1、创建nova数据库

# mysql -uroot -pChangeme_123 -e "CREATE DATABASE nova;

注意：Changeme_123为数据库root密码

2、创建数据库用户并赋予权限

# mysql -uroot -pChangeme_123 -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'Changeme_123';"

# mysql -uroot -pChangeme_123 -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'Changeme_123';"

注意：将Changeme_123替换为自己的密码

3、创建nova用户及赋予admin权限

# source /root/admin-openrc.sh

# openstack user create  nova  --password Changeme_123

# openstack role add --project service --user nova admin

注意：将Changeme_123替换为自己的密码

4、创建computer服务

# openstack service create --name nova --description "OpenStack Compute" compute

5、创建nova的endpoint

# openstack endpoint create --region RegionOne   compute public http://${HOSTNAME}:8774/v2/%\(tenant_id\)s  

# openstack endpoint create --region RegionOne   compute internal http://${HOSTNAME}:8774/v2/%\(tenant_id\)s  

# openstack endpoint create --region RegionOne   compute admin http://${HOSTNAME}:8774/v2/%\(tenant_id\)s

6、安装nova相关软件

# yum install openstack-nova-api openstack-nova-cert   openstack-nova-conductor openstack-nova-console   openstack-nova-novncproxy openstack-nova-scheduler   python-novaclient -y

7、配置nova的配置文件/etc/nova/nova.conf

# openstack-config --set  /etc/nova/nova.conf database connection  mysql://nova:Changeme_123@${HOSTNAME}/nova

# openstack-config --set  /etc/nova/nova.conf DEFAULT rpc_backend  rabbit

# openstack-config --set  /etc/nova/nova.conf oslo_messaging_rabbit rabbit_host  ${HOSTNAME}

# openstack-config --set  /etc/nova/nova.conf oslo_messaging_rabbit rabbit_userid  openstack  

# openstack-config --set  /etc/nova/nova.conf oslo_messaging_rabbit rabbit_password  Changeme_123

# openstack-config --set  /etc/nova/nova.conf DEFAULT auth_strategy  keystone

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken auth_uri  http://${HOSTNAME}:5000

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken auth_url  http://${HOSTNAME}:35357

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken auth_plugin  password

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken project_domain_id  default

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken user_domain_id  default

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken project_name  service

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken username  nova

# openstack-config --set  /etc/nova/nova.conf keystone_authtoken password  Changeme_123

# openstack-config --set  /etc/nova/nova.conf DEFAULT my_ip ETH0_IP  

# openstack-config --set  /etc/nova/nova.conf DEFAULT verbose  True

# openstack-config --set  /etc/nova/nova.conf DEFAULT network_api_class  nova.network.neutronv2.api.API

# openstack-config --set  /etc/nova/nova.conf DEFAULT security_group_api  neutron

# openstack-config --set  /etc/nova/nova.conf DEFAULT linuxnet_interface_driver  nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver

# openstack-config --set  /etc/nova/nova.conf DEFAULT firewall_driver  nova.virt.firewall.NoopFirewallDriver

# openstack-config --set  /etc/nova/nova.conf vnc vncserver_listen  ETH0_IP  

# openstack-config --set  /etc/nova/nova.conf vnc vncserver_proxyclient_address  ETH0_IP

# openstack-config --set  /etc/nova/nova.conf vnc  novncproxy_base_url  http://ETH0_IP:6080/vnc_auto.html

# openstack-config --set  /etc/nova/nova.conf glance host  controller

# openstack-config --set  /etc/nova/nova.conf oslo_concurrency lock_path  /var/lib/nova/tmp

# openstack-config --set  /etc/nova/nova.conf DEFAULT enabled_apis osapi_compute,metadata

注意，替换ETH0_IP为eth0的IP，一共四处。

8、同步nova数据

# su -s /bin/sh -c "nova-manage db sync" nova

9、启动nova服务并设置开机启动

# systemctl enable openstack-nova-api.service   openstack-nova-cert.service openstack-nova-consoleauth.service  openstack-nova-scheduler.service openstack-nova-conductor.service   openstack-nova-novncproxy.service

# systemctl start openstack-nova-api.service   openstack-nova-cert.service openstack-nova-consoleauth.service  openstack-nova-scheduler.service openstack-nova-conductor.service   openstack-nova-novncproxy.service

10、安装openstack-nova-compute和 sysfsutils服务

# yum install openstack-nova-compute sysfsutils -y

11、配置nova配置文件

如果操作系统安装在物理机上做如下配置

# openstack-config --set  /etc/nova/nova.conf libvirt virt_type  kvm

如果操作系统安装在虚拟机上做如下配置

# openstack-config --set  /etc/nova/nova.conf libvirt virt_type  qemu

12、启动computer服务及设置开机启动

# systemctl enable libvirtd.service openstack-nova-compute.service

# systemctl start libvirtd.service openstack-nova-compute.service

13、验证nova服务

# source /root/admin-openrc.sh

# nova service-list

# nova endpoints

# nova image-list
