I had a chance to attend a local Vmware User in Anaheim last Friday, 10/13/2017. This is a free, one-day event organized by VMUG community. The day was packed with great topics covering Vmware’s full stack. One thing I really like about it is that it’s a small gathering and I got a chance to talk shop with other VMware architects and admins which to me was very insightful.
Well, that was a long break ;) A lot has happened over the last 18 months and I have transitioned over to more of a Full Stack Engineer/Architecture role. I will be covering not just Linux systems but OSX and Windows systems as well, oh my!
In this post we will create an NFS share that will be used by all the machines on our Host-Only network.
None of our client VM’s have direct access to internet so we’ll setup a proxy server that the machines can use to acess internet and do external yum installs from time to time.
We will now setup our BIND DNS server. DNS is used to translate IP Address to fully qualified domain names. We also need DNS for mail management through MX records.
Chrony is the now the default network time protocol for RHEL/Centos 7. Chrony is an alternative NTP client and server that is designed specifically for systems that are not online all the time.
We need DHCP to dish out IP Addresses to our VM’s.
I’m using VirtualBox since it’s free, stable and works well with OSX. If I’m deploying my lab from a linux machine, I will most likely use KVM since it is included in the EX200/300 directives. I will have to create a separate VM to practice KVM.
You’ll need to setup a lab to get started with your RHCE studies. My lab is deployed wholly from my laptop. I really don’t want to create an elaborate lab with multiple hardware servers and switches since I’d like to have a portable lab that I can take with me wherever I go. This is now possible with the advent of VM’s and containers but you’ll need a powerful, beefy laptop to host all these services.
