在控制节点上安装完Nova组件后，通过systemctl批量启动服务时遇到'No such file or directory'错误。发现nova-consoleauth从18.0.0版本后已被弃用。解决方法是分别启用其他服务，如openstack-nova-api, openstack-nova-scheduler, openstack-nova-conductor, openstack-nova-novncproxy。" 111143479,10289978,ROS通讯问题与解决方案,"['机器人操作系统', 'ROS网络', 'Linux', 'CMake']

在控制节点上安装nova组件后启动时遇到的问题

在控制节点上安装nova组件完成后，以如下方式启动时：

[root@controller ~]# systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstaci-nova-novncproxy.service
Failed to execute operation: No such file or directory

于是我把它每个单独启动：

[root@controller ~]# systemctl enable openstack-nova-api.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-api.service to /usr/lib/systemd/system/openstack-nova-api.service.
[root@controller ~]# systemctl enable openstack-nova-consoleauth.service
Failed to execute operation: No such file or directory
[root@controller ~]# systemctl enable openstack-nova-scheduler.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service to /usr/lib/systemd/system/openstack-nova-scheduler.service.
[root@controller ~]# systemctl enable openstack-nova-conductor.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service to /usr/lib/systemd/system/openstack-nova-conductor.service.
[root@controller ~]# systemctl enable openstack-nova-novncproxy.service
Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service to /usr/lib/systemd/system/openstack-nova-novncproxy.service.

经过在网上查询得知，nova-consoleauth从18.0.0版后就被弃用了。因此，想要启动nova服务只需要
[root@controller ~]# systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
就可以了。
