Hello, on my server I have several IP-Addresses and for some of them I want to use Nginx to server port 80. I want to host several different domains. Let’s say [A.org](http://A.org) and [B.org](http://B.org) to IP-Address 1.1.1.1:80 and [C.org](http://C.org) to IP-Address 1.1.1.2:80, while 1.1.1.3:80 shall not be used by Nginx. Shall I configure Nginx something like server { listen 1.1.1.1; server\_name [A.org](http://A.org) [B.org](http://B.org); if ($host ~ “[A.org](http://A.org)”) {root /A; … break;} if ($host ~ “[B.org](http://B.org)”) {root /B;… break;} } server { listen 1.1.1.2; server\_name [C.org](http://C.org); } or is there a way to configure three different server{}s? server { server\_name [A.org](http://A.org); } server { server\_name [B.org](http://B.org); } server { server\_name [C.org](http://C.org); listen 1.1.1.2; } In the former form, I cannot use directly “root /A;” in if (). In the latter form, I cannot use for [A.org](http://A.org) and [B.org](http://B.org) listen 1.1.1.1, as Nginx says it cannot bind twice IP1.1.1.1 (it can bind to it for A, but since the socket is already occupied, it cannot bind for for [B.org](http://B.org)}. Moreover, as the Nginx module documentation is available both trough [wiki.nginx.org](http://wiki.nginx.org) ([wiki.nginx.org/HttpCoreModule](http://wiki.nginx.org/HttpCoreModule)) and [nginx documentation](http://www.nginx.org/en/docs/), I would like to ask which is the reference documentation (and what is the point to have the documentation on two different places – e.g. why isn’t the wiki enough). nginx version: nginx/1.0.15 TLS SNI support enabled configure arguments: --pid-path=/var/run/nginx.pid –conf-path=/etc/nginx/core.conf –error-log-path=/var/log/nginx/nginx.log --user=wwwrun --group=nogroup –with-ipv6 --without-poll\_module --without-select\_module –with-file-aio --with-http\_ssl\_module --with-http\_addition\_module –with-http\_xslt\_module --with-http\_image\_filter\_module –with-http\_sub\_module --with-http\_dav\_module --with-http\_flv\_module –with-http\_mp4\_module --with-http\_gzip\_static\_module –with-http\_random\_index\_module --with-http\_degradation\_module –with-http\_stub\_status\_module --http-log-path=/var/log/nginx –with-pcre --prefix=/usr --with-cc-opt=‘-O3 -march=native -Wl,–hash-style=gnu -Wl,-O1 -flto -Wl,-z,relro’ –with-ld-opt=‘-L/usr/lib64 -L/lib64’ --without-http\_ssi\_module –without-http\_uwsgi\_module --without-http\_scgi\_module –without-http\_upstream\_ip\_hash\_module –without-http\_split\_clients\_module --without-http\_empty\_gif\_module Thanks in advance for your help Дилян ---

The assertion that you cannot use the same IP twice is wrong, and probably the root of your misunderstanding. This _is_ legitimate configuration: * * * http { server { listen 1.1.1.1:80; server\_name [A.org](http://A.org); root /srv/A.org/public; } server { listen 1.1.1.1:80; server\_name [B.org](http://B.org); root /srv/B.org/public; } ## server { listen 1.1.1.2:80; server\_name [C.org](http://C.org); root /srv/C.org/public; } } There are more concise ways of expressing this setup, especially if you’re dealing with significant numbers of domains, but this is pretty unambiguous. ## Jonathan Jonathan M.

The right place is [nginx documentation](http://www.nginx.org/en/docs/) Until this year the only English documentation was in wiki, but the wiki contains errors and inaccurancies. – Igor S.
