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:

    /*///////////////////////// <br>#FileName: mysql_backup.php <br>#Author: faisun <br>#Website: <font color="#000000">http://www.softpure.com</font> <br>////////////////////////*/    
<p>//保存目录,路径要用反斜杠.您需要手动建立它. <br>$store_folder = 'D:\databse_backup'; </p><p>//用户名和密码 <br>//该帐号须有操作[所有]的数据库及FILE的权限 <br>//否则有些数据库不能备份. <br>$db_username = "root"; <br>$db_password = ""; </p><p>$time=time(); </p><p>$nowdir = "$store_folder\\".date("Ymd",$time).""; <br>if(file_exists("$nowdir.rar")) die("File exists.\n"); <br>@mkdir($nowdir); </p><p>mysql_connect("localhost","$db_username","$db_password"); <br>$query=mysql_list_dbs(); </p><p>while($result=mysql_fetch_array($query)){ <br>system (dirname(__FILE__).'\..\mysql\bin\mysqldump --opt '."$result[Database] -u{$db_username} ".($db_password?"-p{$db_password}":"")." > $nowdir\\$result[Database].sql"); <br>echo "dumping database `$result[Database]`...\n"; <br>} <br>echo "\nWinrar loading...\n"; </p><p>system( dirname(__FILE__)."<font color="#000000">\\WinRAR\\WinRAR.exe</font> a -ep1 -r -o+ -m5 -df \"$nowdir.rar\" \"$nowdir\" " ); </p><p>//删除 5 天前的文件 <br>@unlink("$store_folder\\".date("Ymd",$time-86400*5).".rar"); </p><p>echo "\nOK!\n"; </p><p>> <br></p>

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.

MySQL BLOB: how to optimize BLOBs requestsMySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AM

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AM

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
