Veeam Free Linux Agent Install on Centos 7

If you are a junior admin that works with Vmware or Azure, learning Veeam backups can elevate your skills and value. This post will walk through the steps of setting up the free Linux backup agent on a Centos 7 virtual machine. Step 1: Lay the Foundation https://helpcenter.veeam.com/docs/agentforlinux/userguide/system_requirements.html?ver=30 https://helpcenter.veeam.com/docs/agentforlinux/userguide/installation_process.html?ver=30#dep Run uname -r and take note of the kernel version.

Introduction

In order to get some real hands on experience as a Linux admin; lab construction should be the first priority. I am setting out with a couple of goals: 1. Set up a KVM hypervisor. 2. Inside of that KVM hypervisor, install a Spacewalk server. Use CentOS 6 for deployments in order to not worry about SELinux. I wanted the lab to have an enterprise feel but wanted to utilize free open source software. Another requirement was a it needed to have a GUI (preferably web based). After a detailed review 2 operating systems peaked my interest and already came prepackaged with KVM. For those interested in reviewing all the options: https://www.linux-kvm.org/page/Management_Tools The first was Proxmox. Proxmox is Debian based OS and has very nice features with streamlined ease of use. Below is an example of the GIU and iso images can be found at https://www.proxmox.com/en/downloads/category/iso-images-pve The second offering I reviewed was Ovirt. Ovirt is Redha...

Proxmox Has Won Me Over

I intended to make Ovirt Node work since it is based off of Centos but within 10 minutes of install I am having to vim /etc/hosts and set Ip address to hostnames because I need to bypass FQDN requirements. Then I need to set up the Ovirt Engine which requires a lot of resources. I still do not know what purposes it serves. An hour later and I still have not spun up a VM. At this point I am starting to think I shouldn't use this platform. I scrapped Ovirt and spun up a Proxmox host. I will add a big tip here. Login to your router when during the Proxmox install and reserve the IP it is using. This will effectively bind that private Ip to the MAC address of the Proxmox host. This step is super important. Once you are done installing Proxmox all the network configurations are done for you automatically. You do not have to set up a bridge between host and Vms. I was able to install Proxmox and spin up a Vm in about 15 minutes with full network connectivity. The GUI also looks ver...
