篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了OpenStack-liberty版Nova计算节点部署服务部署相关的知识，希望对你有一定的参考价值。

Nova Compute：

nova-compute 一般运行在计算节点上，通过Message Queue接收并管理VM的生命周期。
Nova-compute通过Libvirt管理KVM，通过XenAPI管理Xen等。

node2:
修改主机名：注意：修改主机名，以后不能更改。
[[email protected] ~]# hostname linux-node2.smoke.com

[[email protected] ~]# vim /etc/hostname
hostname linux-node2.smoke.com

网卡配置：

[[email protected] ~]# ifconfig

添加hosts文件：

[[email protected] ~]# vim /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.56.11   linux-node1 linux-node1.smoke.com
192.168.56.12   linux-node2 linux-node2.smoke.com

时间同步：会影响OpenStack正常运行，使用node1作为时间同步服务器；

[[email protected] ~]# yum -y install chrony`
[[email protected] linux-node2 ~]# cat << EOF > /etc/chrony.conf
server 192.168.56.11 iburst

设置时区：
[[email protected] ~]# timedatectl set-timezone Asia/Shanghai

[[email protected] ~]# date
2018年 09月 30日 星期日 22:33:55 CST

安装nova：
这里还是使用vault.centos的yum源；

[[email protected] ~]# vim /etc/yum.repos.d/openstack_liberty.repo 
[openstack-liberty]
name=openstack-liberty
baseurl=http://vault.centos.org/centos/7.3.1611/cloud/x86_64/openstack-liberty/
gpgcheck=0
gpgkey=http://vault.centos.org/RPM-GPG-KEY-CentOS-7
repo_gpgcheck=0
enabled=1

[[email protected] linux-node2 ~]# yum -y install openstack-nova-compute sysfsutils

如果使用vmwave安装需要开启cpu虚拟化支持；

查看是否支持cpu虚拟化，如果没有grep为空白，则表示不支持硬件虚拟化，需要设置服务器使支持，或者使用qemu；

[[email protected] linux-node2 ~]# grep -E ‘vmx|svm‘ /proc/cpuinfo

将node1的nova配置文件拷贝到node2；

启动nova-compute：

[[email protected] linux-node2 ~]# systemctl enable libvirtd.service openstack-nova-compute.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service to /usr/lib/systemd/system/openstack-nova-compute.service.

[[email protected] linux-node2 ~]# systemctl start libvirtd.service openstack-nova-compute.service

在node1验证：
