# 将计算节点增加到cell数据库 #

## 1.控制节点查看nova-compute服务 ##

先加载环境变量脚本`source /admin-openrc.sh`

source admin-openrc.sh

openstack compute service list
    openstack compute service list --service nova-compute

## 2.同步计算节点 ##

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

设置发现间隔时间，编辑`vim /etc/nova/nova.conf`文件。在之后添加新的更多的计算节点时，必须在控制器节点上运行上述两个命令，以在控制节点注册增加这些新的计算节点。另外，您可以在控制节点`/etc/nova/nova.conf`中，设置新节点自动注册的任务。

crudini --set /etc/nova/nova.conf scheduler discover_hosts_in_cells_interval 300

此时再执行`nova service-list`命令，和之前`6.1部署文档`相比会多出2个compute服务:

安装完毕，接下来需要进行测试，检查计算服务的状态

# 验证计算服务的运行 #

## 1.加载环境变量 ##

cd 
    source admin-openrc.sh

## 2.列出服务组件 ##

以验证每个进程的成功启动和注册

openstack compute service list

此输出应指示在控制器节点上启用的两个服务组件和在计算节点上启用的一个服务组件。

## 3.列出身份服务中的API端点 ##

以验证与身份服务的连接性

openstack catalog list

注意：端点列表可能会有所不同，具体取决于OpenStack组件的安装。忽略此输出中的任何警告。

## 4.在镜像服务中列出镜像列表 ##

以验证与镜像服务的连接性

openstack image list

## 5.检查nova各组件的状态 ##

检查placement API和cell服务是否正常工作

nova-status upgrade check

报错处理

[root@controller ~]# nova-status upgrade check
    Error:
    Traceback (most recent call last):
      File "/usr/lib/python3.6/site-packages/nova/cmd/status.py", line 495, in main
        ret = fn(*fn_args, **fn_kwargs)
      File "/usr/lib/python3.6/site-packages/oslo_upgradecheck/upgradecheck.py", line 102, in check
        result = func(self)
      File "/usr/lib/python3.6/site-packages/nova/cmd/status.py", line 164, in _check_placement
        versions = self._placement_get("/")
      File "/usr/lib/python3.6/site-packages/nova/cmd/status.py", line 154, in _placement_get
        return client.get(path, raise_exc=True).json()
      File "/usr/lib/python3.6/site-packages/keystoneauth1/adapter.py", line 395, in get
        return self.request(url, 'GET', **kwargs)
      File "/usr/lib/python3.6/site-packages/keystoneauth1/adapter.py", line 257, in request
        return self.session.request(url, method, **kwargs)
      File "/usr/lib/python3.6/site-packages/keystoneauth1/session.py", line 976, in request
        raise exceptions.from_response(resp, method, url)
    keystoneauth1.exceptions.http.Forbidden: Forbidden (HTTP 403)

解决

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

在`#SSLCertificateKeyFile`底下添加

#Placement API
    <Directory /usr/bin>
       <IfVersion >= 2.4>
          Require all granted
       </IfVersion>
       <IfVersion < 2.4>
          Order allow,deny
          Allow from all
       </IfVersion>
    </Directory>

重启httpd服务

[root@controller ~]# systemctl restart httpd
    [root@controller ~]# nova-status upgrade check
    JSON formatted policy_file support is deprecated since Victoria release. You need to use YAML format which will be default in future.

# 控制节点Nova计算服务验证完成 #

至此，在控制节点和计算节点，完成nova计算服务的安装，并添加到OpenStack集群中。

新的计算节点加入时，需要将计算节点安装和控制节点验证都需要进行安装。

使用VMware虚拟机的话，控制节点和各个计算节点，现在可以关机做快照。
