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

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
