实现 win2003 下 mysql 数据库每天自动备份
1. 环境: windows server 2003 + PHP5 + MySQL 5.1.6.
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:
代码如下:
//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.\r\n");
@mkdir($nowdir);
mysql_connect("localhost","$db_username","$db_password");
$query=mysql_list_dbs();
$command = '';
while($result=mysql_fetch_array($query)){
$command .= dirname(__FILE__).'\..\mysql\bin\mysqldump --opt '."$result[Database] -u{$db_username} ".($db_password?"-p{$db_password}":"")." > $nowdir\\$result[Database].sql \r\n";
$command .= "echo dumping database `$result[Database]`... \r\n";
}
$command .= "echo Winrar loading...\r\n";
$command .= dirname(__FILE__)."\\WinRAR\\WinRAR.exe a -ep1 -r -o+ -m5 -df \"$nowdir.rar\" \"$nowdir\" \r\n";
$command .= "echo OK!\r\n";
$command .= "del mysqldumping_temp.bat\r\n";
$fp = fopen('mysqldumping_temp.bat','w');
fwrite($fp,$command);
fclose($fp);
//删除 5 天前的文件
@unlink("$store_folder\\".date("Ymd",$time-86400*5).".rar");
?>
5. D:/php 下建立文件 mysql_backup.bat,内容为:
echo off
php.exe mysql_backup.php
if exist mysqldumping_temp.bat call mysqldumping_temp.bat
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.
