Hello Ferran Jorba,
I felt very nice to receive an immediate response. T'll try out the things
one by one, though regarding the following I have already created virtual
hosts;

>(virtual hosts).
Thus I have this virtual host in /etc/apache2/sites-enabled/wiki
<VirtualHost 117.218.165.51:80>
ServerName www.lokavidya.in
ServerAdmin kksurend...@iitbombay.org
DocumentRoot /usr/share/moin
...errorlog etc....
#WSGIScriptAlias /wiki /usr/share/moin/moin.wsgi
#WSGIDaemonProcess moin user=www-data group=www-data processes=5
threads=10 maximum-requests=10$
#WSGIProcessGroup moin
</virtualhost>
The commented out WSGI declaratives were forced to be outside in the main
apache2.conf for the
www.lokavidya.in/wiki to run.( if you are lucky the link will be live -
sorry if it is offline!)
And the /etc/apache2/sites-enabled/invenio ( and also the invenio-ssl),
which is essentially file written by the Invenio installation, except for
the WSGIScriptAlias / changed to /invenio to make the wiki run.
#WSGISocketPrefix /opt/invenio/var/run
WSGIRestrictStdout Off
<VirtualHost 117.218.165.51:80>
ServerName wikividya.dyndns.org
ServerAlias wikividya
ServerAdmin redhatads...@bsnl.in
DocumentRoot /opt/invenio/var/www
...Aliases...
WSGIDaemonProcess invenio processes=5 threads=1
display-name=%{GROUP} inactivity-timeout=3600 maximum-requests=10000
WSGIImportScript /opt/invenio/var/www-wsgi/invenio.wsgi
process-group=invenio application-group=%{GLOBAL}
WSGIScriptAlias /invenio /opt/invenio/var/www-wsgi/invenio.wsgi
WSGIPassAuthorization On
....
<Directory /opt/invenio/var/www-wsgi>
WSGIProcessGroup invenio
WSGIApplicationGroup %{GLOBAL}
Options FollowSymLinks MultiViews
AllowOverride None
Require all granted
</Directory>
</virtualhost>
I was reading the document
http://modwsgi.readthedocs.org/en/latest/configuration-directives/WSGIDaemonProcess.html
and read the following lines...
Note that having denoted that daemon processes should be created by using
the WSGIDaemonProcess directive, the WSGIProcessGroup directive still needs
to be used to delegate specific WSGI applications to execute within those
daemon processes.
Also note that the name of the daemon process group must be unique for the
whole server. That is, it is not possible to use the same daemon process
group name in different virtual hosts.
So I tried with the WSGI commands for the wiki inside its
<virtualhost>...WSGIProcessGroup moin...</virtualhost> but then the wiki is
not found!
I'll try the other suggestions, but making sure the wiki runs. Till then
Thanks&Regards
Surendran
