nova作为计算组件,在控制节点和计算节点都需要安装

1、创建用户:nova,并授权用户权限

[[email protected] ~]# source admin-openrc.sh
[[email protected] ~]# openstack user create --domain default --password=nova nova
+-----------+----------------------------------+
| Field     | Value                            |
+-----------+----------------------------------+

| name      | nova                             |
+-----------+----------------------------------+
[[email protected] ~]# openstack role add --project service --user nova admin

2、在keystone上面注册nova

[[email protected] ~]# openstack service create --name nova --description "OpenStack Compute" compute

2884:rabbit_password=openstack
3309:vncserver_listen= $my_ip
3310:vncserver_proxyclient_address= $my_ip


4、同步数据库,检查结果

[[email protected] nova]# su -s /bin/sh -c "nova-manage db sync" nova
[[email protected] nova]# mysql -e "use nova;show tables"

5、启动nova

[[email protected] nova]# 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
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-api.service to /usr/lib/systemd/system/openstack-nova-api.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-cert.service to /usr/lib/systemd/system/openstack-nova-cert.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-consoleauth.service to /usr/lib/systemd/system/openstack-nova-consoleauth.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service to /usr/lib/systemd/system/openstack-nova-scheduler.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service to /usr/lib/systemd/system/openstack-nova-conductor.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service to /usr/lib/systemd/system/openstack-nova-novncproxy.service.
[[email protected] nova]# 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

6、在计算节点上面操作

[[email protected] ~]# vim /etc/chrony.conf
server 172.16.80.130 iburst

[[email protected] ~]# systemctl enable chronyd.service
[[email protected] ~]# systemctl start  chronyd.service

[[email protected] ~]# timedatectl set-timezone Asia/Shanghai
[[email protected] ~]# timedatectl status
      Local time: Wed 2016-11-02 19:36:16 CST
  Universal time: Wed 2016-11-02 11:36:16 UTC
        RTC time: Wed 2016-11-02 11:36:16
        Timezone: Asia/Shanghai (CST, +0800)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a


7、安装nova组件并配置

[[email protected] ~]# yum install https://rdoproject.org/repos/openstack-liberty/rdo-release-liberty.rpm -y
[[email protected] ~]# yum install centos-release-openstack-liberty -y
[[email protected] ~]# yum install openstack-nova-compute sysfsutils -y

[[email protected] nova]# grep -n ‘^[a-Z]‘ /etc/nova/nova.conf 
198:my_ip=172.16.80.131
344:enabled_apis=osapi_compute,metadata
506:auth_strategy=keystone
838:network_api_class=nova.network.neutronv2.api.API
930:linuxnet_interface_driver=nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver

2125:project_domain_id = default
2126:user_domain_id = default
2127:project_name = service
2128:username = nova
2129:password = nova
2309:virt_type=kvm
2738:lock_path=/var/lib/nova/tmp
2881:rabbit_host=172.16.80.130
2882:rabbit_port=5672
2883:rabbit_userid=openstack
2884:rabbit_password=openstack
3309:novncproxy_base_url=http://172.16.80.130:6080/vnc_auto.html
3311:vncserver_listen= 0.0.0.0
3312:vncserver_proxyclient_address= $my_ip
3313:vnc_enabled=true

8、启动

[[email protected] nova]# systemctl enable libvirtd openstack-nova-compute
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] nova]# systemctl start libvirtd openstack-nova-compute

9、在控制节点上面进行验证
