[Fli]

What are the best server control panels for website hosting, that are free and works on Linux?

Maybe most feature rich are paid cPanel and DirectAdmin(cP to DA migration tutorial).

But if one do not wish to pay like $20+ monthly just for control panel, then there are DirectAdmin & cPanel reseller hosting accounts or a nice free control panels below:

VestaCP (Nginx, 512MB RAM+,20GB HDD)
BrainyCP (CentOS, 1GB RAM 1GB SWAP)
CyberPanel (1GB RAM+)
Sentora (zPanel successor) (requires minimal Linux and supports Apache only, 256MB RAM+)
ISPConfig (fast and secure - 911racks - how to install it? #1, #2, #3)
KloxoMR (developer not much active, i think it would work on 256MB RAM+)
KeyHelp - (recommend at least 1GB of RAM, Ubuntu 12,14 + Debian 8)
AlternC (not tried, but demo looks very easy to work with)
Webmin (lightweight, very verstatile, claimed not to be as secure as ISPConfig, made for the professional server admins, not newbies that just want to host a site, use authentic theme)
CentMinMod (command line based, good if performance important and high visitors, 256MB RAM+)
VPSSIM (command line based, good if performance important and high visitors, 512MB RAM+)
yunohost - 512MB RAM min. 1GB recommended, 500Mhz CPU min., https://yunohost.org/#/whatsyunohost
CentOSWebPanel - claimed to be insecure, but has nice UI

Do you know any other easy to use hosting control panels that are free?

zPanel
Webmin

zPanel is outdated, its successor is Sentora.
Webmin i think is hard to work with if you are not experienced server admin and just want to host a website
