Can not switch to fpm mode

Submitted by gnilebein on Mon, 07/10/2017 - 03:46

Currently I can not switch php execution mode to fpm. Existing servers with fpm still runs fine.

I am using Ubuntu 16.04 with nginx and php7 shipped with the os.

Howdy -- what output do you receive if you go into System Settings -> Re-Check Configuration?

However, I believe the behavior you're experiencing is expected, in that I think switching PHP Execution Modes is only supported when using Apache.

As Eric has mentioned, I too believe the "Website Options" page is primarily designed for Apache usage. Since Apache has been around since the beginning, it's quite possible you'll notice a lot of features that are slanted in it's direction as nginx support is fairly new in comparison.

The config check tells me everything is fine. Screenshot_20170711_001724

It has worked in the past. Since the installation of my two server I am using Nginx. And I changed the mode for my domain to fpm on the page shown above... so the fpm feature was available in the past....

Please see the changelog on github...

https://github.com/virtualmin/virtualmin-nginx/blob/master/CHANGELOG

Added support for FPM as an execution mode, if Virtualmin 5.06 and FPM packages are installed.

So where can I change the mode if not there...

FPM mode should work under Nginx, as long as the needed packages are installed on your system.

Do any of the directories matching /etc/php-fpm.d , /etc/php*/fpm/pool.d or /etc/php/*/fpm/pool.d exist on your system?

Submitted by gnilebein on Mon, 07/10/2017 - 20:32

/etc/php/7/fpm/pool.d exists and there are many pools for domains switched to fpm in the past.

gnilebein - did the ability to select FPM mode suddenly stop working when you upgraded to Virtualmin 5.99 ?

I can't say it exactly but it seems so.

Hello @ll,

I did some more tests:

  1. Generally the fpm detection seems to work. I can select it as default mode in server templates.

Screenshot_20170712_223138

  1. If the default mode is selected and I create a new server, virtualmin create a fpm pool and the new server is running in fpm mode.

Screenshot_20170712_224044

But I still can not switch the mode manually for existing servers.

What if you use a shell API command, like virtualmin modify-web --domain yourdomain.com --mode fpm

Submitted by gnilebein on Fri, 07/14/2017 - 00:47

root@server01:~# virtualmin modify-web --domain server01.gnilebein.de --mode fpm             
The selected PHP exection mode cannot be used with server01.gnilebein.de

I tried it with da fresh installation of Ubuntu 16.04 and virtualmin (with NGinx) an i got the same problem.

If you need access to my server for testing purposes just sent me an your SSH Public Key and i will create an account for you.

Ok, it looks like the issue is that FPM support isn't installed on your system.

You should be able to fix this by running apt-get install php-fpm as root. Then run virtualmin check-config to see if it reports if FPM mode is enabled ... and if not, why not.

BTW: I tried the command on a server where FPM is not installed. There was no report that is is not installed with that command....

And PHP FPM ist already running for many servers:

Odd that there was no mention at all of FPM support in the check-config output. Is this system running Virtualmin 5.99 ?

Submitted by gnilebein on Mon, 07/17/2017 - 23:49

Yes it is.

Try it now - I found a bug in the code that checks for FPM support where it was looking for a particular Apache feature, even when Apache wasn't installed!

Submitted by gnilebein on Tue, 07/18/2017 - 00:18

Thank you for your help. That sounds good. So this bug will be fixed in the 6.0 release?

Submitted by JamieCameron on Tue, 07/18/2017 - 19:38

Yes, the fix will be included in the 6.0 release.
