以前要做mysql的备份,我往往都是利用 EMS SQL Manager 实现导出 sql脚本文件,或者导出dbf 文件。而要把本地数据库迁移到远程直接把脚本在服务端执行就OK。
不过最近发现这个可视化操作有点点问题,就是当数据条数超过一定数目EMS SQL Manager就挂了,也不知道是否是软件问题……当然该开始我是将大的数据库文件分拆成小份小份的,多次导入。刚才发现同事用了mysql 自带的mysqldump 工具就不存在这个问题。 (羞愧,不过我平时极少接触数据库)
这里记录下操作方式:
1. 进入bin目录,执行命令:
mysqldump -hlocalhost -uroot -padmin local_db > a.sql
2. 这时发现在bin目录生成了 a.sql 文件,继续命令:
mysql remote_db
下面是同步原理,需要的朋友可以参考下。
1. backup/dump ur local database at 1:00 am and
2. ftp the sql script to the server side with a bash script at 2:00 am
3. load the sql script in the server side at 3:00 am.
不是已经说得很清楚了。。 :)
比置顶的那个问题,你的问题已经很宽松了。
1。先备份本地数据库,unix/linux下用cronjob,windows下用schedule都可以定时在
早上1点时启动备份的bash或bat文件
2。备份数据库要相当的时间,所以定在早上2点,启动另一个bash/bat文件,里面写
上ftp的东东,不超过5行,就可以把刚才备份好的文件传到server上,这也需要一段时间
3。在server上3点时启动第三个bat/bash文件,把上传好的文件加载到数据库里。

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.
