I am using Apache Server with mod_wsgi for hosting my python django
applications. Versions: Python 3.9.18 Server version: Apache/2.4.57
mod-wsgi==4.7.1
One of my application virtual host configuration with two different
versions:
#Students Webservice Config
Listen 9002 <VirtualHost *:9002>
ServerName test.myapp.com
ErrorLog /var/log/webservice_error.log
WSGIPassAuthorization On
WSGIDaemonProcess Tes9002 python-path=/home/uoadmin/releases/1.0.0
/students:/home/admin/releases/1.0.0/shared display-name=%{GROUP}
WSGIProcessGroup Tes9002
WSGIApplicationGroup %{GLOBAL}
WSGIScriptAlias / /home/admin/releases/1.0.0/students/conf/wsgi.py
<Directory /home/admin/releases/1.0.0/students/conf>
<Files wsgi.py> Require all granted </Files>
</Directory>
</VirtualHost>
<VirtualHost *:9002>
ServerName dev.myapp.com
ErrorLog /var/log/webservice_error.log
WSGIPassAuthorization On
WSGIDaemonProcess Dev9002 python- path=/home/uoadmin/releases/1.1.0
/students:/home/admin/releases/1.1.0/shared display-name=%{GROUP}
WSGIProcessGroup Dev9002
WSGIApplicationGroup %{GLOBAL}
WSGIScriptAlias / /home/admin/releases/1.1.0/students/conf/wsgi.py
<Directory /home/admin/releases/1.1.0/students/conf>
<Files wsgi.py> Require all granted </Files>
</Directory>
</VirtualHost>
So, When the source code is modified I can referesh the wsgi daemon using
touch /home/uoadmin/releases/1.1.0/students/conf/wsgi.py touch
/home/uoadmin/releases/1.0.0/students/conf/wsgi.py But when I added new
virtualhost to the above configuration file or else when I modify above
file the apache server unable to recognize modifications made the existing
virtualhost or newly added virtualhost until doing apachectl graceful (or)
apachectl restart (or) systemctl reload httpd but all the commands above
killing the ongoing requests forcefully directly terminating them.
How to handle above situation.
I want to know how will apache server recognize modifications to
virtualhost or newly added virtual host without reloading or restarting.
If above is not possible then is there anyway for restarting or reloading
apache server gracefully that is without terminating or killing other
ongoing requests or daemons while using apache server + mod_wsgi for
serving python with django?
reload and restart gracefully are not working for mod_wsgi that is they are
forcefully killing other processing daemons`.
I also posted this on stackoverflow:
