使用meb企业备份工具，自动实现记录二进制相关信息
此种备份方法需要安装一个软件 meb ，，软件默认安装在 /opt 目录下，安装过程略

备份前在 my.cnf 中增加如下参数 (show variables like 'innodb%' )
innodb_data_home_dir = /data/mysql #指定 datadir路径
innodb_data_file_path = ibdata1:10M:autoextend
innodb_log_group_home_dir = /data/mysql #指定日志路径，一般同datadir路径相同
innodb_log_files_in_group = 2
innodb_log_file_size = 5242880
log-bin = mysql

步骤：

一、建立帐号

mysql> grant replication slave on *.* to slave@'%' identified by '123';
mysql> flush privileges;

二、使用meb去备份Master的数据

# mkdir /backup
# cd /opt/mysql/meb-3.5/
# ./bin/innobackup --user=root --password=123 --ibbackup=/opt/mysql/meb-3.5/bin/ibbackup --socket=/data/mysqld.sock /etc/my.cnf /backup --slave-info
