Setting up your web API services using IIS can feel a bit overwhelming at first, but honestly, once you get the hang of it, it’s super straightforward. I can share my experience and walk you through the process so you can get your API up and running without too much fuss.
First, you’ll want to make sure that your development environment is set up properly. I usually work on Windows, so the first step is ensuring that IIS is installed and enabled. If it’s not already running on your machine, you can easily get it from the control panel. Just hop into "Programs and Features," then click on "Turn Windows features on or off," and tick that box for Internet Information Services. You might also want to check the features under IIS, like the Web Management Tools and World Wide Web Services, especially if you think you’ll need them later.
Once you have everything set up, you can get your API project ready. I typically use ASP.NET Core for my APIs, since it's lightweight and can suit a lot of different use cases. You probably already have your project built and tested locally, which is great because that means you're almost there! Just make sure your API is ready to be published.
Publishing an API is usually a straightforward process. In Visual Studio, you can right-click on your project and select Publish. You’ll see a bunch of options, but for now, let’s choose the Folder option since we want to deploy it on IIS. Pick a folder path where you want your files to go. Once that’s done, you can hit Publish, and Visual Studio takes care of the rest. It compiles everything, packages it, and throws it in your designated folder.
Now, let’s move on to configuring IIS. Open up the IIS Manager – it’s usually found in the Administrative Tools in the Control Panel. You’ll see your machine’s name on the left side. This is where you can manage all your sites. Right-click on "Sites" and choose "Add Website," which opens up a new window.
In that window, you’ll need to fill in some info. The site name can be anything you want, say "MyApiService". Next, you’ll browse and select the physical path where your published API files are stored. This is the path you selected during the Publish step. After that, you’ll set up a port. By default, you can use port 80 if you don’t have anything else on that. Just make sure it’s not already in use, or you can choose another port like 8080 – it’s totally up to you.
Next, it’s critically important to set the binding type to "http" or "https," depending on whether you plan to run the service securely or not. For testing purposes, http is usually fine, but remember, it’s best practice to use https for anything production-related. After setting that up, you can hit OK, and just like that, you’ve created your site in IIS!
Now comes the part where I usually run into some issues at first: setting the correct application pool. In IIS, each site runs under an application pool that handles the execution environment for a web application. By default, your site runs under the "DefaultAppPool," but sometimes it’s better to create a new one, especially for .NET Core apps. Right-click on "Application Pools" and select "Add Application Pool." Just name it something relevant, maybe "MyApiAppPool," and set the .NET CLR version to "No Managed Code."
This is crucial because ASP.NET Core runs in its own environment and does not depend on the full .NET Framework. Once that’s done, you can go back to your site, right-click on it, and choose "Edit Application" to assign it to your newly created application pool.
After you’ve done that, it’s time for testing! I usually open up a browser and type in either "http://localhost:YourPort/api/values", or whatever your endpoint is. If everything is set up correctly, you should see your API responding with data, or at least not throwing any errors.
If you’re getting an error, it could be a few things. I often check the logs at this point. Make sure that you have logging enabled in your app. You can also check the Event Viewer in Windows. Errors can often pop up there, especially if IIS is trying to run things and has no idea what to do. This part can be a bit tricky, but with patience, I’ve usually found the culprit.
I also like to check the permissions on the folder where I published my API. IIS runs under a specific user account, so I’d make sure that the IIS_IUSRS group has read and execute permissions on that folder. Sometimes all it takes is that little permission tweak, and your API starts behaving properly.
Once everything is working fine on your local machine, it might be time to think about deploying it on a production server. I tend to replicate the same process I just described, but there are other factors to consider, like setting up a database connection and configuring the firewall settings. Always remember to check that the server allows traffic through your API’s port.
Another tip that’s always helped me is to enable CORS if your API is meant to be accessed by a client-side application running in a different domain. CORS needs to be set up in the middleware as part of your API. In your Startup.cs file, you can add services.AddCors to the ConfigureServices method, and then configure the policy accordingly.
Also, keep in mind that once your API is running, you might want to monitor its performance or set up some logging tools to track usage. There are many third-party services out there that can provide insights into how well your API is performing, which can be super helpful for ongoing maintenance and improvement.
After doing all of this, you’ve set up your Web API service on IIS and have a solid foundation for any future projects you want to tackle. It's incredibly satisfying to see it all come together, knowing you've got a working service that you can build on.
Trust me, with hands-on practice, you’ll find that hosting and managing APIs through IIS gets easier each time. I hope this gives you a clear roadmap, but I’m here if you have any questions or need clarification on any part of the process!
I hope you found my post useful. By the way, do you have a good Windows Server backup solution in place? In this post I explain how to back up Windows Server properly.
