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.

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.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

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.

MinGW - Minimalist GNU for Windows
This project is in the process of being migrated to osdn.net/projects/mingw, you can continue to follow us there. MinGW: A native Windows port of the GNU Compiler Collection (GCC), freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All MinGW software can run on 64-bit Windows platforms.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
