Installing Murano API via WSGI
==============================
This document is a guide to deploy murano using two WSGI mode uwsgi and
mod_wsgi of Apache.
Please note that if you intend to use mode uwsgi, you should install
``mode_proxy_uwsgi`` module. For example on deb-base system:
.. code-block:: console
# sudo apt-get install libapache2-mod-proxy-uwsgi
# sudo a2enmod proxy
# sudo a2enmod proxy_uwsgi
.. end
WSGI Application
----------------
The function ``murano.httpd.init_application`` will setup a WSGI application
to run behind uwsgi and mod_wsgi
Murano API behind uwsgi
-----------------------
Create a ``murano-api-uwsgi`` file with content below:
.. code-block:: ini
[uwsgi]
chmod-socket = 666
socket = /var/run/uwsgi/murano-wsgi-api.socket
lazy-apps = true
add-header = Connection: close
buffer-size = 65535
hook-master-start = unix_signal:15 gracefully_kill_them_all
thunder-lock = true
plugins = python
enable-threads = true
worker-reload-mercy = 90
exit-on-reload = false
die-on-term = true
master = true
processes = 2
wsgi-file = <path-to-murano-bin-dir>/murano-wsgi-api
.. end
Start murano-api:
.. code-block:: console
# uwsgi --ini /etc/murano/murano-api-uwsgi.ini
.. end
Murano API behind mod_wsgi
--------------------------
Create ``/etc/apache2/murano.conf`` with content below:
.. code-block:: ini
Listen 8082
<VirtualHost *:8082>
WSGIDaemonProcess murano-api processes=1 threads=10 user=%USER% display-name=%{GROUP} %VIRTUALENV%
WSGIProcessGroup murano-api
WSGIScriptAlias / %MURANO_BIN_DIR%/murano-wsgi-api
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
AllowEncodedSlashes On
<IfVersion >= 2.4>
ErrorLogFormat "%{cu}t %M"
</IfVersion>
ErrorLog /var/log/%APACHE_NAME%/murano_api.log
CustomLog /var/log/%APACHE_NAME%/murano_api_access.log combined
<Directory %MURANO_BIN_DIR%>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>
Order allow,deny
Allow from all
</IfVersion>
</Directory>
</VirtualHost>
.. end
Then on deb-based systems copy or symlink the file to ``/etc/apache2/sites-available``.
For rpm-based systems the file will go in ``/etc/httpd/conf.d``.
Enable the murano site. On deb-based systems:
.. code-block:: console
# a2ensite murano
# systemctl reload apache2.service
.. end
On rpm-based systems:
.. code-block:: console
# systemctl reload httpd.service
.. end
