——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
[[email protected] ~]# 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
[[email protected] ~]# openstack role add --project service --user nova admin
4.）Create the nova service entity
[[email protected] ~]# 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
[[email protected] ~]# 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 | +--------------+------------------------------------------------+ [[email protected] ~]# 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 | +--------------+------------------------------------------------+ [[email protected] ~]# 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 | +--------------+------------------------------------------------+

——计算节点nova服务搭建配置
1.同步时间
[[email protected] ~]# hostnamectl set-hostname OpenStack-Compute [[email protected] ~]# su - [[email protected] ~]# ntpdate pool.ntp.org
2.添加mitaka源
[[email protected] ~]# wget https://repos.fedorapeople.org/repos/openstack/openstack-mitaka/rdo-release-mitaka-3.noarch.rpm [[email protected] ~]# yum install -y centos-release-openstack-mitaka [[email protected] ~]# yum install -y rdo-release-mitaka-3.noarch.rpm [[email protected] ~]# yum upgrade -y
3.添加hosts解析
[[email protected] ~]# echo -e "192.168.100.120\topenstack" >> /etc/hosts [[email protected] ~]# echo -e "192.168.100.121\t$(uname -n)" >> /etc/hosts [[email protected] ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.254.140 openstack 192.168.254.141 OpenStack-Computee
4.安装配置compute
[[email protected] ~]# yum install -y openstack-nova-compute [[email protected] ~]# cp /etc/nova/nova.conf /etc/nova/nova.conf.bak [[email protected] ~]# vim /etc/nova/nova.conf 1:[DEFAULT] 141:my_ip=192.168.254.141 380:auth_strategy=keystone 1559:firewall_driver=nova.virt.firewall.NoopFirewallDriver 1682:use_neutron=true 1949:debug=true 2117:rpc_backend=rabbit 3320:[glance] 3352:api_servers=http://192.168.254.140:9292 3520:[keystone_authtoken] 3521:auth_uri = http://192.168.254.140:5000 3522:auth_url = http://192.168.254.140:35357 3523:memcached_servers = 192.168.254.140:11211 3524:auth_type = password 3525:project_domain_name = default 3526:user_domain_name = default 3527:project_name = service 3528:username = nova 3529:password = nova 4290:[oslo_concurrency] 4305:lock_path=/var/lib/nova/tmp 4401:[oslo_messaging_rabbit] 4456:rabbit_host=192.168.254.140 4462:rabbit_port=5672 4474:rabbit_userid=openstack 4478:rabbit_password=11111111 5355:[vnc] 5383:enabled=true 5425:vncserver_listen=192.168.254.140 5449:vncserver_proxyclient_address=$my_ip 5530:novncproxy_base_url=http://192.168.254.140:6080/vnc_auto.html
5.）查看硬件是否支持kvm
[[email protected] ~]# egrep -c ‘(vmx|svm)‘ /proc/cpuinfo 1
6.）start libvirtd and openstack-nova-compute
[[email protected] ~]# systemctl enable libvirtd.service openstack-nova-compute.service [[email protected] ~]# 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
[[email protected] ~]# openstack compute service list +----+------------------+--------------------+----------+---------+-------+----------------------------+ | Id | Binary | Host | Zone | Status | State | Updated At | +----+------------------+--------------------+----------+---------+-------+----------------------------+ | 1 | nova-consoleauth | openstack | internal | enabled | up | 2016-05-30T08:20:33.000000 | | 2 | nova-conductor | openstack | internal | enabled | up | 2016-05-30T08:20:32.000000 | | 3 | nova-scheduler | openstack | internal | enabled | up | 2016-05-30T08:20:33.000000 | | 7 | nova-compute | OpenStack-Computee | nova | enabled | up | 2016-05-30T08:20:29.000000 | +----+------------------+--------------------+----------+---------+-------+----------------------------+
