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
