VMware, installing and deploying Vcenter Server

I. Introduction to VCenter Server

1. Introduction to VCenter Server

The two core components of vsphere are ESXi and vcenter Server. ESXi is a virtualized platform for creating and running virtual appliances, a service that acts as a central administrator for ESXi hosts connected to the network . VCenter server can be used to join resources from multiple hosts to the pool and manage those resources.

2. VCenter Server components and services

VCenter Server 6.0 is divided into two parts:

VMware Platform Services Controller Infrastructure Service Group

Includes vcenter Sigle sign-on (Single sign-on service), license service, Lookupservice, and VMware certification authorities.

vCenter Server Service Group

Includes vcenter Server, vsphere Web Client, Inventory (manifest) Service, vsphere Auto Deploy, vsphere ESXi Dump Collector, vsphere syslog Collector on Windows and vsphere syslog services for vcenter Server appliance

3. VCenter Server Deployment method

single-stage deployment :

VCenter Server and Platform Services controllers are deployed on a single virtual machine or physical server.

The installation of VCenter Server with embedded Platform Services Controller has the following advantages:

Vcenter Server and Platform Services Controller are not connected over the network, and because Vcenter server and

VCenter Server is not prone to failure with connection and name resolution issues between Platform Services controllers.

If you install VCenter server on a Windows virtual machine or physical server, fewer Windows licenses are required.

You will need to manage fewer virtual machines or physical servers.

Load balancers can be distributed across Platform Services controllers without the need for a load balancer.

The installation of VCenter Server with embedded Platform Services Controller has the following disadvantages:

Each product has a Platform Services Controller, which may have exceeded the required amount. This will consume more resources.

This model is suitable for small environments.

More than one deployment:

VCenter Server and Platform Services controllers are deployed on different virtual machines or physical servers.

You can share Platform Services controllers across multiple VCenter server instances.

You can install a Platform services controller, and then install multiple vcenter Server instances and register them with the Platform services controller.

You can then install another Platform services controller, configure it to replicate the data for the first Platform services controller, and then install the Vcenter Server instance and register it with the second Platform Services Controller.

The installation of VCenter Server with external Platform Services Controller has the following advantages:

The combination service in the Platform services Controller consumes less resources, which reduces memory consumption and maintenance.

You can include multiple VCenter Server instances in your environment.

The installation of VCenter Server with external Platform Services Controller has the following disadvantages:

VCenter Server and the Platform Services Controller establish connections over the network, which makes connection and name resolution problems easy.

If you install VCenter server on a Windows virtual machine or physical server, you will need more Microsoft Windows licenses.

You need to manage more virtual machines or physical servers.

Hybrid deployment:

An instance of VCenter Server installed on Windows can be registered in the Platform Services controller or Platform services controller device installed on Windows.

VCenter Server Appliance can be registered in the Platform Services controller or Platform services controller device installed on Windows.

Vcenter Server and vcenter server Appliance can be registered to the same Platform Services Controller in the domain.

There are many Platform Services controllers that can replicate their infrastructure data to ensure high availability of the system.

If the Platform Services Controller that originally registered the Vcenter server instance or vcenter server Appliance stops responding, you can add vcenter server or vcenter Ser Ver Appliance re-points to other external platform Services controllers in the domain.

4. Deployment requirements for VCenter server

1) hardware requirements 650) this.width=650; "Src=" http://s1.51cto.com/wyfs02/M01/85/83/ Wkiom1em5ras-pcaaaew0ehcqim379.png "title=" Hardware requirements. png "alt=" Wkiom1em5ras-pcaaaew0ehcqim379.png "/>

Important matters:

For vcenter server with embedded Platform services controller, you must add the hardware requirements of the Platform Services controller to the vcenter server hardware requirements based on the size of the environment 。

2) Storage requirements

650) this.width=650; "src=" Http://s5.51cto.com/wyfs02/M01/85/82/wKioL1em5ryDTGyhAAK9Zlstyn4041.png "title=" Storage requirements. png "alt=" Wkiol1em5rydtgyhaak9zlstyn4041.png "/>

3) Software Requirements

(1) VCenter Server Software Requirements

Make sure that your operating system supports VCenter Server.

