bitsCN.com 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

#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

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

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

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

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

start slave;

mysql> show slave status/G;
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event
Master_Host: 192.168.1.112
Master_User: slave
Master_Port: 3306
Connect_Retry: 60
Master_Log_File: mysql-test-bin.000022
Read_Master_Log_Pos: 624
Relay_Log_File: mysql-relay-bin.000005
Relay_Log_Pos: 533
Relay_Master_Log_File: mysql-test-bin.000022
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
Replicate_Do_DB: test,blog
Replicate_Ignore_DB:
Replicate_Do_Table:
Replicate_Ignore_Table:
Replicate_Wild_Do_Table:
Replicate_Wild_Ignore_Table:
Last_Errno: 0
Last_Error:
Skip_Counter: 0
Exec_Master_Log_Pos: 624
Relay_Log_Space: 688
Until_Condition: None
Until_Log_File:
Until_Log_Pos: 0
Master_SSL_Allowed: No
Master_SSL_CA_File:
Master_SSL_CA_Path:
Master_SSL_Cert:
Master_SSL_Cipher:
Master_SSL_Key:
Seconds_Behind_Master: 0
Master_SSL_Verify_Server_Cert: No
Last_IO_Errno: 0
Last_IO_Error:
Last_SQL_Errno: 0
Last_SQL_Error:
1 row in set (0.00 sec)

ERROR:
No query specified

最后将master上的表解锁
unlock tables;
