需要的依赖库
Config::IniFiles
MIME::Lite
DBD::mysql
DBI
Sys::Syslog
建议使用CPAN安装,多快好省

首先获得全局读锁,接着将缓存中数据写到磁盘,然后执行LVM快照,最后解锁、以下是我采集的一个主要过程

20131105 13:53:34 Info: Running: lvremove -f /dev/vg/mysql_snapshot

整个过程执行完后,只留下backup-20131105_135117_mysql.tar.gz,该tar包里面含二进制日志坐标、my.cnf及mysql所有文件

该工具也有邮件告警的功能,以下是我的配置文件邮件告警部分
# cat /etc/mylvmbackup.conf | grep mail
mail_report_on=always
mail_from=root@localhost
mail_to=645522734@qq.com
mail_subject=mylvmbackup report for localhost
注释
--mail_report_on:取值{never,always,errors},其中never为默认值,always表示总是发邮件,errors只在出错时发
