手动部署OpenStack Rocky双节点

Nova (controller)

关闭防火墙

[tony@controller ~]$ sudo systemctl stop firewalld
[tony@controller ~]$ sudo systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

设置admin的鉴权信息

[tony@controller ~]$ cat adminrc
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=$password
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

[tony@controller ~]$ source adminrc

添加Nova账户及其鉴权信息

创建compute类型的服务

[tony@controller ~]$ openstack service create --name nova --description "OpenStack Compute" compute
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Compute                |
| enabled     | True                             |

| type        | compute                          |
+-------------+----------------------------------+

创建nova账户并设置密码

[tony@controller ~]$ openstack user create --domain default --password-prompt nova

User Password: <Enter password>
Repeat User Password: <Repeat password>
±--------------------±---------------------------------+
| Field | Value |
±--------------------±---------------------------------+
| domain_id | default |

初始化Nova API与Placement数据库

[tony@controller ~]$ sudo su -s /bin/sh -c "nova-manage api_db sync" nova

初始化Nova数据库

[tony@controller ~]$ sudo su -s /bin/sh -c "nova-manage db sync" nova

注：第一次执行本步骤，可以忽略下面的注释
后续步骤中 $sudo nova-status upgrade check 命令报错，又重新初始化了一次数据库，就没有第一个红色的Warning了。nova-status命令也正常执行了。具体原因待查。
