怎样进行MYSQL主从复制的搭建

log-bin=mysql-bin

# binary logging format - mixed recommended

binlog_format=mixed         //主从复制模式,混合模式（MBR）默认的

binlog_cache_size=4M      //设置binlog缓存大小

max_binlog_size=300M    //设置binlog文件最大体积

replicate_do_db=retail

mysql> GRANT REPLICATION SLAVE ON *.* TO 'server01'@'%' IDENTIFIED BY 'server01';

mysql>FLUSH TABLES WITH READ LOCK;   //先锁定数据库，等恢复完成后，再解锁

Query OK, 0 rows affected (0.00 sec)

mysql> reset master;

Query OK, 0 rows affected (0.00 sec)

不要退出这个终端，否则这个锁就失效了；在不退出终端的情况，再开一个终端直接打包压缩数据文件或使用mysqldump工具来导出数据。

# mysqldump -uroot -p  retail > /tmp/retail.sql

mysql> show master status;       //查看主服务器binlog和Postion

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

File: mysql-bin.000001

Position: 2424

Binlog_Do_DB:

Binlog_Ignore_DB:

1 row in set (0.00 sec)

#binlog_format=mixed

# required unique id between 1 and 2^32 - 1

# defaults to 1 if master-host is not set

# but will not function as a master if omitted

server-id= 3       //跟master区分开来

read_only=1

replicate_do_db= retail

创建retail数据

mysql> create database retail

进行数据的导入

mysql>  SOURCE /tmp/retail.sql

mysql> CHANGE MASTER TO MASTER_HOST='192.168.47.149',MASTER_USER='server',MASTER_PASSWORD='server', MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=2424;

mysql> SLAVE START   //启动SLAVE服务

mysql> SHOW SLAVE STATUS\G;  //检查slave的连接情况

mysql> SHOW SLAVE STATUS\G
