[Pkg-nginx-maintainers] Bug#1028155: I know what the problem is - incorrect order in After of /lib/systemd/system/nginx.service

[Perlover]

Hello,

I know what the problem is.

The problem is that nginx starts before all network interfaces are upped 
up. I looked through all nginx unit files (nginx-common debian package) 
and found that all versions, including Ubuntu 22.04, have incorrect 
After & Wants.

All versions from the package specify After=network.target, but if you 
study this network.target, it does not guarantee that the entire network 
on the device is already configured. It is correct to use 
network-online.target. Moreover, it is also recommended by the nginx 
developers themselves:

https://www.nginx.com/resources/wiki/start/topics/examples/systemd/

As a temporary solution, I recommend doing so until it is fixed in the 
package nginx-common itself:

$ sudo systemctl edit nginx.service

To insert there:

[Unit]
After=syslog.target network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target
