I've moved my server to a new provider and changed the OS within this task from
|
|
[Rocky Linux](https://rockylinux.org/) to [OpenBSD](https://www.openbsd.org/).
|
|
|
|
## Installation of WeeWX
|
|
|
|
The [Installation Guide](http://weewx.com/docs/setup.htm) is very useful and
|
|
you should follow its procedure.
|
|
|
|
I installed WeeWX into `/home/weewx`. I also created a new user named _weewx_.
|
|
|
|
```
|
|
weewx:*:999:999:WeeWX Daemon:/home/weewx:/sbin/nologin
|
|
```
|
|
|
|
Also install some prerequisites:
|
|
|
|
```
|
|
pkg_add py3-configobj py3-serial py3-pyusb py3-pip py3-cheetah py3-jplephem py3-pymysql
|
|
```
|
|
|
|
```console
|
|
$ python3 ./setup.py build
|
|
$ doas python3 ./setup.py install
|
|
```
|
|
|
|
Optionally install ephem:
|
|
|
|
```console
|
|
$ doas -u weewx pip install ephem
|
|
```
|
|
|
|
You may want to change owner of the installed files (in case you didn't create
|
|
the weewx user beforehand and used the root user for that before).
|
|
|
|
```console
|
|
# cd /home/weewx
|
|
# chown -R weewx:weewx .
|
|
# cd /var/www/weewx
|
|
# chown -R weewx:weewx .
|
|
```
|
|
|
|
### Finally installed python stuff
|
|
|
|
```console
|
|
# pkg_info | grep py3 | awk '{ print $1 }'
|
|
py3-chardet-5.1.0
|
|
py3-cheetah-3.2.6p3
|
|

|
|

|
|
py3-numpy-1.24.1
|
|
py3-pip-23.0.1
|
|
py3-pymysql-1.0.2p2
|
|

|
|

|
|

|
|

|

## Setting up the start script
|
|
|
|
I've put the following file into `/etc/rc.d/weewx`:
|
|
|
|
```sh
|
|
#!/bin/sh
|
|
# Start script for FreeBSD, contributed by user Fabian Abplanalp
|
|
# Put this script in /usr/local/etc/rc.d then adjust WEEWX_BIN and
|
|
# WEEWX_CFG values in /etc/defaults/weewx
|
|
# some small modifications by Dominic Reich “OE7DRT”
|
|
|
|
WEEWX_BIN="/home/weewx/bin/weewxd"
|
|
WEEWX_CFG="/home/weewx/weewx.conf"
|
|
#WEEWX_PID="/var/run/weewx/weewx.pid"
|
|
WEEWX_PID="/home/weewx/weewx.pid"
|
|
DOAS="/usr/bin/doas -u weewx"
|
|
|
|
# Read configuration variable file if it is present
|
|
#[ -r /etc/defaults/weewx ] && . /etc/defaults/weewx
|
|
[ -r /home/weewx/defaults ] && . /home/weewx/defaults
|
|
|
|
case "$1" in
|
|
"start")
|
|
echo "Starting weewx..."
|
|
${DOAS} ${WEEWX_BIN} ${WEEWX_CFG} --daemon --pidfile ${WEEWX_PID} &
|
|
#echo $! > ${WEEWX_PID}
|
|
echo "done"
|
|
;;
|
|
|
|
"stop")
|
|
echo "Stopping weewx..."
|
|
if [ -f ${WEEWX_PID} ] ; then
|
|
kill `cat ${WEEWX_PID}`
|
|
rm ${WEEWX_PID}
|
|
echo "done"
|
|
else
|
|
echo "not running?"
|
|
fi
|
|
;;
|
|
|
|
"restart")
|
|
echo "Restarting weewx..."
|
|
$0 stop
|
|
sleep 2
|
|
$0 start
|
|
;;
|
|
|
|
*)
|
|
echo "$0 [start|stop|restart]"
|
|
;;
|
|
|
|
esac
|
|
```
|
|
|
|
Add `weewx` to `pkg_scripts=` in `/etc/rc.conf.local` and start it with
|
|
|
|
```console
|
|
$ doas rcctl start weewx
|
|
```
|
|
|
|
## Status text for APRSWXNET (aprs.fi)
|
|
|
|
I do also send a status message which adds a nice link back to my weather
|
|
website on
|
|
[aprs.fi](https://aprs.fi/#!call=a%2FOE7DRT-13&timerange=3600&tail=3600).
|
|
|
|
This is basically done with a python script run by cron every hour.
|
|
|
|
```python
|
|
#!/usr/bin/env python3
|
|
|
|
"""sending aprs status packets for my weather station"""
|
|
|
|
import aprslib
|
|
|
|
|
|
def main():
|
|
"""main func"""
|
|
AIS = aprslib.IS("OE7DRT-13", passwd="*****", port=14580)
|
|
AIS.connect()
|
|
|
|
AIS.sendall("OE7DRT-13>APRS,TCPIP*:>Weatherpage: https://wx.oe7drt.com\r\n")
|
|
|
|
if __name__ == "__main__":
|
|
main()
|
|
```
|
|
|
|
```console
|
|
$ crontab -l
|
|
57 * * * * python3 /home/dominic/bin/aprs_sendstatus.py
|
|
```
