　　配置安装nova compute服务
　　安装controller节点

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

　　三、安装nova服务
[root@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
[root@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
[root@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova
[root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova　　启动服务，并添加到开机启动
[root@controller ~]# systemctl enable openstack-nova-api.service   openstack-nova-consoleauth.service openstack-nova-scheduler.service   openstack-nova-conductor.service openstack-nova-novncproxy.service
[root@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
[root@compute1 ~]# yum install openstack-nova-compute　　编辑配置文件
[root@compute1 ~]#mv /etc/nova/nova.conf  /etc/nova/nova.conf_bak
[root@compute1 ~]#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。
[root@compute1 ~]# systemctl enable libvirtd.service openstack-nova-compute.service
[root@compute1 ~]# systemctl start libvirtd.service openstack-nova-compute.service　　

　　二、验证
　　在controller节点执行
[root@controller ~]# source /root/admin-openrc.sh
[root@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。
