Can anyone help me with this ? I am trying to do replication of Centos 5.6

when I tried

mysqldump -u root–all-databases –single-transaction –master-data=1 > masterdump.sql

It shows

mysqldump: Got error: 1045: Access denied for user ‘root’@'localhost’ (using password: NO) when trying to connect

When I tried

mysqldump -u root -p –all-databases –single-transaction –master-data=1 > masterdump.sql

It shows

mysqldump: Error: Binlogging on server not active

Even, I already added binlogging inside my.cnf file

THanks You so Much

After doing this setup, by default, only Information_schema and test databases are accessible from slave and hence only those two databases are getting replicated onto slave.

How to we provide permission for other databases?

Thanks Man…..

I was wondering if the following scenario would be possible.

Server 1: Database X (master)
Server 2: Database Y (master)

- replicating to -

Server 3: Database X, Database Y (slave)

The databases are independent, each master:slave relationship is still 1:1. However, as the slave server only seems to accept configuration details for one master server I can’t figure out if this is possible.

Does anyone have any experience of this?

Maybe the following is one of the solutions.

So in your my.cnf on either master or slave, change the: server-id = # <- to another number.

Let me know if it works or not.

You can run 2 instances on server 3 to accomplish this.

From a brief read of the page it seems like there is no difference between a my.ini or a my.cnf and the same options can be placed in both including the one I mentioned previously.

I have in my ‘my.cnf’:
innodb_table_locks = 0

http://dev.mysql.com/doc/refman/5.0/en/option-files.html

Also there are loads more fun InnoDB options to play with here:

http://dev.mysql.com/doc/refman/4.1/en/innodb-parameters.html

I used it with two servers : master on linux, slave on windows 2K3

With my.ini, be carreful about the paths. I.e.:
relay-log = “X:/mysql/mysql-relay-bin”

Yes, use slashes like Unix (not backslashes as usual with windows) ans put your path under quotes.

one of the superior features of InnoDB is that it can do row level locking rather than the table level.
