Question about OM5
Hello!
I try to run apache-openmeetings-5.0.0-M3 on a CentOS7-Server.
Is this also an Tomcat-embedded version? There is no ./red5.sh
$ ./admin.sh
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/openmeetings/cli/Admin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
$ java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)
$ echo $JAVA_HOME
/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64
$ echo $JRE_HOME
<empty output>
yum does not find a JRE.
Kind regards
Andreas

I read your manual. You also install VLC which I don't need on this server.
The packages required by openmeetings I installed from the repos and
did not compile for example sox, it's in the repo.
ffmeg I installed via
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rp
yum install ffmpeg ffmpeg-devel

Hello!
It's not clear to me if I should have a Tomcat installed at all.
I don't need it anymore on this server. Should I install a Tomcat9
or is this not needed and openmeetings will run nevertheless?
Excuse my inexperience with java and tomcat please!

Are you using this old Tomcat?
If not please remove it
If yes you need to provide additional environment parameters to startup
script

Maybe you also have Tomcat installed via YUM?
Usually ./bin/startup.sh do the job ...

CentOS?

Now I installed Java 11 in the CentOS 7 server.
$ java -version
openjdk version "11.0.6" 2020-01-14 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.6+10-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.6+10-LTS, mixed mode, sharing)
Executing ./start.sh says:
$ ./startup.sh
Cannot find /var/lib/tomcat/bin/setclasspath.sh
This file is needed to run this program
There is a setclasspath.sh in $OM5/bin only.
Don't know how to proceed.

As it is stated on main page "IMPORTANT: Java 11 is required"

To run this version use scripts from `bin` folder
