How to Upgrade phpMyAdmin manually?
I am using PHP7.2 for one of my projects and facing compatibility issues while working in phpMyAdmin 4.6. I do some Google and find out a solution. So in this article, we will go through the process of how to upgrade phpMyAdmin 4.6 to 4.9 to solve the issue.
The issue/warning we are facing:
Warning in ./libraries/sql.lib.php#613 count(): Parameter must be an array or an object that implements Countable
Why we get this warning: Please check this link for details – https://wiki.php.net/rfc/counting_non_countables
Let’s start…
Step 1: Backup existing phpMyAdmin
1.1 First thing Fast, Save your Ass. Back up our existing phpMyAdmin folder by renaming it.
sudo mv /usr/share/phpmyadmin/ /usr/share/phpmyadmin_bakup
1.2 Create a new phpMyAdmin folder
sudo mkdir /usr/share/phpmyadmin/
1.3 Change the directory to
cd /usr/share/phpmyadmin
Step 2: Download the latest version phpMyAdmin and extract it.
2.1 Go to the phpMyAdmin download page and find out the latest stable version. In my case I am using “phpMyAdmin-4.9.1-all-languages.zip”
2.2 If you already have wget package installed in the OS then skip it, otherwise install wget
sudo apt-get update
sudo apt-get install wget
2.3 Now download the latest stable version of phpMyAdmin and make sure to change the command below. And let me know in the comment that I can update this article for others.
sudo wget https://files.phpmyadmin.net/phpMyAdmin/4.9.1/phpMyAdmin-4.9.1-all-languages.zip
2.4 If you don’t have unzip package installed then install the unzip by otherwise skip this step
sudo apt-get install unzip
2.5 Now extract.
sudo upzip phpMyAdmin-4.9.1-all-languages.zip
Once extracted list folder
ls
You should see a new folder phpMyAdmin-4.9.1-all-languages
2.6 Now we are going to move the content of this folder to /usr/share/phpmyadmin
sudo mv phpMyAdmin-4.9.1-all-languages/* /usr/share/phpmyadmin
Now you can log back into phpMyAdmin on your browser and check the current version. You may also notice two errors at the bottom of the page
“The configuration file now needs a secret passphrase (blowfish_secret)”
“The $cfg[TempDir] (./tmp/) is not accessible. phpMyAdmin is not able to cache templates will be slow because of this”
So, let’s fix these error too in the next steps
Step 3: To fix these two errors we need to update vendor_config.php file
3.1 Open vendor_config.php file
sudo nano /usr/share/phpmyadmin/libraries/vendor_config.php
3.2 Press Ctrl+w to search TEMP_DIR
Change line to
define(‘TEMP_DIR’, ‘/var/lib/phpmyadmin/tmp/’);
3.3 Again press Ctrl+w and search CONFIG_DIR
Change line to
define(‘CONFIG_DIR’, ‘/etc/phpmyadmin/’);
3.4 phpMyAdmin now generates its own blowfish secret based on the install directory
Save the file and exit by pressing Ctrl+x, press y and then press enter.
Step 4: Cleaning-up
4.1 I hope now everything is ok. Now you can delete the downloaded .zip file and empty the directory
sudo rm /usr/share/phpmyadmin/phpMyAdmin-4.9.1-all-languages.zip
sudo rm -rf /usr/share/phpmyadmin/phpMyAdmin-4.9.1-all-languages
4.2 Now make sure your new upgraded phpMyAdmin is working fine, then you can also delete the backup directory
sudo rm -rf /usr/share/phpmyadmin_bakup
