Format error in Systemd Exec files

Using virtualmin-lemp-stack, everytime you create a server a php-fcgi-wrapper process was created.

Now no process is being created, so the socket referenced by nginx configuration points to an inexistent unix:/var/php-nginx/SERVER_ID.sock/socket which results in 502 errors.

No error entries in the log and the GUI states that everything is A_OK:

Looking arround I came across this: https://www.virtualmin.com/comment/831037#comment-831037

As it turns out Virtualmin is creating the process in systemd instead of inid.d, which is awesome... but it's done the wrong way...

● php-fcgi-domain-com.service - Starts Nginx PHP FastCGI server for domain.com (Virtualmin)
   Loaded: error (Reason: Exec format error)
   Active: inactive (dead)

systemd requires all paths to be absolute, and there are two paths that aren't: - su - sleep

So as a workaround I prepended /bin/ to the commands and now... everything works! Still the Exec files are in the wrong format and this should be remedied.

This bug should be fixed in Webmin 1.973. Is the config still bad for new domains you create after upgrading Webmin?

Hi there!

I just upgraded.

It's still not working, There's a /bin/ missing in the ExecStop entry; specifically in the last ; sleep 1

After adding it, running systemctl daemon-reload the process could be started without any problems.

As a "footnote", there are a lot of these:

Use of uninitialized value $mode in string ne at /usr/share/webmin/virtualmin-nginx/virtual_feature.pl line 940.

In the upgrade log.

Regards

This has been fixed a while ago. However, I never made a new release, as there were few more bugs to fix, which I wanted Jamie to have a look at.

I assume, Jamie was busy, so nevermind, I will have a closer look then, and provide an update within few next days.

We can do a new Nginx plugin release now to fix this one

Yes, Jamie. Just yesterday, I have already included all of the patches needed, and tagged a new release for both Nginx and Nginx SSL Virtualmin modules. It should be out within 24h hours.
