|
| [1] | Install Magnum services on Network Node. |
|
[root@network ~]# dnf --enablerepo=centos-openstack-victoria,powertools,epel -y install openstack-magnum-api openstack-magnum-conductor python3-magnumclient
|
| [2] | Configure Magnum. |
|
[root@network ~]# mv /etc/magnum/magnum.conf /etc/magnum/magnum.conf.org
[root@network ~]#
vi /etc/magnum/magnum.conf # create new [DEFAULT] state_path = /var/lib/magnum rootwrap_config = /etc/magnum/rootwrap.conf log_dir = /var/log/magnum # RabbitMQ connection info transport_url = rabbit://openstack:password@10.0.0.30 [api] host = 10.0.0.50 port = 9511 enabled_ssl = False [database] # MariaDB connection info connection = mysql+pymysql://magnum:password@10.0.0.30/magnum [barbican_client] region_name = RegionOne [certificates] cert_manager_type = barbican [cinder] default_docker_volume_type = lvm-magnum [cinder_client] region_name = RegionOne [magnum_client] region_name = RegionOne [glance_client] region_name = RegionOne [nova_client] region_name = RegionOne [neutron_client] region_name = RegionOne [heat_client] region_name = RegionOne # Keystone auth info [keystone_authtoken] www_authenticate_uri = http://10.0.0.30:5000/v3 auth_url = http://10.0.0.30:5000 memcached_servers = 10.0.0.30:11211 auth_type = password auth_version = v3 project_domain_name = default user_domain_name = default project_name = service username = magnum password = servicepassword admin_user = magnum admin_password = servicepassword admin_tenant_name = service [oslo_messaging_notifications] driver = messagingv2 [trust] trustee_domain_name = magnum trustee_domain_admin_name = magnum_domain_admin trustee_domain_admin_password = servicepassword trustee_keystone_interface = public chmod 640 /etc/magnum/magnum.conf [root@network ~]# chgrp magnum /etc/magnum/magnum.conf [root@network ~]# mkdir /var/lib/magnum/tmp [root@network ~]# chown magnum /var/lib/magnum/tmp [root@network ~]# su -s /bin/bash magnum -c "magnum-db-manage upgrade" [root@network ~]# systemctl enable --now openstack-magnum-api openstack-magnum-conductor |
| [3] | If Firewalld is running, allow service port. |
|
[root@network ~]# firewall-cmd --add-port=9511/tcp --permanent success [root@network ~]# firewall-cmd --reload success |
| [4] | Verify Magnum service status on Control Node. That's OK if state is [up]. Also Create a Cinder volume type configured in [magnum.conf]. |
