How uWSGI is implemented by distributors is different. uWSGI itself recommend two methods
unit template --> /usr/lib/systemd/system/uwsgi@.service uwsgi ini files --> /etc/uwsgi/searx.ini
The searx app can be maintained as know from common systemd units:systemctl enable uwsgi@searx systemctl start uwsgi@searx systemctl restart uwsgi@searx systemctl stop uwsgi@searx
The uWSGI Emperor mode which fits for maintaining a large range of uwsgi apps.
The Emperor mode is a special uWSGI instance that will monitor specific events. The Emperor mode (service) is started by a (common, not template) systemd unit. The Emperor service will scan specific directories for uwsgi ini files (also know as vassals). If a vassal is added, removed or the timestamp is modified, a corresponding action takes place: a new uWSGI instance is started, reload or stopped. Take Fedora and a searx.ini as example:to start a new searx instance create --> /etc/uwsgi.d/searx.ini to reload the instance edit timestamp --> touch /etc/uwsgi.d/searx.ini to stop instance remove ini --> rm /etc/uwsgi.d/searx.ini
The uWSGI Emperor mode and systemd unit template is what the distributors mostly offer their users, even if they differ in the way they implement both modes and their defaults. Another point they might differ is the packaging of plugins (if so, compare Install packages) and what the default python interpreter is (python2 vs. python3).
Fedora starts a Emperor by default, while archlinux does not start any uwsgi service by default. Worth to know; debian (ubuntu) follow a complete different approach. debian: your are familiar with the apache infrastructure? .. they do similar for the uWSGI infrastructure (with less comfort), the folders are:
The uwsgi ini file is enabled by a symbolic link:
ln -s /etc/uwsgi/apps-available/searx.ini /etc/uwsgi/apps-enabled/
From debian’s documentation (
could control specific instance(s) by issuing:
service uwsgi <command> <confname> <confname> ... sudo -H service uwsgi start searx sudo -H service uwsgi stop searx
My experience is, that this command is a bit buggy.
