You are right, log-bin is not required on a slave. I have it in my setup with log-slave-updates on for a chained replication where slave works as master as well. > > - check replication account permissions on the master.

Check this one out http://dev.mysql.com/doc/mysql/en/Upgrading-grant-tables.html for priv table upgrade.

Below are settings I have for both slave and master. Maybe you can try them in your setup. default-character-set=utf8 # time zone has to be the same on master and slave for correct replication (from 4.1) default-time-zone=GMT log_warnings log_slow_queries log-bin log-slave-updates slave_compressed_protocol=1 # skip illegal collation error slave-skip-errors=1267 > thanks again. > Frank > Attention: Any views expressed in this message are those of the individual sender, except where the message states otherwise and the sender is authorized to state them to be the views of any such entity.

Turns out when my hosting provider "installed" MySQL 4.1, it was actually an install over a 3.x data directory. The Priv tables were never updated, so I never had the appropriate "REPLICATION SLAVE" Priv, so the thread never started. It never did say why it did not start though. Threads are now running, but data is not getting replicated. Need to figure that out now. thanks again.

- make sure log-bin is enabled on both master and slave (looks like it is not present in the slave config) - check replication account permissions on the master. I don't remember details, but you can find required permissions in the docs on mysql web site, or doc file in mysql installation directory. -Original Message- From: Frank Febbraro [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 18, 2005 9:41 AM To: mysql@lists.mysql.com Subject: Re: Replication Slave I/O Thread won't start on 4.1.8 One thing I left out is that we are running 4.1.8-Max-log not 4.1.8-standard-log Could that have anything to do with it?

Re: Replication Slave I/O Thread won't start on 4.1.8
One thing I left out is that we are running 4.1.8-Max-log not 4.1.8-standard-log Could that have anything to do with it?
