential git libffi-dev zlib1g-dev autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev libncurses5-dev libgdbm5 libgdbm-dev libmysqlclient-dev libjansson-dev universal-ctags
Cloning Autolab repo from Github to ~/Autolab
cd ~/ git clone https://github.com/autolab/Autolab.git cd Autolab
Setting up rbenv and ruby-build plugin
cd ~/ git clone https://github.com/rbenv/rbenv.git ~/.rbenv echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc echo 'eval "$(rbenv init -)"' >> ~/.bashrc source ~/.bashrc ~/.rbenv/bin/rbenv init git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
Installing Ruby (Based on ruby version)
cd Autolab rbenv install `cat .ruby-version`
sudo apt-get install sqlite3 libsqlite3-dev
Installing MySQL. (If you would just like to test Autolab, then you can skip this step by using SQLite) Following instructions from How to Install MySQL on Ubuntu.
sudo apt install mysql-server sudo mysql_secure_installation > There will be a few questions asked during the MySQL setup. * Validate Password Plugin? N * Remove Annonymous Users? Y * Disallow Root Login Remotely? Y * Remove Test Database and Access to it? Y * Reload Privilege Tables Now? Y
(If you are using MySQL) Create a new user with access to
autolab_developmentdatabases. Because a password rather than auth_socket is needed, we need to ensure that user uses
sudo mysql mysql> CREATE USER 'user1'@'localhost' IDENTIFIED WITH mysql_native_password BY '<password>'; mysql> FLUSH PRIVILEGES; mysql> exit;
cd Autolab gem install bundler rbenv rehash bundle install
Initializing Autolab Configs
cd Autolab cp config/database.yml.template config/database.yml cp config/school.yml.template config/school.yml cp config/autogradeConfig.rb.template config/autogradeConfig.rb
Create a .env file to store Autolab configuration constants.
cp .env.template .env
If you have not installed Tango yet, you do not need to do anything else in this stage. If you have already installed Tango, you should make sure to fill in the
.envfile with values consistent with Tango's
Initialize application secrets.
(Using MySQL) Editing Database YML. Change the
and fields in config/database.yml to the username and password that has been set up for the mysql. For example if your username is
user1, and your password is
123456, then your yml would be
development: adapter: mysql2 database: autolab_development pool: 5 username: user1 password: '123456' socket: /var/run/mysqld/mysqld.sock host: localhost variables: sql_mode: NO_ENGINE_SUBSTITUTION test: adapter: mysql2 database: autolab_test pool: 5 username: user1 password: '123456' socket: /var/run/mysqld/mysqld.sock host: localhost variables: sql_mode: NO_ENGINE_SUBSTITUTION
(Using SQLite) Editing Database YML. Comment out the configurations meant for MySQL in config/database.yml, and insert the following
development: adapter: sqlite3 database: db/autolab_development pool: 5 timeout: 5000 test: adapter: sqlite3 database: db/autolab_test pool: 5 timeout: 5000
Granting permissions on the databases. Setting global sql mode is important to relax the rules of mysql when it comes to group by mode
(access mysql using your root first to grant permissions) mysql> grant all privileges on autolab_development.* to '<username>'@localhost; mysql> grant all privileges on autolab_test.* to '<username>'@localhost; mysql> SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); mysql> exit
Initializing Autolab Database
cd Autolab bundle exec rails db:create bundle exec rails db:reset bundle exec rails db:migrate
Create initial root user, pass the
-dflag for developmental deployments:
# For production: ./bin/initialize_user.sh # For development: ./bin/initialize_user.sh -d
If you are just testing Autolab, you can populate the database with sample course & students
cd Autolab bundle exec rails autolab:populate
cd Autolab bundle exec rails s -p 3000 --binding=0.0.0.0
Visit localhost:3000 on your browser to view your local deployment of Autolab, and login with either the credentials of the root user you just created, or choose
Install Tango, the backend autograding service. Information on linking Autolab to Tango can be found on this page as well.
If you would like to deploy the server, you can try out Phusion Passenger.
If you would like to configure Github integration to allow students to submit via Github, please follow the Github integration setup instructions.
