/usr/bin为mysql安装目录
建备份文件夹：
mkdir mysql_data_bak
建脚本文件：
touch autobackupmysql.sh

vi autobackupmysql.sh
在脚本中加入如下内容：
filename=`date +%Y%m%d`
/usr/bin/mysqldump -opt mysql -u root -proot|gzip >/mysql_data_bak/name$filename.gz
这里注意了
一般的：
**********************************************************
打开自动执行文件
vi /etc/crontab
在etc中加入如下内容，让其自动执行任务。
01 15 * * * root /mysql_data_bak/autobackupmysql
**********************************************************
Redhat方法：
　　Redhat的crontab采用按时间调用4个目录（/etc/cron.hourly：每小时；/etc/cron.daily：每
天；/etc/cron.weekly：每周；/etc/cron.monthly：每月）中脚本出来运行的方式。
　　Redhat中只需要将刚才编辑的脚本复制到相应的目录即可。
cp /mysql_data_bak/autobackupmysql etc/cron.daily
重启etc
/etc/rc.d/init.d/crond restart
