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

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;
    }
}
