Php file connection refused

PHP message: Connection refused

You log on to a server that is having performance issues, you do some basic troubleshooting only to find a PHP error log, several gigabytes in size, that contains just the one, particularly unhelpful, error message… over and over again.

[Wed Jun 04 13:24:18.154183 2021] [proxy_fcgi:error] [pid 817092:tid 139701387010829] [client 1002:41e0:6:b32a. 0] AH01234: Got error 'PHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refusedPHP message: Connection refused

The Cause

With such a generic error message it could be any number of things but in my case it turned out to be caused by W3 Total Cache for WordPress (W3TC). W3TC supports a number of different cache methods, this includes things like Redis and Memcached. If you have configured W3TC to use Redis and you have the incorrect connection settings or you are on shared hosting and don’t have the appropriate access you might end up with an error log that is spamming the phrase `PHP message: Connection refused` over and over again, dozens or hundreds of times a second.

It should be noted that this won’t stop the WordPress site from working, it might not even have a major performance impact, the first sign of a problem may even be the server running out of disk space.

The Solution

Switch to a disk based cache or reconfigure/get access to the caching service you have selected. Honestly this is pretty obvious once you actually know what the issue is.

Edit: It might also be worth double checking Redis/Memcached is actually installed as W3TC can sometimes show the option as active when it’s not actually installed on the server.

sudo systemctl status redis sudo systemctl status memcached

PHP- file_get_contents failed to open stream: Connection refused

and its working fine here and showing the country code.

But it showing error on Server

$IP=$_SERVER['REMOTE_ADDR']; $country_code = file_get_contents('http://api.hostip.info/country.php?ip=' . $IP); 

Warning:
file_get_contents(http://api.hostip.info/country.php?ip=101.63.xx.xxx)
[function.file-get-contents]: failed to open stream: Connection
refused in /srv/disk4/1322145/www/servername.in/app/header.php
on line 12

Best Solution

You can use CURL in place of file_get_contents()

Php – How to handle the warning of file_get_contents() function in PHP

Step 1: check the return code: if($content === FALSE) < // handle error here. >

Step 2: suppress the warning by putting an error control operator (i.e. @ ) in front of the call to file_get_contents(): $content = @file_get_contents($site);

Php – file_get_contents throws 400 Bad Request error PHP

You might want to try using curl to retrieve the data instead of file_get_contents. curl has better support for error handling:

// make request $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://api.twitter.com/1/statuses/user_timeline/User.json"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($ch); // convert response $output = json_decode($output); // handle error; error output if(curl_getinfo($ch, CURLINFO_HTTP_CODE) !== 200) < var_dump($output); >curl_close($ch); 

This may give you a better idea why you’re receiving the error. A common error is hitting the rate limit on your server.

php — File_get_contents(): failed to open stream: Connection refused

I am trying to download a previously uploaded file, form database and uploads folder in php codeigniter. I am using code below but downloading empty file.

 public function downloadFile($incidents_id) < $file = $this->incidents_model->getfile($incidents_id); //echo $file; die; $this->load->helper('download'); $path = file_get_contents(base_url()."uploads/".$file); //(the error shows on this line) // echo $path; die; $name = $file; // new name for your file // echo $name ; die; force_download($name, $path); // start download` > Copy code

 function getfile($Incident_id ) < $file = $this->db->select('file'); $this->db->from('incidents'); $this->db->where('incidents_id' , $Incident_id ); $query = $this->db->get(); // return $query->row(); if ($query->num_rows() > 0) < return $query->row()->file; > return false; > Copy code

so running this code download an empty file.

echo $file; die; displays the file name which been saved in db and in uploads folder

echo $path; die; generates an error: Severity: Warning

Message: file_get_contents(http://localhost:8080/ticketing_tool_v2/uploads/Screenshot 2021-03-04 at 5.59.38 PM.png): failed to open stream: Connection refused

Filename: admin/Incidents.php

Line Number: 380

Answer

Solution:

Reviewing the documentation for file_get_contents you’ll observe there’s many different ways you can use it. For your purposes you would need to allow inbound connections to the filesystem.

The other way you could do this for better future proofing is to use the CodeIgniter file helper — https://codeigniter.com/userguide3/helpers/file_helper.html

Answer

Solution:

Before reading the file from path, please check whether a path points to a valid file.

public function downloadFile($incidents_id) < try < $this->load->helper('download'); $file = $this->incidents_model->getfile($incidents_id); $data = file_get_contents(base_url("uploads/" . $file)); $name = $file; // new name for your file force_download($name, $data); // start download` > catch (Exception $e) < //exception handling code goes here print_r($e); >> Copy code
