In this guide I am going to go
over install nginx and getting it to work with python
One good resource I found on
how to do this is at http://perlmaven.com/deploying-pyton-with-uwsgi-on-ubuntu-13-10
[1] another is https://uwsgi.readthedocs.org/en/latest/tutorials/Django_and_nginx.html
[2] a third good blog
post is http://zacharyvoase.com/2010/03/05/django-uwsgi-nginx/ [3]
Install uwsgi
A good place I
got some notes from
|
> sudo
apt-get update
> sudo apt-get install uwsgi
> sudo apt-get install uwsgi-plugin-python
|
Now for a test, create a directory to put a test python file
|
> cd
> mkdir py-test
> cd py-test
> vi test.py
|
And put the following in it (this code is from http://perlmaven.com/deploying-pyton-with-uwsgi-on-ubuntu-13-10 )
|
def application(env,
start_response):
start_response('200 OK',
[('Content-Type','text/html')])
return "Hello World From
Python"
|
Then run it via uwsgi
|
> uwsgi
--http-socket :9090 --plugin python --wsgi-file test.py
|
It worked
Now stop the running program by hitting ctrl+c
Install nginx
Run the following commands
|
> sudo apt-get install nginx
|
Update nginx
I am going to place my website in a directory I am going to make
/www I also made a /www/logs folder to put site logs in
|
> sudo mkdir -p /www/main-site
> sudo mkdir -p /www/logs
|
Create a simple index.html file there for testing
|
> sudo vi /www/main-site/index.html
|
Put the following in the file
|
<html>
<body>
<h1>Test</h1>
</body>
</html>
|
And open http://192.168.0.186/ (in my case it is running
on 192.168.0.186… change this to match your server ip)
Now update /etc/nginx/nginx.conf
|
> sudo vi /etc/nginx/nginx.conf
|
Edit the document to the following (my server happens to
be running on ip address 192.168.0.186)
|
user www-data;
worker_processes 4;
pid /var/run/nginx.pid;
error_log
/var/log/nginx/error.log;
events {
worker_connections 1024;
use epoll;
multi_accept on;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
server {
listen 80;
keepalive_timeout 70;
server_name 192.168.0.186;
#Logs
access_log
/www/logs/main-site-access.log;
error_log /www/logs/main-site-error.log;
# doc root
root /www/main-site;
location ~ \.py$ {
uwsgi_pass 127.0.0.1:9000;
uwsgi_param QUERY_STRING $query_string;
uwsgi_param REQUEST_METHOD $request_method;
uwsgi_param CONTENT_TYPE $content_type;
uwsgi_param CONTENT_LENGTH $content_length;
uwsgi_param REQUEST_URI $request_uri;
uwsgi_param PATH_INFO $document_uri;
uwsgi_param DOCUMENT_ROOT $document_root;
uwsgi_param SERVER_PROTOCOL $server_protocol;
uwsgi_param HTTPS $https if_not_empty;
uwsgi_param REMOTE_ADDR $remote_addr;
uwsgi_param REMOTE_PORT $remote_port;
uwsgi_param SERVER_PORT $server_port;
uwsgi_param SERVER_NAME $server_name;
include uwsgi_params;
}
}
}
|
This will feed all files that end in ".py" to
127.0.0.1:9000
Restart nginx
|
> sudo /etc/init.d/nginx restart
|
Uwsgi and ini file
I had a few issues trying to even get this to work a little I did
get some information on an issue I was having at http://stackoverflow.com/questions/18501373/flask-nginx-uwsgi-python-application-not-found [4]
It helped me get past this error.
uWSGI Error
Python
application not found
Create a uwsgi ini file.
|
> cd
> vi uwsgi.ini
|
And place the following in it
|
[uwsgi]
chdir = /www/main-site
socket = 127.0.0.1:9000
master = true
workers = 4
plugin = python
pp = /www/main-site
module = test
|
Create the python program
|
> cd
/www/main-site/
> vi test.py
|
And put the following in it (this code is from http://perlmaven.com/deploying-pyton-with-uwsgi-on-ubuntu-13-10 )
|
def application(env,
start_response):
start_response('200 OK',
[('Content-Type','text/html')])
return "Hello World From
Python"
|
Now run the uwsgi by hand
|
> cd
> sudo uwsgi --ini uwsgi.ini
|
Success !! kinda….
This set up is enough to do a test I currently need to do but it
is not complete at all
One of the key problems I have is with the ini file
|
[uwsgi]
chdir = /www/main-site
socket = 127.0.0.1:9000
master = true
workers = 4
plugin = python
pp = /www/main-site
module = test
|
They pp is the python path and the module is the actual
program
So pp = /www/main-site and module = test
Together it says to run /www/main-site/test.py
I set up nginx to forward all *.py files to the uwsgi server
running on port 9000. Then the uwsgi
only opens /www/main-site/test.py
As an example f I open the url http://192.168.0.186/test/wrong/bob.py
I get the same site
Get it working with different .py files
I found a way to get it working using the suggestions at
Warning!!
THIS IS NOT A GOOD WAY TO
RUN A SERVER, but it works. THIS IS NOT
SOMETHING TO PUT INTO A REAL ENVIRONMENT.
Edit nginx.conf
|
> sudo vi /etc/nginx/nginx.conf
|
Edit the document to the following (my server happens to
be running on ip address 192.168.0.186)
|
user www-data;
worker_processes 4;
pid
/var/run/nginx.pid;
error_log
/var/log/nginx/error.log;
events {
worker_connections 1024;
use epoll;
multi_accept on;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
server {
listen 80;
keepalive_timeout 70;
server_name 192.168.0.186;
#Logs
access_log
/www/logs/main-site-access.log;
error_log /www/logs/main-site-error.log;
# doc root
root /www/main-site;
location ~ \.py$ {
include uwsgi_params;
uwsgi_param UWSGI_FILE
$request_filename;
uwsgi_param
UWSGI_TOUCH_RELOAD $request_filename;
uwsgi_param SCRIPT_NAME $uri;
if (-f $request_filename) {
uwsgi_pass
127.0.0.1:9000;
}
}
}
}
|
Restart nginx
|
> sudo /etc/init.d/nginx restart
|
Run uwsgi from the command with the following command
|
> sudo uwsgi -s :9000 -M -i --processes 4 --threads
2 --plugins python
|
And if you try to open http://192.168.0.186/nothere/doesnotexist.py
You get
Create a second python program
Now to test it make another python program in a subdirectory
|
> sudo mkdir -p /www/main-site/sub-dir/test
> sudo vi /www/main-site/sub-dir/test/test-2.py
|
Put the following in the program
|
def application(env,
start_response):
start_response('200 OK',
[('Content-Type','text/html')])
return "This is a test from the
second python program"
|
And you should see
That works J I apologize
that it is not a solution for a live environment but maybe it will help
someone.
If anyone has a better way to do this or knows a more
complete way please feel free to comment.
