nginx – basics

Posted on by treaclepumpkin

This is a quick aid based on the Raspberry Pi documentation.

Some basic commands are:

sudo nginx -s reload
sudo nano /etc/nginx/nginx.conf
systemctl status nginx.service

Cannot synchronise MLAT with Piaware?

Posted on by treaclepumpkin

Possibly an issue with Pi firmware of 4.9.x, find out your version by using this command

uname -a

If so then issue these commands, the first installs the firmware updater the second the 4.4.50 version of the firmware.

sudo apt-get install rpi-update
sudo rpi-update 52241088c1da59a359110d39c1875cda56496764

If you can’t install the firmware because you have a “custom” kernel then you’ll have to get the latest version of Raspbian and install that, then run the above two commands.

Reducing wear on your sd-card

Posted on by treaclepumpkin

One way to increase the lifespan, and presumably, reliability of the sd-card, currently being hammered, in your Pi is to put some of the temporary files into memory.

Add the following to your /etc/fstab

tmpfs /var/log tmpfs nodev,nosuid,size=50M 0 0

If the size isn’t specified then half of the machine’s memory is used.
nodev and nosuid are security options, the suggestion is that these only need setting for public facing machines.

 

8-Jan-2018: If you’re using the lighttpd web server then be aware that it stores files in /var/log, and it doesn’t like them being removed. This will cause the server to fail to start.
