$ tools/gen-config
$ sudo mkdir /etc/senlin
$ sudo cp etc/senlin/api-paste.ini /etc/senlin
$ sudo cp etc/senlin/senlin.conf.sample /etc/senlin/senlin.conf

Edit file /etc/senlin/senlin.conf according to your system settings. The most common options to be customized include:

connection = mysql+pymysql://senlin:<MYSQL_SENLIN_PW>@

www_authenticate_uri = http://<HOST>:5000/v3
auth_version = 3
identity_uri = http://<HOST>:5000
admin_user = senlin
admin_password = <SENLIN PASSWORD>
admin_tenant_name = service

auth_url = http://<HOST>:5000/v3
service_username = senlin
service_password = <SENLIN PASSWORD>
service_project_name = service

rabbit_userid = <RABBIT USER ID>
