The Perfect Server - Debian 11 (Bullseye) ?

The recommended installation method on Debian 11 is the auto-installer, the guide has been updated for Debian 11 quite some time ago. Might be that I'll write an update for the old Debian perfect server guide though if I have some spare time.

 

I meant this guide:

https://www.howtoforge.com/ispconfig-autoinstall-debian-ubuntu/

 

What is your default shell? On a plain system, the AI should run fine and change the default shell to Bash for later.

Why are you changing it in the panel?

Do you have "The network configuration option is only available for Debian and Ubuntu Servers. Do not enable this option if your network interface is not eth0." checked? You should not use that anymore in most cases.

 

What was the error you saw?

Default name? The guide clearly instructs you to use your own hostname when setting up the server - not server1.example.com, that's just a placeholder in the guide.

 

This error is not related to bash vs. dash at all and you verified yourself that changing to bash upfront is not needed as the installer reconfigures the shell correctly from dash to bash.

 

Just to finish up this topic, I ran the auto-installer on a Debian 10.12 system, it worked flawlessly, no change of dash to bash required upfront and mailman was installed too. Here is the whole install output, I just removed some apt output lines at the beginning to make it easier readable.

Code:

/usr/bin/sh

And the auto-installer even mentions the shell change btw:

Code:

[INFO] Default shell is currently dash.
[INFO] Setting bash as default shell.
[INFO] Default shell is now bash.

 

Use "su -" or "sudo -i".

You can only load one version of mod_php at a time; my guess is that your site requires an older version of php, and you are now using php 5.6 for it so it works, but it failed with newer php under both fpm and fast-cgi modes. That's just a guess, it could be you need to install additional php modules, etc. You can do what you want here, but I would purge all mod_php packages from the system, set the site to fpm mode, create a small phpinfo page and see if it loads, then troubleshoot from there. If the phpinfo page loads, try loading the site and check the php error log to see what's going on (also check the software requirements for that site, eg. php version and modules); if the phpinfo page doesn't load, something is broken in the fpm setup (and my above guess is wrong), check starting/stopping the daemon manually, check log files for errors, etc.

 

You use the wrong command. Since Debian 10, one has to use:

su -

But that's not ISPConfig related in any way, the way recent su versions work has been changed. Btw, we do mention that even in the perfect server install guides.

I run quite a few Debian 10 and 11 systems, all installed according to the perfect server guide or using auto-installer, and none of them has any issues with php-fpm. So most likely you did some modifications in your setup which make it differ from a standard install that cause this. The apache mod_php module is not related to running PHP scripts by php-fpm.
