This topic we are installing openstack train /queen version in CentOS7 using packstack, but we are getting below error during the installation.


ERROR : 

Failed to run remote script, stdout:

stderr: Warning: Permanently added '192.168.156.200' (ECDSA) to the list of known hosts.

Cases : 

We are getting known hosts issue during the installation and it is  SSH issue, ssh connection denied to access the node  

Solution

To resolve this issue we will add the host ip/network of openstack environment in below file

vi ~/.ssh/config

Add below line in the config file and save it 

Host 192.168.156.*
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null



Enjoy!! try again your openstack installation
