I want to setup a Galaxy instance in my server running on CentOS and I have an issue with configuring my Apache server with uWSGI. I have installed uwsgi with pip:
pip install uwsgi
and added in my Apache configuration file the following lines:
<Location "/galaxy">
Sethandler uwsgi-handler
uWSGISocket 127.0.0.1:4001
uWSGImaxVars 512
</Location>
as instructed by the Galaxy team. Nevertheless when I restart my web server I get the following error:
Invalid command 'uWSGISocket', perhaps misspelled or defined by a mod
and it fails to start again.
I'm very new to using Apache for proxying requests so I need any help I can get.
Thank you in advance.

I'm trying to deploy my first django app in windows 10 (x64), so installed apache 2.4(x86), installed and build mod_wsgi (4.9.1) with python 3.8(x86) (I have microsoft visual studio 2019 installed) and configured Apache httpd.conf and httpd-vhosts.conf files.
My app runs fine, but the annoying error 500 keeps showing every now and then, and goes away by refreshing the browser every time.
There seems to be a bug with python 3.8, so decided to upgrade to python 3.10 (X86),
Reinstalled mod-wsgi and other packages using pip in new virtual environment in the same directory, and reconfigured httpd.conf accordingly. now apache service fails to start with error: "windows could not start the Apache2.4 on local computer....".
If I change httpd.conf configuration to load and use the python3.8 , Apache starts with no error (but again Error 500 keeps showing).
by the way I tried the same with python3.9 (x64) and Apache 2.4 (X64), and apache fails to start again.
Any help would be greatly appreciated.
In httpd.conf:
This configuration fails:
LoadFile "C:/Program Files (x86)/Python310-32/python310.dll"
LoadModule wsgi_module "d:/django project/unemployment project/.venv/lib/site-packages/mod_wsgi/server/mod_wsgi.cp310-win32.pyd"
WSGIPythonHome "d:/django project/unemployment project/.venv"
This configuration works:
LoadFile "C:/Program Files (x86)/Python38-32/python38.dll"
LoadModule wsgi_module "d:/django project/unemployment project/venv/lib/site-packages/mod_wsgi/server/mod_wsgi.cp38-win32.pyd"
WSGIPythonHome "d:/django project/unemployment project/venv"
I'm trying to use mod_wsgi-express for a django project. This project will be served through the main instance of apache, with a proxy. My purpose is to serve a python 3 application with a mod_wsgi for python 2 installed on the "main" apache server. (I've many apps on the same server)
I've created a systemd service which should launch the mod_wsgi-express instance, using my own service file :
https://gist.github.com/frague59/87529fc28b098dd116f09be92cf66af0
and
https://gist.github.com/frague59/8de1d03800042db95c82452af280dffe
I've to mention that those scripts works on another server, same distro, same version (debian oldstable)
... but the mod_wsgi-express does not start : no error message, no log...
I've noticed that a dir is created in tmp:
/tmp/mod_wsgi-127.0.0.1:8081:993
I've tried to start the apachectl from here:
# apachectl configtest
And I have a weird message:
AH00526: Syntax error on line 241 of /tmp/mod_wsgi-127.0.0.1:8081:993/httpd.conf:
Invalid option to WSGI daemon process definition.
I posts the generated httpd.conf file for example:
https://gist.github.com/frague59/a6d8d26b704565b39f7352a7c16e07d3
Error seems to be around:

I'm really struggling here. I have a simple Python Flask REST API that I've developed. The API runs fine in my local development environment (Mac OS X) and when directly executed via the console on my EC2 instance.
I want to move this service into production and as such would like to host it behind Apache running on the EC2 instance. This is where I keep hitting a wall and I can't seem to get past the configurations and errors. I've research several articles online and questions here, none seem to be able to help me.
I'm hoping someone here can please provide me with step-by-step directions on how to deploy my service to production behind Apache running on an Amazon Linux EC2 instance.
Here are the steps I've taken:
Launched a basic Amazon Linux EC2 instance.
Apply updates to the instance, sudo yum update
Install Apache and WSIG, sudo yum install httpd24 mod24_wsgi
Start Apache, sudo service httpd start
Configure Apache to start automatically, sudo chkconfig httpd on
Test by hitting the DNS of my EC2 box. I successfully get the Amazon Linux AMI test page.
Adjust permissions on /var/www as follows
sudo groupadd www
sudo usermod -a -G www ec2-user
Logon/off and confirm membership, groups
sudo chown -R root:www /var/www
sudo chmod 2775 /var/www
find /var/www -type d -exec sudo chmod 2775 {} \;
find /var/www -type f -exec sudo chmod 0664 {} \;
Test by hitting DNS of my EC2 box - still good so far.
Now that I know my instance is running, I would like to create two folders where I can test and run my Python Flask code. I do so as follows:
I create two folders, one for development and one for production.
/var/www/rest-dev/
/var/www/rest-prod/
I setup a virtual environment within each of the folders and install Flask.
virtualenv env
env/bin/pip install Flask
I then place a copy of my service in each folder.
Then I set permissions on app.py, chmod a+x app.py
I can successfully execute ./app.py and test the service by hitting the DNS name + port 5000. It works.
