实验2++Xen的安装、部署和配置

云计算课程实验实验二Xen的安装、部署和配置一．实验目的1. 掌握Linux基本操作命令2. 配置Yum数据源3. 学习如何安装、配置和使用Xen二．实验要求实验前需要在一台物理机上已安装好CentOS 5.4或者CentOS 5.5。

三．实验内容（一）Linux基本操作命令本实验的所有操作是基于Cent0S 5 Linux操作系统的，适用于CendOS 5.4和CentOS 5.5。

Linux常用基本命令包括：ls,cd,mkdir,rm,man,cat,ssh,yum,vim,vi,mount,umount等。

（二）搭建本地镜像服务器和设置Yum客户端Yum（全称为 Yellow dog Updater, Modified）是一个在Fedora和RedHat以及SUSE、CentOS中的Shell前端软件包管理器。

基于RPM包管理，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软体包，无须繁琐地一次次下载、安装。

CentOS中有很多软件包，我们可以在安装操作系统时定制安装相关软件包，也可以在安装完操作系统后通过Yum来安装这些软件包，Yum能自动处理软件包依赖关系，使得安装软件更加容易。

一般情况下我们在系统上安装相应软件包时需要通过Yum从相应的镜像服务器下载相关的软件包进行安装。

我们只需要配置Yum客户端，设置镜像的远程路径即可在客户端方便的完成安装。

（三）安装XenCentOS支持Xen虚拟化，我们只需要在安装操作系统时选择虚拟化支持或者在已安装的系统上安装支持Xen的内核和相关工具就可以完成Xen的安装。

Xen安装完毕并使用新内核重新启动后，系统中将运行Domain 0，使用Domain 0，我们可以创建多个虚拟机。

四．实验步骤指导1．设置Yum客户端Yum的配置文件位于/etc/yum.repos.d/目录下，在本实验中，我们只需要修改CentOS-Base.repo文件。

Xen安装过程

Xen安装过程1、什么是XenXen 是一个开放源代码的para-virtualizing虚拟机（VMM），或“管理程序”，是为x86架构的机器而设计的。

Xen 可以在一套物理硬件上安全的执行多个虚拟机；Xen是基于内核的虚拟程序，它和操作平台结合的极为密切，所以它占用的资源最少。

什么是虚拟机呢？可能大家知道VMWARE吧，是的，Xen就是类似这样的程序，比如我们可以在Fedora 上虚拟安装和使用Slackware、Debian、Gentoo ... ... 等发行版。

因为Xen是基于内核的，相对VMWARE 来说，它占用的系统资源也就是VMWARE的百分之几左右。

1.1 Xen的特性虚拟机的性能更接近真实硬件环境；在真实物理环境的平台和虚拟平台间自由切换；在每个客户虚拟机支持到32个虚拟CPU，通过VCPU热插拔；支持PAE指令集的x86/32, x86/64平台通过Intel 虚拟支持VT的支持来用虚拟原始操作系统（未经修改的）支持（包括Microsoft Windows）；优秀的硬件支持.支持几乎所有的Linux设备驱动1.2 Xen的应用范围服务器整合：在虚拟机范围内，在一台物理主机上安装多个服务器, 用于演示及故障隔绝；无硬件依赖：允许应用程序和操作系统对新硬件的移值测试；多操作系统配置：以开发和测试为目的，同时运行多个操作系统；内核开发：在虚拟机的沙盒中，做内核的测试和调试，无需为了测试而单独架设一台独立的机器；集群运算：和单独的管理每个物理主机相比较,在VM级管理更加灵活,在负载均衡方面,更易于控制,和隔离;为客户操作系统提供硬件技术支持：可以开发新的操作系统, 以得益于现存操作系统的广泛硬件支持,比如Linux；2、Xen的一点理论基础;基于Xen的操作系统，有多个层，最底层和最高特权层是Xen程序本身。

Xen 可以管理多个客户操作系统，每个操作系统都能在一个安全的虚拟机中实现。

xenapp安装指南笔记十（pass

xenapp安装指南笔记十（passCitrix recommends enabling passthrough client authentication. When the user connects to applications published on different servers, passthrough client authentication enables XenApp to automatically pass a user’s credentials from the initial server to the server hosting the next application. This prevents the user from having to re-authenticate when opening applications on different servers.Citrix建议启用passthrough client authentication功能。

当用户与“在不同服务器上发布的应用”建立连接的时候，passhrough client authentication 功能会让xenapp自动把认证信息从第一台服务器传递到另一台托管其他用用的服务器。

