Zimbra: How to install Zimbra 8.7.x in an automated way on CentOS/RHEL – with Chat and Drive!

Greetings friends, the Zimbra Community has that magic that makes you keep writing every day, commenting in forums, or contributing to GitHub with Scripts. As many of you know, I created a Script called ZimbraEasyInstall some time ago that helped us to deploy a Zimbra instance on Ubuntu in a very simple way. The other day I received an update to this code (thanks to Luis Perez) and now it also supports CentOS/RHEL, so today I want to show you how easy it is to install Zimbra Collaboration 8.7. x, in CentOS/RHEL in a completely automated way, here we go.

Microsoft: Project Honolulu Technical Preview – the Dashboard that will delight every IT Administrator

Greetings friends, Microsoft presented during the Microsoft Ignite this year the new Project Honolulu, also gave us access to a Technical Preview that of course we wanted to install. The "Honolulu" project is the culmination of an important customer feedback work, which has directly shaped the direction of the product and investments. With support for hybrid or traditional servers, the "Honolulu" Project provides a quick and easy solution for common IT administrative tasks as well as a lightweight deployment. The Honolulu Project is one of the best products that I have tested by Microsoft, and is that the simplicity of it, the capabilities it has, plus the speed and lightness of the package make it indispensable today, even being a Technical Preview.

What is Project Honolulu?

Honolulu is a set of locally deployed, browser-based management tools that enables local management of Windows servers without Azure or cloud dependency. Honolulu provides IT administrators with full control over all aspects of their server infrastructure, and is particularly useful for managing private networks that are not connected to the Internet. Honolulu is the modern evolution of in-box management tools such as Server Manager and MMC. It is complementary to System Center and Operations Management Suite, and is not intended to replace these products and services.

The new VCSA 6.5 comes with many enhancements such as HA, Backup, and very basic web monitoring to see CPU and RAM, I leave you some interesting articles: Without further delay, let's start the article, at the end we can have a Dashboard similar to this one using the always recommended PRTG Network Monitor:

That's what this Post is about:)

Veeam: GitHub repository with quick downloads links for Veeam Agent for Linux

Greetings friends, I have already told you on my Spanish Blog many times the advantages of using the new, and free, Veeam Agent para Linux, I leave you some of the best entries about it: Downloading from the official Veeam website has two small drawbacks, many times we want to install the Veeam Agent para Linux quickly on our servers, but we have to go through the long and cumbersome process of downloading the Veeam website, and the second, that once we download several products we start receiving a lot of emails related to other products or resources such as webinars. That's why I've put together a GitHub project with quick links to all packages with the different versions of Veeam Agent para Linux:

SEE GITHUB PROJECT

This will be as simple as copying the download link and use the wget on the server where we want to install Veeam Agent for Linux. I hope this resource it's useful for you all.

Veeam: Integration of AWS Storage Gateway with Veeam – Backups and backup copy in Cloud

Greetings friends, the first strong post of September, today I bring you a very entertaining post about Veeam Backup and Replication on a Repository based on AWS Storage Gateway, and as it has stayed a little long I want to leave here the menu to move you faster:

AWS Storage Gateway - quick overview

AWS Storage Gateway allows us to consume certain Amazon Web Services resources locally through a virtual appliance that we deploy in our Infrastructure, so our VMs view the resources as if they were local, while the information is replicated in an encrypted and compressed way to the Amazon Cloud. AWS Storage Gateway allows us to create different resources:
  • File Share: Which is nothing more or less than an NFS where we can connect computers that will see a traditional network drive and store files there.
  • Volumes: Where we can consume by iSCSI, volumes that we can connect to Windows, Linux, etc., and that will be replicated later.
  • Tapes: Virtual tape drives with which we can launch backups with Veeam for example, as if a real tape was involved, and thus get a more durable storage such as tapes, but in Cloud.
We can store the information in three different types of Amazon storage:
  • Amazon S3, recommended for files or volumes that we use frequently.
  • Amazon Glacier, if what we are saving is not accessed frequently.
  • Amazon EBS Snapshots.
This is how our Veeam Backup and Replication Infrastructure with AWS Storage Gateway would look like.

Zimbra: VMware Content Library with Zimbra Collaboration templates ready to deploy

Hello, everyone, I've been working with the VMware Content Library for quite some time, I've blogged about it here in Spanish. So, I've decided to create my own Zimbra Content Library, one of the first in the entire world, so you can sync it and deploy Zimbra in a really easy way.

Zimbra Templates

For the very first version of this project, I've used the latest Zimbra Collaboration 8.7.11 GA, and for the OS I've chosen Ubuntu 16.04 LTS, here are more details about this template:
  • vCPU: 4
  • vRAM: 8GB
  • vDISK1: 50GB / partition and SWAP
  • vDISK2: 100GB /opt partition
  • SCSI Controller: VMware Paravirtual
  • Networking: VMXNET3 - IP 192.168.1.150
  • Template compatible with VMware 5.5 and above
Another related topics
  • It does include the Open VMware Tools
  • OS Credentials:
    • User: oper
    • Password: Zimbra2017
  • Zimbra Credentials:
    • User: admin
    • Password: Zimbra2017
On this first version, we have only a single template with a Zimbra Single Server. But one of the benefits of VMware Content Libraries is that as soon I upload more templates or ISOS, you will automatically have them.

How to connect to the Zimbra Content Library

We can manage our VMware Content Library directly from the vSphere Web Client Flash, or even the new HTML Client, available starting vSphere 6.5 U1 or with the fling as I've explained multiple times on this Spanish blog post. The first step is to select a name for this Content Library and the vCenter Server:

PRTG: How to monitor the status, disks, free space and much more from a QNAP NAS using PRTG

Hello, everyone, I'm lucky enough to have on my Homelab a QNAP NAS, I wrote in Spanish some articles about how you can integrate QNAP with VMware: At the same time, it's really important to have a good RAID configuration or a proper Network Infrastructure, we don't need to forget how to monitor properly the QNAP status, which means all disks, temperature, S.M.A.R.T, etc. and we can achieve this in a quicker way using PRTG. At the end of this Blog post, you might be able to have a PRTG Map like this one, which I've built in ten minutes:

How to configure SNMP on a QNAP NAS

First thing before continue is to think if we want to use SNMP v1/v2 or choose SNMP v3, in this particular case, I've chosen SNMP v1/v2 to reduce complexity. Once logged in on the QNAP, you can go to ControlPanel - Network & File Services and click on the SNMP section
