1.同步时间
5.）查看硬件是否支持kvm
7.）校验检查
7.1）在控制节点检查compute注册信息和状态
1.）创建数据库
MariaDB [(none)]> CREATE DATABASE nova; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]> GRANT ALL ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.00 sec)MariaDB [(none)]> CREATE DATABASE nova_api;Query OK, 1 row affected (0.00 sec)MariaDB [(none)]> GRANT ALL ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.02 sec)MariaDB [(none)]> GRANT ALL ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.02 sec)2.）Create the nova user
[root@openstack ~]# openstack user create --domain default --password nova nova +-----------+----------------------------------+ | Field | Value | +-----------+----------------------------------+ | domain_id | 0b741c2e67ed4d618fa7e963325221ad | | enabled | True | | id | f059f5d68d8441f2ac506701c972221e | | name | nova | +-----------+----------------------------------+
3.）Add the admin role to the nova user
[root@openstack ~]# openstack role add --project service --user nova admin
4.）Create the nova service entity
[root@openstack ~]# openstack service create --name nova --description "OpenStack Compute" compute +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Compute | | enabled | True | | id | 6276582dd78040cbb125db6793bdfe5d | | name | nova | | type | compute | +-------------+----------------------------------+5.）Create the Compute service API endpoints
[root@openstack ~]# openstack endpoint create --region RegionOne compute public http://192.168.100.120:8774/v2.1/%\(tenant_id\)s +--------------+------------------------------------------------+ | Field | Value | +--------------+------------------------------------------------+ | enabled | True | | id | 4982a6ccbef244148e6c15992a56185f | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 6276582dd78040cbb125db6793bdfe5d | | service_name | nova | | service_type | compute | | url | http://192.168.100.120:8774/v2.1/%(tenant_id)s | +--------------+------------------------------------------------+ [root@openstack ~]# openstack endpoint create --region RegionOne compute internal http://192.168.100.120:8774/v2.1/%\(tenant_id\)s +--------------+------------------------------------------------+ | Field | Value | +--------------+------------------------------------------------+ | enabled | True | | id | 8a96cff800914256b6049e2d5e8ca913 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 6276582dd78040cbb125db6793bdfe5d | | service_name | nova | | service_type | compute | | url | http://192.168.100.120:8774/v2.1/%(tenant_id)s | +--------------+------------------------------------------------+ [root@openstack ~]# openstack endpoint create --region RegionOne compute admin http://192.168.100.120:8774/v2.1/%\(tenant_id\)s +--------------+------------------------------------------------+ | Field | Value | +--------------+------------------------------------------------+ | enabled | True | | id | 2dfbc5fcf3204aa9a7930024eaa90899 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 6276582dd78040cbb125db6793bdfe5d | | service_name | nova | | service_type | compute | | url | http://192.168.100.120:8774/v2.1/%(tenant_id)s | +--------------+------------------------------------------------+

1.同步时间
[root@OpenStack-Compute ~]# hostnamectl set-hostname OpenStack-Compute [root@OpenStack-Compute ~]# su - [root@OpenStack-Compute ~]# ntpdate pool.ntp.org2.添加mitaka源
[root@OpenStack-Compute ~]# wget https://repos.fedorapeople.org/repos/openstack/openstack-mitaka/rdo-release-mitaka-3.noarch.rpm [root@OpenStack-Compute ~]# yum install -y centos-release-openstack-mitaka [root@OpenStack-Compute ~]# yum install -y rdo-release-mitaka-3.noarch.rpm [root@OpenStack-Compute ~]# yum upgrade -y3.添加hosts解析

5.）查看硬件是否支持kvm
[root@OpenStack-Compute ~]# egrep -c '(vmx|svm)' /proc/cpuinfo 16.）start libvirtd and openstack-nova-compute
[root@OpenStack-Compute ~]# systemctl enable libvirtd.service openstack-nova-compute.service [root@OpenStack-Compute ~]# systemctl start libvirtd.service openstack-nova-compute.service
7.）校验检查
7.1）在控制节点检查compute注册信息和状态
