As we all know .NET core is cross-platform but it would be hard to publish a .NET core project on Linux OS. Do not worry, KLCWEB has a solution and guides to install .net core to Linux OS. Let’s install.net core in Linux OS.

1.) Install required component

sudo apt-get update
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-3.1
sudo apt-get install dotnet-runtime-3.1
sudo apt-get install aspnetcore-runtime-3.1

2.) Configure Apache server

Once You did install all the .NET core required components for Linux then, configure the Apache server to run the .NET core on Linux OS.

sudo apt-get install apache2
sudo a2enmod proxy proxy_http proxy_html proxy_wstunnel
sudo a2enmod rewrite

Now, you need to make configuration file for proxy on Apache

> sudo nano /etc/apache2/conf-enabled/netcore.conf

VirtualHost *:80>
ServerName www.DOMAIN.COM
ProxyPreserveHost On
ProxyPass / http://127.0.0.1:5000/
ProxyPassReverse / http://127.0.0.1:5000/
RewriteEngine on
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
RewriteRule /(.*) ws://127.0.0.1:5000/$1 [P]
ErrorLog /var/log/apache2/netcore-error.log
CustomLog /var/log/apache2/netcore-access.log common
</VirtualHost>

Paste this code to config file of Apache server, ensure that you will replace www.domain.com > your real domain name.

3.) Restart Apache server

sudo service apache2 restart
sudo apachectl configtest

4.) Start .NET service.

You need to move your all projects files to specific path using the below command.

sudo cp -a ~/release/ /var/netcore/

> Now, Create a service file for you .NET core project.

sudo nano /etc/systemd/system/ServiceFile.service

Now, restart your server using the below code.

sudo systemctl enable {Service Name}
sudo systemctl start {Service Name}
