Install and configure for openSUSE and SUSE Linux Enterprise¶

This section describes how to install and configure the neutron-interconnection service for openSUSE Leap 42.1 and SUSE Linux Enterprise Server 12 SP1.

Prerequisites¶

Before you install and configure the neutron-interconnection service, you must create a database, service credentials, and API endpoints.

To create the database, complete these steps:

Use the database access client to connect to the database server as the root user:
```
$ mysql -u root -p
```

Create the neutron_interconnection database:

CREATE DATABASE neutron_interconnection;

Grant proper access to the neutron_interconnection database:

GRANT ALL PRIVILEGES ON neutron_interconnection.* TO 'neutron_interconnection'@'localhost' \
  IDENTIFIED BY 'NEUTRON_INTERCONNECTION_DBPASS';
GRANT ALL PRIVILEGES ON neutron_interconnection.* TO 'neutron_interconnection'@'%' \
  IDENTIFIED BY 'NEUTRON_INTERCONNECTION_DBPASS';

Replace NEUTRON_INTERCONNECTION_DBPASS with a suitable password.

Exit the database access client.
```
exit;
```

Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

To create the service credentials, complete these steps:

Create the neutron_interconnection user:

$ openstack user create --domain default --password-prompt neutron_interconnection

Add the admin role to the neutron_interconnection user:

$ openstack role add --project service --user neutron_interconnection admin

Create the neutron_interconnection service entities:

$ openstack service create --name neutron_interconnection --description "neutron-interconnection" neutron-interconnection

Create the neutron-interconnection service API endpoints:

$ openstack endpoint create --region RegionOne \
  neutron-interconnection public http://controller:XXXX/vY/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
  neutron-interconnection internal http://controller:XXXX/vY/%\(tenant_id\)s
$ openstack endpoint create --region RegionOne \
  neutron-interconnection admin http://controller:XXXX/vY/%\(tenant_id\)s

Install and configure components¶

Install the packages:

# zypper --quiet --non-interactive install

Edit the /etc/neutron_interconnection/neutron_interconnection.conf file and complete the following actions:
- In the [database] section, configure database access:
```
[database]
...
connection = mysql+pymysql://neutron_interconnection:NEUTRON_INTERCONNECTION_DBPASS@controller/neutron_interconnection
```

Finalize installation¶

Start the neutron-interconnection services and configure them to start when the system boots:

# systemctl enable openstack-neutron_interconnection-api.service

# systemctl start openstack-neutron_interconnection-api.service
