所采用的mysql数据库是rpm包方式安装

1. Master:修改/etc/my.cnf文件[mysqld]

[mysqld]

server-id = 1

log-bin

innodb_flush_log_at_trx_commit=1

sync_binlog=1

datadir=/var/lib/mysql

2. Slave:修改/etc/my.cnf文件[mysqld]

[mysqld]

server-id=2

datadir=/var/lib/mysql

3. Master:在master数据库设置用来同步的slave用户权限

GRANT REPLICATION SLAVE ON *.*

TO ''@''

IDENTIFIED BY '';

例: grant replication slave on *.* to 'repl'@'192.168.1.2' identified by '123456';

4.Master上锁表：flush tables with read lock；

解锁：unlock tables；

5. Master数据导到slave

打包/var/lib/mysql目录，然后scp拷贝到从库上，覆盖从库/var/lib/mysql目录

6. Master查看日志节点和Position信息

查看主库信息获得日志文件以及position

mysql> show master status;

+------------------+------------+--------------+------------------+

| File             | Position   | Binlog_Do_DB | Binlog_Ignore_DB |

+------------------+------------+--------------+------------------+

| mysql-bin.000596 | 1050931156 |              |                  |

+------------------+------------+--------------+------------------+

7.从库同步

mysql>STOP SLAVE；

mysql>CHANGE MASTER TO

>MASTER_HOST='',

>MASTER_USER='',

>MASTER_PASSWORD='',

>MASTER_LOG_FILE='',

>MASTER_LOG_POS=;

mysql>START SLAVE;

执行完上述命令后

mysql> show slave status \G
