CentOS 7. Which installer need to Download: Minimal, DVD, or Everything?

Size of CentOS 7 iso. To determine which package that you want to install/download (DVD, Everything, or Minimal).

4.0G CentOS-7-x86_64-DVD-1503-01.iso
7.1G CentOS-7-x86_64-Everything-1503-01.iso
696M CentOS-7-x86_64-LiveCD-1503.iso
1.0G CentOS-7-x86_64-LiveGNOME-1503.iso
1.2G CentOS-7-x86_64-LiveKDE-1503.iso
636M CentOS-7-x86_64-Minimal-1503-01.iso
360M CentOS-7-x86_64-NetInstall-1503.iso

Better to start with minimal, and add package needed with yum install package later on after installation.

Create your own vSphere 6 Private Lab

It is easy to create the vSphere Lab in your laptop!

These are the steps :

1. Prepare Storage :

EMC Appliance :

OR use open source NAS server (FreeNAS is easier, OpenFiler, etc)

2. Prepare Gateway, NTP, LDAP/AD, DNS

Create DNS and NTP easily with  this = http://www.virten.net/2013/12/howto-use-vcenter-server-appliance-vcsa-as-dns-server/

LDAP can be created easily with turnkeylinux openldap

3. Prepare vSphere ESXi

4. Prepare vCenter


High Level Best Practice Configuration yang perlu dicek untuk VMware vSphere Production Environment

Berikut ini ada beberapa konfigurasi best practice yang perlu dicek untuk mengetahui apakah environment VMware yang anda miliki saat ini sudah appropriate atau  tidak untuk production level. Ini adalah guidance secara high level saja. Untuk detailnya perlu dijelaskan lebih lanjut, mudah2an dapat saya teruskan untuk beberapa komponen dibawah ini.

Component Recommended Action Item
Compute Configure firewall rules and ports according to best practices.
Compute VMware vSphere ESXi Shell and SSH access should be configured per the customer security and manageability requirements.
Datacenter Use vCenter Server roles, groups, and permissions to provide appropriate access and authorization to the VMware virtual infrastructure. Avoid using Windows built-in groups (Administrators).
Datacenter Tasks and Events Retention Policy set in the environment.
Datacenter Size with HA host failure considerations.
Datacenter Set up redundancy for the management port (either using a separate vmnic or a separate uplink) and an alternate isolation response gateway address (if appropriate) for more reliability in HA isolation detection.
Datacenter Maintain compatible and homogeneous (CPU and memory) hosts within a cluster to support the required functionality for vMotion, vSphere DRS, VMware vSphere Distributed Power Management (DPM), VMware vSphere HA, and vSphere FT.
Network Verify that there is redundancy in networking paths and components to avoid single points of failure. For example, provide at least two paths to each network.
Network Configure networking consistently across all hosts in a cluster.
Network If jumbo frames are enabled, verify that jumbo frame support is enabled on all intermediate devices and that there is no MTU mismatch.
Network Minimize differences in the number of active NICs across hosts within a cluster.
Network Configure networks so that there is separation of traffic (physical or logical using VLANs).
Network Use DV Port Groups to apply policies to traffic flow types and to provide Rx bandwidth controls through the use of Traffic Shaping.
Network Use Load-Based Teaming (LBT) to balance virtual machine network traffic across multiple uplinks.
Network Use Network I/O Control (NetIOC) to prioritize traffic on 10GbE network uplinks.
Network Adjust load balancing settings from the default virtual port ID only if necessary.
Storage Minimize differences in datastores visible across hosts within the same cluster or vMotion scope.
Storage NFS and iSCSI storage traffic should be separated physically (for performance) and logically (for security).
Virtual Machines Limit use of snapshots, and when using snapshots limit them to short-term use.
Virtual Machines Verify that VMware Tools is installed, running, and up to date for running virtual machines.
Virtual Machines Verify that virtual machines meet the requirements for vSphere vMotion.
Compute Avoid unnecessary changes to advanced parameter settings.
Datacenter Enable bidirectional CHAP authentication for iSCSI traffic so that CHAP authentication secrets are unique.
Datacenter Disconnect vSphere Clients from the vCenter Server when they are no longer needed.
Datacenter Maintain compatible virtual hardware versions for virtual machines to support vMotion.
Licensing Verify that adequate licenses are available for vCenter Server instances.
Licensing Verify that adequate CPU licenses are available for ESXi hosts.
Network Distribute vmnics for a port group across different PCI buses for greater redundancy.
Network Change port group security default settings for Forged Transmits, Promiscuous Mode, and MAC Address Changes to Reject unless the application requires the defaults.
Storage Use shared storage for virtual machines instead of local storage.
Storage Size datastores appropriately.
Storage Allocate space on shared datastores for templates and media/ISOs separately from datastores for virtual machines.
Storage Use Storage I/O Control (SIOC) to prioritize high importance virtual machine traffic.
Virtual Machines As a security enhancement initiative, disable certain unexposed features.
Virtual Machines Limit sharing console connections if there are security concerns.
Virtual Machines Allocate only as much virtual hardware as required for each virtual machine. Disable any unused or unnecessary or unauthorized virtual hardware devices.
Virtual Machines Consider using the latest virtual hardware version to take advantage of additional capabilities.
Virtual Machines Use the latest version of VMXNET that is supported by the guest operating system.
Virtual Machines Use reservations and limits selectively on virtual machines that need it. Don’t set reservations too high or limits too low.
Virtual Machines Select the correct guest operating system type in the virtual machine configuration to match the guest operating system.

Step by Step for vCenter Upgrade from 5.1 to 5.5

I am taking this Tutorial from VMware Communitiies (VMTN). This is a very common questions to ask, so I re-post it again in this blog.

Make sure below 6 tasks has been completed before starting of vCenter Upgrade.

  1. 2 hours before the upgrade disable all Schedule VM backups for vCenter or 3rd Party Tools
  2. Once backup disabled request Database Team to backup below databases 30 mins before the vCenter upgrade –
    1. vCenter Server database
    2. SRM database
  3. On vCenter, make a copy of the SSL certificates, copy them backup folder
  4. Backup Inventory Service database. Follow below procedure
  • On the source machine, open the command prompt in the vCenter Server and change the directory to vCenter_Server_installation_directoryInfrastructureInventory Servicescripts.
  • Run the following command at the prompt to back up the Inventory Service database.
  • backup.bat -file gdciventoryvcenter.bak
  • When the backup operation finishes, the message Backup completed successfully appears, copy the file to backup folder
  1. Backup the SSO configuration
    1. Click on start/programs/vmware
    2. Select Generate vCenter Single Signon Backup bundle, this creates a zip file on the desktop
    3. Select Generate vCenter single Signon log bundle
    4. Copy these files to backup folder
  2. 5 minutes prior to upgrade of vCenter

    Create a snapshot of vCenter.

    ********** UPGRADATION **********

Once the jobs or tasks written in above completed, we will start with vCenter Server Upgrade from 5.1 to 5.5

We need to upgrade the vCenter Server in below sequence.

  1. Single Sign On – SSO
  2. vSphere Web Client
  3. vSphere Inventory Service
  4. vCenter Service
  5. vCenter Update Manager
  6. VMware Site Recovery Manager


  7. Single Sign On Upgrade:


  8. Mount the ISO and kick off the SSO installer under custom upgrade.
    1. All the required install files for all products we are upgrading are located on each VC server under “d:vCenter 5.5 and related”
