Ansible can be installed easily with yum, but you may have to add Ansible Engine repository as in the installation manual https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html
Sample playbook to test connectivity to Cisco APIC will be created too.
In this article I will show you how to install VSFTP daemon for Centos/Red Hat and how to configure it to chroot user, so that only a given home directory can be accessed.

There were not instructions available for my case, as ADC would be SAML SP and Google SAML IDP. I struggled with some parts of the configuration so I wll describe the necessary tasks here.
Note that AAA feature is required, so your ADC must be licensed with "Advanced" license.

In my case, old server platform was Red Hat 5 and Cacti was 0.8x version. As Red Hat 5 is old and you can't really upgrade it, I needed to migrate Cacti installation to a new Redhat 7.7 server. Besides that, Cacti was planned to be upgraded to 1.x version.

Following prerequirements are assumed for this example:
- Python 3.6 and PIP installed (this document shows a way: https://developers.redhat.com/blog/2018/08/13/install-python3-rhel)
- Offline target server is accessible and you can transfer files there
- Online server with Internet access
Occasionally you can find a situation where you have a network admin server in a restricted customer environment or in some other offline environment. I came accross to this a while ago and I followed this procedure to install some essential network tools. Server in my case was RedHat 7.5, but process is similar to any distribution.
To begin with, I built an identical server to my own VM environment - if you need a RedHat server with licenses, check their Developer portal 
Only requirement is that you are able to transfer files between your online server and your offline server - this may be tricky and in very restricted environments, might need so physical disk too. In my case I was luckily able to transfer the files through a Citrix RDP session.
In the code examples I have two servers: source is my online VM and target is the offline server.
