MySQL Master Slave同步配置

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

1 #master 同步设置

2 server-id = 1

3 log_bin = /var/log/mysql/mysql-test-bin.log

4
expire_logs_days = 10

5 max_binlog_size = 100M

6 binlog_format =mixed

[slave]

#author:zhxia

1 server-id = 2

2 replicate-do-db=test

3 replicate-do-db=blog

4 log_bin = /var/log/mysql/mysql-bin.log

5 relay_log =/var/log/mysql/mysql-relay-bin.log

6 expire_logs_days = 10

7 max_binlog_size = 100M

8 #binlog_do_db = test

9 #binlog_ignore_db = include_database_name

10 binlog_format = mixed

11 slave-net-timeout=60

12 master-connect-retry=10

接着在master上创建备份帐号

1 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

1 mysql> show master status;

2 +-----------------------+----------+--------------+------------------+

3 | File | Position | Binlog_Do_DB | Binlog_Ignore_DB |

4 +-----------------------+----------+--------------+------------------+

5 | mysql-test-bin.000022 | 624 | | |

6 +-----------------------+----------+--------------+------------------+

7 1 row in set (0.02 sec)

进入slave上的Mysql

#author:zhxia

1 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

1 start slave;

2

3 mysql> show slave status\G;

4 *************************** 1. row ***************************

最后将master上的表解锁

unlock tables;
