Basically, you only need the current version of the Django web framework together with its prerequisites. Typically, this will be a computer with a Linux operating system, and with Apache and PostgreSQL running on it. However, Django is flexible. Is also runs on a Windows server, and it may be combined with different webservers and database backends. See Django’s own installation guide for more information. Still, in this document, we assume the default setup, which we also strongly recommend: Linux, Apache, PostgreSQL. We deliberately avoid mentioning any particular Linux distribution because we assume that at least their server flavours are similar enough. For what it’s worth, the authors run Ubuntu Server.

JuliaBase requires Python_3.4 or higher.

Mostly, no sophisticated finetuning of the components is necessary because JuliaBase deployments will serve only a few (< 1000) people. In particular, PostgreSQL and Apache can run in default configuration by and large. On the other hand, the computer should be a high-availability system, possibly realized with virtual machines. In our own installation, we manage a three-nines system, i.e. 99.9 % availability. Additionally, regular backups are a must! To set up these things, however, is beyond the scope of this document. Your IT department may turn out to be very helpful with this.

In the following, we’ll show you how to get JuliaBase up and running quickly. While our way is already useful for a production system, you may wish or need to do it in a different way. Thus, consider the following a good starting point for your own configuration.

Linux configuration

Additionally to the software that is running on any recent and decent Linux operating system by default anyway, you must install:

  • Apache2
  • PostgreSQL (and the Python module “psycopg2” for it)
  • Redis (and the Django module for it)
  • matplotlib
  • reportlab
  • tzlocal
  • Python modules for YAML and markdown
  • Python module “deprecation”


If you have PostgreSQL and Apache on the same computer, PostgreSQL’s default configuration should work for you. The defaults are quite restrictive, so they can be considered secure. Otherwise, if you need to change something, it is probably in pg_hba.conf (where the user authentication resides) or postgresql.conf (where the general configuration resides), both of which are typically found in /etc/postgresql/version/main/.

Anyway, you create a PostgreSQL user with this:

username@server:~$ sudo -u postgres psql
psql (9.3.4)
Type "help" for help.

postgres=# CREATE USER username WITH PASSWORD 'topsecret' CREATEDB;
postgres=# \q

In this snippet, you have to replace username with your UNIX user name, and topsecret with a proper password, which shouldn’t be your UNIX login password. Finally, create the database with:

username@server:~$ createdb juliabase


A certain version of JuliaBase works only with a certain version of Django. For the JuliaBase 1.0 release, this is Django 1.7. For the current Git source code, it is Django 3.2. Install it according to Django’s own instructions. No further configuration is necessary.


Download the latest public release of JuliaBase. Moreover, JuliaBase’s source code is hosted in a public Git repository on GitHub. So if you want to use the cutting-edge JuliaBase (which probably is less reliable than the latest release), you can clone it locally with

username@server:~$ git clone

In any case, the JuliaBase source code contains three Django apps:

  1. jb_common
  2. samples
  3. institute

“jb_common” implements the basic JuliaBase functionality. On top of that, “samples” implements the actual samples database. And on top of that, “institute” implements code that is specific to the specific institution or department or work group that wants to use JuliaBase. “institute” implements a generic institute. You will replace “institute” with your own app.

While the naked Git repo is suitable to get JuliaBase up and running quickly, in the section “Organizing your source code”, we’ll explain the directory structure that you should use if you plan to actually using JuliaBase.


Add to your Apache configuration something like the following:

<VirtualHost *:80>
  WSGIScriptAlias / /home/username/myproject/mysite/
  XSendFile on
  XSendFilePath /
  Alias /static /var/www/juliabase/static
  <Directory /home/username/myproject/mysite>
      Require all granted

This snippet contains several parts that highly probably need to be adjusted by you, in particular, username, and all paths in general. But this should be obvious. The proper place for it depends on your Linux variant. It may be the (new) file /etc/apache2/httpd.conf, or a new file in /etc/apache2/conf.d, or a new file in /etc/apache2/sites-available with a symlink in /etc/apache2/sites-enabled.

Moreover, you may need to set the locale environment variables for the Apache process. On Ubuntu, all that it needed to be done is to comment out the line “. /etc/default/locale” in the file /etc/apache2/envvars. However, this sets the locale also for non-JuliaBase applications which are served by the same Apache instance. To have more fine-grained control, you can use mod_wsgi in daemon mode.
