继续前面的part1，将后续的compute以及network部分的安装过程记录完毕！
首先说说compute部分nova的安装。
n1。准备工作。创建数据库，配置权限！（密码依旧是openstack，还是在controller节点机器node0上操作）
1 mysql -u root -p 2 CREATE DATABASE nova; 3 GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS'; 4 GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
n2. 配置环境
1 source admin-openrc.sh
n3. 创建nova用户并添加role。
1 openstack user create --domain default --password-prompt nova 2 openstack role add --project service --user nova admin
n4.创建服务并建立endpoint。
1 openstack service create --name nova --description "OpenStack Compute" compute 2 openstack endpoint create --region RegionOne compute public http://node0:8774/v2/%\(tenant_id\)s 3 openstack endpoint create --region RegionOne compute internal http://node0:8774/v2/%\(tenant_id\)s 4 openstack endpoint create --region RegionOne compute admin http://node0:8774/v2/%\(tenant_id\)s
n5.安装组建。
1 yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient
n6.配置/etc/nova/nova.conf
1 [DEFAULT] 2 rpc_backend = rabbit 3 auth_strategy = keystone 4 my_ip = 192.168.1.100 5 network_api_class = nova.network.neutronv2.api.API 6 security_group_api = neutron 7 linuxnet_interface_driver = nova.network.linux_net.NeutronLinuxBridgeInterfaceDriver 8 firewall_driver = nova.virt.firewall.NoopFirewallDriver 9 enabled_apis=osapi_compute,metadata 10 verbose = True 11 12 [oslo_messaging_rabbit] 13 rabbit_host = node0 14 rabbit_userid = openstack 15 rabbit_password = openstack 16 17 [database] 18 connection = mysql://nova:openstack@node0/nova 19 20 [keystone_authtoken] 21 auth_uri = http://node0:5000 22 auth_url = http://node0:35357 23 auth_plugin = password 24 project_domain_id = default 25 user_domain_id = default 26 project_name = service 27 username = nova 28 password = openstack 29 30 [vnc] 31 vncserver_listen = $my_ip 32 vncserver_proxyclient_address = $my_ip 33 34 [glance] 35 host = node0 36 37 [oslo_concurrency] 38 lock_path = /var/lib/nova/tmp
n7. 同步数据库
1 su -s /bin/sh -c "nova-manage db sync" nova
n8. 启动服务
1 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 2 3 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
在这一步遇到了错误，主要是systemctl start openstack-nova-api.service的错误，没有权限！错误信息如下：
