Trying to set up MySQL Replication

I do the following on both servers:
mysql>CREATE USER 'replicator'@'%' IDENTIFIED BY 'some_pass';
mysql>Grant all privileges on *.* to replicator@'%' with grant option;

Open in new window


Then I do the following on the master:
mysqluc> mysqlreplicate --master='replicator'@192.168.92.130:3306 --slave='replicator'@192.168.92.131:3306 --rpl-user replicator:some_pass
WARNING: Using a password on the command line interface can be insecure.
# master on 192.168.92.130: ...
ERROR: Access denied for user 'replicator'@'mysql-1-PC.localdomain' (using password: NO)

Open in new window


I thought 'replicator'@'%' would have access from all hosts?

OK, thanks. Now I did this:
mysqluc> mysqlreplicate --master='replicator:some_pass'@192.168.92.130:3306 --slave='replicator:some_pass'@192.168.92.131:3306 --rpl-user replicator:some_pass
WARNING: Using a password on the command line interface can be insecure.

# Checking for binary logging on master...

ERROR: failed to sync slave with master.

In the logs, I see this:

Seems like replicator@192.168.1.131 gets auto created at the master when mysqlreplicate is executed. It ignores replicator@'%'. This user replicator@192.168.1.131 did not have sufficient access rights. Giving these enabled mysqlreplicate to finish the setup.
