Installation dependencies (CentOS 7.x)

box# easy_install pip
box# yum install -y gcc python-devel openldap-devel memcached httpd mod_wsgi mod_ssl git
box# systemctl enable memcached httpd
box# systemctl start memcached httpd

box# cd /opt
box# git clone https://github.com/LAL/openstack-lease-it.git
box# cd openstack-lease-it
box# pip install -r requirements.txt

Configuration file and test

box# mkdir -p /etc/openstack-lease-it
box# cp openstack_lease_it/config/* /etc/openstack-lease-it

Modify /etc/openstack-lease-it/config.ini to match your configuration. You must also need to disabled selinux to allow apache to read /etc/openstack-lease-it/config.ini or configure it to allow that.

You must modify /opt/openstack-lease-it/openstack_lease_it/openstack_lease_it/settings.py to change

ALLOWED_HOSTS = [ '*' ]

Configure database

By default, we use sqlite3 database. to populate it

box# cd /opt/openstack-lease-it/openstack_lease_it
box# python manage.py makemigrations
box# python manage.py migrate
box# chown -R apache:apache .

Configure Apache

We copy apache config to /etc/httpd/conf.d/lease-it.conf

box# cp openstack_lease_it/config/http-lease-it.conf /etc/httpd/conf.d/lease-it.conf

You should modify it to match your configuration but if you follow the current guide, there are no modification to do.

After apache configuration you must restart httpd service with the following command

box# systemctl restart httpd

Configure log directory

box# mkdir -p /var/log/openstack-lease-it
box# chown -R apache:apache /var/log/openstack-lease-it

Instance-spy crontab

To monitor instances and notify user when a instance is close to expire, we use a crontab. To do so, put the cron script to cron directory

box# cp openstack_lease_it/config/instance-spy.cron /etc/cron.daily/
box# chmod +x /etc/cron.daily/instance-spy.cron

Make sure that the PYTHONPATH on script is in the right place. This script should also be modified if you use virtualenv
