FlexSim's Webserver is a query-driven manager and communication interface for FlexSim. It allows you to run FlexSim models through a web browser like Google Chrome, FireFox, Internet Explorer, etc. Since the FlexSim Web Server is a basic service to allow FlexSim to be served to a browser, you may decide you want a way to proxy to this service through a full service web server that you can control security and authentication through.
This guide will walk you through proxying to the FlexSim Web Server through Nginx web server.
Install the FlexSim Web Server Program
Download and install the FlexSim Web Server from https://account.flexsim.com Edit C:\Program Files (x86)\FlexSim Web Server\flexsim webserver configuration.txt Change the port from 80 to 8080 Start the FlexSim Web Server by double clicking flexsimserver.bat Test the server by going to http://127.0.01:8080 It should look like this:
Install Nginx Reverse Proxy
From a browser, visit http://nginx.org/en/download.html Download latest stable release for Windows Extract the downloaded nginx-<version>.zip Rename the unzipped nginx-<version> folder to nginx Copy the nginx folder to C:\ Double click the C:\nginx\nginx.exe file to launch Nginx Test Nginx by going to http://127.0.0.1 It should look like this:
Configure Nginx to proxy to the FlexSim Web Server
Open C:\nginx\conf\nginx.conf in a text editor Find the section that says:
location / {
root html;
index index.html index.htm;
}
Edit out the root and index directives and add a proxy_pass directive so it appears like this:
location / {
proxy_pass http://127.0.0.1:8080;
#root html;
#index index.html index.htm;
}
Save the nginx.conf file
Reload Nginx to Apply the Changes
Open a command line window by pressing Windows+R to open "Run" box. Type "cmd" and then click "OK" From the command line windows, type the following to change to the nginx directory:
C:\nginx>cd C:\nginx and press enter
Now, type the following to reload Nginx:
C:\nginx>nginx -s reload
Test the FlexSim Web Server Being Proxied by Nginx
From a browser window again go to http://127.0.0.1 You should now see the FlexSim Web Server interface proxied through Nginx
Now that you have the FlexSim Web Server proxied through Nginx, you may decide you want to configure Nginx to handle security, authentication and customization. Since this is out of the scope of this guide, you can find details on the Internet that can guide you to setting these customizations up.
