Proper Nginx PHP5-FPM UNIX Socket Configuration To Avoid Bad Gateway and Timeout Errors like :
connect() to unix:/var/run/php5-fpm.sock failed
upstream timed out ( : Connection timed out)
connect() to unix:/tmp/php5-fpm.sock failed ( : No such file or directory)
Full Guide : https://thecustomizewindows.com/2015/03/ubuntu-nginx-php5-fpm-unix-socket-configuration/
You'll not get the whole stuff anywhere as a single piece. If php5-fpm.sock is not present, how much you edit /etc/php5/fpm/pool.d/www.conf, it will never work.
Next, nginx must be a member of www-data user group. The Gateway errors on WordPress Nginx PHP5-FPM are usually due to Nginx Microcache.
It will work on :
PHP PHP 5.5.9 and above (CLI) +
- Ubuntu Nginx Community Edition or Ubuntu Nginx Plus Trial or Ubuntu Nginx Plus Full
Thanks : Thanks to Nginx Plus team for the smallest hint towards Microcache related problem.
Usage Limititation : You should pay us for commercial usage. It is under GNU GL 3.0. If you drink my blood to earn money, I have no problem but think a bit about Karma.
