IMHO, this is a pcre version issue. Old versions do not support named
selections.

Could you please try to update your system pcre library or just
compile the latest lib version in nginx using --with-pcre=/path/to/
custom/pcre

It seems you have PCRE prior to 7.0, try:

  • server_name   ~^test\.(?<domain>.+)$;

  • server_name   ~^test\.(?P<domain>.+)$;

I have pcre-6.6 available on the machine.

I can confirm that’s working, and I’ve updated the wiki with this
information.

Thanks Igor!

The alternatvie syntax “?P<…>” can be used. It’s old enough.

nginx -t
