When I use the config
server {
server_name ~^(www\.)?(?<domain>.+)$;
return 200 "domain is $domain\n";
}
I get the message
nginx: [emerg] pcre_compile() failed: unrecognized character
after (?< in "^(www\.)?(?<domain>.+)$" at "domain>.+)$" in
/usr/local/nginx/conf/nginx.conf
because my PCRE version does not recognise that syntax.
The page at http://nginx.org/en/docs/http/server_names.html does say:
"""
The PCRE library supports named captures using the following syntax:
?<name> Perl 5.10 compatible syntax, supported since PCRE-7.0
?'name' Perl 5.10 compatible syntax, supported since PCRE-7.0
?P<name> Python compatible syntax, supported since PCRE-4.0
If nginx fails to start and displays the error message:
pcre_compile() failed: unrecognized character after (?< in ...
this means that the PCRE library is old and the syntax “?P<name>” should be
tried instead.
"""
When I change the main line (by adding an extra P) to be
server_name ~^(www\.)?(?P<domain>.+)$;
then it all seems to work for me:
$ curl -H Host:www.example.com http://localhost/
domain is example.com
$ curl -H Host:example.com http://localhost/
domain is example.com
$ curl -H Host:no.example.com http://localhost/
domain is no.example.com
> servername: www.example.com -> $domain should be example.com
It works for me. What output do you get instead of what you want to get?
