sudo nano /etc/nginx/sites-available/sites.com

server {
    listen        80;
    server_name   ;
    location / {
        proxy_pass         http://localhost:5000;

        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;

include /etc/nginx/sites-enabled/*;

http{
    ...
    include /etc/nginx/sites-available/sites.com;
}

sudo service nginx restart

Create service

sudo nano /etc/systemd/system/dotnet-project-name.service

[Unit]
Description=My application service

[Service]
WorkingDirectory=/var/www/
ExecStart=/usr/bin/dotnet /var/www//.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

[Install]
WantedBy=multi-user.target

In my case,

[Unit]
Description=My application service

[Service]
WorkingDirectory=/var/www/oguzhanabali-dev-demo-web
ExecStart=/usr/bin/dotnet /var/www/driesdeboosere-dev-demo-web/Oguzhanabali.Dev.Demo.Web.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=oguzhanabali-dev-demo-web
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

[Install]
WantedBy=multi-user.target

Permission access to folders,

 

sudo chown -R root:root /var/www/
sudo setfacl -R -d -m u:root:rwx,g:root:rwx,o::r /var/www/

sudo service oguzhanabali-dev-demo-web start

sudo systemctl | grep oguzhanabali-dev-demo-web

That’s it! Now your web server will keep running your ASP.NET Core app, even if you exit the server.
