怎样将token认证修改为keystone认证？

要将token认证修改为keystone认证，您需要按照以下步骤进行操作：

1. 编辑glance-api.conf文件，找到[keystone_authtoken]部分，并将auth_type设置为password，如下所示：

[keystone_authtoken]
auth_type = password

2. 设置相应的认证参数，如auth_url、username、password、user_domain_name、project_domain_name等。例如：

[keystone_authtoken]
auth_type = password
auth_url = http://<keystone_host>:<keystone_port>/v3
username = <username>
password = <password>
user_domain_name = <user_domain_name>
project_domain_name = <project_domain_name>

3. 重新启动glance-api服务。

4. 确认keystone认证方式是否生效，您可以使用以下命令来验证：

glance image-list

如果返回镜像列表，则说明已经成功切换到keystone认证方式。

如何检查 OpenStack 组件的配置是否正确，如 Keystone

要检查 OpenStack 组件的配置是否正确，可以按照以下步骤操作：

1. 连接到运行 Keystone 组件的 OpenStack 控制节点。
2. 打开 Keystone 的配置文件 /etc/keystone/keystone.conf。
3. 检查配置文件中的各个选项是否正确设置。这些选项包括数据库连接、认证后端、token 的过期时间等。
4. 如果有必要，可以修改配置文件中的选项，并保存文件。
5. 重启 Keystone 服务，使配置文件生效。

具体而言，可以使用以下命令来重启 Keystone 服务：

systemctl restart openstack-keystone.service

如果重启服务后问题仍然存在，请检查 Keystone 相关服务的日志文件，查看详细的错误信息和发生错误的位置。例如，可以使用以下命令来查看 Keystone 的日志：

tail -f /var/log/keystone/keystone.log

在日志文件中找到错误信息，可以更好地定位和解决问题。

脚本部署Openstack 某企业拟使用OpenStack搭建一个企业云平台，以实现资源池化弹性管理、企业应用集中管理、统一安全认证和授权等管理。 规划： 云服务器1 主机名Controller: 接口eth33IP地址192.168.100.10/24,仅主机模式 接口eth34IP地址保持默认,NAT模式 云服务器2 主机名Compute 接口eth33IP地址192.168.100.20/24,仅主机模式 接口eth34IP地址保持默认,NAT模式 本实验使用到三个网段： 192.168.100.0/24，Openstack管理网络，Vmware仅主机模式 192.168.200.0/24，Openstack数据网络，云主机外部网络，VmwareNAT模式 10.0.0.0/24，云主机内部网络 使用两台主机部署出Openstack平台，要求云平台能够正常创建出云主机并正常通信。

以下是一个简单的脚本部署 OpenStack 的示例，您可以根据自己的实际情况进行修改和调整。本脚本适用于 CentOS 7 系统。
