There are a few things to consider before installing DreamFactory Enterprise™ (DFE). The rest of this section will explain these considerations.
It goes without saying that if you are simply evaluating DFE, on a single instance, server and DNS planning are unnecessary. Skip ahead to the Installer Utility section.
DFE can be split out across multiple virtual machines or housed within a single one. The installer utility installs DFE as an **all-in-one** package. This requires a minimum of 7GB of RAM to function. 10-16GB is recommended.
DFE is a distributed system. Each component can operate and scale independently of each other. Conversely, the entire system can be contained on a single server. Therefore, the best server layout fully depends on your usage and needs. If you're just testing out DFE and not ready to deploy a production system, installing everything on a single server is the way to go (as it's mostly automated).
The servers required are:
- Application: Responsible for hosting/running the DFE Console, Dashboard, and/or the Reporting system.
- Database: Responsible for the databases of hosted instances
- Web: Responsible for (web) hosting the deployed instances
DFE operates each instance via virtual hosting on one or more web servers. As such, you must determine the fully qualified domain name of your DFE installation before installing. The system cannot be used fully until the DNS is in place. Generally, clients will create a new subdomain within their DNS domain. This is the recommended practice. Using a new domain will eliminate any issues with DNS cross-contamination if troubleshooting an issue.
There are three records that need to be created for the DFE installation. These are:
- console.sub.domain.com (A/CNAME)
- dashboard.sub.domain.com (A/CNAME)
- *.sub.domain.com (A/CNAME)
The first two are straightforward. These point to the DFE Console and Dashboard. These can be either
CNAME records. The final record is the wildcard entry. This allows all instances deployed on a server to share a single, common document root. For more information on how to set up your DNS with a wildcard record, please consult your DNS provider's documentation. Each provider has a different method for creating these records.
Please note that you cannot add a wildcard DNS entry to your local
/etc/hosts file. It does not work.
One of the features of the installation system is that several entries will be added to the installation system's
/etc/hosts file. Here is an /etc/hosts file after the installer has completed:
127.0.0.1 localhost ip-10-10-2-40 console console.local dashboard dashboard.local console.zone.domain.com dashboard.zone.domain.com zone.domain.com ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts
You'll notice after the `localhost` entry, there are seven additional entries which reference the new DFE installation. `zone` and `domain` are gathered via the installation utility and are used here for exemplary purposes.
To help with installation, a utility may be downloaded and run. This utility gathers the necessary information that then feeds into the main installation system, which is written using Puppet. PHP is required to run this utility. To use this utility you must first install the required packages, which differs depending on your operating system.
ubuntu@server:~ $ sudo apt-get update ubuntu@server:~ $ sudo apt-get upgrade ubuntu@server:~ $ sudo apt-get install php5 puppet git
ubuntu@server:~ $ sudo yum update ubuntu@server:~ $ sudo yum install php puppet git
Here's how to install the utility at a high level:
- Update the system packages and install pre-requisites
- Clone the utility's GitHub repository
- Update composer dependencies
- Start the installation utility
- Open your browser and enter the configuration settings
[email protected]:~$ sudo apt-get update [email protected]:~$ sudo apt-get upgrade [email protected]:~$ sudo apt-get install php5 puppet git [email protected]:~$ git clone https://github.com/dreamfactorysoftware/dfe-installer.git [email protected]:~$ cd dfe-installer ubuntu@server:~/dfe-installer$ php -S 0.0.0.0:8000 -t public/ ^C
At this point, fire up your browser and enter the public IP address of the installation system as follows:
8000 is used in the above example. You may use any port you prefer. However, you must ensure that whichever port you choose (including 8000!) is open to your browser from wherever the server is hosted. This is a temporary usage, so there will be no need for permanent port changes.
Here's what you should see in your browser (I've updated my hosts file with the public IP so I don't have to use the IP address).
This utility has all the installation options available. Once completed, the entries are written to a file called `.env-install` in the `storage` directory the installation root. This file is then read by the `./install.sh` script. This script does all the heavy lifting and completes the installation.
Once you've run the utility and created the installation environment file, you're ready to run the installation script.
To do this, from the root of the installation directory, run the following:
[email protected]:~/dfe-installer$ sudo ./install.sh
It can take up to 10 minutes to fully complete. This depends on your network connection and the server's specifications.
This is a complete walk through of the installation process with all information returned.

Output spooled to /tmp/dfe-installer.log [email protected]:~/dfe-installer$
All output of the installation utility is directed to a log file located at `/tmp/dfe-installer.log`. If there is an error, the log will detail the issue.
This log file is rotated each time `install.sh` is executed. The prior file is renamed to `/tmp/dfe-installer.log.` and a new empty file is created.
If you have already configured your DNS to point to the new installation, then you can skip this part entirely.
If you're setting up DFE on a single system, or with test/faux DNS entries, you *must* add these entries to your own `/etc/hosts` file.
First, you must locate the public, or accessible, IP address of the system upon which DFE is installed. Once you have that, simply add a line to the end of your `/etc/hosts` file:
public.ip.address.here console.zone.domain.com dashboard.zone.domain.com zone.domain.com test1.zone.domain.com test2.zone.domain.com
Replacing **zone**, **domain** with the zone and domain used when installing the system. The final two entries are to map instances you create to your faux DNS. They allow you to create two instances (test1 and test2). You can change the name to whatever you prefer or add more entries. It's up to you.
Here's an actual example:
18.104.22.168 console.dfe.3wipes.com dashboard.dfe.3wipes.com dfe.3wipes.com leela.dfe.3wipes.com bender.dfe.3wipes.com fry.dfe.3wipes.com
The order of the hosts in the list is not important. However, the fact that they are separated by spaces, is.
