I have a Discord bot built with C# that I want to deploy on my Debian VPS. I’m pretty new to Linux systems and feeling lost about the deployment process.
I already got Mono installed on the server since I read somewhere that it’s required for running C# applications on Linux. However, I’m stuck on the actual steps to get my bot running.
Could someone walk me through the process? I’m not very experienced with coding and I built this bot using Visual Studio 2015. Any detailed instructions would be really helpful since I don’t want to mess up my VPS setup.
What files do I need to upload? How do I actually execute the bot? Do I need any additional dependencies or configurations?
Skip the Mono hassle entirely. I’ve fought with C# bot deployments way too many times.
You need proper automation for this. Forget wrestling with server configs, dependencies, and keeping bots alive - set up a workflow that handles it all.
I automate all my Discord bots now. Trigger bot logic through webhooks, handle Discord API calls, manage database connections, auto-restart when things break. No more SSH sessions or wondering if your VPS died.
Best part? Keep your C# logic but wrap it in automation that handles infrastructure. Discord events become triggers, bot responses become actions, everything runs reliably in the cloud.
Way cleaner than fighting Linux permissions and Mono compatibility. Check out Latenode for this setup: https://latenode.com
Since you’re on VS 2015, first check which Discord library you’re using - some older versions don’t play nice with Discord’s current API. I hit this same issue when migrating an old bot. For deployment, set up a systemd service to keep your bot running. Once you’ve got it working manually with mono, create /etc/systemd/system/yourbot.service with the right working directory and restart policies. This stops it from dying when you close SSH. Also check your connection strings and file paths - any hardcoded Windows paths like C:\ will break on Linux. Most deployment headaches I’ve seen are config issues, not Mono problems.
since you’ve got mono, check it is working with mono --version. if ur bot does anything with images, install libgdiplus too; run sudo apt install libmono-system-drawing4.0-cil since bots can crash without it sometimes.
honestly mono might give you headaches - consider switching to .NET core instead if possible. much easier deployment and better performnce on linux. just dotnet publish your project then upload the output folder and run with dotnet yourbot.dll
VS 2015 likely means you’re targeting an older .NET Framework. It’s crucial to check your project properties since Mono can be specific about version compatibility, and you may require additional packages on your Debian setup.
Be sure to upload your whole bin/Debug or bin/Release folder, including configuration files like appsettings.json or your bot tokens, as I’ve encountered issues with bots crashing due to missing configurations.
Before configuring any background services, manually test your bot using mono YourBot.exe. If it fails to run, consult the Mono logs for insights—they can effectively pinpoint any missing dependencies.
You’ve got Mono already, so you’re good to go. Build your project in Visual Studio and grab everything from the bin folder - the exe and all those dll files need to go up to your VPS. Just SCP them over or use your hosting panel’s file manager.
Make sure to chmod +x your executable, then run mono YourBotName.exe from terminal. You’ll want to set up a service or use screen/tmux so it doesn’t die when you disconnect from SSH.
One heads up - Linux is case-sensitive, so double-check your Discord token path and config file paths. That’s usually what trips people up coming from Windows.
Had the same issue moving my bot from Windows dev to Linux production. Here’s what fixed it for me: use environment variables for your bot token instead of hardcoding it in config files. Linux file permissions will expose your token if you’re not careful with uploads. Write a simple bash script that exports your token as an environment variable, then change your C# code to use Environment.GetEnvironmentVariable instead of reading config files. Also, Mono gets picky about SSL certificates with Discord API calls - if you hit certificate errors, install the ca-certificates-mono package. Deployment’s pretty straightforward once your environment’s set up right, but these security and certificate issues will get you if you don’t fix them first.
