Before going through these instructions, ensure you have created your Citrix IMA database, have decided what farm name and zone name you are going to use if this is going to be the first Xenapp server within the farm.
Personally, i would setup in the following order, just so you have an idea of what needs to be done:
1) SQL server – create IMA database
2) Setup up licensing on an existing or dedicated server (probably existing). This role can be installed by launching setup from the Xenapp media, installing common components and then installing licensing. Import your license you purchased from Citrix.
3) Setup a dedicated server for ZDC
4) Install first Xenapp server, the first server will always be selected as most prefered for ZDC. This can be changed later by right clicking your zone within your farm (via app centre)
5) Install additional Xenapp servers if required and add to existing farm
6) Install web interface on dedicated server. This can be done by launching setup and installing common components
1) Launch Xenapp 6.5 setup from your media
2) If prompted click yes to installing .net SP
3) Click Add server roles
4) On the next screen, select your Xenapp edition. Platinum, Enterprise or Advanced, depends on what you have purchased.
5) Accept the agreement and click next
6) Click Xenapp and next (Assuming it’s just a Xenapp server)
7) On the next screen, click the required components. The top three are ticked by default. The optional component is the XML service IIS integration.
The Citrix XML service is a component of Citrix XenApp and XenDesktop that is used to total available resources and provide secure tickets for users who use the WebInterface or CloudGateway. The Citrix XML service is mainly used to provide users access to their applications and desktops via a web portal, leveraging the services of WebInterface.
See screen shot below.
8) Review prerequistes and click next
9) Click Install and finish when prompted
10) Click reboot
11) After server reboots, logon and launch setup again, click Install Xenapp Server and the below screen will appear giving you the option to resume the install. Click resume install
12) Click install and finish when done
13) Click specify licensing and enter your licensing server details. Test connection. If you have not yet setup a licensing server, click configure later. You can enter licensing server later by launching setup again.
14) On the next screen, select your licensing model. Most likely going to be Xenapp as the other two are Xendesktop.
15) On the next screen click configure
16) Select your option, if this is a new install and your first Xenapp server, you will need to create a new farm.
17) If it’s a new farm enter your chosen farm name. (We will continue with adding the server to a farm which already exists). Click add this server to an existing farm and then add server to an Existing Microsoft SQL server database.
18) Enter your SQL server name and IMA database and enter your service account and password. Test the connection. If it fails, your windows firewall on your SQL server may be the cause.
19) Leave the default of Allow shadowing of user sessions on this server (depends on if this is a requirement). Click next
20) Click use custom zone name and enter the zone name if it already exists, or enter a new one. The newly created zone name will need to be used on all new xenapp servers added to the farm unless you have different zones.
21) On the remote desktop users tab, you could leave as default but you may want to untick if you control this through group policy.
22) Click next and finish
You may wish to install the latest Citrix rollup pack.
Please note, this procedure was created whilst installing Xenapp on a test environment. Please carry out testing and further checks.
