HomeDatabaseMysql Tutorialmysql数据备份方法总结

本文章来总结mysql数据备份方法,一种是大家常用的利用mysqldump命令方式进行数据备份,另一种是利用dos的xcopy命令带windows计划任务进行自动备份。

利用命令方式xcopy命令,把下面代码保存成bak.bat文件。

 代码如下 复制代码

net stop mysql

xcopy D:/phpStudy/MySQL/data/sql111cn/*.*  D:/db_backup/%date:~0,10%/ /y

net start mysql

然后在你的服务器中做计划任务就可以实现自动备份数据库了,

利用mysqldump命令方式进行数据备份

备份数据库:

在命令提示符窗口(注意不是 MySQL 的 MySQL Command Line Client 窗口)中输入,

 代码如下 复制代码

mysqldump -hlocalhost -uroot -proot        temp  > temp_2011.sql
mysqldump -hlocalhost -u root -proot    temp > temp_2011.sql
mysqldump -h localhost -u root -proot  temp > temp_2011.sql

先进入到 MySQL想要存放备份文件的目录下(便于存放生成的*.sql文件).

恢复数据库:

删除原有数据库,建立数据库,把备份数据库导入。

 代码如下 复制代码

mysqladmin -uroot -p123456 drop database_name

mysqladmin -uroot -p123456 create database_name

mysql -uroot -p123456 database_name

上面可以做一个.php文件,然后利用计划任务进行定时执行就可以备份了。

常用的mysql备份数据命令语句分享

备份MySQL数据库的命令

 代码如下 复制代码
mysqldump -hhostname -uusername -ppassword databasename > backupfile.sql

备份MySQL数据库为带删除表的格式
备份MySQL数据库为带删除表的格式,能够让该备份覆盖已有数据库而不需要手动删除原有数据库。

 代码如下 复制代码
mysqldump -–add-drop-table -uusername -ppassword databasename > backupfile.sql

直接将MySQL数据库压缩备份

 代码如下 复制代码
mysqldump -hhostname -uusername -ppassword databasename | gzip > backupfile.sql.gz

备份MySQL数据库某个(些)表

 代码如下 复制代码
mysqldump -hhostname -uusername -ppassword databasename specific_table1 specific_table2 > backupfile.sql

同时备份多个MySQL数据库

 代码如下 复制代码
mysqldump -hhostname -uusername -ppassword –databases databasename1 databasename2 databasename3 > multibackupfile.sql

仅仅备份数据库结构

 代码如下 复制代码
mysqldump –no-data –databases databasename1 databasename2 databasename3 > structurebackupfile.sql

备份服务器上所有数据库

 代码如下 复制代码
mysqldump –all-databases > allbackupfile.sql

还原MySQL数据库的命令

 代码如下 复制代码
mysql -hhostname -uusername -ppassword databasename

还原压缩的MySQL数据库

 代码如下 复制代码
gunzip

将数据库转移到新服务器

 代码如下 复制代码

mysqldump -uusername -ppassword databasename | mysql –host=*.*.*.* -C databasename

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.
