OpenStack Victoria : Configure Nova #32021/08/31 |
Install OpenStack Compute Service (Nova).
This example is based on the emvironment like follows.
If you'd like to install Nova Compute on another Host, refer to here. eth0|10.0.0.30 +-----------+-----------+ | [ Control Node ] | | | | MariaDB RabbitMQ | | Memcached httpd | | Keystone Glance | | Nova API,Compute | +-----------------------+ |
[1] |
Install KVM HyperVisor on Compute 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)#
apt -y install nova-compute nova-compute-kvm # on Debian 11 default is set cgroup v2, however, # specific feature does not work on Nova-Compute, so fall back to cgroup v1 root@dlp ~(keystone)# vi /etc/default/grub # line 10 : add GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet" GRUB_CMDLINE_LINUX=" systemd.unified_cgroup_hierarchy=false systemd.legacy_systemd_cgroup_controller=false "
root@dlp ~(keystone)#
root@dlp ~(keystone)# update-grub
reboot

[3] | In addition to basic settings of Nova, add following settings. |
root@dlp ~(keystone)#
vi /etc/nova/nova.conf # 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
root@dlp ~(keystone)#
vi /etc/default/nova-consoleproxy # line 6 : change NOVA_CONSOLE_PROXY_TYPE= novnc

[4] | Start Nova Compute service. |
root@dlp ~(keystone)#
systemctl restart nova-compute nova-novncproxy root@dlp ~(keystone)# systemctl enable nova-compute nova-novncproxy
# discover Compute Node root@dlp ~(keystone)# su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"
