Deploy .net core app to Ubuntu

Step 1 : Create Azure VM 

Ubuntu Server 20.04 LTS - Gen1

Standard B1s (1 vcpu, 1 GiB memory)

0.0104 USD/hr

Step 2 : Register Microsoft key and repository feed

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb Jump -O packages-microsoft-prod.deb

sudo dpkg -i packages-microsoft-prod.deb

Step 3 : Install Dot NET Core

-------.net sdk 3.1----------

sudo apt-get update; \

sudo apt-get install -y apt-transport-https && \

sudo apt-get update && \

sudo apt-get install -y dotnet-sdk-3.1

-------.net sdk 5----------

sudo apt-get update; \

  sudo apt-get install -y apt-transport-https && \

  sudo apt-get update && \

  sudo apt-get install -y dotnet-sdk-5.0

Step 4 : Install Nginx Web Server

sudo apt-get update

sudo apt-get install nginx

#Enable Nginx

sudo systemctl enable nginx

#Start Nginx

sudo systemctl start nginx

#check service status

sudo systemctl status nginx

#check service log

journalctl -u nginx.service

Step 5 : Deploying ASP.NET Core App

Create directory under nginx 

sudo mkdir /var/www/myapp

sudo chmod 777 /var/www/myapp

Step 6 : Clone git repository

git clone https://github.com/nageshajab/myapp.git

git clone will copy files into your home directory/ username

cd /home/nageshajab/myapp

Step 7 : Publish your code to server directory

run dotnet restore to get nuget libraries from server

dotnet restore

go to web directory to publish ur code to server directory

cd myApp.web

dotnet publish -c release --output /var/www/myapp

Step 8 : Configure a new website in nginx

Open nginx config file

sudo nano /etc/nginx/sites-available/default




add this block to opened file

server {
    listen 80;

    root /var/www/myapp;
    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 $http_host;
  proxy_cache_bypass $http_upgrade;
  }
}

Save file & exit

• Save the modified default file press (Ctrl + O) and hit the enter
• To exit the nano editor press (Ctrl + x) it will ask you to exit write Y and hit the enter on your keyboard.

We have replaced content of the default server block file on Nginx so we need to reload changes that we have made before we running the following command.

sudo nginx -s reload

Step 9 : Create ubuntu unit service to host .net core app

Create a service definition and put below code in it. For creating/ stopping / starting/ edition/ enable/ disable services refer - How To Use Systemctl to Manage Systemd Services and Units | DigitalOcean

[Unit]

Description=Asp.NET Web App now is running on Ubuntu

[Service]

WorkingDirectory=/var/www/myapp

ExecStart=/usr/bin/dotnet /var/www/myapp/myApp.dll

Restart=always

# Restart service after 10 seconds if the dotnet service crashes:

RestartSec=10

KillSignal=SIGINT

SyslogIdentifier=myapponlinux-log

Environment=ASPNETCORE_ENVIRONMENT=Production

Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

[Install]

WantedBy=multi-user.target

Step  9 : Copy database backup file to server
