Invalid path

FrankCTS · Post by **FrankCTS** » Wed Mar 27, 2024 9:14 pm

Hello all,

I have been having zero luck trying to set up OpenEMM on a AlmaLinux server.

I have gotten to the point where I can run the OMT.sh script, and I am taken to the Configure Basic Enviornment menu:

Code: Select all

Current menu: Configure basic environment (Java, Tomcat, Tomcat-Native, Wkhtml, Proxy)

Current webapp basic configuration:
 JAVA_HOME:     /usr/lib/jvm/java-11-openjdk-11.0.22.0.7-2.el9.x86_64
 CATALINA_HOME: /opt/tomcat/
 Tomcat-Native: None
 WKHTMLTOPDF:   None
 WKHTMLTOIMAGE: None
 PROXY:         None

However, I am met with the following error when I try to enter a path for Tomcat

Code: Select all

Please choose entry to change (Blank => Back):
 > Tomcat-Native
Please enter path for optional Tomcat-Native (Blank => Skip configuration of Tomcat-Native, 'Install' for installation):
 > /opt/tomcat
Invalid path for Tomcat-Native

I have also tried putting a trailing '/' character after tomcat.

I have checked the folder and the openemm user has access privileges for it.

Code: Select all

[openemm@vps-b74dbee8 opt]$ ls -lah tomcat/
total 13M

Is there something I am missing?
I should also note that many guides I have found make mention of a "OpenEMMInstaller.sh" script file, but this script is completely absent from my downloaded OpenEMM package.

Tomcat-Native is legacy (see Install & Admin Guide), you do not need it. The official guides are here: https://wiki.openemm.org/

Hello Maschoff,

Checking the installation and administration Guides from the link you sent, (OpenEMM 24.04: OpenEMM 24.04 Installation & Administration Guide 1.0.1),
I am seeing nothing indicating that Tomcat-Native is legacy. It's actually listed as a dependency in the guide.
Have the guides not been updated?

How do I proceed with the installation?
Again, I do not have this "OpenEMMInstaller.sh" script file that many guides mention. It did not come with my download.
Is this script file necessary to proceed? How do I obtain it?

Post by **maschoff** » Fri Apr 12, 2024 3:56 pm

I could not find the location where the Install&Admin guide lists Tomcat Native as required, please advice.

And where did you find references mentioning "OpenEMMInstaller.sh"? This has been replaced by OMT.sh a long time ago.

I found it on pg 25, section 6.3, Tomcat Deployment.
This section says "OpenEMM needs web application engine Tomcat for the frontend services".

It is also found on pg 13, section 3.1.1, Software Stack Roadmap / End of Life.
Some parts, such as the section for Postfix, or Linux, clearly state some technologies/OS are discontinued or have dropped support.
The Tomcat section does not say anything about it being legacy or discontinued.

And where did you find references mentioning "OpenEMMInstaller.sh"? This has been replaced by OMT.sh a long time ago.

This was thru trying to troubleshoot online.
Almost every single resource online on how to install this software made mention of using the OpenEMMInstaller.sh script.
I thought after reading the OMT.sh script that this may have replaced it, but made mention of this to help any potential replies in the thread.

Thank you for your help.

Tomcat and Tomcat Native are two different things. Of course, you need Tomcat to run the OpenEMM frontend.

I recommend to not rely on dubious "online resources" but to use https://wiki.openemm.org as the source of truth regarding OpenEMM.

The general wiki so far has been zero help, considering all the videos for tutorials are in German.

The installation manual has been a waste of time, but going back to the wiki, I am seeing that we can build OpenEMM from Github.

Following its instructions, I have cloned the Github repository to the "/tmp/openemm/" directory.

I then followed the following commands,

Code: Select all

$ sudo su -
# cd backend
# ./build-backend.py

Only to be met with the following error messages:

Code: Select all

Build binaries
make: *** src/c/lib: No such file or directory.  Stop.
failure: call to make -C src/c/lib all results in 2

the root user is the owner of all the backend files:

Code: Select all

[root@vps-b74dbee8 openemm]# ls -lah

drwxr-xr-x.  	5 root root   	81 Apr 15 18:34 	.

drwxr-xr-x. 	13 root root 	4.0K Apr 15 18:34 	frontend

What could the issue be here?

Which operating system do you use to build the executable code of OpenEMM?

Wkn · Post by **Wkn** » Tue Apr 16, 2024 2:18 pm

Missing libraries have been added.
Please try again

This is running on AlmaLinux.

Still getting the same error codes.

We just tried with

$ git clone https://github.com/agnitas-org/openemm
$ cd openemm/backend
$ chmod 755 build-backend.py
$ ./build-backend.py

and it worked.

Looking at this, I missed the chmod. Didn't see anything on there about chmod 775 the other day when I was going thru the guide.
This part is working, however I am met with the following errors when I try to built frontend:

OpenEMM 19.10 does not work with Java 11. You should use a later version of OpenEMM.

FrankCTS · Post by **FrankCTS** » Wed Apr 17, 2024 6:37 pm

I literally just pulled OpenEmm from Github this morning.
I have no idea why it is on ver19.
How do I upgrade this to the newest version?

EDIT:
I downloaded the source files for ver 23.10 from the Github repo.
I went thru the same process I had done previously.
Ran into the same exact error.
