五:实现Nova-computepOs拜客生活常识网

1) 安装Nova-Compute
[email protected]:~(keystone)# apt install qemu-kvm libvirt-daemon-system libvirt-daemon virtinst bridge-utils libosinfo-bin nova-compute nova-compute-kvm -y

2) 配置VNC(便于后续直接通过浏览器控制实例)
[email protected]:~(keystone)# vim /etc/nova/nova.conf
......
......
......
......
......
......

# 找到 [VNC] 区段，添加如下内容
[vnc]
enabled = True
server_listen = srv1.1000y.cloud
server_proxyclient_address = srv1.1000y.cloud
novncproxy_host = 127.0.0.1
novncproxy_port = 6080
novncproxy_base_url = https://srv1.1000y.cloud:6080/vnc_auto.html

......
......
......
......
......
......

[email protected]:~(keystone)# systemctl restart nova-compute

[email protected]:~(keystone)# su -s /bin/bash nova -c "nova-manage cell_v2 discover_hosts"

[email protected]:~(keystone)# openstack compute service list

六:扩展NovaCompute节点pOs拜客生活常识网

1) 准备第2台节点: 8G 4core

2) 在扩展的计算节点上安装KVM并启动
[email protected]:~# apt install qemu-kvm libvirt-daemon-system libvirt-daemon virtinst 
bridge-utils libosinfo-bin -y

[email protected]:~# lsmod | grep kvm
kvm_intel             372736  0
kvm                  1028096  1 kvm_intel

3) 安装Nova-Compute
[email protected]:~# apt install software-properties-common -y
[email protected]:~# add-apt-repository cloud-archive:zed
Repository: 'deb http://ubuntu-cloud.archive.canonical.com/ubuntu jammy-updates/zed main'
