+Production Deployment
+---------------------
+
+* **Deploying Locally**
+
+ Follow these steps to deploy locally on the server.
+
+ * **Pre-Requisite**
+
+ 1. Ensure `pip <https://pip.pypa.io/en/latest/installing.html>`__ is
+ installed
+ 2. Install dependencies, Run;
+
+ ::
+
+ pip install -r requirements/requirements-py2.txt # For Python 2
+
+ pip3 install -r requirements/requirements-py3.txt # For Python 3
+
+ 3. Install MySql Server
+ 4. Install Python MySql support
+ 5. Install Apache Server for deployment
+
+ 6. Create a database named ``yaksh`` by following the steps below
+
+ ::
+
+ $> mysql -u root -p
+ $> mysql> create database yaksh
+
+ 7. Add a user named ``yaksh_user`` and give access to it on the database
+ ``yaksh`` by following the steps below
+
+ ::
+
+ mysql> grant usage on yaksh to yaksh_user@localhost identified
+ by 'mysecretpassword';
+
+ mysql> grant all privileges on yaksh to yaksh_user@localhost;
+
+ 8. Add ``DATABASE_PASSWORD = 'mysecretpassword'`` and
+ ``DATABASE_USER = 'yaksh_user'`` to online\_test/settings.py
+
+
+ * **Installation & Usage**
+
+ To install this app follow the steps below:
+
+ 1. Clone this repository and cd to the cloned repo.
+
+ ::
+
+ $ git clone https://github.com/FOSSEE/online_test.git
+
+ 2. Rename the ``.sampleenv`` to ``.env``
+
+ 3. In the ``.env`` file, uncomment the following and replace the values (please keep the remaining settings as is);
+
+ ::
+
+ DB_ENGINE=mysql # Or psycopg (postgresql), sqlite3 (SQLite)
+ DB_NAME=yaksh
+ DB_USER=root
+ DB_PASSWORD=mypassword # Or the password used while creating a Database
+ DB_PORT=3306
+
+ 4. Run:
+
+ ::
+
+ $ python manage.py makemigrations yaksh
+
+ $ python manage.py migrate yaksh
+
+ 5. Run the python server provided. This ensures that the code is
+ executed in a safe environment. Do this like so:
+
+ ::
+
+ $ sudo python -m yaksh.code_server # For Python 2.x
+
+
+ $ sudo python3 -m yaksh.code_server # For Python 3.x
+
+ Put this in the background once it has started since this will not
+ return back the prompt. It is important that the server be running
+ *before* students start attempting the exam. Using sudo is necessary
+ since the server is run as the user "nobody". This runs the number
+ ports configured in the settings.py file in the variable
+ "N\_CODE\_SERVERS". The "SERVER\_TIMEOUT" also can be changed there.
+ This is the maximum time allowed to execute the submitted code. Note
+ that this will likely spawn multiple processes as "nobody" depending
+ on the number of server ports specified.
+
+ You can also use a Dockerized code server, see `Dockerized Code Server`
+
+
+ 6. The ``wsgi.py`` script should make it easy to deploy this using
+ mod\_wsgi. You will need to add a line of the form:
+
+ ::
+
+ WSGIScriptAlias / "/online_test/wsgi.py"
+
+ to your apache.conf. For more details see the Django docs here:
+
+ https://docs.djangoproject.com/en/2.0/howto/deployment/wsgi/
+
+ 7. Create a Superuser/Administrator:
+
+ ::
+
+ python manage.py createsuperuser
+
+ 8. Go to http://desired\_host\_or\_ip:desired\_port/exam
+
+ And you should be all set.
+
+ 9. Note that the directory "output" will contain directories, one for
+ each user. Users can potentially write output into these that can be
+ used for checking later.
+
+ 10. As a moderator you can visit http://desired\_host\_or\_ip/exam/monitor to view results and user data interactively. You could also "grade" the papers manually if needed.
+
+.. _dockerized-code-server:
+
+* **Using Dockerized Code Server**
+
+ 1. Install
+ `Docker <https://docs.docker.com/engine/installation/>`__
+
+ 2. Go to the directory where the project is located
+
+ ::
+
+ cd /path/to/online_test
+
+ 3. Create a docker image. This may take a few minutes,
+
+ ::
+
+ docker build -t yaksh_code_server -f ./docker/Dockerfile_codeserver
+
+ 4. Check if the image has been created using the output of ``docker
+ images``
+
+ 5. Run the invoke script using the command ``invoke start`` The command
+ will create and run a new docker container (that is running the
+ code\_server.py within it), it will also bind the ports of the host
+ with those of the container
+
+ 6. You can use ``invoke --list`` to get a list of all the available commands
+
+
+ .. _deploying-multiple-dockers:
+
+
+* **Deploying Multiple Dockers**
+
+ Follow these steps to deploy and run the Django Server, MySQL instance and Code Server in seperate Docker instances.
+
+ 1. Install `Docker <https://docs.docker.com/engine/installation/>`__
+
+ 2. Install `Docker Compose <https://docs.docker.com/compose/install/>`__
+
+ 3. Rename the ``.sampleenv`` to ``.env``
+
+ 4. In the ``.env`` file, uncomment all the values and keep the default values as is.
+
+ 5. Go to the ``docker`` directory where the project is located:
+
+ ::
+
+ cd /path/to/online_test/docker
+
+ 6. Build the docker images
+
+ ::
+
+ invoke build
+
+ 7. Run the containers and scripts necessary to deploy the web
+ application
+
+ ::
+
+ invoke begin
+
+ 8. Make sure that all the containers are ``Up`` and stable
+
+ ::
+
+ invoke status
+
+ 8. Run the containers and scripts necessary to deploy the web
+ application, ``--fixtures`` allows you to load fixtures.
+
+ ::
+
+ invoke deploy --fixtures
+
+ 10. Stop the containers, you can use ``invoke restart`` to restart the containers without removing them
+
+ ::
+
+ invoke halt
+
+ 11. Remove the containers
+
+ ::
+
+ invoke remove
+
+ 12. You can use ``invoke --list`` to get a list of all the available commands
+
+
+ .. _add-commands:
+
+* **Additional commands available**
+
+ We provide several convenient commands for you to use:
+
+ - load\_exam : load questions and a quiz from a python file. See
+ docs/sample\_questions.py
+
+ - load\_questions\_xml : load questions from XML file, see
+ docs/sample\_questions.xml use of this is deprecated in favor of
+ load\_exam.
+
+ - results2csv : Dump the quiz results into a CSV file for further
+ processing.
+
+ - dump\_user\_data : Dump out relevalt user data for either all users
+ or specified users.
+
+ For more information on these do this:
+
+ ::
+
+ $ python manage.py help [command]
+
+ where [command] is one of the above.
