Redhat和CentOS的安装和设置方式完全一样，因为Redhat yum源不好设置，在测试的过程中都是以CentOS来代替。以下安装是以LVDA 2203LTSR + CentOS 7.9版本演示安装过程，在安装的过程中保证VM是可以连接公网的，因为需要下载依赖包。
1.离线安装.Net Core Runtime
LVDA2203需要的是.Net Core Runtime 6.x版本：https://dotnet.microsoft.com/download/dotnet/6.0
创建/opt/dotnet目录，并解压到其中
sudo mkdir /opt/dotnet sudo tar -C /opt/dotnet/ -xvf dotnet-runtime-6.0.5-linux-x64.tar.gz
2.安装VDA包
sudo yum localinstall -y XenDesktopVDA-22.03.0.18-1.el7_x.x86_64.rpm
3.运行ctxinstall.sh脚本
[root@qccentos ~]# sudo /opt/Citrix/VDA/sbin/ctxinstall.sh ctxinstall.sh sets up Linux VDA running environment, which includes the automatic installation of the necessary packages and changes to the configuration files. [Warning]The current shell will be hung for a while to install packages. You can monitor the execution status using command 'tail -f /var/log/ctxinstall.log' in another shell. ****System check starts now. Step 1: The platform is 64-bit Linux [Pass].

Value not set. Dotnet Core runtime environment is needed to run Linux VDA. Please specify Dotnet Core binary path here. If not specified, Linux VDA will use /usr/bin as default. DotNet Core Runtime Path: /opt/dotnet Checking CTX_XDL_SUPPORT_DDC_AS_CNAME... Value not set. The Virtual Delivery Agent supports specifying a Delivery Controller name using a DNS CNAME record. Do you want to enable support for DNS CNAME records? (y/n) [n]: //Delivery Controller地址: 这里要把所有的DDC FQDN都填上，否则会发生点击桌面图标时VDA从注册变成未注册状态问题，多个DDC中间以空格隔开 Checking CTX_XDL_DDC_LIST... Value not set. The Virtual Delivery Agent requires a space-separated list of Delivery Controller Fully Qualified Domain Names (FQDNs) to use for registering with a Delivery Controller. Please provide the FQDN of at least one Delivery Controller: ddc01.qicai.lab ddc02.qicia.lab Checking CTX_XDL_VDA_PORT... Value not set. The Virtual Delivery Agent by default communicates with Delivery Controllers using TCP/IP port 80. Please provide the TCP/IP port the Virtual Delivery Agent service (ctxvda) should use to communicate with a Delivery Controller [80]: Checking CTX_XDL_REGISTER_SERVICE... Value not set. The Linux VDA services support starting during boot. Do you want to register these services to start on boot? (y/n) [y]: Checking CTX_XDL_ADD_FIREWALL_RULES... Value not set. The Linux VDA services require incoming network connections to be allowed through the system firewall. Do you want to automatically open the required ports (by default ports 80, 1494, 2598, 8008 and 6001~6099) in the system firewall for the Linux VDA? (y/n) [y]: //是否开启3D pro，如果选择了3D Pro模式，则只能发布单会话VDI Checking CTX_XDL_HDX_3D_PRO... Value not set. Linux VDA supports HDX 3D Pro, a set of graphics acceleration technologies designed to optimize the virtualization of rich graphics applications. HDX 3D Pro requires a compatible NVIDIA Grid graphics card to be installed. If HDX 3D Pro is selected the Virtual Delivery Agent will be configured for VDI desktops (single-session) mode. Do you want to enable HDX 3D Pro? (y/n) [n]: //是否开启VDI 模式（单会话）: VDI模式即单会话模式，类似Windows 10桌面；如果不开启VDI模式，则为多会话模式，类似Windows server 2016共享桌面。在安装Ubuntu OS镜像时,无论是安装的Ubuntu Server还是Desktop，最终用户的使用方式跟是否开启VDI模式有关。 Checking CTX_XDL_VDI_MODE... Value not set. Linux VDA supports delivery of hosted shared desktops (multi-session) or VDI desktops (single-session). Do you want to enable VDI desktops (single session) mode? (y/n) [n]: y Checking CTX_XDL_SITE_NAME... Value not set. The Virtual Delivery Agent discovers LDAP servers using DNS, querying for LDAP service records. To limit the DNS search results to a local site, a DNS site name may be specified. If required, please specify a local DNS site name. [<none>]: Checking CTX_XDL_LDAP_LIST... Value not set. The Virtual Delivery Agent by default queries DNS to discover LDAP servers, however if DNS is unable to provide LDAP service records, you may provide a space-separated list of LDAP Fully Qualified Domain Names (FQDNs) with LDAP port (e.g. ad1.mycompany.com:389). If required, please provide the FQDN:port of at least one LDAP server. [<none>]: Checking CTX_XDL_SEARCH_BASE... Value not set. The Virtual Delivery Agent by default queries LDAP using a search base set to the root of the Active Directory Domain (e.g. DC=mycompany,DC=com), however to improve search performance, a search base may be specified (e.g. OU=VDI,DC=mycompany,DC=com). If required, please provide an LDAP search base. [<none>]: Checking CTX_XDL_FAS_LIST... Value not set. The Federated Authentication Service (FAS) servers are configured through AD Group Policy. But because the Linux VDA does not support AD Group Policy, you can provide a semicolon-separated list of FAS servers instead. Caution 1: The sequence must be the same as configured in AD Group Policy. Caution 2: If any server address is removed, you must fill its blank with the '<none>' string and keep the index of server addresses without any changes. If required, please specify the list of FAS servers (e.g., fasserver.company.com). [<none>]: Checking CTX_XDL_START_SERVICE... Value not set. The Linux VDA services may be started after configuration is complete. Do you want to start these services once configuration is complete? (y/n) [y]: Here are your inputs: .NET Core Runtime Path: /opt/dotnet Enable DNS CNAME records: n The FQDN of Delivery Controller: ddc01.qicia.lab ddc02.qicai.lab The TCP/IP port that ctxvda service uses to communicate with Delivery Controller: 80 Register Linux VDA services to start on boot: y Automatically open the required firewall ports (ports 80 and 1494 by default): y Enable HDX 3D Pro: n Enable VDA desktops (single session) mode: y Specify a local DNS site name: <none> The FQDN:port of LDAP server.: <none> Provide an LDAP search base: <none> List of FAS servers: <none> Start Linux VDA services once configuration is complete: y Are all inputs correct? y|n [y] Step 2: Configure host name.
