automysqlbackup-2.5.1-01.sh  最新版 点这里下载

使用说明：

1. 修改文件里的配置部分包括访问mysql的用户名密码，要备份的数据库，备份地址，发送邮件的地址（默认使用postfix）：

[cce]
    # Username to access the MySQL server e.g. dbuser
	USERNAME=debian

	# Password to access the MySQL server e.g. password
	PASSWORD=

	# Host name (or IP address) of MySQL server e.g localhost
	DBHOST=localhost

	# List of DBNAMES for Daily/Weekly Backup e.g. "DB1 DB2 DB3"
	DBNAMES="all"

	# Backup directory location e.g /backups
	BACKUPDIR="/srv/backup/db"

	# Mail setup
	# What would you like to be mailed to you?
	# - log   : send only log file
	# - files : send log file and sql files as attachments (see docs)
	# - stdout : will simply output the log to the screen if run manually.
	# - quiet : Only send logs if an error occurs to the MAILADDR.
	MAILCONTENT="log"

	# Set the maximum allowed email size in k. (4000 = approx 5MB email [see docs])
	MAXATTSIZE="4000"

	# Email Address to send mail to? (user@domain.com)
	MAILADDR="maintenance@example.com"
[/cce]

也可以把上面的东西写到一个配置文件里：

[cce]CONFIGFILE="/etc/automysqlbackup/automysqlbackup.conf"[/cce]

2. 给脚本增加可执行权限

[cce]chmod +x /root/automysqlbackup-2.5.1-01.sh[/cce]

3.用crontab定一个任务：比如每周一的零点备份

[cce]
crontab e

#输入下面的任务：
#格式为dom=day of month
#m h  dom mon dow   command

0 0 * * 1 /var/www/sqlback/automysqlbackup.sh
[/cce]

4.安装postfix,备份日志会自动发送到上面指定的邮箱

[cce]
# for redhat
yum install postfix

# for ubuntu
apt-get install postfix
[/cce]

大功告成，该脚本会在备份文件夹里自动建立monthly，weekly，daily的文件夹
