[AWIPS #POI-890489]: EDEX server file permissions post new install

> Hi folks,
> I have tried installing the current EDEX server on a new virtual machine 
> running RHEL 7.9. The VM has 20 cores allocated, 32 GB RAM, and the /awips2 
> path is a file system running on a pair of NVMe sticks on the host 
> motherboard. This is the same configuration that had been running the old 
> 18.x server (under a RHEL 6.x OS) for a number of years.
> 
> I have tried installing the software multiple times, always assuming that I 
> have done something wrong, but the system load continues to rise over time. I 
> have tracked it down to what looks like a file permission problem, where the 
> data files are owned by root, but the data processing scripts that want to 
> move files are run by the awips user.
> 
> Here are some pieces of evidence.

Hello,

Sorry you've been having some issues installing and running EDEX. I've got a 
couple clarifying questions to try and help you.

When was the last time you tried installing? Did you download the latest 
awips_install.sh script?

When was the last time you saw the stacked-up python processes? In one of our 
releases we did have an issue with this, but in our latest release all of those 
issues have been resolved.

You mentioned having "issues with the group install" - was that from running 
the awips_install.sh script? What was that error?

Nothing in /awips2/data_store should be owned by root. When you ran the regutil 
and ldm commands were you user awips or root?

Since there are things definitely not running/set up correctly let's have you:
1. Download the latest awips_install.sh script: 
wget -O awips_install.sh 
https://downloads.unidata.ucar.edu/awips2/current/linux/awips_install.sh
2. Make sure the script is executable
chmod 755 awips_install.sh
3. Run the install script - assuming you are running it with sudo/root? (Note: 
Running this script will remove any existing version of AWIPS that is installed)
sudo ./awips_install.sh --edex

Send us the output from the install and hopefully we can see if something is 
going awry during the installation.
