Error in phpMyAdmin after updating to v4.8.0: The $cfg['TempDir'] (./tmp/) is not accessible

Question

phpMyAdmin worked fine with v4.7.9. Now after updating to v4.8.0 today (replacing the old phpmyadmin folder against the new one) I\'m getting this mess

Answer 1

1) create the tmp folder

mkdir /usr/share/phpmyadmin/tmp

2) findout your php user

<?php echo `whoami`; ?>

3) Change ownership of the tmp folder to the php user found in step 2

sudo chown -R step2phpuser:step2phpuser /usr/share/phpmyadmin/tmp

4) Signout of phpmyadmin and sign back in

Answer 2

I had the same error message. I'm using Ubuntu16.04 with lampp. You should go to 'phpmyadmin' directory, in my case '/opt/lampp/phpmyadmin/', create a new 'tmp' folder. Open a terminal window and:

cd YOUR_PATH_TO_PHPMYADMIN
sudo mkdir tmp

Now you have to change the group of the 'tmp' folder to give access to php user. In order to find it, you can create a php file inside your localhost directory, in my case 'htdocs'

sudo touch user.php
sudo nano user.php

Inside nano editor, type:

<?php echo `whoami`; ?>

Then press CTRL + O and CTRL + X to save and exit. Open the browser and type in your address bar

localhost/user.php

It shows your php user.

After that, go to the terminal and navigate to your recently created 'tmp' directory inside phpmyadmin directory and type:

sudo chgrp YOUR_PHP_USER tmp -R

And change the permission to the 'tmp' directory:

sudo chmod 775 tmp -R

I recommend never give 777 permission to any file.

I hope it helps!

Solution was to create a folder called tmp like this: /usr/share/phpmyadmin/tmp.

Also make sure that the user (or group) running the webserver (e.g. Apache) has write access to the newly created tmp folder. Consequently, change the ownership to that user or add write access for all users. The latter one might not be really advisable.

I had the same problem but none of the answers above could solve. In my case my php security settings was so strict protecting php to access directories out of scope defined in open_basedir located at my /etc/php.d/99-security.ini(which I added perviously from a security toturial and the settings also could be located at /etc/php.ini file in your case):

;; Limit PHP Access To File System
; Limits the PHP process from accessing files outside
; of specifically designated directories such as /var/www/html/
open_basedir="/home/:/etc/phpMyAdmin/:/var/lib/phpMyAdmin/"

change to:

open_basedir="/home/:/etc/phpMyAdmin/:/var/lib/phpMyAdmin/:'/usr/share/phpmyadmin/tmp/"  ;<== changing to this solved the prblem

you just need to add your own directory in error mesage ('/usr/share/phpmyadmin/tmp/') and the end of open_basedir option. Don't forget placing separator : before adding it.

Answer 5

In my case I added

$cfg['TempDir'] = '/usr/share/phpmyadmin/temp';

to the

config.inc.php File within the phpmyadmin folder

Hope it will help someone

Answer 6

For Arch and Manjaro users:

Create a folder tmp at /etc/webapps/phpmyadmin/ - mkdir /etc/webapps/phpmyadmin/tmp

Set permission to 777 - chmod 777 /etc/webapps/phpmyadmin/tmp

Add this line to the config file at /etc/webapps/phpmyadmin/config.inc.php - $cfg['TempDir'] = '/tmp';

Cheers :)
