OpenStack-T版nova服务

nova 服务

控制节点

创建数据库

使用数据库访问客户端以用户身份连接到数据库服务器：root

#mysql -u root -p000000

创建数据库

>CREATE DATABASE nova_api; 
>CREATE DATABASE nova; 
>CREATE DATABASE nova_cell0;

授予对数据库的正确访问权限：

> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost'    IDENTIFIED BY '000000';
> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%'    IDENTIFIED BY '000000';

> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost'    IDENTIFIED BY '000000';
> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%'    IDENTIFIED BY '000000';

> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost'    IDENTIFIED BY '000000';
> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%'    IDENTIFIED BY '000000';

# flush privileges;  

退出数据库

获取凭据以获取对仅限管理员的 CLI 命令的访问权限：admin

#. admin-openrc

创建用户：nova

#openstack user create --domain default --password 000000 nova

将角色添加到用户

#openstack role add --project service --user nova admin

创建服务实体：nova

#openstack service create --name nova \
   --description "OpenStack Compute" compute

创建Compute API服务端点

#openstack endpoint create --region RegionOne \
   compute public http://controller:8774/v2.1
#openstack endpoint create --region RegionOne \
   compute internal http://controller:8774/v2.1
#openstack endpoint create --region RegionOne \
   compute admin http://controller:8774/v2.1

安装和配置组件

安装软件包

#yum install openstack-nova-api openstack-nova-conductor \
   openstack-nova-novncproxy openstack-nova-scheduler -y

编辑配置文件

#vim /etc/nova.conf

填充数据库：nova-api

#su -s /bin/sh -c "nova-manage api_db sync" nova

注册数据库：cell0

#su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

创建单元格：cell1

#su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

填充 nova 数据库：

#su -s /bin/sh -c "nova-manage db sync" nova

验证 nova 单元格 0 和单元格 1 是否已正确注册：

#su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

启动计算服务并将其配置为在系统启动时启动：

# systemctl enable \
     openstack-nova-api.service \
     openstack-nova-scheduler.service \
     openstack-nova-conductor.service \
     openstack-nova-novncproxy.service 
# systemctl restart \
     openstack-nova-api.service \
     openstack-nova-scheduler.service \
     openstack-nova-conductor.service \
     openstack-nova-novncproxy.service
# curl http://controller:8774

将计算节点添加到单元数据库

控制节点

获取管理员凭据以启用仅限管理员的 CLI 命令，然后确认数据库中存在计算主机：

#. admin-openrc
#openstack compute service list --service nova-compute

发现计算主机：

#su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

---

验证操作

控制节点

获取凭据以获取对仅限管理员的 CLI 命令的访问权限：admin

#. admin-openrc

列出服务组件以验证每个进程是否成功启动和注册：

#openstack compute service list

列出标识服务中的 API 终结点，以验证与标识服务的连接：

#openstack catalog list

列出影像服务中的图像以验证与影像服务的连通性：

#openstack image list

检查单元和放置 API 是否成功工作，以及其他必要的先决是否到位

#nova-status upgrade check
