Unable to upload database with phpMyAdmin: Script timeout passed or 504 Gateway Timeout is shown

Symptoms

When trying to upload a database in phpMyAdmin more than 500Mb, getting the error.

PLESK_ERROR: Script timeout passed, if you want to finish import, please resubmit same file and import will resume.

Or:

CONFIG_TEXT: ERROR: Maximum execution time of 300 seconds exceeded (DBIMysqli.php:262)

Cause

The error occurs because of a huge file and the restoration process fails with timeout.

If it does not help, follow one of the solutions below.

Solution 1

Increase the 'ExecTimeLimit'  value:

Linux:

1. Login to the server over SSH.

2. Create the file config.inc.php at /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/ copying the content of config.default.php file:

   # cp -p /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.default.php /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.inc.php

3. Increase the value of $cfg['ExecTimeLimit'] in /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.inc.php:

   CONFIG_TEXT: $cfg['ExecTimeLimit'] = 3600;

4. Increase the settings in /etc/sw-cp-server/config to avoid '504 Gateway Timeout' error:

   CONFIG_TEXT: fastcgi_read_timeout 3600;
   fastcgi_send_timeout 3600;

5. Restart sw-cp-server:

   # service sw-cp-server restart

Note: if the issue still persist, the browser cache sholud be cleared.

Windows:

1. Login to the server over RDP.

2. Create the file config.inc.php at %plesk_dir%admin\htdocs\domains\databases\phpMyAdmin\libraries\.

3. Copy the content of %plesk_dir%admin\htdocs\domains\databases\phpMyAdmin\libraries\config.default.php to %plesk_dir%admin\htdocs\domains\databases\phpMyAdmin\libraries\config.inc.php.

4. Increase the value of $cfg['ExecTimeLimit'] in %plesk_dir%admin\htdocs\domains\databases\phpMyAdmin\libraries\config.inc.php:

   CONFIG_TEXT: $cfg['ExecTimeLimit'] = 3600;

Solution 2

Upload the database via command prompt:

1. Login to the server over RDP.
2. Upload the database dump to the server.
3. Restore the database:
