Upgrade to Debian Jessie

The new one Debian Stable has been a fact for about a week and my hands were itching to upgrade my virtual machine next to it but I didn't have any time until today. Since my day started early, I decided to dedicate time to the upgrade. I changed my source list by changing wheezy to jessie

sed -i "s/wheezy/jessie/g" /etc/apt/sources.list && apt-get update

They thundered here 2 mirrors:

  • MariaDB – from this mirror no longer needs Jessie includes a version 10.0.6 in myself which I didn't like very much. After 5.5 michetodb and mysql are not quite compatible which is why at the moment I turned back to mysql 5.5.42 – it is the default in jessie
  • DotDeb – i used it before for php55 here is also redundant because jessie comes with 5.6.7-1

After I lost the unnecessary mirrors and turned from MariaDB to Mysql apt-get dist-upgrade went clean, reboot and I was already with Debian 8.0. I opened my web server and to my surprise it worked here, the story is long – in a few words my Nginx is further compiled from source with additional directives. dpkg -l nginx-full 1.2 mdaaa someone forgot to unhold-not the packages. Unhold and upgrade everything is according to plan nginx broke 😆 . Nginx works processing requests and the php-fpm process is up and runnign but the php code does not execute and does not spit errors 🙄 MY FAVORITE.

After some searching for information about the changes, I found the following passage

Fastcgi configuration issues ============================

nginx shipped a modified fastcgi_params, which declared SCRIPT_FILENAME fastcgi_param. This line has now been removed. From now on we are also shipping fastcgi.conf from the upstream repository, which includes a sane SCRIPT_FILENAME parameter value.

So, if you are using fastcgi_params, you can try switching to fastcgi.conf or manually set the relevant params.

Bingo. I changed the virtual hosts to use fastcgi.conf instead of making rough interventions and everything worked. Then I hit a quick diff to see the difference between the 2 configs

diff /etc/nginx/fastcgi_params /etc/nginx/fastcgi.conf
> fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

Which reminded me that pouring large configurations into virtual hosts is not a cool idea. It remains to recompile my Nginx again with the add-ons I want mod_sec + pagespeed but this can wait. It is far more important, that my rule is repeated if you do not have the review from 3rd sources and custom performances Debian does not break at dist-upgrade!
