环境：
PC：ubuntu 10.10 192.168.1.112（master） 192.168.10.245（slave）
MySQL : 5.1.49-1ubuntu8.1-log
在master中已经存在数据库test
首先修改mysql配置文件：/etc/mysql/my.cnf
[master]
#author:zhxia
代码如下:
#master 同步设置
server-id = 1
log_bin = /var/log/mysql/mysql-test-bin.log
expire_logs_days = 10
max_binlog_size = 100M
binlog_format =mixed
[slave]
#author:zhxia
代码如下:
server-id = 2
replicate-do-db=test
replicate-do-db=blog
log_bin = /var/log/mysql/mysql-bin.log
relay_log =/var/log/mysql/mysql-relay-bin.log
expire_logs_days = 10
max_binlog_size = 100M
#binlog_do_db = test
#binlog_ignore_db = include_database_name
binlog_format = mixed
slave-net-timeout=6012 master-connect-retry=10
接着在master上创建备份帐号
代码如下:
grant replication slave,replication client on *.* to 'slave'@'192.168.10.245' identified by '123456';
将master中的数据库 导入到slave中，
先锁表，禁止写入操作
flush tables with read lock;
先从master导出：mysqldump -uroot -p test > /tmp/test.sql
再导入到slave： mysql -uroot -p test < /tmp/test.sql ,记得需要先建库test
进入master上的mysql,查看master状态
#author:zhxia
代码如下:
mysql> show master status;
+-----------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+-----------------------+----------+--------------+------------------+
| mysql-test-bin.000022 | 624 | | |
+-----------------------+----------+--------------+------------------+
1 row in set (0.02 sec)
进入slave上的Mysql
#author:zhxia
代码如下:
change master to master_host='192.168.1.112', master_user='slave', master_password='123456', master_log_file='mysql-test-bin.000022', master_log_pos=106;
然后启动salve，并查看状态：
#author:zhxia
代码如下:
start slave;
mysql> show slave status\G;
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event

Relay_Log_Pos: 533

Replicate_Do_DB: test,blog
Replicate_Ignore_DB:

Last_Errno: 0

Last_IO_Errno: 0
Last_IO_Error:

最后将master上的表解锁
unlock tables;
