At present, the virtualization technology has become more and more mature, and many enterprises have begun to adopt and implement this technology, among which the server virtualization scheme of VMware occupies the vast majority of the service virtualization market. This paper mainly introduces ESXi, an important member of VMware virtualization system.

What is virtualization? virtualization is the transformation of hardware resources from physical to logical, breaking the original physical structure, so that users can manage these resources more flexibly, and allowing multiple operating systems to run on one physical machine at the same time. in order to maximize resource utilization and flexible management.

Advantages of Virtualization:

1. Reduce the number of servers and the cost of hardware procurement

2. Maximize the utilization of resources

3. Reduce the cost of computer room space, heat dissipation and electricity consumption.

4. Hardware resources can be adjusted dynamically to improve the flexibility of enterprise IT business.

5. High availability

6. Adjust the physical hardware without interrupting the service

7. Reduce management costs

8. Have more efficient disaster preparedness capability

You need to pay attention to the following points when installing Esxi:

1. ESXi 5.5can only be installed and run on 64-bit × 86CPU servers.

2. ESXi 5.5.The host is required to have a CPU with two cores (select the same vendor Intel or AMD for multiple ESXi networks, otherwise the advanced features provided by vSphere are not supported)

3. ESXi 5.5 requires at least the physical memory of 4GB

4. X64-bit CPU must support and enable hardware virtualization (VT-x or RVI)

5. ESXi 5.5 requires one or more gigabit network or 10GB Ethernet controllers

Any combination of 6, 1 or more controllers

Basic SCSI controller RAID controller

Let's install the ESXi system:

This is the software that will be used.

I use a virtual machine for simulation installation, so there is no need to adjust the BIOS order after inserting the CD.

First insert the CD, and then go to the following interface:

F2-View and change configuration F4-change the user interface to high contrast mode F12-shut down or restart the host cursor-move the selection Enter (enter) between fields-select menu items, save and exit spaces-switch value F11-confirm sensitive commands For example, reset configuration default value Esc-exit without saving changes Q-exit Syslog Alt+F1-switch to command line interface Alt+F2-switch back to graphical interface

The command line interface in ESXi 5.5 is disabled by default and needs to be enabled:

At this point, our ESXi system has been installed!

After the installation of the system, you can not directly add a virtual machine, you need to install a client controller, relative to the installation of the system, the installation of the controller can be the next step.

By default, the next step is to create a new virtual machine, and you need to choose the compatible one for the network card.

After the addition is completed, add the CD image and note that the connection needs to be checked when the power is turned on in the upper right corner.
