问题
I couldn't find an answer to my question.
I have 2 mysql servers.
- Master server
- Slave server
Now i want to add another Slave server but i have other website running on that server.
Can i replicate just one database?
回答1:
Yes you can
If you want to replicate just one database from master, you can set replicate-do-db in your /etc/my.cnf or set replicate-do-db as mysql argument, for example:
replicate-do-db=db01
If you have multi databases to be replicated, /etc/my.cnf should be like this:
replicate-do-db=db01
replicate-do-db=db02
If you just want slave to ignore some database, you can set replicate-ignore-db:
replicate-ignore-db=db01
More details on MySQL document: http://dev.mysql.com/doc/refman/5.1/en/replication-options-slave.html#option_mysqld_replicate-do-db

Adding these lines to the /etc/my.conf file of the slave machine solved my problem. Thanks.
replicate-do-db=Refill
However, please note that after doing this i had to restart both the databases and update the new file name and position from the master server by typing below command:
mysql> show master status;
Add this information to your MySQL on slave machine and start slave.
