ERROR: Unable to establish connection to http://controller:35357/v3/auth/tokens
[[email protected] ~]# openstack server list

Unable to establish connection to

http://controller:35357/v3/auth/tokens

二、解決方法

1.檢查兩個節點修改的配置檔案是否有誤。
2.重啟httpd、memcached服務

Controller節點

注：由the identity service failed可知可能是認證服務有問題

# systemctl restart httpd.service
# systemctl restart memcached.service

3.重啟兩個節點相應的cinder服務

Controller節點

# systemctl restart openstack-cinder-scheduler.service openstack-cinder-api.service
 

Compute節點

# systemctl restart openstack-cinder-volume.service target.service
