Web2py with ngix

[J Boggy]

Web2py with ngix start work well.
But when i start uwsgi
it show uwsgi.service not found error.
If i need to create service i don't know how to create.
I follow this way

On my working machine (Debian 8 Testing (systemd), nginx)

I have installed with the script

https://github.com/web2py/web2py/blob/master/scripts/setup-web2py-nginx-uwsgi-ubuntu.sh

but there was some problem or some missing code which I have found somewhere here in user group.

I am not sure if last version of the script at github.com/web2py/web2py works,

but maybe my files could help you:

-rw-r--r-- root root /etc/init/uwsgi-emperor.conf

description "uWSGI Emperor"

start on runlevel [2345]

stop on runlevel [06]

#remove the comments in the next section to enable static file compression for the welcome app

#in that case, turn on gzip_static on; on /etc/nginx/nginx.conf

#    python /home/www-data/web2py/web2py.py -S welcome -R scripts/zip_static_files.py

#    chown -R www-data:www-data /home/www-data/web2py/*

Previous works and I made no my own changes inside. It is just from the Web2py nginx/ubuntu script and from some post in this user group.

I control the service so:

systemctl start emperor.uwsgi     # stop,restart,status,...

And this is the third file:

-rw-r--r-- root root /etc/systemd/system/emperor.uwsgi.service

Description = uWSGI Emperor

After = syslog.target

[Service]

ExecStart = /usr/local/bin/uwsgi --ini /etc/uwsgi/web2py.ini

[Install]

... I hope it is complete now...

[Mirek Zvolský]

And here is the version of script that I have used (I hope so) to install on my machine.

So if you decide use the installation script setup-web2py-nginx-uwsgi-ubuntu.sh

maybe you could try the version from current trunk github.com/web2py/web2py

and as second one you can try this version:

#!/bin/bash

echo 'setup-web2py-nginx-uwsgi-ubuntu-precise.sh'

echo 'Requires Ubuntu > 12.04 or Debian >= 8 and installs Nginx + uWSGI + Web2py'

# Check if user has root privileges

if [[ $EUID -ne 0 ]]; then

   echo "You must run the script as root or using sudo"

   exit 1

fi

# parse command line arguments

nopassword=0

nocertificate=0

while [ "$#" -gt 0 ]; do

  case "$1" in

    --no-password) nopassword=1; shift 1;;

    --no-certificate) nocertificate=1; shift 1;;

  esac

done

# Get Web2py Admin Password

if [ "$nopassword" -eq 0 ]

then

  echo -e "Web2py Admin Password: \c "

  read  PW

fi

you can stop uwsgi and nginx with

and start it with

  sudo systemctl start nginx

  sudo systemctl start emperor.uwsgi

One thing more....

In my opinion the service is controlled without ".service" in name.

systemctl start emperor.uwsgi    (if /etc/systemd/system/emperor.uwsgi.service used)

systemctl start uwsgi    (if the name is /etc/systemd/system/uwsgi.service as (maybe) in your 'digitalocean' article)

Hello Mirek,

Your contribution is pretty much appreciate, but it would make more sens that you submit your improvements as a PR over github and then point other users over you fork or the PR pending acceptation our your commit once PR accepted...

Thanks for your help

Hi Richard.

I'm beginner with Linux (upgrade from Windows to Linux was one of best steps in my professional life!).

However at this time it is for me not good idea to write bash scripts for some complex product.

In fact I made PR in this case (when I have added something from other post in this user group into the Web2py nginx/ubuntu script).

It was not accepted, but maybe the team has implemented/reimplemented the changes into the framework full or partially.

But I am not sure about this (and haven't time to test it).

This is the reason why I have written:

  - give first opportunity to the script from framework (github web2py/web2py),

  - if it fails, then (maybe) my version could work.

No problem...

You maybe could post diff of your change, it would greatly help to understand what you change.

Maybe it get rejected because it was applying for Debian only?

Anyway thanks for your contribution, I just want to point you in the rigth direction to improve chance your work didn't get lost on the list as it happen sometimes.

:)

I just posted an issue with uwsgi and setup-web2py-nginx-uwsgi-ubuntu.sh to the mailing list ( https://groups.google.com/forum/#!topic/web2py/U_GTzcdXdKE )
This might possible be related..

Thanks, Richard.

I have my Web2py fork and I will send PR in the future if I will know, what to improve.

I have just now compared current Web2py script --vs-- version of script I have used (it was in my fork, but I have reinstalled without it) --vs-- configuration files on my well working server,

and I see all of them have all 3 configuration files (/etc/init/.., /etc/uwsgi/.., /etc/systemd/system/..)

and these files are identical.

So I think the installation with the nginx/ubuntu script (from trunk) will work.

There was some problem in OLD history (2015?):

/etc/uwsgi/web2py.ini was missing (web2py 2.13.4) + there was a missing code in /etc/systemd/system/emperor.uwsgi.service

see this thread: https://groups.google.com/forum/#!starred/web2py/ZM9IIEjtHSI

I think today is all ok with current stable and with trunk too.

[Richard Vézina]

Yes, there were a lot of changes related to systemd as the way to init deamon as change a lot... Despite all the criticism about systemd, I found it a lot more simpler to write init (just a few lines of code) compare to the old /etc/init.d/ bash script file...

Regards

Richard

thz i have been solved.
Now other error is i cannot import some module althougn i have been installed and tested on python. But in web2py controller i can't import module

[Richard Vézina]

Hello Boggy,

Are you installing web2py over your own server or or cloud service?

If it your own server can you details what you have done so far, are you trying to install web2py by hand or you use one the scripts provided with web2py?

Richard
