CentOS 7 上で ASP.NET Core アプリケーションを動かす

n 番煎じだとは思うが、 C# でコマンドラインツールとかウェブアプリケーション少し触るかなーと思いたったので、まずは動くところまでやってみた個人用メモ

環境

  • CentOS 7.5
$ cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)

環境構築

$ sudo rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm
$ sudo yum update -y
...
$ sudo yum install dotnet-sdk-2.1 -y
...
$ dotnet --version
2.1.301

コンソールアプリケーションで Hello, World!

$ dotnet new console -o myApp
$ cd myApp/
$ cat ./Program.cs
using System;

namespace myApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}
$ dotnet run
Hello World!
$ dotnet publish -c release -r linux-x64
