OpenStack 学习笔记(五)：OpenStack nova服务搭建
——先决条件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
# 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
# openstack role add --project service --user nova admin
4.）Create the nova service entity
# 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
# 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 |
+--------------+------------------------------------------------+
# 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 |
+--------------+------------------------------------------------+
# openstack endpoint create --region RegionOne compute admin http://192.168.100.120:8774/v2.1/%\(tenant_id\)s
+--------------+------------------------------------------------+
| Field | Value |
+--------------+------------------------------------------------+

——控制节点nova服务搭建配置
6.）安装nova服务
# yum -y install openstack-nova-api openstack-nova-cert openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler python-novaclient
7.）配置nova服务
# cp /etc/nova/nova.conf /etc/nova/nova.conf.bak
# vim /etc/nova/nova.conf

+--------------------------------------------+ 9.）Start the Compute services and configure start when the system boots
9.1） configure start when the system boots
# systemctl enable \
openstack-nova-api.service \
openstack-nova-consoleauth.service \
openstack-nova-scheduler.service \
openstack-nova-conductor.service \
openstack-nova-novncproxy.service
9.2）start compute service
# systemctl start \
openstack-nova-api.service \
openstack-nova-consoleauth.service \
openstack-nova-scheduler.service \
openstack-nova-conductor.service \
openstack-nova-novncproxy.service
9.2）select compute service status
# systemctl status \
openstack-nova-api.service \
openstack-nova-consoleauth.service \
openstack-nova-scheduler.service \
openstack-nova-conductor.service \
openstack-nova-novncproxy.service

——计算节点nova服务搭建配置
1.同步时间
# hostnamectl set-hostname OpenStack-Compute
# su -
# ntpdate pool.ntp.org 2.添加mitaka源
# wget https://repos.fedorapeople.org/repos/openstack/openstack-mitaka/rdo-release-mitaka-3.noarch.rpm
# yum install -y centos-release-openstack-mitaka
# yum install -y rdo-release-mitaka-3.noarch.rpm
# yum upgrade -y 3.添加hosts解析
# echo -e "192.168.100.120\topenstack" >> /etc/hosts
# echo -e "192.168.100.121\t$(uname -n)" >> /etc/hosts
# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.254.140 openstack
192.168.254.141 OpenStack-Computee 4.安装配置compute
# yum install -y openstack-nova-compute
# cp /etc/nova/nova.conf/etc/nova/nova.conf.bak
# vim /etc/nova/nova.conf

5530:novncproxy_base_url=http://192.168.254.140:6080/vnc_auto.html
5.）查看硬件是否支持kvm
# egrep -c '(vmx|svm)' /proc/cpuinfo
1 6.）start libvirtd and openstack-nova-compute
# systemctl enable libvirtd.service openstack-nova-compute.service
# 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
# openstack compute service list
