Ranger Admin install fails with Access Denied error

[#1]

I am seeing the following when it is trying to install Ranger Admin on the Ranger host server:

2016-01-27 08:48:59,962  [I] Database ranger already exists.
2016-01-27 08:48:59,962  [I] ---------- Granting permission to Ranger Admin db user ----------
2016-01-27 08:48:59,962  [I] ---------- Granting privileges TO user 'rangeradmin'@'%' on db 'ranger'----------
SQLException : SQL state: 42000 com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user 'root'@'hostname' to database 'ranger' ErrorCode: 1044
SQLException : SQL state: 42000 com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user 'root'@'hostname' to database 'ranger' ErrorCode: 1044
2016-01-27 08:49:00,520  [E] Granting privileges to 'rangeradmin' failed on 'ranger'

I have logged onto MySQL on the host machine and granted the following privileges and still the installation throws Access Denied error.

What privileges did you grant? I think there is something missing in your post

[#3]

Something like this:

GRANT ALL ON mydb.*TO'myuser'@'%';

[#4]

Try this:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'hostname' WITH GRANT OPTION;

[#5]

@Kay Aries you have MySQL issue not a ranger issue. Please see this Thread

[#6 · Accepted solution]

@Kay Aries

Try this

grant all privileges on *.* to 'root'@'host' identified by 'password' with grant option;

then restart/reinstall rangeradmin process

[#7]

Ranger is in this state now:

Invalid event: HOST_SVCCOMP_OP_IN_PROGRESS at INSTALL_FAILED

I will delete the service through Rest API and will try it again.

Thanks for all the help.

I did a re-install and Neeraj's solution worked for me. Thank you all, guys.

[#9]

Thanks Neeraj...your solution worked

[#10]

It worked for me when used with "identified by 'password' " string in grant all privileges on *.* to 'root'@'oozie-test2' identified by 'password' with grant option;
