sphinxsearch returns "failed to send client protocol version"

On some of my servers, doing a sphinx php query returns that error. Searching google I can't find anything except this is part of why the error came out:

// send my version
    // this is a subtle part. we must do it before (!) reading back from searchd.
    // because otherwise under some conditions (reported on FreeBSD for instance)
    // TCP stack could throttle write-write-read pattern because of Nagle.
    if (!$this->Send($fp, pack('N', 1), 4))
    {
      fclose($fp);
      $this->error = 'failed to send client protocol version';
      return false;
    }

The close I've found is this http://www.sphinxsearch.com/forum/view.html?id=4919

But I do not know where the sphinxapi.php is (I installed using manual compile) and not sure if that's a good idea.

Anyone has any idea?

I have the same problem with Sphinx 2.2.8

What I found is in this version the set of listen port in searchd configuration was removed and now the ports are

listening on all interfaces, port=9312
listening on all interfaces, port=9306

So when you configure the sphinx client use port 9312 works for me. Ie:

$sphinxClient = new SphinxClient()
$sphinxClient->SetServer("localhost", 9312);

Hope this helps you. And if you need more details about the basic configuration just ask me.

The issue can be with the wrong port. I had two ports set for listening in my sphinx.config:

searchd{
   listen = 9312
   listen = 9306:mysql41
}

When I've tried to connect via 9306 port, I got the error mentioned above. Changing it to 9312 solved the problem.

First of all make shure that you use suitable ip for api library. What ip is using you can see into

sphinx.config section searchd{}.

If it is ok next step is to see sphinx status

searchd --status

I just had the same issue on my server, and I realized I did not start the searchd daemon at all.

Hope this helps
