Using phpsysteminfo with PHP-FPM

Sparkie · December 27, 2020, 10:55pm

Hi all. Hope you are all well.

Can anyone help me get phpsysteminfo working with Hestia (Apache & PHP-FPM)?
The only way I can get it working is to not use PHP-FPM and use the web template “phpfcgid” on a test install.

I understand if its a security thing, but I really like using phpsysinfo to monitor my server.
It seems it does not have permission to access the required info:

file_exists(/proc/uptime) - the file does not exist on your machine
file_exists(/proc/loadavg) - the file does not exist on your machine
file_exists(/proc/stat) - the file does not exist on your machine
file_exists(/proc/cpuinfo) - the file does not exist on your machine
file_exists(/proc/meminfo) - the file does not exist on your machine

Is it possible in any way to allow PHP-FPM access to the required data?

Thanks for any help!

We have limited access to this files due to an safety issue

Don’t know if there is an easy fix for it

Checkout the following part

github.com

hestiacp/hestiacp/blob/4b4edd540ffde7f17a364aa3911c11b71b477eab/install/hst-install-debian.sh#L938


    sed -i 's/#allowrsync/allowrsync/' /etc/rssh.conf
    chmod 755 /usr/bin/rssh
fi
# Restrict access to /proc fs
# - Prevent unpriv users from seeing each other running processes
mount -o remount,defaults,hidepid=2 /proc > /dev/null 2>&1
if [ $? -ne 0 ]; then
    echo "Info: Cannot remount /proc (LXC containers require additional perm added to host apparmor profile)"
else
    echo "@reboot root sleep 5 && mount -o remount,defaults,hidepid=2 /proc" > /etc/cron.d/hestia-proc
fi
#----------------------------------------------------------#
#                     Configure Hestia                     #
#----------------------------------------------------------#
echo "[ * ] Configuring Hestia Control Panel..."
# Installing sudo configuration
mkdir -p /etc/sudoers.d

It limits the acceess to proc as a security feature. You can remove /etc/cron.d/hestia-proc and reboot your server.

Thank you so much for your help ScIT. This however has not made it work for me.
Is it PHP that is unable to read /proc?
If I do
cat /proc/loadavg
from my user account, or the admin account, I get the correct result and see the load averages, but phpsysinfo is still unable to read them saying that the file does not exist.
Thanks, John.

Probaly additional changes are needed, never used that script. Maybe have a look what @eris wrote in discord:
@thanior Probally alter openbase dir to allow /proc And maybe other config things

make sure your php.ini file’s include_path entry contains “.” make sure your php.ini has safe_mode set to ‘off’.

OK, I managed to figure this out. It was the PHP open_basedir setting, which is in php.ini but gets overruled by the PHP-FPM backend template. Here’s what I did:

cd /usr/local/hestia/data/templates/web/php-fpm/
sudo cp default.tpl default_phpsysinfo.tpl
sudo nano default_phpsysinfo.tpl

Change the line:

php_admin_value[open_basedir] = /home/%user%/web/%domain%/public_html:/home/%user%/web/%domain%/public_shtml:/home/%user%/tmp:/var/www/html:/etc/phpmyadmin:/var/lib/phpmyadmin:/etc/phppgadmin:/etc/roundcube:/var/lib/roundcube:/tmp:/bin:/usr/bin:/usr/local/bin:/usr/share:/opt

To:

php_admin_value[open_basedir] = none

Then in the Hestia control panel, edit the web domain that hosts your phpsysinfo and change ‘Backend Template PHP-FPM’ to ‘default_phpsysinfo’ and magic, enjoy your phpsysinfo!

I should add, my server is only accessed by me, so I don’t think this will be a problem. I do use phpsysinfo a lot to monitor my server and am glad to have it back using PHP-FPM

Thanks for such a great project.
