How can I Connect to other server

Question

I want to make a platform to get disk space usage of several server. How i can do it?

$df = disk_free_space("/");

i want this line of code to be executed on my all servers

Answer 1

仅使用php并非易事，甚至不可能，我认为最好的解决方案是将带有curl的请求发送到服务器，以返回磁盘空间使用率。

Answer 2

One way is to use the ssh2_XXX functions of PHP to login to each server and run df / .

Another way is to create a web page on each server that runs disk_free_space('/') and echoes the result. Then you can use file_get_contents("http://servername/disk_free.php") to query each server.

Answer 3

There are many ways to do this. Curl is an option, you can use cron on each server, that runs at specific time and updates the value to a web server, or you can use ssh to get the same info.

Answer 4

on each server, you can insert a page that returns the free space:

• http://server1.com/GetFreeSpace.php
• http://server2.com/GetFreeSpace.php
• http://server3.com/GetFreeSpace.php

GetFreeSpace.php

<?php
echo disk_free_space("/");

You can use cURL to query several servers

<?php
$ch = curl_init();

curl_setopt_array($ch, array(
    CURLOPT_URL => 'http://server1.com/GetFreeSpace.php',
    CURLOPT_RETURNTRANSFER => true
));

echo curl_exec($ch);
