Installation of Uboot
Installation of Debian
Installation of 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
Configuration of WeeWX
Specify source and target directories
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 ............
Configure ssh to use rsync without passwd
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.
Configure weewx to use rsync to copy files to web host
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
