I upgraded to kaltura to 12.9.0 and tried to add an installtion of the ngninx server in my all-in-one installation.
After installation of the kaltura-nginx package i got the message output:

Feb 08 14:25:47 VIRTSRVBLC03 systemd[1]: Unit kaltura-nginx.service cannot be reloaded because it is inactive.

I think there is a file missing or something is wrong in an installation script?
I am using debian.

And another question is: In a cluster installation must the nginx be accessable for the clients or just for the kaltura servers?

Hello,

/opt/kaltura/nginx/conf/kaltura.conf.template is part of the kaltura-nginx package, the fact it isn’t present will cause issues, understandably…

What’s the output for the following commands on your machine?

# dpkg -S /opt/kaltura/nginx/conf/kaltura.conf.template

Should return:
kaltura-nginx: /opt/kaltura/nginx/conf/kaltura.conf.template

# dpkg -L kaltura-nginx |grep kaltura.conf.template

Should see:
/opt/kaltura/nginx/conf/kaltura.conf.template

If the file is not present, try aptitude reinstall kaltura-nginx

As for the other question: yes, when using the Nginx VOD module for delivery, Nginx must be accessible from all machines playback should happen from. The player will be making requests to Nginx to get the manifest and segments.
You can choose any port you wish for it during the configuration phase and you can also use a LB accessible to all clients and balance between Nginx nodes who are not accessible to the outside world.
When taking that approach, you will need to modify the DB records in the kaltura.delivery_profile table so that they point to the LB’s addr rather than the node directly.

Hi Jess

check! It returns the same

check! It returns the same

A reinstallstion over aptitude have got the same result.

It looks like something went wrong before the install package is copying the template file :confused:

Thanks

What happens if you run:

# aptitude download kaltura-nginx
# mkdir /tmp/nginx.deb
# dpkg -x kaltura-nginx_1.10.2-3_amd64.deb /tmp/nginx.deb/
# ls -al /tmp/nginx.deb/opt/kaltura/nginx/conf/kaltura.conf.template

?

…
of the command
# dpkg -x kaltura-nginx_1.10.2-3_amd64.deb /tmp/nginx.deb/
i got:
dpkg-deb: error: failed to read archive `kaltura-nginx_1.10.2-3_amd64.deb’: No such file or directory

So I run:
# dpkg -x /var/cache/apt/archives/kaltura-nginx_1.10.2-3_amd64.deb /tmp/nginx.deb/
# ls -al /tmp/nginx.deb/opt/kaltura/nginx/conf/kaltura.conf.template

-rw-r–r-- 1 root root 4237 Dec 28 18:43 /tmp/nginx.deb/opt/kaltura/nginx/conf/kaltura.conf.template

OK, meaning /opt/kaltura/nginx/conf/kaltura.conf.template is definitely included in the kaltura-nginx_1.10.2-3_amd64.deb.
What happens if you try:
# dpkg -i kaltura-nginx_1.10.2-3_amd64.deb
?

You can always try to remove kaltura-nginx completely with:
# aptitude purge kaltura-nginx
and then try to reinstall it.
Just make sure beforehand that you have no manual configuration changes you may have made in /opt/kaltura/nginx/conf/ since these will be deleted.

I purged the package now and reinstalled it. Now the install process went successfully throught.
I try now to configure it in my environment.

Thank you Jess

Most welcome. Even fine mechanisms like Debian’s APT sometimes screw up:)
Let me know should have further questions/issues.
