XenApp-XenDesktop7.6是一款用于虚拟化桌面和应用程序的软件解决方案,能够为用户提供灵活的工作环境,实现随时随地访问企业资源的需求。在进行XenApp-XenDesktop7.6的安装配置过程中,首先需要对部署环境进行规划和准备。根据实际需求,在XenCenter上创建了三台虚拟服务器,分别是AD服务器、XenApp服务器和VDA服务器。其中,AD服务器运行Windows 2012R2操作系统,计算机名为test1;XenApp服务器也运行Windows 2012R2操作系统,计算机名为test2;VDA服务器是用于测试的系统,同样也是运行Windows 2012R2操作系统,计算机名为test3。另外,根据实际应用情况,对硬件配置也有一定要求,要求CPU为8核以上,内存为8G到16G以上,硬盘空间为1T。在软件准备方面,需要准备XenApp-XenDesktop7.6的安装文件,并为这三台虚拟服务器分配IP地址,分别为test1的IP为192.168.100.1、test2的IP为192.168.100.2、test3的IP为192.168.100.3。 在虚拟服务器创建完成后,需要对后两台虚拟机进行重新封装的处理,具体操作如下:首先,运行命令提示符(cmd);其次,进入C盘下的`Windows\System32`目录;然后,运行`sysprep /oobe /generalize /reboot`命令进行系统重新封装。这样,当虚拟机重启后,重新封装的操作便生效了。 总的来说,在XenApp-XenDesktop7.6的安装配置过程中,不仅需要对部署环境进行规划和准备,还需要对硬件和软件进行充分准备,以确保整个部署过程的顺利进行。通过以上所述的操作步骤和要求,能够帮助用户更好地进行XenApp-XenDesktop7.6的部署和配置,从而为企业的IT运维管理提供更加高效、灵活的解决方案。

• Citrix XenApp5.0培训 • 主讲:jaffee • XenApp 5.0 server • Farm:  Citrix XenApp server uses server farms to organize and manage servers.  load balance user sessions  manage the entire set of Citrix XenApp servers from a single point  Users can connect directly to applications, without needing to know the location of an individual server  reconnect to another server and receive the same environment as before when the sever crashs • TwoTechnology • ICA: Independent Computing Architecture  At its heart, ICA intercepts and transports screens from the server that a published application runs on to the client PC It then takes the user’s return input and transmits it back to the server for processing  ICA uses port 1494 by default, or 2598  What Is Actually Being Sent between an ICA Client and a XenApp Server?  ICA works by essentially piggybacking on top of other protocols such as TCP/IP、 UDP and IPX/SPX  The ICA client also can cache frequently used graphics such as icons and menu items • Citrix Session States • TwoTechnology • Independent Management Architecture(IMA)  It is a centralized management subsystem that allows you to define and control the elements of your server farm  Server-to-server communication occurs over TCP port 2512, PMC-to-server communication occurs over TCP port 2513  In essence, it is the technology that allows you to group servers • Citrix Datastore • S tore information within the Citrix XenApp server farm that remains relatively static. Items such as published applications, administrator names and permissions, and server listings • A single datastore is used for each individual server farm • T he datastore can reside on a Citrix XenApp server or on a dedicated host • Citrix XenApp supports Microsoft Access, MS SQL Express, MS SQL Server, IBM DB2 • Disk space requirements for the datastore are approximately 20 MB for every 100 servers • Datastore Usage • Access mode: direct mode and indirect mode  Direct mode :Microsoft SQL or Oracle  Indirect mod:Microsoft Access With the availability of three solutions for the datastore, how do you tell which one best fits your environment? • LHC :Local Host Cache • The LHC is a partial copy of the datastore database that every XenApp server maintains locally to the server itself  Continue running based on the configuration that is last received from the datastore  performance • Data Collector • Manage information that changes frequently, such as current sessions, active licenses, and server and application load values within a zone • The data collector acts as the central point of information when clients connect to your server farm • Every zone with a server farm consists of one active data collector • Bandwidth Requirements for a Server Farm • Server-to-Data-Store Communication KB = 275 + (5 * Servers) + (0.5 * Apps) + (92 * Print Drivers) A farm with 4 severs,12 published applications, and 6 print drivers KB = 275 + (5 * 4) + (0.5 * 12) + (92 * 6) KB = 275 + (20) + (6) + (552) KB = 275 + (578) KB = 853 • Bandwidth Requirements for a Server Farm • Data Collector Communication Bytes = 11000 + (1000 * Con) + (600 * Discon) + (350 * Apps) A server with 20 connected sessions, four disconnected sessions, and nine published applications Bytes = 11,000 + (1,000 * 20) + (600 * 4) + (350 * 9) Bytes = 11,000 + (20,000) + (2400) + (3150) Bytes = 11,000 + (25,550) Bytes = 36,550 or 36.55 KB • Listener Ports • Listener ports work in cooperation with internal system components and client connections • The listener service monitors new client connections and manages the idle sessions. • CPS4.5 vs XenApp 5.0 XenApp 2008/1 Presentation Server MetaFrame WinFrame Note: Xen App5.0:windows server 2003*/2008* CPS4.5 :windows server 2003 * • XenApp Server Editions • XenApp Edition Components • XenApp 5.0 Server License Server • XenApp server will not accept user connections until it can contact a License Server • Citrix provides a 96-hour initial grace period that will allow up to two users to connect while unable to connect to a License Server • Citrix XenApp client • the XenApp Plugin,the XenApp Web Plugin, and Program Neighborhood • Microsoft’s System Center Configuration Manager (SCCM) IBM’s Tivoli Provisioning Manager are used to centralize deployment and maintain software • the XenApp Plugin • Launch applications from her Start | Programs menu • Step:  publishing an application to the XenApp farm  To launch an application from the System Tray icon  DISCONNECT, RECONNECT, AND LOG OFF OF AN APPLICATION WITH THE CONNECTION CENTER • the Citrix XenApp Web Plugin • The Web Plugin is the simplest of the Windows clients and does not allow for as much interaction or configuration. • often be deployed in scenarios where machines are older, slower, or not in need of additional configuration options such as the Start menu and desktop shortcuts • Program Neighborhood • Oldest ICA client version but the most advanced • Many settings are available to users as check boxes or radio buttons • good in the sense that users can enable a setting such as Local Text Echo for just their client if they are a fast typist and the latency of the session cannot keep up; and bad when a user can delete his application set and can’t get connected • the only client that connects to applications on a Citrix server that have not been published for access by users
