Origin uWSGI
|
||||
============
|
||||
|
||||
How uWSGI is implemented by distributors is different. uWSGI itself
|
||||
recommend two methods
|
||||
|
||||
`systemd.unit`_ template files as described here `One service per app in systemd`_.
|
||||
|
||||
There is one `systemd unit template`_ and one `uwsgi ini file`_ per uWSGI-app
|
||||
placed at dedicated locations. Take archlinux and a searx.ini as example::
|
||||
|
||||
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 file`_\s (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
|
||||
|
||||
Distributors
|
||||
============
|
||||
|
||||
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 :ref:`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::
|
||||
|
||||
/etc/uwsgi/apps-available/
|
||||
/etc/uwsgi/apps-enabled/
|
||||
|
||||
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 (``/usr/share/doc/uwsgi/README.Debian.gz``): You
|
||||
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.
|
||||
|
||||
Alltogether
|
||||
===========
|
||||
|
||||
Create the configuration ini-file according to your distribution (see below) and
|
||||
restart the uwsgi application.
