Prerequisites
- A FastyCloud server running up to date Arch Linux (see this article.)
- A running webserver, either Apache or Nginx
- Sudo access:
- Commands required to be ran as root are prefixed by
#
. The recommended way to run commands as root is to, as a regular user, prefix each of them withsudo
- Commands required to be ran as root are prefixed by
- Have a text editor installed, and be familiar with it, such as vi, vim, nano, emacs or a similar editor
Install Python 3.7 On Your Webserver
On Apache
Unfortunately, it is not supported to run both versions of Apache modules (for Python 2.x and 3.x) at the same time on the same Arch system, but this is rarely a problem.
To use Python 3.x:
# pacman -S mod_wsgi
Enable the Apache mod_wsgi
module by editing /etc/httpd/conf/httpd.conf
, and at the end of the list of LoadModule
commands, add the following:
LoadModule wsgi_module modules/mod_wsgi.so
On Nginx
To use Python 3.x:
# pacman -S uwsgi-plugin-python
Test Python
Within the appropriate directory, create test.py
with the following contents:
#-*- coding: utf-8 -*-
def wsgi_app(environment, start_response):
import sys
output = sys.version.encode('utf8')
status = '200 OK'
headers = [('Content-type', 'text/plain'),
('Content-Length', str(len(output)))]
start_response(status, headers)
yield output
application = wsgi_app
On Apache
Add to the end of /etc/httpd/conf/httpd.conf
, or if you are running multiple hosts, edit the appropriate configuration file, and add in the appropriate <VirtualHost>
block:
WSGIScriptAlias /wsgi_app /srv/http/test.py
Restart Apache:
# systemctl restart httpd
In a web browser, visit http://YOUR-SERVER-WEB-ADDRESS-OR-IP/wsgi_app
, and you will see a test page with the python and GCC versions.
Delete the test.py
test file you just created, and the WSGIScriptAlias
in your Apache configuration.
Restart Apache:
# systemctl restart httpd
On Nginx
Create the file /etc/uwsgi/wsgi_app.ini
with the following contents:
[uwsgi]
socket = /run/uwsgi/wsgi_app.sock
uid = http
gid = http
plugins = python
chdir = /usr/share/nginx/html/
wsgi-file=test.py
callable = application
Start uWSGI serving wsqi_app
:
# systemctl start uwsgi@wsgi_app
Allow Nginx to use uWSGI by editing /etc/nginx/nginx.conf
, and for every server block you want to test, add the following. Alternatively, if you are using virtual hosts, edit each host’s configuration file:
location ~ \wsgi_app {
root /usr/share/nginx/html/;
include uwsgi_params;
uwsgi_pass unix:/run/uwsgi/wsgi_app.sock;
}
Restart Nginx:
# systemctl restart nginx
In a web browser, visit http://YOUR-SERVER-WEB-ADDRESS-OR-IP/wsgi_app
, and you will see a test page with the python and GCC versions.
Delete the test.py
file you just created, and the location block you just added to /etc/nginx/nginx.conf
for wsgi_app
.
Restart Nginx:
# systemctl restart nginx
Stop uWSGI serving wsgi_app
:
# systemctl stop uwsgi@wsgi_app
Delete the /etc/uwsgi/wsgi_app.ini
and test.py
test files you just created.
