Question

PHP

How to connect in php via ssh, and find out the amount of free disk space on the server and send it to php?

Answer 1

The easiest way is to get an SSH key to log in without a password, and write in php and then parse $out;
$out = shell_exec("ssh [email protected] 'df -BM'");

Answer 2

You can use Deployer , Envoy , or just exec( ). But it is better to use some kind of agent that will constantly work on the server and give the information we need on a simple request to the selected port or on a regular basis, via the API. Well, for example, on the server we create a cron task that will run a console php script once an hour and put the information into a json file. Then we can get disk space with a simple request to this json, without suffering from ssh requests to the server and without opening a potential security hole.

Answer 3

It is better to use zabbix for these purposes
. It has api and packages for php
