Changes with nginx 0.7.44:
....
*) Bugfix: if there is the single server for given address:port pair,
then captures in regular expressions in a "server_name" directive
did not work.
....
Adding another server listening on the same socket should resolve
the issue, though I would recommend to upgrade. 0.6.* branch is
legacy and not supported, and you are using an old version from
this branch.
Additionally, it's *really bad* idea to use enumerated captures in
server_name. Things may be screwed up easily - it's enough to add
another regexp to config (e.g. regexp location) to break anything.
There are two possible safe aproaches:
1. Use named captures as available in nginx 0.8.25+.
server {
server_name ~^(P<name>.+)\.mydomain\.com$;
root /home/$name/public_html;
...
}
See http://nginx.org/en/docs/http/server_names.html for details.
2. For old versions - use server-level if, i.e.
server {
server_name *.mydomain.com;
set $name "";
if ($host ~ "^(.+)\.mydomain\.com$") {
set $name $1;
}
root /home/$name/public_html;
...
}
