phpMyAdmin max upload size – Is it preventing database restore?

Oops!! Not able to import your SQL backups via phpMyAdmin?

PhpMyAdmin max upload size determines the size of the database backup that can be restored. Often large backup restores fail due to this limit.

At Bobcares, we often get requests from our customers regarding phpMyAdmin as part of our Server Management Services.

Today, let’s get into the details on how our Support Engineers fix this problem.


What is PHPMyAdmin?

PhpMyAdmin is one of the most widely used MySQL administration tools which provides a GUI for MySQL database management.

We can import and export databases via phpMyAdmin in a similar way as we dump and restore via the command line. Here, it saves data as database dumps.

However, server owners often impose restrictions on the server regarding file uploads, database access, etc. This in a way is to tighten the security of database servers against hack attempts.

Thus, while dealing with phpMyAdmin, users may encounter some problems with importing large backups.

Today, let’s see how our Engineers simplifies such a situation within a few minutes.


How do we fix?

Recently, one of our customers reported errors while trying to import a backup file via phpMyAdmin.

Here, our Engineers checked in detail and found that he was trying to restore a 46 MB file. But, the allowed limit for him was only 2 MB (2048KB) as given in the screenshot.

So, we increased the limit to 50 MB. For that, we modified the PHP configuration file used by PHPMyAdmin.

Firstly, we opened the file /etc/phpX/apache2/php.ini.

vi /etc/phpX/apache2/php.ini

Then, we searched for  upload_max_filesize and changed the value to 50 MB as per the customer request.

At last, we restarted the Apache service using the command below:

service apache2 restart

That fixed the problem and the customer could import the file successfully.


Restore via command line

For websites hosted on Shared servers, modifying the server-wide PHP limits may not be a feasible solution. Therefore, our Dedicated Engineers suggest the customers upload the database to their home directory.

We then use the commands below for taking the dump of the database and restoring it via the command-line.

For backing up a MySQL database, as the root user, we run:

mysqldump -u (username) -p (name of database) > (file name).sql

And, for importing the backup we use the syntax below:

mysql -u (username) -p (name of database) < (filename).sql
