计算节点和控制节点时间同步
yum install -y ntpdate
ntpdate time1.aliyun.com
****计算节点操作****
yum install openstack-nova-compute -y
****控制节点操作****
复制控制节点主机(192.168.2.11)的配置文件到计算节点的主机
scp /etc/nova/nova.conf 192.168.2.12:/etc/nova/
****计算节点操作****
vim /etc/nove/nove.conf
[api_database]

#删除

确定您的计算节点是否支持虚拟机的硬件加速:
egrep -c '(vmx|svm)' /proc/cpuinfo
#结果为1就是支持
#结果为0就是不支持
#如果此命令返回值0,则您的计算节点不支持硬件加速,您必须配置libvirt为使用QEMU而不是KVM。
编辑文件中的[libvirt]部分,/etc/nova/nova.conf如下所示
[libvirt]
#...
#打开注释并修改
virt_type = qemu
注意:生产场景用(物理环境)kvm
systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service
