Answer 1

You can try to use RedisException class to debug your redis connection.

try{
  if( $socket = fsockopen( $host, $port, $errorNo, $errorStr )){
    if( $errorNo ){
      throw new RedisException(“Socket cannot be opened”);
   }    
  }
}catch( Exception $e ){
  echo $e -> getMessage( );
}

I will elaborate on the answer once you are able to give an exception or an error.

Did you check if your php redis module is loaded by checking in phpinfo() ? Also, if your redis server is running properly and on which port and if configured using password you are supplying same while initiating the connection ?
