定时备份网站程序和MySQL数据库到FTP

这个是脚本是我自己一直在用的，非常好用，定时把网站程序和网站数据库备份并上传到FTP，备份数据保存7天；当你经历过数据丢失，就知道数据备份的重要性。



参数解释

Backup_Home：设置本机备份文件的路径
MySQL_Dump：MySql mysqldump导出工具路径
Backup_Dir：网站程序路径
Backup_Database：备份网站的数据库名
MYSQL_UserName：数据库账户
MYSQL_PassWord：数据库密码
FTP_Host：ftp地址
FTP_Username：FTP登陆账户
FTP_Password：FTP登陆密码
FTP_Dir：设置备份到ftp的路径

先运行以下命令，免得报错。

CentOS：yum install lftp  或  Debian/Ubuntu：apt-get install lftp

复制以下内容另存为backup.sh 

#!/bin/bash
#server ip : 8.8.8.8
#Funciont: Backup website and mysql database

#IMPORTANT!!!Please Setting the following Values!

Backup_Home="/home/wwwroot/"

以上仅是Linux系统才可以使用。
