I purchased a number of micro-usb plugs (Uxcell a15061700ux0139) from Amazon to power up my arduinos. Unfortunately they didn't have a pinout with them. The linkback has the full document that I was able to find (thank you Jason Fox). For quick reference, here are the diagrams that he posted:

nZEDb

August 16th, 2018

Here is information pertaining to my nZEDb setup.

This implementation is on Centos 7. Centos 7 was installed from a USB stick on an Intel NUC (no cd/dvd drive and I've yet to get the Centos 7 installer to work over PXE).

Setting up a 'PXE Network Boot Server' for Multiple Linux Distribution Installations in RHEL/CentOS 7

Additional steps for Centos 7

Install the EPEL repository: yum install epel-release

Timezone for PHP is: America/Los_Angeles

The version of nZEDb at the time of this install required PHP7 but Centos 7 has Centos 5.6. Here is how to Install PHP 7 on Centos 7.

Here is how to turn the firewall off on Centos 7

After installing the DB (I used MariaDB), I needed to populate the database timezone tables: 'mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql'
