Django environment setup

Introduction

Django is used for handling database communication and displaying WebUI.

Basic installation

These instructions are made for Ubuntu, but should work in the same principals with other distributions.
Installation is made to OTS server.

1. Install django 

sudo apt-get install python-django

In Fedora: 

sudo yum install Django

2. Download the latest django xml-rpc plugin 

https://launchpad.net/django-xmlrpc

3. Install django plug-in 

tar xzf django_xmlrpc-0.1.tar.gz
sudo mv django_xmlrpc /usr/local/lib/python2.6/dist-packages/

In Fedora (as root): 

mv django_xmlrpc /usr/lib/python2.6/site-packages/
chcon -R -t httpd_user_content_t /usr/lib/python2.6/site-packages/django_xmlrpc
chcon -R -t httpd_user_content_t /opt/ots
setsebool -P httpd_unified 1
setsebool -P httpd_tmp_exec 1

Enable/disable Django applications

From 0.8.3 release, this is not necessary anymore. Plug-ins are loaded automatically.

1. Edit Django settings 

sudo nano /usr/local/lib/python2.6/dist-packages/ots/django/settings.py

In Fedora: 

sudo nano /usr/lib/python2.6/site-packages/ots/django/settings.py

2. Comment/uncomment OTS components in 'INSTALLED_APPS' section 

# OTS components:
'ots.plugin.logger',
'ots.plugin.monitor',
'ots.plugin.history'

Create/update databases

1. Create database 

sudo python /usr/local/lib/python2.6/dist-packages/ots/django/manage.py syncdb --settings=settings

In Fedora: 

 sudo python /usr/lib/python2.6/site-packages/ots/django/manage.py syncdb --settings=settings

2. Set permissions to database file 

sudo chown www-data:www-data /opt/ots
sudo chown www-data:www-data /opt/ots/ots.sqlite

In Fedora: 

sudo chown apache:apache /opt/ots
sudo chown apache:apache /opt/ots/ots.sqlite

Apache configuration

1. Install Apache2 and Apache2 modules 

sudo apt-get install libapache2-mod-wsgi apache2-mpm-prefork libapache2-mod-python
