After you have installed and configured the Trifacta® platform and verified operations, you may optionally configure an SSL certificate to secure connections to the web application of the platform.
- A valid SSL certificate for the FQDN where the Trifacta application is hosted
- Root access to the Trifacta server
- Trifacta platform is up and running
There are two separate Nginx services on the server: one service for internal application use, and one service that functions as a proxy between users and the Trifacta application. To install the SSL certificate, all configuration are applied to the proxy process only.
Log into the Trifacta server as the centos user. Switch to the root user:
Enable the proxy nginx service so that it starts on boot:
Create a folder for the private key and limit access to it:
Copy the following files to the server. If you copy and paste the content, please ensure that you do not miss characters or insert unwanted characters.
.keyfile should go into the
The .crt file and the CA bundle/intermediate certificate bundle should go into the
NOTE: The delivery name and format of these files varies by provider. Please verify with your provider's documentation if this is unclear.
Your certificate and the intermediate/authority certificate must be combined into one file for nginx. Here is an example of how to combine them together:
Update the permissions on these files. Modify the following filenames as necessary:
Use the following commands to deploy the example SSL configuration file provided on the server:
NOTE: Below, some values are too long for a single line. Single lines that overflow to additional lines are marked with a
\. The backslash should not be included if the line is used as input.
Edit the following file:
Please make the following modifications:
FQDN of the host, which must match the SSL certificate's Common Name
Path to the file of the certificate bundle that you created on the server. This value may not require modification.
Path to the .key file on the server.
Save the file.
To apply the new configuration, start or restart the nginx service:
Modify listening port for Trifacta platform
If you have changed the listening port as part of the above configuration change, then the
proxy.port setting in Trifacta platform configuration must be updated.
Add secure HTTP headers
If you have enabled SSL on the platform, you can optionally insert the following additional headers to all requests to the Trifacta node:
|X-XSS-Protection||HTTP and HTTPS|
|X-Frame-Options||HTTP and HTTPS|
NOTE: SSL must be enabled to apply these security headers.
To add these headers to all requests, please apply the following change:
- You can apply this change through the Admin Settings Page (recommended) or
trifacta-conf.json. For more information, see Platform Configuration Methods.
Locate the following setting and change its value to
- Save your changes and restart the platform.
Enable secure cookies
If you have enabled SSL on the platform, you can optionally enable the use of secure cookies.
NOTE: SSL must be enabled.
Problem - SELinux blocks proxy service from communicating with internal app service
If the Trifacta platform is installed on SELinux, the operating system blocks communications between the service that manages the proxy between users and the application and the service that manages internal application communications.
To determine if this problem is present, execute the following command:
The problem is present if an error similar to the following is returned:
For more information on this issue, see https://www.nginx.com/blog/using-nginx-plus-with-selinux.
The solution is to enable the following network connection through the operating system:
Restart the platform.
