Linux下MySQL數據庫的主從同步復制配置

[root@localhost ~]mysql -uroot -p

mysql>grant replication slave on *.* to 'testuser'@'192.168.1.102' identified by '12345678';
mysql>flush privileges #刷新權限

server-id=1 
log-bin=mysql-bin #啟動MySQL二進制日志系統，
binlog-do-db=ourneeddb #需要同步的數據庫
binlog-ignore-db=mysql #不同步mysql系統數據庫，若還有其它不想同步的，繼續添加
[root@localhost ~]/etc/init.d/mysqld restart #重啟服務
