How To Increase Import Size Limit of phpMyAdmin on a CentOS 7 Server

phpMyAdmin Increase Import Size Limit

Many times when we’re migrating our hosting providers or platforms, we occur problems to import the database in the new host’s database. This is because of the import size limit that is imposed by default. This can be limited to 10 MB, 20 MB or sometimes even 2 MB. Mostly in VPS or Linux servers.

In this article, we’re going to learn how to increase the import size limit of phpMyAdmin on a CentOS 7 machine. So let’s begin.

How To Install phpMyAdmin on CentOS 7?

Now if you don’t know how to install phpMyAdmin on a CentOS 7 server, refer to this article on how to install phpMyAdmin on a fresh CentOS 7 machine. So let’s begin increasing the upload limit.

Increase Import Size Limit of phpMyAdmin

The limit is imposed by PHP settings on your server which means it has nothing to do with phpMyAdmin configurations. To increase the limit, we have to edit the PHP configuration which lies in “php.ini”. Whatever we do, we should do it precautiously because doing anything wrong can result in getting the whole PHP broken.

Editing PHP.ini

To edit PHP.ini, we need to find where actually it exists. Generally, people use Apache so we’d consider Apache in this article. The “php.ini” is located inside /etc directory. So we’d use the nano text editor to edit the file. Use the below-mentioned command to find the php.ini file properly.

nano /etc/php.ini

Now there would be a bunch of codes you’d see on your screen. Scroll down by pressing down arrow button till you find any one of these three lines because we’ve to edit them.


Since we’re upgrading the limit, we’d keep it at a moderate level of 128 MB. So to do so, replace old values of above-mentioned defines and put it as desired(recommended 128 MB unless you’re trying to upload big files).

memory_limit = 128M

post_max_size = 128M

upload_max_filesize = 122M

Once done, press CTRL + X and then press Y and then Enter button to save the changes we’ve made. To make them work in effect, we need to restart Apache. To do so, use the following command.

service httpd restart

We’re done! You can now see the limits are increased to what we’ve set(128 MB for this article). From…

2 MB limit - Old

If you still see the limit, try restarting your system. To restart immediately, use the following command.

shutdown -r now

This will restart the server as we’ve mentioned “-r” parameter which means “restart” and “now” means immediately.
