Nginx: Configure and Install With IPv6 Networking Support

How do I configure IPv6 networking under nginx? How do I assign and use an IPv6 address under nginx web server? How do I enable IPv6 Support in nginx?

You can easily configure IPv6 under nginx as follows. First, make sure IPv6 networking is working properly. See IPv6 CentOS / RHEL, FreeBSD, Debian / Ubuntu Linux, and Novell Suse/OpenSUSE Linux network configuration for more info.

Compile Nginx With IPv6 Support

You need to pass the --with-ipv6 option to configure command. Type the following command to compile it, enter:
# cd /path/to/nginx-src-code/ # ./configure --without-http_autoindex_module --without-http_userid_module \ --without-http_auth_basic_module --without-http_geo_module \ --without-http_fastcgi_module --without-http_empty_gif_module \ --with-poll_module --with-http_stub_status_module \ --with-http_ssl_module --with-ipv6 # make install
Verify the same with the following command:
# /usr/local/nginx/sbin/nginx -V
Sample outputs:

nginx version: nginx/0.8.46
built by gcc 4.1.2 20080704 (Red Hat 4.1.2-48)
TLS SNI support disabled
configure arguments: --without-http_autoindex_module --without-http_userid_module --without-http_auth_basic_module --without-http_geo_module --without-http_fastcgi_module --without-http_empty_gif_module --with-poll_module --with-http_stub_status_module --with-http_ssl_module --with-ipv6

Make sure you pass options as per your setup.

Edit Configuration File

Edit /usr/local/nginx/conf/nginx.conf, enter:
# vi /usr/local/nginx/conf/nginx.conf
Make sure listen directive is updated as follows (this must be placed between server { ... } ) :

 
# listen to all IPv4 and IPv6 interfaces:
# ipv4
listen :80;
# ipv6
listen [::]:80;

Reload and restart nginx configuration, enter:
# /usr/local/nginx/sbin/nginx -t && /usr/local/nginx/sbin/nginx -s reload

How Do I Listen Only On 2607:f0d0:1002:59::2?

Edit config file as follows:
listen listen [2607:f0d0:1002:59::2]:80;

How Do I Verify IPv6 and IPv4 Both Are Working?

Use the netstat command to verify ip binding:
# netstat -tulpna | grep nginx
Sample outputs:

tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      33094/nginx
tcp        0      0 0.0.0.0:443                 0.0.0.0:*                   LISTEN      33094/nginx
tcp        0      0 :::80                       :::*                        LISTEN      33094/nginx

The last line indicates that IPv6 and first two line indicate HTTP and HTTPS connection for IPv4. You can also use the wget command or a web browser to verify the same:
$ wget http://[2607:f0d0:1002:59::2]/
