nova计算节点部署

第一步：安装依赖包
[root@zxw7 openstack-compute-yilai]# ls
qemu-img-ev-2.9.0-16.el7_4.8.1.x86_64.rpm
qemu-kvm-common-ev-2.9.0-16.el7_4.8.1.x86_64.rpm
qemu-kvm-ev-2.9.0-16.el7_4.8.1.x86_64.rpm
[root@zxw7 openstack-compute-yilai]# yum localinstall ./*

第二步：下载nova-compute服务
[root@zxw7 ~]# yum install openstack-nova-compute -y

第二步：配置nova的文件

[root@zxw7 ~]# cat /etc/nova/nova.conf | grep -v "^#" | grep -v "^$"

第四步：查看cpu是否开启
[root@zxw7 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo

第五步：启动服务并开机自启
yum update librbd1
[root@zxw7 ~]# systemctl start libvirtd.service openstack-nova-compute.service
[root@zxw7 ~]# systemctl enable libvirtd.service openstack-nova-compute.service

zxw6：查看虚拟化状态
[root@zxw6 images]# openstack hypervisor list
+----+---------------------+-----------------+---------------+-------+

| 2 | zxw8 | QEMU | 192.168.126.6 | up |

发现加入节点
[root@zxw6 images]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

[scheduler]
discover_hosts_in_cells_interval = 300

[root@zxw6 images]# openstack compute service list 计算节点
