OpenStack-neutron component deployment

One, ct node deployment

1. Create a neutron database and authorize

MariaDB [nova]> CREATE DATABASE neutron;

MariaDB [nova]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@‘localhost’ IDENTIFIED BY ‘NEUTRON_DBPASS’;

MariaDB [nova]> GRANT ALL PRIVILEGES ON neutron.* TO ‘neutron’@’%’ IDENTIFIED BY ‘NEUTRON_DBPASS’;

MariaDB [nova]> FLUSH PRIVILEGES;

2. Create a neutron user for authentication in keystone

[root@ct ~]# openstack user create --domain default --password NEUTRON_PASS neutron

Insert picture description here

3. Add the neutron user to the service project

#Make it have admin rights

[root@ct ~]# openstack role add --project service --user neutron admin

4. Create a network service, the service type is network

[root@ct ~]# openstack service create --name neutron --description “OpenStack Networking” network

5. Register API to neutron service

#Associate the port to the neutron service, that is, add an endpoint

[root@ct ~]# openstack endpoint create --region RegionOne network public http://ct:9696

[root@ct ~]# openstack endpoint create --region RegionOne network internal http://ct:9696

[root@ct ~]# openstack endpoint create --region RegionOne network admin http://ct:9696
