五：OPENSTACK Queens部署computer计算服务

Posted 2021-04-24 MisterChen

备注：在控制节点操作

• 添加数据库以及用户

[root@controller ~]# mysql -u root -p

create database nova_api;

create database nova;

create database nova_cell0;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '123456';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '123456';

• 创建nova用户

[root@controller ~]# openstack user create --domain default --password-prompt nova

• 将nova用户加入admin和server

[root@controller ~]# openstack role add --project service --user nova admin

• 创建计算项目和接口API

[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

[root@controller ~]# openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1

• 创建placement用户，并将用户加入server和admin，并创建项目和接口

[root@controller ~]# openstack user create --domain default --password-prompt placement

[root@controller ~]# openstack role add --project service --user placement admin

[root@controller ~]# openstack service create --name placement --description "Placement API" placement

[root@controller ~]# openstack endpoint create --region RegionOne placement public http://controller:8778

[root@controller ~]# openstack endpoint create --region RegionOne placement internal http://controller:8778

• 安装nova相关包

[root@controller ~]# yum install -y openstack-nova-api openstack-nova-conductor   openstack-nova-console openstack-nova-novncproxy   openstack-nova-scheduler openstack-nova-placement-api

• 编辑配置文件nova.conf

[root@controller ~]# vim /etc/nova/nova.conf

[DEFAULT]

enabled_apis = osapi_compute,metadata

transport_url = rabbit://openstack:123456@controller

my_ip = 192.168.1.110

use_neutron = True

firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api_database]

connection = mysql+pymysql://nova:123456@controller/nova_api

[database]

connection = mysql+pymysql://nova:123456@controller/nova

[api]

auth_strategy = keystone

[vnc]

enabled = true

server_listen = $my_ip

server_proxyclient_address = $my_ip

[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 = 123456

[glance]

api_servers = http://controller:9292

[oslo_concurrency]

lock_path = /var/lib/nova/tmp

[placement]

os_region_name = RegionOne

project_domain_name = Default

project_name = service

auth_type = password

user_domain_name = Default

auth_url = http://controller:35357/v3

username = placement

password = 123456

• 编辑配置文件00-nova-placement-api.conf，在末尾添加

[root@controller ~]# vim /etc/httpd/conf.d/00-nova-placement-api.conf

<Directory /usr/bin>

   <IfVersion >= 2.4>

      Require all granted

   </IfVersion>

   <IfVersion < 2.4>

      Order allow,deny

      Allow from all

   </IfVersion>

</Directory>

• 重新启动httpd服务

[root@controller ~]# systemctl restart httpd

• 同步api数据库

[root@controller ~]# su -s /bin/sh -c "nova-manage api_db sync" nova

• 同步cell0数据库

[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

• 创建cell1

[root@controller ~]# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

• 同步nova数据库

[root@controller ~]# su -s /bin/sh -c "nova-manage db sync" nova

• 确认cell0和cell1

[root@controller ~]# nova-manage cell_v2 list_cells

• 启动nova服务

[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
