Unable to establish connection to tokens

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

 

问题解决！
