Blazar Installation Guide <\/b><\/h2>\n

1.1.1 Installation using DevStack <\/b><\/p>\n

This section includes instructions for Blazar installation using DevStack<\/a>. DevStack configures both the host<\/a> reservation and the instance reservation.<\/p>\n

1. Download DevStack:
\ngit clone https:\/\/opendev.org\/openstack\/devstack.git<\/p>\n

2. Create a local.conf file in the devstack directory. You can use the following sample local.conf:
\n[[local|localrc]]
\nADMIN_PASSWORD=password
\nDATABASE_PASSWORD=$ADMIN_PASSWORD
\nRABBIT_PASSWORD=$ADMIN_PASSWORD
\nSERVICE_PASSWORD=$ADMIN_PASSWORD
\nDEST=\/opt\/stack\/
\nLOGFILE=$DEST\/logs\/stack.sh.log
\nHOST_IP=127.0.0.1
\nGIT_BASE=https:\/\/opendev.org\/
\nRECLONE=yes
\nenable_plugin blazar https:\/\/opendev.org\/openstack\/blazar<\/p>\n

3. Run DevStack as the stack user<\/a>:
\n.\/stack.sh<\/p>\n

4. Source the admin credentials:
\n. openrc admin admin<\/p>\n

5. Now you can add hosts to Blazar:
\nblazar host-create hostname<\/p>\n

1.1.2 Installation without DevStack\u00a0<\/b><\/p>\n

This section includes instructions for Blazar installation. You can use the host reservation and the instance reservation once you finish the install guide.<\/p>\n

Download all Blazar related repos:
\ngit clone https:\/\/opendev.org\/openstack\/blazar
\ngit clone https:\/\/opendev.org\/openstack\/blazar-nova
\ngit clone https:\/\/opendev.org\/openstack\/python-blazarclient<\/p>\n

Install all these projects to your working environment via:
\npython setup.py install
\nor
\npython setup.py develop<\/p>\n

Next you need to configure Blazar and Nova. First, generate a blazar.conf sample:
\ncd \/path\/to\/blazar
\ntox -e genconfig
\nmv etc\/blazar\/blazar.conf.sample \/etc\/blazar\/blazar.conf<\/p>\n

Then edit\u00a0\/etc\/blazar\/blazar.conf\u00a0<\/i>using the following example:<\/p>\n

[DEFAULT]
\nhost=<blazar_host>
\nport=<blazar_port>
\nos_auth_host=<auth_host>
\nos_auth_port=<auth_port>
\nos_auth_protocol=<http, for example>
\nos_auth_version=v3
\nos_admin_username=<username>
\nos_admin_password=<password>
\nos_admin_project_name=<project_name>
\nidentity_service=<identity_service_name>
\nos_region_name=<region_name>
\n[manager]
\nplugins=physical.host.plugin,virtual.instance.plugin
\n[keystone_authtoken]
\nauth_type=<password, for example>
\nproject_domain_name=<project_domain_name>
\nproject_name=<project_name>
\nuser_domain_name=<user_domain_name>
\nusername=<username>
\npassword=<password>
\nauth_url=<identity_service_url><\/p>\n

os_admin_*\u00a0<\/i>flags refer to the Blazar service user. If you do not have this user, create it:<\/p>\n

openstack user create –password <password> –project <project_name> –email<\/span>
\u21aa<\/span>\u2192<\/span><email-address> <username><\/span>
openstack role add –project <project_name> –user <username> <admin_role><\/span><\/p>\n

Next you need to configure Nova. Please add the following lines to nova.conf file:<\/span>
[filter_scheduler]<\/span>
available_filters = nova.scheduler.filters.all_filters<\/span>
available_filters = blazarnova.scheduler.filters.blazar_filter.BlazarFilter<\/span>
enabled_filters = AvailabilityZoneFilter,ComputeFilter,<\/span>
\u21aa<\/span>\u2192<\/span>ComputeCapabilitiesFilter,ImagePropertiesFilter,<\/span>
\u21aa<\/span>\u2192<\/span>ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,SameHostFilter,<\/span>
\u21aa<\/span>\u2192<\/span>DifferentHostFilter,BlazarFilter<\/span><\/p>\n

Restart nova-scheduler to use the new configuration file.<\/span><\/p>\n

Next you need to create a Nova aggregate to use as a free pool for host reservation:
\n<\/span>openstack aggregate create freepool<\/span><\/p>\n


And we need to create the reservation service in Keystone with its endpoints:<\/span><\/p>\n

openstack service create –name blazar –description “OpenStack Reservation<\/span>\u2423<\/span>
\u21aa<\/span>\u2192<\/span>Service” reservation<\/span>
openstack endpoint create –region <region> blazar admin “<auth_protocol>:\/\/<\/span>
\u21aa<\/span>\u2192<\/span><blazar_host>:<blazar_port>\/v1″<\/span>
openstack endpoint create –region <region> blazar internal “<auth_protocol>:\/<\/span>
\u21aa<\/span>\u2192<\/span>\/<blazar_host>:<blazar_port>\/v1″<\/span>
openstack endpoint create –region <region> blazar public “<auth_protocol>:\/\/<\/span>
\u21aa<\/span>\u2192<\/span><blazar_host>:<blazar_port>\/v1″<\/span><\/p>\n

And, finally, we need to create a database for Blazar:<\/span>
mysql -u<user> -p<password> -h<host> -e “DROP DATABASE IF EXISTS blazar;”<\/span>
mysql -u<user> -p<password> -h<host> -e “CREATE DATABASE blazar CHARACTER SET<\/span>\u2423<\/span>
\u21aa<\/span>\u2192<\/span>utf8;”<\/span><\/p>\n

Then edit the database section of<\/span> \/etc\/blazar\/blazar.conf<\/span> :<\/span>
[database]<\/span>
connection=mysql+pymysql:\/\/<user>:<password>@<host>\/blazar?charset=utf8<\/span><\/p>\n

To start Blazar services use:<\/span>
blazar-api –config-file \/etc\/blazar\/blazar.conf<\/span>
blazar-manager –config-file \/etc\/blazar\/blazar.conf<\/span><\/p>\n

Now you can use python-blazarclient to communicate with Blazar.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
