Re: Step by Step build instructions (Updates)

[Jaime Balbino]

Hi,

I use this updated guide and now my install is OK. Thanks!

But:

1, I have source compile error ("Build Failure"). I use pre-compile build
r1340865-20-05-2012

2. Don't work OM interface install suggest
".//jodconverter-core-3.0-beta-4/lib". The full patch is correct.

3. In page 18 error persist: "GRANT ALL PRIVILEGES ON openmeetings.* TO
'openmeetings'@'localhost' IDENTIFIED BY" - space in " openmeetings. *"

4. All converters and record OK. I have recompile ffmpeg after install, but
run ok now.

Bye.

Hi Stephen,

Debian 6.0 guide. I had problems earlier in the guide exactly where
corrections were made.
On the server already running the OM 1.88. Now disabled.


> 1) What was the compile error? did you have the correct version of Ant?
I use correct Ant (1.83). I had the same problem with some libraries
that have been classified as deprecated. I'll try again and inform
you.

This link is OK. Commented that the installation screen suggests
another general link.

No. In two guides (Debian and Ubuntu) no space in "...openmeetings.* TO...".

I did the steps. But he showed videos on whiteboard with black screen
and did not convert the recordings. I retraced the same steps and it
worked. It did not error any of the times.

I could not test the script to the / etc/init.d/red5. I suggest you
remove the elements of text formatting and line breaks allow very
clear. When copying and pasting problems can happen.

The part of the reverse proxy and SSL I have not tested too.

I think the installation is still very difficult for those beginners.
I think this should be made explicit at the beginning of the text and
should have a summary of what each step on the first page.
(install linux, download the main packages, download packages
auxiliary building the core of OM, build text converters, image and
PDF converters, video converters, etc ...)

Thanks.

soffice and red5 daemon

[Jaime Balbino]

Hi,

There is one thing I do not understand. When I run the script "red5.sh
&" in the main directory I do not need soffice. But when I use the "/
etc/init.d/red5 the" soffice runs as daemon and can not be disabled so
that the text conversion to work.

The soffice daemon is no longer necessary because of JODConverter. Why
keep it inside the daemon red5?

Re: soffice and red5 daemon

[Jaime Balbino]

George,

If you stop the daemon red5 ("sudo /etc/init.d/red5 stop") and
restart from directory red5 ("sudo sh red5.sh"), you will see text
convertion run ok because JODconvert work on demand.

I try comment soffice line in red5 script, but text convertion don't
work and "HTTP 500 error" mensage display in OM interface.

Bye,
Jaime

New /etc/init.d/red5 without soffice daemon

[Jaime Balbino]

Hi,

I was able to eliminate the need for soffice daemon using my old script in:

http://kwlug.org/sites/kwlug.org/files/openmeetings-startup.tgz
(author: Raul Suarez ra...@yahoo.com)

Just download, unpack (tar -xvzf) and copy the file "red5" to "/etc /init.d/".

So OM 2.0 will run and convert text without turning on the soffice daemon.

PS: Do not know why I could not disable the daemon in the soffice
script Stephen.

Bye,
Jaime Balbino

Re: Moddel 1.9 plugin

[Jaime Balbino]

Hi,

I test this. But the new Moodle plugin is only 2.0 version. Don't run in 1.9.

I think the SOAP paraments change in OM 2.0.
