Master# pwd
/var/eyou/mysql/bin
Master#./mysql –u root –p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2 to server version: 4.1.12

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> GRANT FILE ON *.* TO rep@192.168.0.244 IDENTIFIED BY ‘eyou’;

mysql> GRANT REPLICATION SLAVE ON *.*  TO rep@192.168.0.244 IDENTIFIED BY ‘eyou’;

赋予192.168.10.244也就是Slave 机器有File权限, 这个4.1.12版对replication的权限好像做了调整，只赋予Slave机器有File权限还不行，还要给它REPLICATION SLAVE的权限才可以。

然后打包要复制的数据库

Master# cd var
Master# tar czvf reptest.tar.gz reptest

这样，我们得到一个reptest数据库的打包文件reptest.tar.gz

2设置主服务器Master的my.cnf，启动Mysql服务

Master# vi /etc/my.cnf

在[mysqld]添加或修改以下的

[mysqld]
log-bin                                     #打开logbin选项以能写到slave的 I/O线程;
server-id=1                             #表示是本机的序号为1,一般来讲就是master的意思.
sql-bin-update-same
binlog-do-db= reptest         #表示同步reptest数据库;

然后把Master主服务器的Mysql重启。

Master# /var/eyou/mysql/bin/mysqladmin –u root –p shutdown
Master# /var/eyou/mysql/bin/safe_mysqld --user=mysql &

3、建立Slave数据库
刚才在Master中打包了reptest.tar.gz，它的作用就是要在Slave恢复成一样的数据库。先把Master 的reptest.tar.gz文件传到Slave机器中去。然后

Slave# tar zxvf reptest.tar.gz -C /var/eyou/mysql/var/

4、修改Slave服务器的my.cnf

Slave# vi /etc/my.cnf

在[mysqld]添加或修改以下的

master-host=192.168.10.217
master-user=rep
master-password=eyou
master-port=3306
server-id=2
master-connect-retry=60
replicate-do-db=reptest 　　　[要更新的数据库]
log-slave-updates

5、删除Slave端数据库目录中的master.info

Slave# rm /var/eyou/mysql/var/master.info

6、重启动Slave的slave start。

Slave# /var/eyou/mysql/bin/mysqladmin –u root –p shutdown
Slave# /var/eyou/mysql/bin/safe_mysqld --user=mysql &

7、测试
先检测两个Mysql数据库中的reptest是否正常。
正常情况应该是Master和Slave 中的Mysql 都有相同的reptest 数据库，并且里面的数据都一样。
然后测试replication 功能是否起用。
在Master中的reptest数据库添加一笔数据：

Master# /var/eyou/mysql/bin/mysql –u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 12 to server version: 4.1.12

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> use  reptest;
Database changed
mysql> INSERT INTO rep_table  VALUES ('test1', '4321', 'T',24);
Query OK, 1 row affected (0.00 sec)
mysql>

然后查看Slave机器的reptest数据库：

Slave#/var/eyou/mysql/bin/mysql –u root –p

Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 12 to server version: 4.1.12

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> use  reptest;
Database changed
mysql>select * from reptable;;
