I am attempting to configure Nginx for everyone a wordpress install (along with a rails application - but this isn't the issue).

I've got a strange problem : I handled to obtain PHP work nicely (a fundamental test.php is properly parsed), however when I wish to install wordpress, Nginx send me the install.php file - I'm able to download it.

It is the only apply for which Nginx do this : another wordpress files too-offered, and do redirect to set up.perl for a longer period.

I'm on the Gentoo. Sometimes with spawn-fcgi here is below my nginx.conf. The concerning part may be the second server (wordpress.domain.local) :

    user nginx nginx;
    worker_processes 1;

    error_log /var/log/nginx/error_log info;

    events {
        worker_connections 1024;
        use epoll;
    }

    http {
        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        log_format main
            '$remote_addr - $remote_user [$time_local] '
            '"$request" $status $bytes_sent '
            '"$http_referer" "$http_user_agent" '
            '"$gzip_ratio"';

        }

    }

Try altering your try_files directive to try_files $uri $uri/ /index.php?$args; to handle query strings WordPress uses.
