two。 Create neutron users and projects
[root@localhost ~] # source / root/admin-openrc
[root@localhost] # openstack user create-- domain default neutron-- password devops

3. Install neuton services and modify configuration files
[root@localhost ~] # yum-y install openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables
[root@controller ~] # cp / etc/neutron/neutron.conf / etc/neutron/neutron.conf.bak
[root@controller ~] # > / etc/neutron/neutron.conf

4. Create a connection and create a keystone user
[root@localhost] # ln-s / etc/neutron/plugins/ml2/ml2_conf.ini / etc/neutron/plugin.ini
5. Update the database
[root@localhost] # su-s / bin/sh-c "neutron-db-manage-- config-file / etc/neutron/neutron.conf-- config-file / etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
[root@localhost ~] # systemctl restart openstack-nova-api.service
[root@controller ~] # systemctl status openstack-nova-api.service
6. Start the service
[root@localhost ~] # systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
[root@localhost ~] # systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service
Start neutron-l3-agent.service and set boot up
# systemctl enable neutron-l3-agent.service
* * # systemctl restart neutron-l3-agent.service
# systemctl status neutron-l3-agent.service
[root@controller ~] # neutron ext-list
[root@localhost ~] # neutron agent-list
7. View registration information
[root@localhost ~] # openstack endpoint list
