Have trouble installing phpmyadmin on PHP7 Apache/2.4.7 (Ubuntu) - php

Question

I installed PHP7 today with
sudo add-apt-repository ppa:ondrej/php-7.0
sudo apt-get install php7.0-cli php7.0-common libapache2-mod-php7.0 php7.0 php7.0-mysql php7.0-fpm
after this, I got 403 forbidden error when I tried to access phpmyadmin.
then I tried to reinstall phpmyadmin with
apt-get install phpmyadmin
but it still looks for php5 dependencies which arent there anymore:
what can I do to solve this?

Answer 1

Install it via wget and create an alias in Apache. Keep track:
Change to directory /usr/share:
cd /usr/share
Change to root user:
sudo su
Download phpMyAdmin:
wget https://files.phpmyadmin.net/phpMyAdmin/4.5.4.1/phpMyAdmin-4.5.4.1-all-languages.zip
Unzip it: (you may install unzip first)
unzip phpMyAdmin-4.5.4.1-all-languages.zip
Rename the folder:
mv phpMyAdmin-4.5.4.1-all-languages phpmyadmin
Change permissions:
chmod -R 0755 phpmyadmin
Configure apache so that it can find it correctly:
vim /etc/apache2/sites-available/000-default.conf
Anywhere after "DocumentRoot /var/www/html" insert these line:
Alias /phpmyadmin "/usr/share/phpmyadmin/"
<Directory "/usr/share/phpmyadmin/">
Order allow,deny
Allow from all
Require all granted
</Directory>
Restart Apache:
service apache2 restart
And you are ready to go!
Just took a screenshot from my current installation for you to validate it works.

Answer 2

phpMyAdmin depends on the extension mbstring.
For Debian users (tested in Ubuntu 15.10),
sudo apt-get install php7.0-mbstring
For Fedora and CentOS,
sudo yum install php70w-mbstring

Answer 3

Using git clone of the original repo with a daily update cron job as documented here https://laracasts.com/discuss/channels/general-discussion/phpmyadmin-with-php7 worked really well for me. I put the following in my Vagrantfile (for a development server)
if [ ! -d /usr/share/phpmyadmin ]; then
sudo mkdir /usr/share/phpmyadmin
sudo git clone --depth=1 --branch=STABLE https://github.com/phpmyadmin/phpmyadmin.git /usr/share/phpmyadmin
fi
then added the alias as above
Alias /phpmyadmin "/usr/share/phpmyadmin/"
<Directory "/usr/share/phpmyadmin/">
Order allow,deny
Allow from all
Require all granted
</Directory>
and
service apache2 restart
very easy, only a few steps, always up to date. (Ubuntu wily, php7)

Answer 4

Before installing PHP 7 you should backup your database. During the installation process, you will delete your old version of php and be asked if you want to delete your database. Don't do it unless you really want to get rid of it.
Download phpmyadmin from https://www.phpmyadmin.net/ and uncompress it and move the folder to one level below the document root folder. It then worked for me when I navigated to it with localhost without further setup. I had to erase my bookmarks to phpmyadmin and make new bookmarks for the new location. My old database was fine.
I would like to install phpmyadmin globally so it could be installed or reinstalled or updated by apt-get, but don't know how.

Answer 5

I followed Magnus Eriksson's suggestion from comments
Try to install the latest version manually by downloading phpmyadmin
from their website. In all fairness, phpmyadmins apt-repo has
dependencies to other packages in the official apt-repo. PHP7 doesn't
exist in the apt-repo. (you added it manually, which phpmyadmins repo
has no clue about).
