installation question

Hello,

I'm attempting to deploy pgadmin on my CentOS 7 machine.

I installed the pgdg repo:
yum install pgdg-centos96-9.6-3.noarch.rpm

and then pgadmin:
yum install pgadmin4-v1.x86_64

I then read the deployment guide:
https://www.pgadmin.org/docs4/1.x/server_deployment.html <https://www.pgadmin.org/docs4/1.x/server_deployment.html>

but it is unclear to me where the config_local.py file is supposed to go.

These are the locations of all the config.py files currently on my system:

/usr/lib/python2.7/site-packages/Mozo/config.py
/usr/lib/python2.7/site-packages/cupshelpers/config.py
/usr/lib/python2.7/site-packages/dnf/yum/config.py
/usr/lib/python2.7/site-packages/firewall/server/config.py
/usr/lib/python2.7/site-packages/firstboot/config.py
/usr/lib/python2.7/site-packages/iniparse/config.py
/usr/lib/python2.7/site-packages/yum/config.py
/usr/lib64/gedit/plugins/pythonconsole/config.py
/usr/lib64/pluma/plugins/pythonconsole/config.py
/usr/lib64/python2.7/distutils/config.py
/usr/lib64/python2.7/distutils/command/config.py
/usr/lib64/python2.7/logging/config.py
/usr/lib64/python2.7/site-packages/coverage/config.py
/usr/lib64/python2.7/site-packages/gnome_abrt/config.py
/usr/lib64/python2.7/site-packages/problem/config.py
/usr/lib64/python2.7/site-packages/setroubleshoot/config.py
/usr/lib64/python2.7/site-packages/speechd_config/config.py

Any help would be greatly appreciated.
