Hardware:

• Oregon Scientific WMR88
• Seagate Dockstar Freeagent

Software

• Uboot
• Debian Linux
• WeeWX

First of all login to the Dockstar as root and download the latest deb package of WeeWX:

~# wget http://weewx.com/downloads/weewx_3.6.2-1_all.deb

Next step install necessary dependencies and WeeWX:

~# apt-get install python-usb python-serial python-imaging python-cheetah python-configobj rsync
~# dpkg -i ./weewx_3.6.2-1_all.deb

The weewx generated web files are stored in /var/www/html/weewx on the dockstar. They need to be copied via rsync to an apache/nginx host (web-host) in /var/www/html/weewx. On the web host it would be appropriate not to use root account for copying files via rsync. So the target directory should be user www-data.

~# chgrp -R www-data /var/www/
~# chown -R www-data /var/www/

Also the user www-data needs a home dir and a shell.

~# vi /etc/passwd
............
www-data:x:33:33:www-data:/var/www:/bin/bash
............

The process weewx on the dockstar is running as root and needs to upload the generated weather pages cyclically to the web host. For having a password-less rsync the user root must generate a ssh key pair and the public key needs to be copied to the web host.

~# ssh-keygen -t rsa
~# ssh-copy-id www-data@web-host

Test access from weewx by

~# ssh www-data@web-host

And a shell must be opened without passwd.

On the dockstar the config files of weewx needs to be edited:

~# vi /etc/weewx/weewx.conf
............
[[RSYNC]]
        skin = Rsync
        server = web-host
        path = /var/www/html/weewx
        user = www-data
        delete = 1
............

After all restart weewx service:

~# systemctl restart weewx.service
