=============================
Installation without DevStack
=============================
This section includes instructions for Blazar installation.
You can use the host reservation and the instance reservation once
you finish the install guide.
Download all Blazar related repos:
.. sourcecode:: console
git clone https://opendev.org/openstack/blazar
git clone https://opendev.org/openstack/blazar-nova
git clone https://opendev.org/openstack/python-blazarclient
..
Install all these projects to your working environment via:
.. sourcecode:: console
python setup.py install
..
or
.. sourcecode:: console
python setup.py develop
..
Next you need to configure Blazar and Nova. First, generate a blazar.conf sample:
.. sourcecode:: console
cd /path/to/blazar
tox -e genconfig
mv etc/blazar/blazar.conf.sample /etc/blazar/blazar.conf
..
Then edit */etc/blazar/blazar.conf* using the following example:
.. sourcecode:: console
[DEFAULT]
host=<blazar_host>
port=<blazar_port>
os_auth_host=<auth_host>
os_auth_port=<auth_port>
os_auth_protocol=<http, for example>
os_auth_version=v3
os_admin_username=<username>
os_admin_password=<password>
os_admin_project_name=<project_name>
identity_service=<identity_service_name>
os_region_name=<region_name>
[manager]
plugins=physical.host.plugin,virtual.instance.plugin
[keystone_authtoken]
auth_type=<password, for example>
project_domain_name=<project_domain_name>
project_name=<project_name>
user_domain_name=<user_domain_name>
username=<username>
password=<password>
auth_url=<identity_service_url>
..
*os_admin_** flags refer to the Blazar service user. If you do not have this
user, create it:
.. sourcecode:: console
openstack user create --password <password> --project <project_name> --email <email-address> <username>
openstack role add --project <project_name> --user <username> <admin_role>
..
Next you need to configure Nova. Please add the following lines to nova.conf file:
.. sourcecode:: console
[filter_scheduler]
available_filters = nova.scheduler.filters.all_filters
available_filters = blazarnova.scheduler.filters.blazar_filter.BlazarFilter
enabled_filters = AvailabilityZoneFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,SameHostFilter,DifferentHostFilter,BlazarFilter
..
Restart nova-scheduler to use the new configuration file.
Next you need to create a Nova aggregate to use as a free pool for host
reservation:
.. sourcecode:: console
openstack aggregate create freepool
..
And we need to create the reservation service in Keystone with its endpoints:
.. sourcecode:: console
openstack service create --name blazar --description "OpenStack Reservation Service" reservation
openstack endpoint create --region <region> blazar admin "<auth_protocol>://<blazar_host>:<blazar_port>/v1"
openstack endpoint create --region <region> blazar internal "<auth_protocol>://<blazar_host>:<blazar_port>/v1"
openstack endpoint create --region <region> blazar public "<auth_protocol>://<blazar_host>:<blazar_port>/v1"
..
And, finally, we need to create a database for Blazar:
.. sourcecode:: console
mysql -u<user> -p<password> -h<host> -e "DROP DATABASE IF EXISTS blazar;"
mysql -u<user> -p<password> -h<host> -e "CREATE DATABASE blazar CHARACTER SET utf8;"
..
Then edit the database section of */etc/blazar/blazar.conf*:
.. sourcecode:: console
[database]
connection=mysql+pymysql://<user>:<password>@<host>/blazar?charset=utf8
..
To start Blazar services use:
.. sourcecode:: console
blazar-api --config-file /etc/blazar/blazar.conf
blazar-manager --config-file /etc/blazar/blazar.conf
..
Now you can use python-blazarclient to communicate with Blazar.
