Add manual installation guide
1. What is the problem? We already have guides for users to install the Tricircle with DevStack. But a guide discussing how to install the Tricircle step by step without DevStack is also needed for users who install OpenStack manually. 2. What is the solution to the problem? Add manual installation guide, and link it to the Tricircle docs page. 3. What the features need to be implemented to the Tricircle to realize the solution? No new features Change-Id: I45344df2ccb27c5096d66f00e4e76efa07d66012

===================

Manual Installation
|
||||
===================
|
||||
|
||||
The Tricircle works with Neutron to provide networking automation functionality
|
||||
across Neutron in multi-region OpenStack deployment. In this guide we discuss
|
||||
how to manually install the Tricircle with local and central Neutron server.
|
||||
|
||||
Local Neutron server, running with the Tricircle local plugin, is responsible
|
||||
for triggering cross-Neutron networking automation. Every OpenStack instance
|
||||
has one local Neutron service, registered in the same region with other core
|
||||
services like Nova, Cinder, Glance, etc. Central Neutron server, running with
|
||||
the Tricircle central plugin, is responsible for unified resource allocation
|
||||
and cross-Neutron networking building. Besides regions for each OpenStack
|
||||
instance, we also need one specific region for central Neutron service. Only
|
||||
the Tricircle administrator service needs to be registered in this region along
|
||||
with central Neutron service while other core services are not mandatory.
|
||||
|
||||
Installation with Central Neutron Server
|
||||
========================================
|
||||
|
||||
- 1 Install the Tricircle package::
|
||||
|
||||
git clone https://github.com/openstack/tricircle.git
|
||||
cd tricircle
|
||||
pip install -e .
|
||||
|
||||
- 2 Register the Tricircle administrator API to Keystone::
|
||||
|
||||
openstack user create tricircle --password password
|
||||
openstack role add --project service --user tricircle service
|
||||
openstack service create tricircle --name tricircle --description "Cross Neutron Networking Automation Service"
|
||||
service_id=$(openstack service show tricircle -f value -c id)
|
||||
service_host=162.3.124.201
|
||||
service_port=19999
|
||||
service_region=CentralRegion
|
||||
service_url=http://$service_host:$service_port/v1.0
|
||||
openstack endpoint create $service_id --publicurl $service_url --adminurl $service_url --internalurl $service_url --region $service_region
|
||||
|
||||
change password, service_host, service_port and service_region in the above
|
||||
commands to adapt your deployment. OpenStack CLI tool will automatically find
|
||||
the endpoints to send to registration requests. If you would like to specify
|
||||
the region for endpoints, use::
|
||||
|
||||
openstack --os-region-name <region_name> <command>
|
||||
|
||||
- 3 Generate the Tricircle configuration sample::
|
||||
|
||||
cd tricircle
|
||||
oslo-config-generator --config-file=etc/api-cfg-gen.conf
|
||||
oslo-config-generator --config-file=etc/xjob-cfg-gen.conf
|
||||
|
||||
The generated sample files are located in tricircle/etc
|
||||
|
||||
- 4 Configure the Tricircle administrator API::
|
||||
|
||||
cd tricircle/etc
|
||||
cp api.conf.sample api.conf
|
||||
|
||||
Edit etc/api.conf, for detail configuration information, please refer to the
|
||||
configuration guide. Below only options necessary to be changed are listed.
|
||||
|
||||

.. note:: The Tricircle utilizes the Oslo library to setup service, database,
|
||||
log and RPC, please refer to the configuration guide of the corresponding
|
||||
Oslo library if you need further configuration of these modules. Change
|
||||
keystone_service_host to the address of Keystone service.
|
||||
|
||||
- 5 Create the Tricircle database(take mysql as an example)::
|
||||
|
||||
mysql -uroot -p -e "create database tricircle character set utf8;"
|
||||
cd tricircle
|
||||
python cmd/manage.py etc/api.conf
|
||||
|
||||
- 6 Start the Tricircle administrator API::

- 9 Setup central Neutron server
|
||||
|
||||
In this guide we assume readers are familiar with how to install Neutron
|
||||
server, so we just briefly discuss the steps and extra configuration needed
|
||||
by central Neutron server. For detail information about the configuration
|
||||
options in "client" and "tricircle" groups, please refer to the configuration
|
||||
guide. Neutron server can be installed alone, or you can install a full
|
||||
OpenStack instance then remove or stop other services.
|
||||
|
||||
- install Neutron package
|
||||
|
||||
- configure central Neutron server

|
||||
|
||||
- create database for central Neutron server
|
||||
|
||||
- register central Neutron server endpoint in Keystone, central Neutron
|
||||
should be registered in the same region with the Tricircle
|
||||
|
||||
- start central Neutron server
