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！