这样可以避免用户在不同服务器上打开应用程序需要再次认证的“尴尬”。

这张插图示意认证传递过程If the pass-through authentication feature is not enabled before deploying the clients to end users, users must reinstall the clients with this feature enabled before pass-through authentication will work. T o configure pass-through client authentication functionality on the server, install any Citrix XenApp Plugin for Hosted Apps — Program Neighborhood, the Citrix XenApp plugin, or the Citrix XenApp Web Plugin — on each XenApp server before Setup. If you are deploying the XenApp plugin as the client for users, install the XenApp plugin on your server as the pass-through client. Then, configure these pages during Setup:Passthrough Authentication for the Passthrough Client. Select Yes to enable pass-through client authentication.Server Address for the Passthrough Client. If you installed the Citrix XenApp plugin as the pass-through client, specify the URL for your XenApp Services site. For example, http://yourservername/Citrix/PNAgent.如果没有在为用户部署客户端之前启用passthrough authentiction 功能，用户必须重新安装客户端，来启用passthrough authentication功能。

You will find it quite easy to mount AWK-6222 on the wall, as illustrated below. STEP 1:Attach the wall-mounting kit with M4 screws, as shown in the diagram below:STEP 2:Mounting the AWK-6222 on the wall requires 4 screws. Use the AWK-6222 device, with wall-mounting kitattached, as a guide to mark the correct locations of the 4 screws. The heads of the screws should be between 5.5 mm and 8.5 mm in diameter, and theshafts should not be more than 5.0 mm in diameter, asshown in the figure.Do not drive the screws in all the way into the wall—leave a space of about 2 mm to allow room to slide the wall-mounting kit between the wall and the screws.STEP 3:Once the screws are fixed into the wall, insert the four screw heads through the large opening of the keyhole-shaped apertures, and then slide the AWK-6222 downwards, as indicated to the right. Tighten the four screws for added stability.DIN-Rail Mounting (Optional)The DK-DC50131 die-cast metal kit canbe bought separately, and enable easy androbust installation for the AWK-6222. Apair of DK-DC50131s is needed forDIN-rail mounting. To install the DIN-railmounting kits, tightly attach the twoDIN-rail mounting kits on the rear panel ofAWK-6222 with 12 screws (6 screws foreach kit).To InstallSTEP 1:Use the recessed button on the spring-loaded bracket to lock it into position. STEP 2:Insert the top of the DIN rail into the slot just below the upper hook of the DIN-rail mounting kit. Push the AWK-6222 toward the DIN rail until the DIN-rail attachment bracket snaps into place.To ReleaseSTEP 1:Pull out the two spring-loaded brackets from the bottom until they are fixed in the “release” position.STEP 2:Pull the AWK-6222 out and upward.Wiring RequirementsYou should also pay attention to the following items: •Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.NOTE Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.•You can use the type of signal transmitted through a wire todetermine which wires should be kept separate. The rule of thumb is that wiring with similar electrical characteristics can be bundled together.• Keep input wiring and output wiring separate.• It is strongly advised that you label wiring to all devices in the system for easy identification.Grounding Moxa AWK-6222Grounding and wire routing help limit the effects of noise due toelectromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.Installations with Unstable Power InputsThere are cases where the device has to be wired to the same power source as other equipment. In such cases if equipment such as motors that are connected in the circuit draw a large amount of current during operation, the transient voltage drop could potentially cause the AWK to become unstable. Installing a DC/DC power isolator between the two equipment is recommended to isolate the transient effect in and to ensure a stable power input for the AWK.Installations with Cable Extended Antennas for Outdoor ApplicationsIf the antenna or the AWK device is installed outdoors or in an open-air setting, proper lightning protection is required to prevent direct lightning strikes on the AWK device. In order to prevent coupling currents from nearby lightning strikes, a lightning arrester should be installed as part of your antenna system. Ground the device, antenna, as well as the arrester properly to provide maximum outdoor protection for the device.Arrester Accessories • SA-NMNF-01: Surge arrester, N-type (male) to N-type (female) •SA-NFNF-01: Surge arrester, N-type (female) to N-type (female)Wiring the Redundant Power InputsThe AWK-6222 must be connected to a power-over-Ethernet (PoE) IEEE 802.3af compliant power source or an IEC60950 compliant limited power source. When AWK-6222 is powered via DC power, the M12 A-coding connector on the bottom panel is used for the AWK-6222’s two redundant inputs. The pin assignment is shown below:Pin Power Input1 V1+ 2V2+ 3V1- 4 V2- 5GNDWiring the Digital Inputs and Relay Contact (Digital Output)The AWK-6222 has two sets of digital input—DI1 and DI2. Each DIcomprises two contacts of the 8-pin M12 connector on the AWK-6222’s bottom panel. These two digital inputs can be connected to digital-output-enabled sensors for on-site status monitoring.The AWK-6222 also has one relay output, which consists of the twocontacts. These relay contacts are used to detect user-configured events. The two wires attached to the relay contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the relay circuit will be closed.A field-installable plug, M12A-8PMM-IP68, is recommended for connecting the AWK-6222’s DIs and relay.Communication Connections10/100BaseT(X) Ethernet Port ConnectionThe 10/100BaseT(X) ports located on the AWK-6222’s bottom panel are used to connect to Ethernet-enabled devices.The pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports are shown below.MDI Port Pinouts MDI-X Port Pinouts8-pin RJ45Pin Signal 1 Tx+ 2 Tx- 3 Rx+ 6 Rx-Pin Signal 1 Rx+ 2 Rx- 3 Tx+ 6 Tx-Pin Signal 1 Relay 2 3 DI1 I1 4 DI1 COM_1 5 DI2 I2 6 DI2 COM_2 7 Reserved8RS-232 ConnectionThe AWK-6222 has one RS-232 (8-pin RJ45) console port located on the bottom panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect the Moxa AWK-6222’s console port to your PC’s COM port. You may then use a console terminal program to access the AWK-6222 for console configuration.Console Pinouts for 10-pin or 8-pin RJ45 10-PinDescription8-Pin 1 – – 2 DSR 1 3 RTS24 GND 35 TxD 46 RxD 57 DCD 68 CTS 79 DTR 8 10––NOTE1.

