I am trying to install Kaltura v3.0.0 on RHEL-6 with Apache 2.2. It appears that Apache 2.2 does not come with mod_file_cache.so built as a loadable module. Is there a workaround for this? I can't find anything on the Kaltura web site and very little on the web. This is the error I am getting:

Verifing prerequisites


One or more prerequisites required to install Kaltura failed:

   Missing memcache PHP extension

   Missing file_cache_module Apache module

Please resolve the issues and run the installation again.

I also have the memcache PHP extension already installed, but it does not seem to recognize it.

I've also seen a lot of discussion that file_cache_module is not a very safe and/or appropriate tool. The discussions seem to suggest using mod_disk_cache instead.

I believe that I am able to recompile apache/httpd from scratch with mod_file_cache support enabled, but that would not be desirable in a production environment.

Peace,
Sean

I was able to get KalturaCE installed and working after compiling Apache from source and enabling mod_file_cache.

Is there any plan to switch KalturaCE to using mod_disk_cache instead as suggested by the developers of Apache?

Having to use a custom compiled web server in a production environment is not ideal for doing future updates on the server.

Peace,
Sean

I'm having the same concerns. Having a custom install of Apache in a production environment breaks so many things it isn't funny. It means I can't use the RHEL update network to maintain my server, which is a real problem.

Anyone at Kaltura reading this?

Same issue here. there also isn't a php-imap package for RHEL 6. That is more of a RH issue than a Kaltura issue though. RHEL 6 has been out for 6 months already. 6.1 is out now. It is unlikely that this mod will be included in any future release as it is deprecated.

I am running into the same issue. Sean, can you go over the steps you did to enable this? Thanks.

Same problem here. This is quite troublesome since I cannot install Kaltura CE at this point with

Not sure if this will have consequences as I proceed with Kaltura, but by editing the prerequisites.ini file in the installer folder and commenting the apache_modules[] = "file_cache_module" line.

This allowed Kaltura to install.

Next, after doing the include of the kaltura file into httpd.conf, the httpd server would no longer start. I had to edit /opt/kaltura/app/configurations/apache/my_kaltura.conf file and comment the two MMapFile lines...

Apache started at that point and I can get to the start page... I'll try to follow-up on any of the fallout.

I did this as well but after commenting the 2 mmapfile lines I get a "Starting httpd: [FAILED]" error when I try to start Apache, did you have any more luck ?

I got the VMware image put onto our vSphere farm (we're big VM users) and copied the mod_file_cache.so file from there and manually added it to the apache config, it registered fine.

CentOS 6 doesn't include mod_file_cache by default, so you have to build yourself this way:

1. yum install httpd-devel
2. do: rpm -qa | grep httpd
2. write down the version number. Mine is: 2.2.15
3. go get the exact version of httpd source from http://httpd.apache.org
4. uxtract the source to some directory
5. go to: /my/source/dir/httpd-/modules/cache
6. do: apxs -i -a -c mod_file_cache.c
7. there you go, you've got mod_file_cache.so in your /etc/httpd/modules
8. your httpd.conf supposed to be automatically updated too. Do check that one too
9. don't forget to restart httpd
10. continue to install Kaltura CE

Hope it helps

@ardhi enormously grateful.
As noted by the item 8, I just had to edit to / etc / httpd / conf / httpd.conf and add the line

LoadModule file_cache_module modules/mod_file_cache.so

Restart httpd and...

Failed to connect to database 127.0.0.1:3306 user:root. Please check the database settings you provided and verify that MySQL is up and running.

... and then I think it was caused by using the root account for the installation http://bit.ly/vs9jqz

I will create a new user

Thanks for your data

Hello all,

The attached script installs all required packages to compile mod_cache_file.so, it then retrieves the appropriate Apache sources [depending on the version of Apache you installed] and compiles the module.
It works for both RPM based distros [tested with CentOS 6.2] and deb based [tested with Debian testing].
Of course, it requires access to RPM/deb repos where needed packages can be retrieved from as well as root privileges needed in order to install the module.

Hope this will be of use :)

May the source be with you,

Jess Portnoy
