Openstack（十）部署nova服务（计算节点）
在计算节点安装
10.1安装nova计算服务
# 阿里云源详见2.3配置
# yum install openstack-nova-compute
10.2配置nova计算服务
10.2.1配置nova.conf
# vim /etc/nova/nova.conf

10.2.2确认计算节点是否支持硬件加速
# egrep -c '(vmx|svm)' /proc/cpuinfo
40
10.3启动nova计算服务并设置为开机启动
# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service
10.4添加计算服务到cell数据库
# 在控制端配置
# source admin-openstack.sh
#定期主动发现：
# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
# openstack hypervisor list
+----+-------------------------+-----------------+----------------+-------+

| 1 | linux-host2.exmaple.com | QEMU | 192.168.10.202 | up |
+----+-------------------------+-----------------+----------------+-------+
# 设置定期主动发现
# vim /etc/nova/nova.conf
8577 [scheduler]
8684 discover_hosts_in_cells_interval=300
#重启nova服务
# bash nova- restart.sh
10.5验证计算节点
# nova host-list
# nova service-list
# openstack image list
# openstack compute service list
#列出服务组件是否成功注册
# nova-status upgrade check
# openstack catalog list
#列出keystone服务中的端点，以验证keystone的连通性
