Need Help for the webserver

[KSuondProject]

Hi all! I'm tryng to start up the server. Where I read "your domain" in the instruction, I write local Ip (192.168.x.x) right? Or the public IP? Sorry but I don't know how to continue because when I write the local IP of the raspberry in the browser I see only the standard "NGINX presentation page" and nothing else. If I write my public IP address I see my modem router configuration page. Can someone help me?

[duxenmx]

It should be the ip of your pi, did you followed the tutorial for the webserver in the wiki?

[KSuondProject]

Yes, I've followed the wiki instruction. In every form that required the "your address" I've putted the IP of my raspberry. But when I open the browser page I see only the nginx startup page and not the webserver. In this moment after a reboot I see a 502 bad gatway error. There's some command that I can try to see what I miss? The systemctl status command says me that the serice is active with no error.

Mmm, gunicorn seems to be working fine, try again the step 5 from the tutorial please

[KSuondProject]

Mmm, gunicorn seems to be working fine, try again the step 5 from the tutorial please

Just do that but nothing, is always showing this page when I call the Raspberry's IP in the browser:

https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Fcdn.deliciousbrains.com%2Fcontent%2Fuploads%2F2015%2F03%2FImage-1-Nginx.jpeg&f=1&nofb=1

This is my nginx file:

server {
listen 80;
server_name localhost www.192.168.1.126;

location / {
include proxy_params;
proxy_pass http://unix:/home/pi/e_paper_dashboard/www/Dashweb.sock;
}
}

Another noob question, the "Dashweb.sock" is a file? I haven't found it in that folder.

Also the settings.html located in the /home/pi/e_paper_dashboard/www/templates folder have 192.168.1.126 IP

[duxenmx]

yeah its a file in the www folder, it creates when you start and enable the service,

in your nginx file remove the "www." and restart nginx

[KSuondProject]

I've removed the "www." but now the page response a "502" Bad gateway. Any ideas? Why I don't have the "Dashweb.sock" file?

Thank you again for the support.

Why have a permission denied? There's wrong with my router? Some firewall problem?

[duxenmx]

mmmm, what about the ufw did you ran the commands to allow nginx?

sudo ufw delete allow 5000
sudo ufw allow 'Nginx Full'

can you also show me what you have in your service file? (code)

[KSuondProject]

Here's all the result:

[duxenmx]

mmmm, the sock file is there, how are you seeing you files?, via winscp?, ls?

try opening the port 80 as well sudo ufw allow 80

and reload the web browser if nothing comes up restart nginx again after this add

[KSuondProject]

I've opened a ftp connection with linux mint file explorer and I don't see that file.

I've opened the 80 standard http port and restart the gninx service as you say me but nothing happen:

2020/12/27 11:43:16 [crit] 1041#1041: *1 connect() to unix:/home/pi/e_paper_dashboard/www/Dashweb.sock failed (13: Permission denied) while connecting to upstream, client: 192.168.1.26, server: localhost, request: "GET / HTTP/1.1", upstream: "http://unix:/home/pi/e_paper_dashboard/www/Dashweb.sock:/", host: "192.168.1.126"

[duxenmx]

try renaming your service file to Dashweb.service instead of myproject.service and reload it.

sorry if it seems like shooting in the dark, havent gotten errors like these ones, so trying what I think it might be

[KSuondProject]

Is it correct?

I've restarted the gninx service, but always Bad Gateway.

[duxenmx]

I was looking around and from the error it seems that its permissions (as it says), the file does exist, try refreshing your ftp connection,(it does happens to me when using winscp and they I refresh the explorer and it shows), on the terminal in the www folder do sudo chmod 0777 Dashweb.sock

[KSuondProject]

pi@raspberrypi:~/e_paper_dashboard/www $ sudo chmod 0777 Dashweb.sock
chmod: cannot access 'Dashweb.sock': No such file or directory

I really don't know how is possible. I can copy this file from somewhere?

[KSuondProject]

Sorry I have accidentally close the issue by pressing "close" form from app.

