Environment:
PC: ubuntu 10.10 192.168.1.112 (master) 192.168.10.245 (slave)
MySQL : 5.1.49-1ubuntu8.1-log
The database test already exists in master
First modify mysql configuration file: / / etc mysql/my cnf
[master]
#author:zhxia
[slave]
#author:zhxia
Then create the backup account on master
Import the database from master into slave,
Lock the table first, disable write
flush tables with read lock;
Export from master: mysqldump-uroot-p test > /tmp/test.sql
Import to slave: mysql-uroot-p test < /tmp/ test.sql, remember you need to build test first
Go to mysql on master to see the master status

Go to Mysql on slave

Then launch salve and view the status:

Finally, unlock the table on master
unlock tables;
