Magento 2 installer hangs at 73% during clean every single time?

[robert_gordon]

I am attempting to do a clean Magento2 install, yet the installation keeps hanging at 73%. 

OS: CentoOS 7 (fully patched)

Web Server: nginx (1.15)

Database: MySQL 5.7 (latest version)

I have made the recommended modifications to my php.ini file as well.

The installer hangs at this step in the process, every time:
Module 'Magento_Weee':
Installing data...

Questions:

1.  Where do I check logs to see why the install keeps failing at this exact same place?

2.  What should the EXACT permissions be on the Magento directories, in order to confirm this isn't a permissions issue?  I am installing via the latest 2.2.6 .gz tarball on my server at webroot/magento.

3.  The installer appears to hang each time while installing the sample data.  Is there an installer of 2.2.6 CE that does NOT have the sample data, to see if that install works?

If I remember right I had some similar problems on Ubuntu 18.04.

After I add :

include_path = "."

to php.ini on all Magento 2 sites I solved some problems.
