After following this documentation for Installing Heat on ubuntu 20.04 : https://docs.openstack.org/heat/victoria/install/install-ubuntu.html I encountered this error : " ERROR: All heat engines are down. "

  • Where did you encounter it? Did you see it on the command line? If so, which command caused it? Or did you find it in a log file? If yes, which log file? Have you searched the error message on the internet? What did you find? Finally, what do you expect from the Stackoverflow community? You did not ask a question. – berndbausch Mar 26 '21 at 14:41
  • thank you for the quick reply ! i enounterd this error t on the command line when i type this command : openstack orchestration service list what i'm asking for is for the heat to work correctly and for this command to show all the engines and to list hte service components to verify the successful launch and registration of each process – mohamed lahsoumi Mar 27 '21 at 14:54
  • here's a link for what the output of this command should be : https://docs.openstack.org/heat/victoria/install/verify.html – mohamed lahsoumi Mar 27 '21 at 14:55
  • Have you checked the Heat logs? – berndbausch Mar 27 '21 at 16:27
  • where can i find them exactly ? – mohamed lahsoumi Mar 28 '21 at 12:09
  • Most probably under [/var/log/heat](https://docs.openstack.org/heat/victoria/configuration/logs.html), but it depends on how you configured your cloud. – berndbausch Mar 28 '21 at 12:25
  • these are the output of ls /var/log/heat : heat-api-cfn.log heat-api-cfn.log.1 heat-api.log heat-api.log.1 heat-engine.log heat-engine.log.1 – mohamed lahsoumi Mar 28 '21 at 13:00
  • These are the log files, yes. Your mission, should you choose to accept it, is to find messages in these log files that help you understand why the Heat components are not running. – berndbausch Mar 28 '21 at 13:50
  • I accept the mission xD – mohamed lahsoumi Mar 28 '21 at 14:59
  • These are the errors that i found in the log : Unable to validate token: Identity server rejected authorization necessary to fetch token data: keystonemiddleware.auth_token._exceptions.ServiceError: Identity server rejected authorization necessary to fetch token data keystonemiddleware.auth_token [-] Identity response: {"error":{"code":401,"message":"The request you have made requires authentication.","title":"Unauthorized"}} keystoneauth1.exceptions.http.Unauthorized: The request you have made requires authentication. (HTTP 401) (Request-ID: ...) – mohamed lahsoumi Mar 28 '21 at 15:36
  • i found a typing error in the heat.conf file and fixed it now when i run this command as root : openstack orchestration service list the output is : ERROR: None – mohamed lahsoumi Mar 28 '21 at 16:05
