- A standard user account with sudo privileges
- The latest stable .NET runtime installed on the server
- An existing ASP.NET Core application
4.2 Publish the ASP.NET Core Application
Configure the ASP.NET Core application for a framework-dependent deployment. This means that the application relies on the .NET runtime installed on the server.
Run the following command from the development environment to package the application into a directory:
dotnet publish --configuration ReleaseThis command creates a publish directory containing the application files.
4.3 Copy the Application to the Linux Server
Use a tool like SCP or SFTP to copy the contents of the publish directory to the Linux server. A common location for web applications is the /var/www directory. For example:
scp -r bin/Release/net8.0/publish user@server_ip:/var/www/myapp4.4 Install and Configure Nginx as a Reverse Proxy
Nginx is a popular choice for a reverse proxy server. Install it using the package manager for the chosen Linux distribution. For example, on Ubuntu:
sudo apt update
sudo apt install nginxAfter installation, configure Nginx to forward requests to the ASP.NET Core application. Edit the default Nginx configuration file:
sudo nano /etc/nginx/sites-available/defaultReplace the contents of the file with the following configuration:
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}This configuration tells Nginx to listen on port 80 and forward all requests to http://localhost:5000, where the ASP.NET Core application will be running.
Test the Nginx configuration and restart the Nginx service:
sudo nginx -t
sudo systemctl restart nginx4.5 Configure Systemd to Manage the ASP.NET Core Application
Systemd is used to manage the ASP.NET Core application as a service. Create a service file for the application:
sudo nano /etc/systemd/system/myapp.serviceAdd the following configuration to the service file:
[Unit]
Description=My ASP.NET Core Application
[Service]
WorkingDirectory=/var/www/myapp
ExecStart=/usr/bin/dotnet /var/www/myapp/myapp.dll
Restart=always
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=myapp
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production
[Install]
WantedBy=multi-user.targetReplace /var/www/myapp with the actual path to the application directory and myapp.dll with the name of the application’s DLL file. The User=www-data line specifies the user that the application will run as. Ensure that this user has the necessary permissions to access the application files.
Enable and start the service:
sudo systemctl enable myapp.service
sudo systemctl start myapp.serviceCheck the status of the service to ensure that it is running correctly:
sudo systemctl status myapp.service4.6 Configure Firewall
Configure the firewall to allow traffic on ports 80 (HTTP) and 443 (HTTPS). For example, using ufw on Ubuntu:
sudo ufw allow 80
sudo ufw allow 443
sudo ufw enable4.7 Test the Application
Open a web browser and navigate to the server’s IP address or domain name. The ASP.NET Core application should be running and accessible.
