環(huán)境：
PC：ubuntu 10.10 192.168.1.112（master） 192.168.10.245（slave）
MySQL : 5.1.49-1ubuntu8.1-log
在master中已經(jīng)存在數(shù)據(jù)庫test
首先修改mysql配置文件：/etc/mysql/my.cnf
[master]
#author:zhxia

復(fù)制代碼代碼如下:

#master 同步設(shè)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

復(fù)制代碼代碼如下:

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

接著在master上創(chuàng)建備份帳號

復(fù)制代碼代碼如下:

grant replication slave,replication client on *.* to 'slave'@'192.168.10.245' identified by '123456';

將master中的數(shù)據(jù)庫導(dǎo)入到slave中，
先鎖表，禁止寫入操作
flush tables with read lock;
先從master導(dǎo)出：mysqldump -uroot -p test > /tmp/test.sql
再導(dǎo)入到slave： mysql -uroot -p test < /tmp/test.sql ,記得需要先建庫test
進入master上的mysql,查看master狀態(tài)

復(fù)制代碼代碼如下:

mysql> show master status;
+-----------------------+----------+--------------+------------------+
| File| Position | Binlog_Do_DB | Binlog_Ignore_DB |
+-----------------------+----------+--------------+------------------+
| mysql-test-bin.000022 |624 |||
+-----------------------+----------+--------------+------------------+
1 row in set (0.02 sec)

進入slave上的Mysql
#author:zhxia

復(fù)制代碼代碼如下:

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;

然后啟動salve，并查看狀態(tài)：

復(fù)制代碼代碼如下:

start slave;

mysql> show slave status/G;
