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

well,in my case this error has occured when i was using ubuntu 18.04. All you need is to go to the installation directory (in ubuntu - opt/lampp/phpmyadmin) and create a folder tmp with all the suitable read/write permissions.

Follow these steps in case of ubuntu-

1.go to the PMA installation directory by typing following commands in cmd-

cd opt/lampp/phpmyadmin

2.Then type the following command-

sudo mkdir tmp && chmod 777 tmp

and then you are done..!! I hope it helps..

Answer 2

Create a temp directory owned by and restricted to the webserver user. Do not place it inside of the phpMyAdmin webroot. (In this example, the webserver runs as apache):

mkdir -p /var/tmp/phpMyAdmin
chown apache:apache /var/tmp/phpMyAdmin
chmod 700 /var/tmp/phpMyAdmin

Next, set TempDir inside of phpMyAdmin's config.inc.php:

$cfg['TempDir'] = '/var/tmp/phpMyAdmin';

Any answer suggesting that you create /usr/share/phpmyadmin/tmp is advocating bad security practice. This is generally true for temp directories, and explicitly stated in the official phpMyAdmin documentation:

For security reasons, all directories should be outside the tree published by webserver.

Answer 3

Create a tmp folder in the base directory of the phpMyAdmin install (e.g. /usr/share/phpmyadmin/tmp), and make sure that it is writable by the user that PHP is running under.

Answer 4

If the folder already exists for example from a previous installation:

chmod -R 777 PATH_TO_FOLDER

Therefore permission on subdirectories are also modified (recursively).

Answer 5

For me phpmyadmin dir was found inside /opt/lampp/

1. open teminal inside /opt/lampp/phpmyadmin/
2. give root privileges to the terminal by typing sudo su command.
3. now in same terminal use (mkdir -p /tmp/) hit enter
4. now, chmod 777 /tmp
5. Inside phpmyadmin directory there is a file config.inc.php. Open it using same terminal .
6. add this line $cfg['TempDir'] = /tmp; and Save.
7. Now you are good to go , just reload the tab and the error will be gone.

Answer 6

I just changed my vendor_config.php file to define('TEMP_DIR', '/tmp/'); instead of define('TEMP_DIR', './tmp/');

This seems to work.
