Apache works with php7, but crashes with php5

  • 772

I have upgraded to Ubuntu 16.04 recently, and everythings works perfectly but I need php5, which is not in the official repositories. So I have tried with phpbrew: it didn't work (it was unable to switch to any php version).

Then I have found this question: How can I downgrade from PHP 7 to PHP 5.6 on Ubuntu 16.04?

The accepted answer looked perfect to me, so I have disabled phpbrew and installed all the packages. Everything seemed correct, but still php7 works correctly, and when I switch to php5 apache fails to load.

In /var/log/apache2/error.log I see this:

[Wed May 18 12:15:21.596482 2016] [mpm_prefork:notice] [pid 31446] AH00169: caught SIGTERM, shutting down

And if I do service apache2 status I see this:

mag 18 12:20:01 portatilone systemd[1]: Starting LSB: Apache2 web server...
mag 18 12:20:01 portatilone apache2[32670]:  * Starting Apache httpd web server apache2

How can I make apache work with php5?

  1. Fixed by purging both apache and php. Only removing php was not sufficient. I'm not sure that this is the best way to do it, but it worked:

    sudo service apache2 stop
sudo apt-get remove --purge apache2 apache2-utils apache2-bin php*
sudo apt-get autoremove

    And this is what I used to reinstall everything: https://askubuntu.com/a/762161/411578
