| [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-yoga,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 into the [vnc] section # IP address compute instances listen [vnc] enabled = True server_listen = 10.0.0.30 server_proxyclient_address = 10.0.0.30 novncproxy_host = 127.0.0.1 novncproxy_port = 6080 novncproxy_base_url = https://dlp.srv.world:6080/vnc_auto.html |
| [4] | If SELinux is enabled, change policy. |
|
[root@dlp ~(keystone)]# dnf --enablerepo=centos-openstack-yoga -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
# 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 | +--------------------------------------+----------------+---------------+----------+---------+-------+----------------------------+ | b7e0deee-86ea-4d5a-ab20-0ec634318df5 | nova-scheduler | dlp.srv.world | internal | enabled | up | 2022-05-31T02:35:00.000000 | | 1781faf9-2721-4c64-a3b0-a5b125e09095 | nova-conductor | dlp.srv.world | internal | enabled | up | 2022-05-31T02:35:02.000000 | | ae873dc3-67eb-48ea-b48d-8c660256de4d | nova-compute | dlp.srv.world | nova | enabled | up | 2022-05-31T02:35:02.000000 | +--------------------------------------+----------------+---------------+----------+---------+-------+----------------------------+ |
