Step 1 – Configure the Master Server
First we have to edit /etc/mysql/my.cnf. We have to enable networking for MySQL, and MySQL should listen on all IP addresses, therefore we comment out these lines (if existant):
#skip-networking
#bind-address = 127.0.0.1
Furthermore we have to tell MySQL for which database it should write logs (these logs are used by the slave to see what has changed on the master),
which log file it should use, and we have to specify that this MySQL server is the master. We want to replicate the database exampledb, so
we put the following lines into/etc/mysql/my.cnf:
server-id = 1
log_bin = /var/log/mysql/mysql-bin.log
binlog_do_db = exampledb
Then we restart MySQL:
/etc/init.d/mysql restart
Then we log into the MySQL database as root and create a user with replication privileges:
mysql -u root -p
Enter password:
Now we are on the MySQL shell.
mysql>GRANT REPLICATION SLAVE ON *.* TO ’slave_user’@’%’ IDENTIFIED BY ‘’; (Replace with a real password!)
mysql>FLUSH PRIVILEGES;
Next (still on the MySQL shell) do this:
mysql>USE exampledb;
mysql>FLUSH TABLES WITH READ LOCK;
mysql>SHOW MASTER STATUS;
The last command will show something like this:
+—————+———-+————–+——————+
| File | Position | Binlog_do_db | Binlog_ignore_db |
+—————+———-+————–+——————+
| mysql-bin.006 | 183 | exampledb | |
+—————+———-+————–+——————+
1 row in set (0.00 sec)
Write down this information, we will need it later on the slave!
Then leave the MySQL shell:
mysql>quit;
Step 2 – Configure the Slave Server(Windows XP)
Edit the c:\program files\mysql\mysql server 5.0\my.ini
server-id=2
master-host=db01.yourdomain.net (or IP address)
master-port=3306
master-user=slave_user
master-password=password
master-port=3306
master-user=slave_user
master-password=password
Step 3 – Restart Mysql Service
goto> Control Panel>Administrative Tools>Services>Mysql
Restart Service
mysql > Stop slave;
mysql>CHANGE MASTER TO MASTER_HOST=’192.168.10.175′, MASTER_USER=’slave_user’, MASTER_PASSWORD=’password’,MASTER_LOG_FILE=’mysql-bin.000008′,MASTER_LOG_POS=98;
mysql > Start slave;
