四.在master机上为slave机添加一同步帐号
mysql> grant replication slave on *.* to 'admin'@'172.29.141.115' identified by '12345678';
mysql> flush privileges ;
五.配置slave的my.cnf,添加以下内容
注意:
1.如果mysql是5.5.3-m3 的版本，只需
在[mysqld]字段下添加如下内容
server-id=2
2.如果是5.0x的版本，需要
在[mysqld]字段下添加如下内容
server-id=2
log-bin=mysql-bin //这是同步的binlog，具体以你的binlog为准
master-host=172.29.141.112
master-user=admin
master-password=12345678
master-port=3306
master-connect-retry=60 //如果发现主服务器断线，重新连接的时间差；
replicate-do-db=blog //同步的数据库，不写本行 表示 同步所有数据库
replicate-ignore-db=mysql //不需要备份的数据库
log-slave-update
slave-skip-errors
我的mysql是5.5.3，这里给出我的slave my.cnf配置文件
