  终于让服务器每天早上备份一次 MySQL 数据库并自动打包,同时删除 5 天前的备份文件. 分享如下.

  1. 环境: windows server 2003 + Apache 2.0 + PHP5 + MySQL 4.0.26 .

  2. 假设 PHP 安装目录为 D:/php ,MySQL 安装目录为 D:/mysql.

  3. 在 D:/php 下建立目录 WinRAR, 把你 winrar 安装目录下的 WinRAR.exe 和 RARReg.KEY 复制到 D:/php/WinRAR .

  4. D:/php 下建立文件 mysql_backup.php:

  /*/////////////////////////
#FileName: mysql_backup.php
#Author: faisun
#Website: http://www.softpure.com
////////////////////////*/  
//保存目录,路径要用反斜杠.您需要手动建立它.
$store_folder = 'D:databse_backup';
//用户名和密码
//该帐号须有操作[所有]的数据库及FILE的权限
//否则有些数据库不能备份.
$db_username = "root";
$db_password = "";
$time=time();
$nowdir = "$store_folder/".date("Ymd",$time)."";
if(file_exists("$nowdir.rar")) die("File exists.
");
@mkdir($nowdir);
mysql_connect("localhost","$db_username","$db_password");
$query=mysql_list_dbs();
while($result=mysql_fetch_array($query)){
system (dirname(__FILE__).'..mysqlinmysqldump --opt '."$result[Database] -u{$db_username} ".($db_password?"-p{$db_password}":"")." > $nowdir/$result[Database].sql");
echo "dumping database `$result[Database]`...
";
}
echo "
Winrar loading...
";
system( dirname(__FILE__)."/WinRAR/WinRAR.exe a -ep1 -r -o+ -m5 -df "$nowdir.rar" "$nowdir" " );
//删除 5 天前的文件
@unlink("$store_folder/".date("Ymd",$time-86400*5).".rar");
echo "
OK!
";
>
  5. D:/php 下建立文件 mysql_backup.bat,内容只有一句:

 php.exe mysql_backup.php

  6. 双击该 bat 文件运行,如果能备份了,OK,下一步添加任务计划.

  7. 把 D:/php/mysql_backup 添加到任务计划,时间选每天. 根据服务器的监测结果,每天早上 5-8 时为流量低峰期. 由于 5-7 时有些数据库的清理工作,我把时间定在了早上 8 点整.
