配置安装nova compute服务
安装controller节点

一、创建nova数据库

1 2 3 4 5 6 7

[iyunv@controller ~]# mysql -u root -p >>CREATE DATABASE nova_api; >>CREATE DATABASE nova; >>GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost'   IDENTIFIED BY 'NOVA_DBPASS'; >>GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%'   IDENTIFIED BY 'NOVA_DBPASS'; >>GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost'   IDENTIFIED BY 'NOVA_DBPASS'; >>GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%'   IDENTIFIED BY 'NOVA_DBPASS';

NOVA_DBPASS改为自己要设置的密码

二、创建服务实体和api接口

1 2 3 4 5 6 7

[iyunv@controller ~]#source /root/admin-openrc.sh [iyunv@controller ~]# openstack user create --domain default   --password-prompt nova [iyunv@controller ~]# openstack role add --project service --user nova admin [iyunv@controller ~]# openstack service create --name nova  --description "OpenStack Compute" compute [iyunv@controller ~]# openstack endpoint create --region RegionOne   compute public [iyunv@controller ~]# openstack endpoint create --region RegionOne   compute internal http://controller:8774/v2.1/%\(tenant_id\)s [iyunv@controller ~]# openstack endpoint create --region RegionOne   compute admin http://controller:8774/v2.1/%\(tenant_id\)s

三、安装nova服务

1	[iyunv@controller ~]# yum install openstack-nova-api openstack-nova-conductor   openstack-nova-console openstack-nova-novncproxy  openstack-nova-scheduler

编辑nova服务配置文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37

[iyunv@controller ~]# mv /etc/nova/nova.conf  /etc/nova/nova.conf_bak [DEFAULT] enabled_apis = osapi_compute,metadata rpc_backend = rabbit auth_strategy = keystone my_ip = 10.0.0.11 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver [api_database] connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api  #改为自己数据库的密码 [database] connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova   #改为自己数据库的密码 [oslo_messaging_rabbit] rabbit_host = controller rabbit_userid = openstack rabbit_password = RABBIT_PASS   #改为自己rabbitmq的密码 [keystone_authtoken] auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = NOVA_PASS   #改为自己nova服务的密码 [vnc] vncserver_listen = $my_ip vncserver_proxyclient_address = $my_ip [glance] api_servers = http://controller:9292 [oslo_concurrency] lock_path = /var/lib/nova/tmp

同步数据库

1 2	[iyunv@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova [iyunv@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova

启动服务，并添加到开机启动

1 2

[iyunv@controller ~]# systemctl enable openstack-nova-api.service   openstack-nova-consoleauth.service openstack-nova-scheduler.service   openstack-nova-conductor.service openstack-nova-novncproxy.service [iyunv@controller ~]# systemctl start openstack-nova-api.service   openstack-nova-consoleauth.service openstack-nova-scheduler.service   openstack-nova-conductor.service openstack-nova-novncproxy.service

安装compute节点
一、安装nova服务

1	[iyunv@controller ~]# yum install openstack-nova-compute

编辑配置文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

[iyunv@controller ~]#mv /etc/nova/nova.conf  /etc/nova/nova.conf_bak [iyunv@controller ~]#vim /etc/nova/nova.conf [DEFAULT] rpc_backend = rabbit auth_strategy = keystone my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS  #填写本机的管理ip，就是10.0.0段的 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver [oslo_messaging_rabbit] rabbit_host = controller rabbit_userid = openstack rabbit_password = RABBIT_PASS   #填写你rabbit的密码 [keystone_authtoken] auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = NOVA_PASS    #填写你nova服务的密码 [vnc] enabled = True vncserver_listen = 0.0.0.0 vncserver_proxyclient_address = $my_ip novncproxy_base_url = [glance] api_servers = http://controller:9292 [oslo_concurrency] lock_path = /var/lib/nova/tmp [libvirt] virt_type = qemu  #在命令行执行egrep -c '(vmx|svm)' /proc/cpuinfo 如果返回0，就是qemu 如果是1，就 是kvm

启动nova相关服务，并加入开机启动。

1 2	[iyunv@controller ~]# systemctl enable libvirtd.service openstack-nova-compute.service [iyunv@controller ~]# systemctl start libvirtd.service openstack-nova-compute.service

二、验证
在controller节点执行

1 2 3 4 5 6 7 8 9 10 11 12

[iyunv@controller ~]# source /root/admin-openrc.sh [iyunv@controller ~]# openstack compute service list +----+------------------+------------+----------+---------+-------+----------------------------+ | Id | Binary           | Host       | Zone     | Status  | State | Updated At                 | +----+------------------+------------+----------+---------+-------+----------------------------+ |  1 | nova-consoleauth | controller | internal | enabled | up    | 2016-06-16T11:55:21.000000 | |  2 | nova-conductor   | controller | internal | enabled | up    | 2016-06-16T11:55:18.000000 | |  3 | nova-scheduler   | controller | internal | enabled | up    | 2016-06-16T11:55:25.000000 | |  6 | nova-compute     | compute1   | nova     | enabled | up    | 2016-06-16T11:55:22.000000 | |  7 | nova-compute     | compute2   | nova     | enabled | down  | 2016-06-16T08:41:19.000000 | +----+------------------+------------+----------+---------+-------+----------------------------+ 我的compute2暂时没启动所以是down状态。

出现上面信息表示成功。
