File not found nginx php-fpm - php

Question

I've looked through every question like this here and tried to apply the stated fixes with no success.
I'm using the wordpress:4.7.3-php7.0-fpm-alpine docker image with a separate nginx container in front of it.
When I curl wordpress I get:
File not found.
When I check the wordpress container logs, I get:
127.0.0.1 - 16/Mar/2017:06:26:24 +0000 "GET /index.php" 404
127.0.0.1 - 16/Mar/2017:06:31:27 +0000 "GET /index.php" 404
127.0.0.1 - 16/Mar/2017:06:32:16 +0000 "GET /index.php" 404
127.0.0.1 - 16/Mar/2017:06:37:17 +0000 "GET /index.php" 404
127.0.0.1 - 16/Mar/2017:06:39:09 +0000 "GET /index.php" 404
The actual nginx error is:
2017/03/16 06:26:24 [error] 17#17: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 10.128.0.7, server: k8wp, request
: "GET / HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000"
I'm using php 7
/var/www/html # php-fpm -v
PHP 7.0.16 (fpm-fcgi) (built: Mar 3 2017 23:07:56)

My nginx config is
server {
root /app;
# Add index.php to the list if you are using PHP
index index.php index.html index.htm index.nginx-debian.html;
server_name _localhost;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
I'm running nginx as the user www-data:
user www-data;
According to /usr/local/etc/php-fpm.d/www.conf the user and group are uncommented and set to www-data

Answer 1

The error indicates that your SCRIPT_FILENAME is incorrect. Your comment:
in the wordpress container it's at /var/www/html/index.php in the
nginx container it's at /app
suggests that nginx and php-fpm are seeing a different document root.
In which case, use:
fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

Answer 2

You can try to include include snippets/fastcgi-php.conf;. It should fix your problem.

Answer 3

The issue I had with this was that my wordpress install was in a subdirectory. So the /blog/ main index of wordpress would load, but none of the published blog entries or pages in deeper directories such as /blog/wp-admin/ would load.
To fix this, I added this block:
location /blog {
try_files $uri $uri/ /blog/index.php?$args;
}
This is actually explained in "Location Strategies" of the nginx wordpress recipes page.

Answer 4

My issue was due to serving the website's folder from within user's home folder.
Once I moved it from /home/ubuntu/my-website to /srv/my-website all worked fine.
