A CentOS 7.6 Vagrant Box with Python 3.6 via Ansible
- Apache 2.4, with mod_wsgi for running Django
- Microsoft ODBC & FreeTDS drivers for MS SQL Server
- PostgreSQL Drivers & Server
This repository contains a CentOS 7.6 box for Vagrant. Python 3.6 is installed alongside the system Python (2.7.5). The Vagrant config uses Ansible roles to configure the box for the development environment, that should also be (mostly) suitable for setting up a production server.
Pygments are installed with the system Python, and bash aliases exist to
cdsitepackages (for those used to
PostgreSQL 10 server is installed locally for full-stack local development. MS SQL is also supported as a Django database backend with either the Microsoft provided ODBC driver or the FreeTDS ODBC Driver to an external SQL Server.
wkhtmltopdf is installed for compatibility with Python's PDF kit.
Django 1.11 or greater is recommended at the time of this writing for new projects. Django 1.11 is an LTS (Long Term Support) release, meaning it will be actively supported with bug fixes and security patches until at least April, 2020 (and probably longer): https://www.djangoproject.com/download/#supported-versions

- Vagrant 2.2.5 can be downloaded here: https://www.vagrantup.com/downloads.html
- Builds are provided for Debian/Ubuntu, CentOS/RHEL, Arch, and vanilla Linux.
- On newer machines, ensure that you have virtualization enabled in BIOS (duckduckgo it for your machine's model).
Fedora 25, CentOS 7
These are available via the package manager.
$ sudo dnf install vagrant $ sudo dnf install VirtualBox
Additional Roles Not Installed by Default
The Ansible playbook for the installation is located at
provisioning/vagrant_playbook.yml. Several additional roles are commented out that can be added, including
nodejs, and a
yum_update role. These are not included by default, but can be uncommented if you wish you use them.
- Create and add a public SSH key to your git server (GitHub, GitLab, etc).
- Clone the repository and bring up the virtual development environment. The first time you install the box, "vagrant up" will take a little while. Grab a cup of coffee or something!
- You may want to use a host name for your domain; for example, if you're a member of The Wharton School, you may want to use the command
VAGRANT_HOSTNAME="vagrant.wharton.upenn.edu" vagrant upbelow instead of
vagrant up. If you don't provide a hostname, you will be prompted for one. If you don't have one, feel free to use
- The Vagrant plugin
vagrant-vbguestwill cause problems with the shared folder in most cases. Please uninstall the plugin first if you have it installed with
vagrant plugin uninstall vagrant-vbguest.
git clone https://github.com/wharton/python-vagrant-centos7.git cd python-vagrant-centos7 vagrant up vagrant ssh
Fedora 25, CentOS 7
Check Vagrantfile and make sure the port forwarding settings will work for your use case. You may wish to forward the guest VM port 80 to something other than port 80 on the host, e.g. 8888.
config.vm.network "forwarded_port", guest: 80, host: 8888, auto_correct: false
Replace the the
vagrant up line from above with the following.
$ vagrant up --provider=virtualbox
Sit back, and let the installation complete.
You can also add the host name to your computer's
hostsfile should be located at:
- Mac / Linux: /etc/hosts
- Windows: %SystemRoot%\system32\drivers\etc\hosts
Add this line (with the appropriate host name, if you changed it):
Default installation creates
default: SSH address: 127.0.0.1:2222 default: SSH username: vagrant default: SSH auth method: private key
$ vagrant ssh
Another, less desirable, option for SSH'ing into the vagrant box.. (this requires the use of the default password, vagrant)
$ ssh firstname.lastname@example.org -p 2222
At this point, you should change the default password for the vagrant user. You may also want to add/remove users soon.
Using PostgreSQL & Creating a New Database for a Django Project
The Vagrant box comes with PostgreSQL 9.6. The
vagrant user is set up as a PostgreSQL superuser (in addition to the
$ psql psql (10.7) Type "help" for help. vagrant=# \? ... vagrant=# CREATE USER my_django_user WITH PASSWORD 'my_django_password'; CREATE ROLE vagrant=# CREATE DATABASE my_django_db WITH OWNER my_django_user; CREATE DATABASE vagrant=# \q
Setting Up Django & virtualenv
First, change to the directory set aside to hold user projects.
$ cd projects
Next, create a new virtual environment for your Django project:
$ mkvirtualenv django-project
Next, within this virtualenv, install
(django-project) [vagrant@vagrant django-project]$ pip install django django-extensions pygraphviz
Now, create a new Django project and enter its directory:
(django-project) [vagrant@vagrant django-project]$ django-admin startproject myproject (django-project) [vagrant@vagrant django-project]$ cd myproject
Creating ERDs of Django Models
django-extensions app can build handy Entity Relationship Diagrams for Django apps, even your entire project. The pre-requisites for the Python packages are included with this Vagrant box.
First, within your Django project's virtualenv, install
(django-project) [vagrant@vagrant django-project]$ pip install django-extensions pygraphviz
django_extensions to your
INSTALLED_APPS. Then you can create the diagrams; to create a PNG of all models in your Django project.
$ ./manage.py graph_models -a -g -o project-erd.png
Or, to just do a few Django apps:
$ ./manage.py graph_models users faculty courses -g -o users-faculty-courses.png
Windows 10: Forwarding Port 80 for Testing Apache
In Windows 10, the "World Wide Web Publishing Service" automatically starts on port 80. You can disable it so Vagrant can forward port 80.
- Click Start, type "Services" and open Services.
- Scroll down to World Wide Web Publishing Service. Right click and go into Properties.
- Change "Startup type" to be Manual.
- Click the "Stop" button.
- Click "OK".
