Hello @suman_kumar_dey,
In “/opt/kaltura/app/configurations/apache/conf.d/enabled.apps.conf”, the aliases “/ apps” and “/apps/kea” overlap.
So that, the configuration script shows a warning.
But, I think that you do not have to worry about this warning.
Next, the apache needs modules “log_config_module” and “logio_module” for it use “% O” directive.
Have you confirmed that the apache has loaded these modules?
In the CentOS 6, you can list loaded modules by following command:
# apachectl -M
If apache have not load these modules, please look “LoadModule” statements in “/etc/httpd/conf/httpd.conf” or other apache configuration files.
Regards
