Wordpress not loading on shared NGINX server name - php

Question

I am successfully running a Wordpress installation alongside Meteor using NGINX. I have no real experience with Wordpress or php, so this may be a simple fix.
The following configuration works:
server_tokens off;
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
upstream mydomain-production {
server localhost:8000;
}
# redirect all non-subdomain traffic to https
server {
listen 80;
server_name www.mydomain.com mydomain.com;
rewrite ^ https://$host$request_uri? permanent;
access_log /var/log/nginx/mydomain.access.log;
error_log /var/log/nginx/mydomain.error.log;
}
# this non-subdomain serves meteor correctly
server {
listen 443 ssl spdy;
server_name www.mydomain.com mydomain.com;
access_log /var/log/nginx/mydomain.secure.access.log;
error_log /var/log/nginx/mydomain.secure.error.log debug;
ssl_certificate #...removed...# ;
ssl_certificate_key #...removed...# ;
ssl_stapling on;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 5m;
ssl_prefer_server_ciphers on;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers #...removed...# ;
add_header Strict-Transport-Security "max-age=31536000;";

# this temporary subdomain serves wordpress correctly
server {
listen 80;
server_name wordpress.mydomain.com;
access_log /var/log/nginx/mydomain.access.log;
error_log /var/log/nginx/mydomain.error.log;
index index.php index.html index.htm;
root /var/www;
location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location /50x.html {
root /usr/share/nginx/html;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_intercept_errors on;
include fastcgi_params;
}
}
So since I have Wordpress functioning on a temporary subdomain, I want to make it work on the same domain as Meteor and include location directives to route certain requests to Wordpress instead.
I tried adding the following to the 443 server name:
# additional code
location /blog {
root /var/www;
try_files $uri $uri/ /index.php?q=$uri&$args;
index index.php index.html index.htm;
}
location /wp-admin {
root /var/www;
try_files $uri $uri/ /index.php?q=$uri&$args;
index index.php index.html index.htm;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_intercept_errors on;
include fastcgi_params;
}
After doing this, I get an NGINX 404 page at mydomain/blog. So the location directive is successfully sending the request to /var/www instead of Meteor, but for some reason it is not getting to the Wordpress router. I have linked my NGINX error debug output here.

Answer 1

This was somehow solved by simply moving the root /var/www; and index index.php index.html index.htm; outside of the location directive(s). I would be interested to know why this is necessary if anyone can shed any light on this.
