Unable to establish connection to tokens

时间:2023-11-10 18:07:20

安装openstack后遇到的第一个问题。

执行命令nova list得到如下结果:

[root@localhost ~(keystone_admin)]# nova list
No handlers could be found for logger "keystoneauth.identity.generic.base"
ERROR (ConnectFailure): Unable to establish connection to http://10.20.0.14:5000/v2.0/tokens
猜测可能是keystone没有开启
查看service的状况

红色部分确定是keyston没有启动。
运行命令启动
启动keystone:
systemctl start openstack-keystone
