# Install from Git Source Code

## Install Senlin Server

1. Get Senlin source code from OpenStack git repository.

    $ cd /opt/stack
    $ git clone https://git.openstack.org/openstack/senlin.git

2. Install Senlin with required packages.

    $ cd /opt/stack/senlin
    $ sudo pip install -e .

3. Register Senlin clustering service with keystone.

   This can be done using the setup-service script under the `tools` folder.

   NOTE: Suppose you have devstack installed under the `/opt/devstack` folder

    $ . /opt/devstack/openrc admin admin
    $ cd /opt/stack/senlin/tools
    $ ./setup-service <HOST IP> <SERVICE_PASSWORD>

4. Generate configuration file for the Senlin service.

    $ cd /opt/stack/senlin
    $ 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:

    [database]
    connection = mysql+pymysql://senlin:<MYSQL_SENLIN_PW>@127.0.0.1/senlin?charset=utf8

    [keystone_authtoken]
    service_token_roles_required = True
    auth_type = password
    user_domain_name = Default
    project_domain_name = Default
    project_name = service
    username = senlin
    password = <SENLIN_PASSWORD>
    www_authenticate_uri = http://<HOST>/identity/v3
    auth_url = http://<HOST>/identity

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

    [oslo_messaging_rabbit]
    rabbit_userid = <RABBIT USER ID>
    rabbit_hosts = <HOST>
    rabbit_password = <RABBIT PASSWORD>

    [oslo_messaging_notifications]
    driver = messaging

For more comprehensive helps on configuration options, please refer to Configuration Options documentation.

In case you want to modify access policies of Senlin, please generate sample policy file, copy it to /etc/senlin/policy.yaml and then update it.

    $ cd /opt/stack/senlin
    $ tools/gen-policy
    $ sudo cp etc/senlin/policy.yaml.sample /etc/senlin/policy.yaml

5. Create Senlin Database.

Create Senlin database using the senlin-db-recreate script under the `tools` subdirectory. Before calling the script, you need edit it to customize the password you will use for the `senlin` user. You need to update this script with the <DB PASSWORD> entered in step4.

    $ cd /opt/stack/senlin/tools
    $ ./senlin-db-recreate

6. Start the senlin api, conductor, engine and health-manager services.

You may need multiple consoles for the services i.e., one for each service.

    $ senlin-conductor --config-file /etc/senlin/senlin.conf
    $ senlin-engine --config-file /etc/senlin/senlin.conf
    $ senlin-health-manager --config-file /etc/senlin/senlin.conf
    $ senlin-api --config-file /etc/senlin/senlin.conf

## Install Senlin Client

1. Get Senlin client code from OpenStack git repository.

    $ cd /opt/stack
    $ git clone https://git.openstack.org/openstack/python-senlinclient.git

2. Install senlin client.

    $ cd python-senlinclient
    $ sudo python setup.py install
