YunoHost DynDNS Server
======================
**Note: Tested on Debian wheezy (should work on Ubuntu)**
### Setup
```bash
python3 -m venv venv
source venv/bin/activate
pip3 install -r requirements.txt
``` ```
git clone https://github.com/YunoHost/dynette
### Dev
```bash
FLASK_APP=app.py flask run
``` ```
### Production Web subscribe server deployment
-------------------------------
- You should also install bind9
- Include `/etc/bind/named.conf.local` in `/etc/bind/named.conf`
- Install the following services
##### `dynette.service`
``` ```
# Systemd config apt-get install postgresql ruby thin libpq-dev bundler apache2
[Unit]
Description=Dynette gunicorn daemon
After=network.target
[Service]
PIDFile=/run/gunicorn/dynette-pid
User=dynette
Group=dynette
WorkingDirectory=/var/www/dynette
ExecStart=/var/www/dynette/venv/bin/gunicorn -c /var/www/dynette/gunicorn.py wsgi:app
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
``` ```
##### `dynette-regen-named-conf.service` In dynette repository:
``` ```
[Unit] bundle install
Description=Dynette named.conf regen
After=network.target
StartLimitIntervalSec=10
StartLimitBurst=5
[Service]
Type=oneshot
WorkingDirectory=/var/www/dynette
ExecStart=/var/www/dynette/venv/bin/python3 /var/www/dynette/regen_named_conf.py
User=root
Group=root
[Install]
WantedBy=multi-user.target
``` ```
##### `dynette-regen-named-conf.path` Thin configuration:
``` ```
[Path] thin config -C /etc/thin1.9.1/dynette.yml -c /path/to/dynette/ --servers 3 -p 5000 -e production
Unit=dynette-regen-named-conf.service
PathChanged=/var/dynette/db/
[Install]
WantedBy=multi-user.target
``` ```
##### NGINX conf snippet Apache configuration:
``` ```
location / { vim /etc/apache2/sites-available/dynette
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_redirect off;
proxy_pass http://unix:/var/www/dynette/sock;
proxy_read_timeout 210s;
}
``` ```
### If we ever decide to add another base domain Paste & change server name in below configuration:
We should initialize `/var/lib/bind/BASE_DOMAIN.db` (replace `BASE_DOMAIN` with e.g. nohost.me) with:
```text
$ORIGIN .
$TTL 10 ; 10 seconds
BASE_DOMAIN IN SOA ns0.yunohost.org. hostmaster.yunohost.org. (
1006380 ; serial
10800 ; refresh (3 hours)
3600 ; retry (1 hour)
604800 ; expire (1 week)
10 ; minimum (10 seconds)
)
$TTL 3600 ; 1 hour
NS ns0.yunohost.org.
NS ns1.yunohost.org.
$ORIGIN BASE_DOMAIN.
``` ```
<VirtualHost *:80>
ServerName dyndns.yunohost.org
RewriteEngine On
<Proxy balancer://thinservers>
BalancerMember http://127.0.0.1:5000
BalancerMember http://127.0.0.1:5001
BalancerMember http://127.0.0.1:5002
</Proxy>
# Redirect all non-static requests to thin
RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ balancer://thinservers%{REQUEST_URI} [P,QSA,L]
ProxyPass / balancer://thinservers/
ProxyPassReverse / balancer://thinservers/
ProxyPreserveHost on
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
# Custom log file locations
ErrorLog /var/log/apache2/dynette-error.log
CustomLog /var/log/apache2/dynette-access.log combined
</VirtualHost>
```
PostgreSQL configuration:
```
# adduser dynette
# passwd dynette
# su - postgres
$ psql template1
template1=# CREATE USER dynette WITH PASSWORD 'myPassword';
template1=# CREATE DATABASE dynette;
template1=# GRANT ALL PRIVILEGES ON DATABASE dynette to dynette;
template1=# \q
```
Edit dynette.rb, change PostgreSQL password and domains handled, line 11-12:
```
DataMapper.setup(:default, ENV['DATABASE_URL'] || "postgres://dynette:myPassword@localhost/dynette")
DOMAINS = ["nohost.me", "noho.st"]
```
Enable apache2 sites & modules:
```
a2enmod proxy
a2enmod rewrite
a2ensite dynette
service thin start
service apache2 restart
```
DNS configuration
-----------------
```
apt-get install bind9 python
```
Edit dynette.cron.py and change settings:
```
subs_urls = ['http://dyndns.yunohost.org']
ns1 = 'dynhost.yunohost.org'
ns2 = 'hostmaster.yunohost.org'
```
Create dynette log file
```
touch /var/log/dynette.log
```
Enable cronjob for dynette (crontab -e)
```
* * * * * /path/to/dynette/dynette.cron.py >> /var/log/dynette.log 2>&1
```
Troobleshooting
---------------
If you run into troubles running the DNS server, try to check permissions on /var/lib/bind and check if bind listens on 0.0.0.0 (in /etc/bind/bind.conf.options)
