1. ColdFusion 9 Installation How-To

   Step 1: Auto Run your CD or Double Click the installation file, you will see this screen as it extracts the compressed files.

2. Introduction

   Welcome to the installation Wizard of Adobe ColdFusion 9, Adobe recommends that you exit from all running applications before proceeding. This is more then a recommendation, some applications may cause the installation to fail.

3. License Agreement
   

   Installation and Use of Adobe ColdFusion 9 Requires Acceptance of the Following License Agreement. Accept the terms or end installation process now.

4. Install Type
   

   If you do not have a serial number, select either 30-day trial or Developer Edition. NOTE: Developer Edition only allows 2 CPU's connected at a time. Your SQL server and if your a black hat, the Reverse Proxy HTML Wrapper. If your a White Hat, then it will be your workstation computer.

5. Installer Configuration

   Your choice; Server Configuration, Enterprise Multiserver configuration & J2EE Configuration. In my step-by-step example I am using the Server Configuration. If you expect server growth I would recommend Enterprise Multiserver configuration.

6. Sub-Component Installation
   

   Select the subcomponents to install: Coldfusion 9 ODBC Services, Coldfusion 8 Search Services, ColdFusion 9 Solr Services, .NET Integration Services, ColdFusion 9 Docu

7. Select Installation Directory
   

   Select the directory where you want to install Adobe ColdFusion 9. The default directory is C:\ColdFusion9

8. Configure Web Servers / Websites
   

   If IIS is NOT installed on your system the "All IIS websites" will not be an option. You will however have the option for Apache and SUN's version of a web server. Or if you are installing the Developer Edition you have the option for a built in web server. I recommend Apache/Linux install. However, In my installation I will be using IIS 7 on Windows Server 2008 Standard. 

9. Choose Adobe ColdFusion 9 Administrator Location

   Select the location of the web root for Adobe ColdFusion 9. This is where the installer places the Adobe ColdFusion 9 Administrator. This directory must be the web root for one of the websites to be configured for use with Adobe ColdFusion 9. If configuring an IIS website, you must set scripts to be executable.  Default directory: C:\inetpub\wwwroot

10. Administrator Password
    

    Enter the password that you will use to restrict access to the ColdFusion Administrator. *This field is required.

11. Enable RDS
    

    The ColdFusion Remote Development Servers (RDS) lets developers using Adobe tools remotely connect to this server for development purposes. RDS is required for Line Debugging, Report Builder, andDreamweaver Extensions.  YOU WILL WANT THIS. Unless this is a production server and you have already debugged and tested your applications.

12. Pre-installation Summary

    Review the installation options, Type, Licensing, Directories and Server Information.
