How to set up sendy on nginx?

Question

PHP

Help someone to run sendy on nginx correctly.
My config, what's wrong here?

upstream php-fpm
{
  # PHP5-FPM сервер
  server unix:/var/run/php5-fpm.sock;
}

server
{
     listen 3000; 

    root			/srv/sendy;
    index			index.php;
    server_name		_;
    autoindex off;



    access_log /srv/sendy/logs/access.log;
    error_log /srv/sendy/logs/error.log;

    location / {
        try_files $uri $uri/ $uri.php?$args;
    }

    location /l/ {
        rewrite ^/l/([a-zA-Z0-9/]+)$ /l.php?i=$1 last;
    }

    location /t/ {
        rewrite ^/t/([a-zA-Z0-9/]+)$ /t.php?i=$1 last;
    }

    location /w/ {
        rewrite ^/w/([a-zA-Z0-9/]+)$ /w.php?i=$1 last;
    }

    location /unsubscribe/ {
        rewrite ^/unsubscribe/(.*)$ /unsubscribe.php?i=$1 last;
    }

    location /subscribe/ {
        rewrite ^/subscribe/(.*)$ /subscribe.php?i=$1 last;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }

    location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ {
        access_log off;
        log_not_found off;
        expires 30d;
    }
}

At the entrance, it redirects to _install.php, I can’t figure out why. Maybe someone has already done this?
