更新yum

yum update -y
yum install unzip curl sudo libunwind8 gettext apt-transport-https -y

安装.NET Core Runtime

教程来自：Microsoft官网，不懂的话，直接运行下面的命令行即可

Add the dotnet product feed

sudo rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm

Install the .NET Runtime

sudo yum update
sudo yum install aspnetcore-runtime-2.2

剩下的运行不多写了，看之前写的Debian 9 的教程吧
