Upgrade to Ubuntu16.04 LTS from 14.04 LTS killed my php

Hi Purvez,

I am going through a similar upgrade, here is what I found necessary (so 

1) Swap back from sockets to a normal port. As root, edit 
     # nano /etc/php/7.0/fpm/pool.d/www.conf
Find listen and change to
     listen =
     listen.allowed_clients =

Your nginx configs much match.

2) Check all mysql fields in all user databases - all fields you do not 
explicitly write MUST now have a default. The older MySQL was a lot more 
forgiving - E.g. unset varchar() field became "", but no longer.
All but one of my changes were to varchar() fields.

3) Check all GROUP BY statements. You may have to add a ANY_VALUE() 
round a field if you get a error about not being compatible with the 
ONLY_FULL_GROUP_BY mode (default has changed). MySQL will now reject 
queries for which the select list, HAVING condition, or ORDER BY list 
refer to non-aggregated columns that are neither named in the GROUP BY 
clause nor are functionally dependent on (uniquely determined by) GROUP 
BY columns.

4) secure php7-fpm - edit /etc/php/7.0/fpm/php.ini and find the line
defining cgi.fix_pathinfo. Uncomment the line and set the value =0.

5) You may have to install and enable mcrypt and mbstring (as root)
     # apt install php7.0-mcrypt php7.0-mbstring
     # phpenmod mcrypt
     # phpenmod mbstring

Your mileage will probably vary, but I hope this helps you avoid some 
ditches you might otherwise fall into.