[duxenmx]

in the service file try this

remove the -m from

ExecStart=/home/pi/e_paper_dashboard/www/dashenv/bin/gunicorn --workers 3 --bind unix:Dashweb.sock -m 007 wsgi:app

save and restart the service sudo systemctl daemon-reload sudo systemctl restart Dashweb

[KSuondProject]

I've do all of that you write up, nothing change. No .sock file created and always 502 Bad Gateway. Maybe something wrong with the pip modules?

Hey, sorry, it was a little late for me yesterday and even right now,,,(I'm on central time, though in vacation which is why I'm still up, heh,) so what is tail -f /var/log/nginx/error.log

throwing you this time?

[duxenmx]

someone else use to have some problem of permissions, what we tried with him was this -remove the project from the pi -create your own empty folders for the e_paper_dashboard and an empty folder for www inside of it -move the contents of the www folder from the project to the new empty folder, do the same with the other folders and files inside the e_paper_dashboard folder level

absolutely no problem, indeed thank you so much for your help! Here's the log, the same of yesterday:

Ok, I try it right now! Let you know asap.

[KSuondProject]

But the dashboard.sock will created automatically when the webserver works? Because I don't have this file.

[duxenmx]

Once you move the files you'll have to reload the service after that check if the sock file it's created in the folder

[KSuondProject]

Ok, the copy of files is near to the end. I'll write soon!

the service file with the correct directorys:

[duxenmx]

while you are in your virtual environment in the www folder try

gunicorn --bind 0.0.0.0:5000 wsgi:app

[KSuondProject]

pi@raspberrypi:~/dashboard/www $ source dashenv/bin/activate
(dashenv) pi@raspberrypi:~/dashboard/www $ gunicorn --bind 0.0.0.0:5000 wsgi:app
-bash: /home/pi/dashboard/www/dashenv/bin/gunicorn: /home/pi/e_paper_dashboard/www/dashenv/bin/python3.7: bad interpreter: No such file or directory
(dashenv) pi@raspberrypi:~/dashboard/www $ 

[duxenmx]

reinstall the packages while in the venv

pip install gunicorn flask wheel

[KSuondProject]

now after the gunicorn command the result is:

(dashenv) pi@raspberrypi:~/dashboard/www $ gunicorn --bind 0.0.0.0:5000 wsgi:app

the browser:

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

[duxenmx]

is there a "credentials" folder in your dashboard folder?, if not, can you create and run gunicorn again

[KSuondProject]

OMG!!! Finally I see the webserver page!!!

[KSuondProject]

But how I can made it works in the "normal" conditions?

[duxenmx]

wohooo!, with the service and nginx finally working?

[KSuondProject]

Unfortunately not, with a standard call of my IP I have always the "Bad Gateway" error.

[KSuondProject]

in the jurnactl command i see:

[KSuondProject]

Is this the problem?

Dec 28 13:12:38 raspberrypi gunicorn[998]: ModuleNotFoundError: No module named '007'

[duxenmx]

can you try to put the -m before the 007 in the service file

[duxenmx]

and restart the service

[KSuondProject]

I've already done this correction, my file now is:

[Unit]
Description=Gunicorn `instance` to serve myproject
After=network.target

[Service]
User=pi
Group=www-data
WorkingDirectory=/home/pi/dashboard/www
Environment="PATH=/home/pi/dashboard/www/dashenv/bin"
ExecStart=/home/pi/dashboard/www/dashenv/bin/gunicorn --workers 3 --bind unix:dashweb.sock -m 007 wsgi:app

[Install]
WantedBy=multi-user.target

[duxenmx]

and it gave you that problem after adding the -m?

can you try once again to reload the service and the daemon sudo systemctl daemon-reload sudo systemctl restart Dashweb (your service name)

if its not working restart the pi to see it if loads the correct confs

[duxenmx]

I'm out for the today, but I'll be back later to help you with this

Have done all of this but nothing. The problem is alway the "dashweb.sock" file that dowesn't exist as you can see in the error.log of the nginx:

2020/12/28 13:42:08 [crit] 590#590: *1 connect() to unix:/home/pi/dashboard/www/Dashweb.sock failed (2: No such file or directory) while connecting to upstream,....

I'm out for the today, but I'll be back later to help you with this

Really really many thanks for your support! You're really the best!! :top:
