RestDNS README

RestDNS is a REST API used to store and manage your DNS zones. Also look at restdns-cli and restdns-bind

Setup

RestDNS is packaged for the Debian Wheezy distro, but since its a standard Django application, it should be easy to install it on any other distro.

Install the RestDNS package

Add these lines in your /etc/apt/source.list file:

deb http://debian.tecknet.org/debian wheezy tecknet
deb-src http://debian.tecknet.org/debian wheezy tecknet

Add the Tecknet repositories key in your keyring:

# wget http://debian.tecknet.org/debian/public.key -O - | apt-key add -

Update and install the restdns package:

# aptitude update
# aptitude install restdns

The installation procedure will configure the database (SQLite by default) in the /var/lib/restdns/ directory.

Configure Gunicorn

The next step is to configure gunicorn to serve the restdns application, in the /etc/gunicorn.d/ directory, copy the restdns.example file to restdns:

# cd /etc/gunicorn.d
# cp restdns.example restdns

You can customize the file to add or change Gunicorn options such as the http listening port (by default 9001) or the number of workers to start.

Restart the Gunicorn daemon to start RestDNS:

# service gunicorn restart

Configure the web server

The last thing to do is to configure a web server to reverse proxify the RestDNS application. Here is an example for nginx:

# cat /etc/nginx/site-enabled/restdns
server {
    location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass http://127.0.0.1:9001/;
        proxy_redirect default;
    }
}
