空 SQL 文件 - PHPmyAdmin

Question

So I'm trying to export my e-commerce database via PhpMyAdmin and it keeps downloading empty SQL Files. I'm 100% sure i'm selecting all my tables and I'm using the default sets when opening the export tab. It keeps coming out to 0 bytes. If needed i'll detail all the checkboxes I have checked in php my admin but not sure if it's needed.

Is my database too big? What's another way I can back up my database?

Answer 1

您可以在终端上使用mysqldump 。

Answer 2

Might be timeout or memory limit exceeded. Try mySQLDumper . Works fine for me.

Answer 3

I had the same issue as OP - the exported .sql backup was always empty. Selecting the gzipped compression did the trick - hope this helps somebody else!

Answer 4

Using mysqldump through ssh worked for me

Example

user: admin password: pass123 database name: mydatabase

mysqldump --add-drop-database --add-drop-table --user=admin --password=pass123 mydatabase > backup.sql

Then I downloaded the file via FTP

Answer 5

这可能是内存问题，暂时将 php.ini 文件中的 memory_limit 增加到 512M（假设它目前少得多），重新启动所需的服务以使此更改生效，我敢打赌这现在对您有用...不要忘记在完成后将 memory_limit 改回。
