| [1] |
Install KVM HyperVisor on Compute Node Host, refer to here.
It's unnecessarry to set Bridge networking on the section [2] of the link. |
| [2] | Install Nova Compute. |
|
[root@dlp ~(keystone)]# dnf --enablerepo=centos-openstack-xena,epel,powertools -y install openstack-nova-compute
|
| [3] | In addition to basic settings of Nova, add following settings. |
|
[root@dlp ~(keystone)]#
vi /etc/nova/nova.conf # add into the [DEFAULT] section compute_driver = libvirt.LibvirtDriver # add follows (enable VNC) [vnc] enabled = True server_listen = 0.0.0.0 server_proxyclient_address = 10.0.0.30 novncproxy_base_url = http://10.0.0.30:6080/vnc_auto.html |
| [4] | If SELinux is enabled, change policy. |
|
[root@dlp ~(keystone)]# dnf --enablerepo=centos-openstack-xena -y install openstack-selinux |
| [5] | If Firewalld is running, allow ports for services. |
|
[root@dlp ~(keystone)]# firewall-cmd --add-port=5900-5999/tcp success [root@dlp ~(keystone)]# firewall-cmd --runtime-to-permanent success |
| [6] | Start Nova Compute. |
|
[root@dlp ~(keystone)]#
systemctl enable --now openstack-nova-compute openstack-nova-novncproxy
# discover Compute Node [root@dlp ~(keystone)]# su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"
# show status [root@dlp ~(keystone)]# openstack compute service list +----+----------------+---------------+----------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+----------------+---------------+----------+---------+-------+----------------------------+ | 6 | nova-conductor | dlp.srv.world | internal | enabled | up | 2021-11-22T03:32:30.000000 | | 10 | nova-scheduler | dlp.srv.world | internal | enabled | up | 2021-11-22T03:32:30.000000 | | 14 | nova-compute | dlp.srv.world | nova | enabled | up | 2021-11-22T03:32:28.000000 | +----+----------------+---------------+----------+---------+-------+----------------------------+ |
