Download and Installation

The following steps capture how to install valence. All installation steps require super user permissions.

Valence installation

1. Install software dependencies

   $ sudo apt-get install git python-pip rabbitmq-server libyaml-0-2 python-dev

2. Configure RabbitMq Server

   $ sudo rabbitmqctl add_user rsd rsd #user this username/pwd in valence.conf

   $ sudo rabbitmqctl set_user_tags rsd administrator

   $ sudo rabbitmqctl set_permissions rsd ".*" ".*" ".*"

3. Clone the Valence code from git repo and change the directory to root Valence folder.

4. Install all necessary software pre-requisites using the pip requirements file.

   $ sudo -E pip install -r requirements.txt

5. Execute the 'install_valence.sh' file the Valence root directory.

   $ ./install_valence.sh

6. Check the values in valence.conf located at /etc/valence/valence.conf

   set the ip/credentials of podm for which this Valence will interact

   set the rabbitmq user/password to the one given above(Step 2)

7. Check the values in /etc/init/valence-api.conf, /etc/init/valence-controller.conf

8. Start api and controller services

   $ service valence-api start

   $ service valence-controller start

9. Logs are located at /var/logs/valence/

GUI installation

Please refer to the installation steps in the ui/README file.

Components

Valence follows the typical OpenStack project setup. The components are listed below:

valence-api

A pecan based daemon to expose Valence REST APIs. The api service communicates to the controller through AMQP.

valence-controller

The controller implements all the handlers for Plasma-api. It reads requests from the AMQP queue, process it and send the reponse back to the caller.

valence-ui

valence-ui provides a GUI interface to invoke Valence APIs.
