Replication: Configuring and Checking the Master

You can now check the MySQL’s data directory if the binary log is created. You should find a file something like mysql-bin.000001. You will also find a file mysql-bin.index.

In the mysql-bin.index file you will find the list of all the binary logs. i.e. If you restart the server a multiple times you will find your mysql-bin.index to have something like

./mysql-bin.000001
./mysql-bin.000002
./mysql-bin.000003


Now try this query in the mysql prompt show master logs; It should show something like this, depending the no. of binary logs present.

mysql> show master logs;
+------------------+-----------+
| Log_name         | File_size |
+------------------+-----------+
| mysql-bin.000004 | 9066115   |
| mysql-bin.000005 | 117       |
| mysql-bin.000006 | 98        |
+------------------+-----------+

Now it is essential to add a user account which the replication will use, Since we are granting a permission, you need to log in with a root access to mysql, and then run the following command.

mysql> GRANT REPLICATION SLAVE ON *.*
    -> TO 'repl'@'192.168%' IDENTIFIED BY 'slavepass';

Flush the privileges using mysql> flush privileges

This should ideally make your master ready for Replication.