Xen虚拟机的安装

Xen虚拟机的安装虚拟化技术是云计算实现弹性计算的核⼼技术。

在构建云计算平台中，虚拟机的安装是基础。

常⽤的虚拟机⼯具很多，如VMware、XEN、KVM、Virtual PC等，这些⼯具使得⽤户可以在单台物理PC上（称为宿主机）虚拟出多个虚拟机VM(Virtual machine)，由于在每个VM上可以安装与宿主机不同的操作系统。

因⽽可以实现在⼀台物理PC上模拟出多台安装有不同操作系统的“PC”。

在云计算中，⽤户可以向云平台申请租⽤虚拟机，虚拟机的配置，如CPU的核数、主频，内存，存储容量等可以根据需要⾃⼰设定，并可动态修改。

现有虚拟机⼯具多⽀持这些功能，然⽽很多⼯具如VMware、XEN-Server等提供的免费测试⼯具多只提供GUI接⼝，⽤户只能通过图形界⾯实现虚拟机的创建和配置，⽆法实现动态的配置，以⾄于构建的云平台退化为不具有弹性的“虚拟机平台”。

Xen 是由剑桥⼤学开发的⼀款开放源代码虚拟机⼯具软件,⽀持虚拟机的各种配置和动态创建，最重要的是提供了丰富的⽤户管理接⼝。

本⽂根据马博⼠的安装⽅法，给出详细的安装流程，并对安装细节做进⼀步的补充说明。

NexentaStor 4.0.1的安装与初始化

NexentaStor 4.0.1的安装与初始化一、前言虚拟化环境需要存储进行测试，据说NexentaStor的IO性能要远高于Openfiler和FreeNAS，NexentaStor是基于OpenSolaris ZFS的NAS/SAN存储软件。

具有下面的特点：* 支持CIFS/NFS/iSCSI/FC等共享协议，提供NAS/SAN服务；* 提供几乎无限存储容量的支持；* 无需硬件RAID, 把硬盘扔到ZFS pool里，通过ZFS内置的RAIDZ提供冗余保护；* SSD硬盘，可以作为L2 Cache提高IOP，相当于自动分层；* 支持实时重复数据删除和压缩；* 支持ESXi 5.0的VAAI，通过了vmware/Xen的认证；* 支持存储的snapshot和clone；* 支持Block级别的同步/异步远程复制，实现远程灾备；* 有HA Plugin, 可以实现存储服务器的高可用。

NexentaStore Enterprise版本是收费的，下载网址如下所示：NexentaStore Community版本免费，但有12T存储容量的限制，下载网址如下所示：二、NexentaStor安装和初始化这里使用VMware虚拟机进行安装，虚拟机的硬件配置如下所示：其中10GB的硬盘用于安装NexentaStor操作系统，另外三块40GB的硬盘加入Pool。

