Can you follow this document https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_Ranger_Install_Guide/content/configuring... Also if you can provide a screenshot or log file, it will be helpful.

pfa logs rangeradmin-install-logs.txt

I am following below link as per my HDP version https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.0/bk_Ranger_Install_Guide/content/ch_overview...

My ambari server and Rangeradmin are on different nodes

Rangeradmin and its mysql metastore are on same node

I am able to run python dba_script successfully on rangeradmin nodes specifying host as localhost

i am also able to run following command successfully from ambari server node , suggesting there is no firewall issue

nc ambaridbhostname 3306

Yes that is correct

as logs says permission denied so you need yo go to the db that you configured in ranger and grant the provilleges to root user for ranger admin host with grant options and then try again it will work something like:

grant all on Databases to 'root'@'hostname' identified by 'password' with grant option;

Flush privileges;

no this is not working

problem is that i am not able to remote connect my mysql instance

these are azure VMs
