My site is running on apache. two instances of wordpress exist under paths /tr/ and /eng/. I want to move the setup to nginx but could not manage to get it working.

My setup consists of nging 0.7.66, php 5.3.2, and php-fpm. /tr/ and /eng/ are two separate wordpress instances located under /home/istci/webapps/wordpress_tr and /home/istci/webapps/wordpress respectively.

Below is the server section from nginx.conf containing only configuration for tr, yet could not get it working either.

server {
    listen       80;
    server_name  www.example.com;

    charset utf-8;

    location ~ ^/$ {
        rewrite ^(.+)$ http://www.example.com/tr/ permanent;
    }

    location ~ /tr/.*php$ {
        fastcgi_pass   unix:/home/istci/var/run/wptr.sock; 
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME    /home/istci/webapps/wordpress_tr$fastcgi_script_name;

        fastcgi_param  QUERY_STRING       $query_string;
        fastcgi_param  REQUEST_METHOD     $request_method;
        fastcgi_param  CONTENT_TYPE       $content_type;
        fastcgi_param  CONTENT_LENGTH     $content_length;

        fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
        fastcgi_param  REQUEST_URI        $request_uri;
        fastcgi_param  DOCUMENT_URI       $document_uri;
        fastcgi_param  DOCUMENT_ROOT      $document_root;
        fastcgi_param  SERVER_PROTOCOL    $server_protocol;

        fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
        fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

        fastcgi_param  REMOTE_ADDR        $remote_addr;
        fastcgi_param  REMOTE_PORT        $remote_port;
        fastcgi_param  SERVER_ADDR        $server_addr;
        fastcgi_param  SERVER_PORT        $server_port;
        fastcgi_param  SERVER_NAME        $server_name;

        # required if PHP was built with --enable-force-cgi-redirect
        fastcgi_param  REDIRECT_STATUS    200;
    }


    location /tr/ {
        root   /home/istci/webapps/wordpress_tr/;
        index  index.php index.html index.htm;


        if (!-e $request_filename) {
            rewrite ^(.+)$ /tr/index.php?q=$1 last;
            break;
        }

        if (-f $request_filename) {
            expires 30d;
            break;
        }

    }
}

php-fpm listens on unix:/home/istci/var/run/wptr.sock. running it in debug-mode shows no active handlers, which means no connection is made to unix socket from nginx.

Any clues about what is wrong with my configuration? Thanks.
