Nginx giving 404 error for WordPress' /wp-admin/ root - wordpress

Question

I have a Symfony2 application running alongside WordPress - mysite.com/blog routes to my /var/www/mysite/wordpress/ directory and everything else routes to /var/www/mysite/symfony:
server {
listen 80;
server_name mysite.com
location / {
try_files $uri /app.php$is_args$args;
}
location ~ ^/app\.php(/|$) {
fastcgi_pass 127.0.0.1:9000;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
internal;
}
location /blog {
root /var/www/mysite/wordpress;
rewrite ^/blog/(.+)$ /$1 break;
try_files $uri $uri/ /blog/index.php?q=$uri&$args;
index index.php;
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_split_path_info ^(?:\/blog)(.+\.php)(.*);
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
}
Everything works fine, except the WordPress admin (mysite.com/blog/wp-admin/) gives me a 404 error. Visiting mysite.com/blog/wp-admin/index.php works as expected, so it looks like the index index.php line is not working. What could be the issue here?

Answer 1

You should use alias instead of root directive:
location ^~ /blog {
alias /var/www/mysite/wordpress;
index index.php;
try_files $uri $uri/ /blog/index.php?q=$uri&$args;
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
include fastcgi_params;
fastcgi_split_path_info ^(?:\/blog)(.+\.php)(.*);
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}

You need to edit the nginx server Configuration.
# WordPress single blog rules.
# Designed to be included in any server {} block.
# This order might seem weird - this is attempted to match last if rules below fail.
# http://wiki.nginx.org/HttpCoreModule
location / {
try_files $uri $uri/ /index.php?$args;
}
# Add trailing slash to */wp-admin requests.
rewrite /wp-admin$ $scheme://$host$uri/ permanent;
# Directives to send expires headers and turn off 404 error logging.
location ~* ^.+\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
access_log off; log_not_found off; expires max;
}
# Uncomment one of the lines below for the appropriate caching plugin (if used).
#include global/wordpress-wp-super-cache.conf;
#include global/wordpress-w3-total-cache.conf;
# Pass all .php files onto a php-fpm/php-fcgi server.
location ~ [^/]\.php(/|$) {
fastcgi_split_path_info ^(.+?\.php)(/.*)$;
if (!-f $document_root$fastcgi_script_name) {
return 404;
}
# This is a robust solution for path info security issue and works with "cgi.fix_pathinfo = 1" in /etc/php.ini (default)
include fastcgi.conf;
fastcgi_index index.php;
# fastcgi_intercept_errors on;
fastcgi_pass php;
}

So, if you allege that /blog/wp-admin/index.php works, but /blog/wp-admin/ doesn't, perhaps just conditionally append index.php, if need be?
+ rewrite ^/blog/wp-admin(/)?$ /wp-admin/index.php break;
rewrite ^/blog/(.+)$ /$1 break;
So, what do the logs say in regards to your 404? I think this might be related to the fact that the index directive causes "an internal redirect", thus I would not be surprised if your 404 ends up being generated through the / instead of the /blog location.
