Why is there a hell of a rake with the Lemp/Lamp setting on the latest versions of Ubuntu/Fedora?

Question

System administration

Has anyone tried setting up LEMP on sockets on the latest versions? Ubuntu 16.04 is an unsuitable version of PhpMyAdmin, Fedora 23 with its reps and remays Remi again PhpMyAdmin is stupid. Authorization 500 error. It seems to be a problem with recording sessions, but they are written normally.
Everything seems to be fine on Ubuntu 14.04, but when upgrading to php7.0-fpm, export does not work in the same phpmyadmin.
They can’t do it normally out of the box, I don’t understand?

Answer 1

Your question is from the category "why is life shit?"
The 500th error has a reason. Open error.log at the server and you will see everything there.
The standard algorithm for finding an answer in 99% of cases on Unix systems
1) look at the logs of the demon
2) look at stdout, stderr (in short, what writes to the console) of the demon
3) copy the found error line to the clipboard
4) paste it into Google
5) profit!
Most likely already at stage 2, in cases it is more difficult at stage 3 you will already understand what the snag is.