Now this is where I get tripped up. My goal is to be able to hit api.example.com and have my service's root load up. In the example code below, "Hello, World!" should simply display.
I've followed the tutorials found here with no luck.
http://peatiscoding.me/geek-stuff/mod_wsgi-apache-virtualenv/
http://webpy.org/cookbook/mod_wsgi-apache
http://www.jakowicz.com/flask-apache-wsgi/
After executing any of the steps in any of the articles above, I get an HTTP error page and nothing loads anymore, including the default Amazon Linux AMI test page. Below are the pieces of code and configurations that I've changed. I haven't changed my httpd.conf ... should I? There are probably several other things I'm missing.
Can someone please help me by providing me the necessary steps in detail to correct my mistakes?
Many thanks in advance!
When I view the error_log for HTTPD, it lists errors like this:
mod_wsgi (pid=8270): Target WSGI script '/var/www/rest-dev/deploy.wsgi' cannot be loaded as Python module.
mod_wsgi (pid=8270): Exception occurred processing WSGI script '/var/www/rest-dev/deploy.wsgi'.
Traceback (most recent call last):
File "/var/www/rest-dev/deploy.wsgi", line 16, in <module>
from app import app as application
File "/var/www/rest-dev/app.py", line 2, in <module>
from flask import Flask
ImportError: No module named flask
Here is my deploy.wsgi file, located in the rest-dev folder:
import os
import sys
import site
# Add virtualenv site packages
site.addsitedir(os.path.join(os.path.dirname(__file__), 'env/local/lib64/python2.7/site-packages'))
# Path of execution
sys.path.append('/var/www/rest-dev')
# Fired up virtualenv before include application
activate_env = os.path.expanduser(os.path.join(os.path.dirname(__file__), 'env/bin/activate_this.py'))
execfile(activate_env, dict(__file__=activate_env))
# import my_flask_app as application
from app import app as application
Here is my vhost.conf file located in /etc/httpd/conf.d/
<VirtualHost *:80>
ServerName api.example.com
WSGIDaemonProcess webtool user=ec2-user group=www threads=5 home=/var/www/rest-dev/
WSGIScriptAlias / /var/www/rest-dev/deploy.wsgi
<directory /var/www/rest-dev>
WSGIProcessGroup webtool
WSGIApplicationGroup %{GLOBAL}
WSGIScriptReloading On
Order deny,allow
Allow from all
</directory>
</VirtualHost>
Here is my app.py example service code for reference:
#!env/bin/python
from flask import Flask
app = Flask(__name__)
#app.route('/')
def index():
return "Hello, World!"
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000, debug=True)
Turns out, in my deploy.wsgi file I'm referencing lib64 instead of just lib. All the site packages exist in lib.
After changing it and restarting Apache, I'm able to successfully hit my service from the URL.
how i can configure cherokee 1.2 server with uWSGI and web2py? after some googling I read some tutor about configure, but the cherokee version in that tutors are too old. is there any new tutorial or can somebody ste-by-step explain how to deploy web2py app in cherokee?
my system is Ubuntu 12.04, all dependents were installed, uWSGI was installed and cherokee too. my web2py folder located in /var/web2py with config.xml in it for uWSGI params. config.xml content is:
<uwsgi>
<pythonpath>/var/web2py/</pythonpath>
<app mountpoint="/">
<script>wsgihandler</script>
</app>
You can find a thoroughgoing description of just this type of setup in the book "web2py Application Development Cookbook." Here's the config.xml given in the text:
<uwsgi>
<pythonpath>/var/web2py</pythonpath>
<module>wsgihandler</module>
<socket>127.0.0.1:37719</socket>
<master/>
<processes>8</processes>
<memory-report/>
</uwsgi>
After that's in place, you're instructed to run the uWSGI stack as the user who owns the web2py installation:
$ uWSGI -d config.xml
According to the recipe provided in the book, you then launch cherokee-admin and configure the server via the webui (it should be listening on port 9090). They walk you through the setup of a remote host using the info in your config.xml file, creating a virtual host and then giving it a handler. There's also info on using a regex facility to serve static files.
I'm attempting to setup a generic Pyramid project to work with uWSGI through Cherokee, but constantly get a "no app loaded" error. All the research I've done doesn't really give me much to go on. Anyone have any ideas? Please note that I 'am' using a virtualenv via virtualenvwrapper.
This is from my development.ini
[uwsgi]
socket = 127.0.0.1:2626
master = true
processes = 1
virtualenv = /home/user/.virtualenvs/pyramid/
pythonpath = /home/user/Projects/ConventionMeStatic
And this is the command I've been trying to use to launch it: /usr/bin/uwsgi --ini development.ini --plugin python.
I can post any further details but there have been no other changes made to the project itself.
You have specified a virtualenv and a pytonpath, but you have not specified which app to load.
If you have a single-file app you can load that file with the --wsgi-file option, if you have a deployment.ini file you can use the --paste option as described here
http://projects.unbit.it/uwsgi/wiki/UsePaste
or the --ini-paste shortcuts described in examples section of the uwsgi wiki