首先创建虚拟机，由于该系统不能被识别所以得自定义，这里自定义系统为Solaris-64bit即可。

安装初始界面如下所示：选中第一块10GB的硬盘安装操作系统：重启后会要求输入注册码，注册码需要打开下面的网页申请：/corp/downloads/register-community-download 申请的画面如下所示：根据实际环境重新配置IP地址，如下所示：配置Web GUI的端口，如下所示：到此为止NexentaStor系统安装完毕。

然后登录Web界面进行初始化配置，刚才上面已经显示出了访问Web界面的IP地址及端口，即https://192.168.1.40:2000/。

Xen的配置和xend服务器的相关命令

Xen的配置和xend服务器的相关命令一：Xen的相关文件存放位置；xen安装后，文件放在什么地方了呢？主要放在以下几个目录；1）内核及xen自身存放于/boot安装有xen的操作系统下的/boot目录中，存放xen本身及支持xen的内核文件。

比如文件名带有xen0和xenU相关的文件；2）内核模块存放于/lib/modules内核模块包括虚拟平台支持xen的内核xen0的模块，及支持虚拟操作系统所用的xenU的模块，一般的情况下是在/lib/modules下有两个xen相关的目录存放。

一个是文件夹名带有xen0字样的，另一个是xenU字样的；3）xen的配置文件及守护程序的存放位置；一般的情况下，Xen的配置文件存放于/etc/xen目录。

比如xend-config.sxp是用于配置网络的，不过我们不必更改，用其默认的就能完成我们的需要。

xmexample1 xmexample2是两个示例性的配置文件。

我们在配置引导被虚拟的操作系统时，这两个文件可供参考；Xen的服务器xend和xendomains启动脚本，一般是位于/etc/init.d/目录中，也就是/etc/init.d/xend ；/etc/init.d/xend负责启动xend服务器，而/etc/init.d/xendomains负责第一个虚拟的系统及其它的Domains，也就是Domain 0 。

4）可执行命令存放于/usr/sbin[root@localhost ~]#ls /usr/sbin/xen*/usr/sbin/xen-bugtool /usr/sbin/xenconsoled /usr/sbin/xenmon.py /usr/sbin/xenstored/usr/sbin/xenbaked /usr/sbin/xend /usr/sbin/xenperf /usr/sbin/xentop[root@localhost ~]#ls /usr/sbin/xm二：Xen服务器的启动；xend服务器的启动/停止/重启/状态查询，请用下面的命令；[root@localhost ~]# /etc/init.d/xend start 启动xend，如果xend没有运行）[root@localhost ~]# /etc/init.d/xend stop 停止xend，如果xend正在运行）[root@localhost ~]# /etc/init.d/xend restart 重启正在运行的xend，如果xend没有运行，则启动[root@localhost ~]# /etc/init.d/xend status 查看xend状态启动xendomains 服务器的启动/停止/重启/状态查询，请用下面的命令；一般的情况下，xend服务器启动了，xendomains也会自动启动。

XENSERVER的安装和使用文档

XENSERVER的安装和使用一、XENSERVER的安装硬件环境要求：CPU：4GHz（X64）*4内存：最低4G硬盘空间：最低40GB准备一张XenServer6.0的安装光盘注意：以上是最低配置，实际情况请根据规划虚拟机数量来决定。

xen配置参数解释

xen配置参数解释# Kernel image file.kernel = "/usr/lib/xen/boot/hvmloader"设定该HVM虚拟机的内核镜像文件，默认是采用宿主机上/usr/lib/xen/boot/hvmloader这个来引导的。

# The domain build function. HVM domain uses 'hvm'.builder='hvm'设定虚拟域的建立方式，一个虚拟域对应了一个虚拟机，宿主机通过根域0来管理。

如果是HVM虚拟机的话，这项要设定为hvm。

# Initial memory allocation (in megabytes) for the new domain.# WARNING: Creating a domain with insufficient memory may cause out of emory errors. The domain needs enough memory to boot kernel and modules. Allocating less than 32MBs is not recommended.memory = 128设定虚拟机的占用的内存，如手册上说的，不建议设定低于32MB。

# Shadow pagetable memory for the domain, in MB.# Should be at least 2KB per MB of domain memory, plus a few MB per vcpu.shadow_memory = 8设定影内存？（这个术语的意思我还不了解，还烦请高手指点）这个配置项的默认值为8，单位MB。

虚拟机每多一个VCPU就应到增加一些。

# A name for your domain. All domains must have different names.name = "ExampleHVMDomain"设定虚拟机的域名实例。
