Requirements:

• Python virtualenv with nextgisweb installed
• QGIS 2.8 or higher

$ cd /path/to/ngw
$ git clone git@github.com:nextgis/nextgisweb_qgis.git
$ source env/bin/activate
$ pip install -e nextgisweb_qgis/

QGIS and PyQT4 dependencies are not listed in setup.py because it hard to install it in virtualenv. So lets copy this packages from system packages to virtualenv. On Ubuntu this libraries located in python-sip, python-qt4 and python-qgis packages.

# DST should point to virtualenv site-packages directory.
# If it is point to another place you have to modify DST definition.
# For example: DST=`python -c "import sys; print sys.path[-2]"`
$ DST=`python -c "import sys; print sys.path[-1]"`
$ echo $DST
$ cp `/usr/bin/python -c "import sip; print sip.__file__"` $DST
$ cp -r `/usr/bin/python -c "import PyQt4, os.path; print os.path.split(PyQt4.__file__)[0]"` $DST
$ cp -r `/usr/bin/python -c "import qgis, os.path; print os.path.split(qgis.__file__)[0]"` $DST

# Only for latest QGIS version (not for 2.8)
$ export PYTHONPATH=$PYTHONPATH:/usr/share/qgis/python
$ cp -r `/usr/bin/python -c "import PyQt, os.path; print os.path.split(PyQt.__file__)[0]"` $DST

You have to add --lazy-apps to the command line, in this way application will be loaded after master's fork, so each worker will get its thread.

[uwsgi]
lazy-apps = True

Beware as there is an older options named lazy that is way more invasive and highly discouraged (it is still here only for backward compatibility).

If you get an error message ERROR: Auth db directory path could not be created then you have to specify directory where an existing qgis-auth.db is located or created if not present. This directory needs to be writeable by uwsgi process user. For example:

[uwsgi]
env = QGIS_AUTH_DB_DIR_PATH=/var/www
