Trouble installing reef-pi

eb_reef · Mar 26, 2018

I am having trouble installing reef-pi. I have an older pi Model B Rev 2.0.

I follow these instructions https://reef-pi.github.io/general-guides/install/ and everything appears to work fine but I cannot get to the web UI. Also there is no web server running that I can find nor anything listening to a port other than ssh. Is there something else I am supposed to do in order to get the web interface up?

Edit: I installed the latest reef-pi for pi3 version pH sub-system

do you have ssh access to the pi, if so, can you try these and let us know whats the output of this command:

Code:

sudo systemctl status reef-pi.service

reef-pi is not running on your Raspberry Pi. I think you are running wrong binary, i.e. you are trying to run pi 3 binary on pi 2.
Can you run following commands:

Code:

file /usr/bin/reef-pi
uname -a

Also can you run this and share the output

Code:

readelf -A /usr/bin/reef-pi

Ranjib · Mar 27, 2018

I am pretty sure this is wrong binary issue, pi model B is similar to pi zero (processor wise), and pi 2/3 is a different processor. Try uninstalling existing reef-pi , and then install the pi-zero version of reef-pi.

I should probably document this in the installation guide,
sorry about the trouble.

eb_reef · Mar 27, 2018

Thanks changing to the pi-zero version fixed it

godspeed. Dont hesitate to ask question on the main reef-pi thread (there are lot more folks who can lend a hand , in that thread)

I am unable to run the UI. It appears the service is running properly, but when I try to run the UI, I get a .txt file back. What am I missing?

@Modell I think you should probably start a new thread in the DIY section and tag @Ranjib this thread looks old as it is from 2018. He is pretty good about replying quickly. Summarize what you have done and what’s not working.

Something else is wrong here. This is a php script, its not belong to reef-pi. reef-pi is built with different technology than what you are showing here. This is something else... i dont know exactly what it is.. but its written in php and not configured properly (hence its serving the raw php code instead of html/ui). Think what you have insteallled? the command `sudo lsof -i :80` should give you the pid of the process thats running this. ps should reveal which process it is from the pid.

Here’s my response to that command:

Not sure what's happening but try reformatting your SD card and follow these instructions to install, hope it helps.

hmm.. reef-pi is listening to that port. Im not sure then why the webpage is showing PHP code :-( . Make sure you are using the same IP as the PI ,

Also, please start a new thread, it looks like we are resurrecting and older/unrelated thread :-/

Modell · Dec 30, 2020

Thank you. I have managed to get it running. Temp sensor works. Now I need to figure out how to get it to control my Sainsmart relay board. I’ll start a new thread when I get frustrated enough with that. Thanks Again!