Vcenter Server requires a 64-bit operating system, and Vcenter server requires a 64-bit system DSN to connect to the external database.

The earliest version of Windows Server supported by VCenter server is Windows Server SP2. Your Windows Server must have

Install the latest updates and patches. For a complete list of supported operating systems, see http://kb.vmware.com/kb/2091273.

(2) VCenter Server appliance Software Requirements

Vcenter Server Appliance is a pre-configured Linux-based virtual machine optimized for running VCenter server and associated services.

The VCenter Server Appliance package contains the following software:

SUSE Linux Enterprise Server Update 3 for vmware,64 bit version

PostgreSQL

Vcenter Server 6.0 and Vcenter Server 6.0 components.

VMware vcenter Server Appliance can be on ESXi host 5.0 or later or on a VCenter server instance

Deployed on 5.0 or later.

You can only deploy VCenter Server Appliance using the client integration plug-in. The plugin is an HTML installer for Windows that you can use to connect to the target server and deploy VCenter server Appliance on the servers. You can connect directly to ESXi 5.0.x, ESXi 5.1.x, ESXi 5.5.x, or ESXi 6.0.x hosts for which you want to deploy the device. You can also connect to vcenter server 5.0.x, vcenter server 5.1.x, vcenter server 5.5.x, or vcenter server 6.0.x instances to the ES in Vcenter server inventory The device is deployed on the Xi host or DRS cluster.

4) Database Requirements

VCenter server needs to use the database to store and organize server data.

Each VCenter Server instance must have its own database. For environments with up to 20 hosts and 200 virtual machines , a bundled PostgreSQL database can be used, and Vcenter Server Setup can install and set up the database for you during Vcenter Server installation.

Larger installation requirements provide a supported external database for the environment size.

During vcenter server installation or upgrade, you must choose to install the embedded database or point the VCenter Server system to any existing supported databases. VCenter Server supports Oracle and Microsoft SQL Server databases. For information about the supported version of the database server, see VMware products on http://www.vmware.com/resources/compatibility/sim/interop_matrix.php

The list of interoperability.

VCenter Server Appliance requires the use of databases to store and organize server data.

Each vCenter Server Appliance instance must have its own database. You can use a bundled PostgreSQL database contained in VCenter Server appliance, which can support up to 1,000 hosts and 10,000 virtual machines .

For external databases, VCenter Server Appliance only supports Oracle databases. These Oracle database versions are identical and appear in the VMware product interoperability list for the version of VCenter Server that you have installed. Please see

A list of VMware product interoperability on http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.

If you are using an external database, be sure to create a 64-bit DSN so that VCenter Server can connect to the Oracle database.

Ii. using embedded installation of Vcenter Server 6.0 on Windows Server

Steps

1 in the Software installer directory, double-click the Autorun.exe file to start the Setup program.

2 Select VCenter Server for Windows, and then click Install.

3 Follow the Installation Wizard's prompts to check the Welcome page and accept the license agreement.

4 Select VCenter Server and the embedded Platform Services Controller, and then click Next.

5 Enter the system network name (preferably the FQDN), and then click Next.

You can also enter an IP address. If you enter an IP address, provide a static IP address.

Important Make sure that the FQDN or IP address provided does not change. The system name cannot be changed after deployment. If the system name occurs

Changes, you must uninstall and reinstall VCenter Server.

Iii. using external installation of Vcenter Server 6.0 on Windows Server

1. Experimental environment

DB 192.168.10.12 Windows Server R2 Data Center Edition

PSC+VC 192.168.10.13 Windows Server R2 Datacenter Edition

Microsoft SQL Server SP1 Enterprise Edition

2. Prepare the external database

The database version must be Oracle 11g R2 or later and SQL Server R2 SP1 or later

after the database is installed Verify that the database service is fully functional

If you are ready to load the database and vcenter on the same server, you will need to turn off the report Services reporting service because the default port for reports services is 80, which conflicts with Vcenter, Of course, you can also modify the default port for report Services
