CentOS下 dotnet: command not found
CentOS 8,之前装的2.1是正常的，然后卸载了，再装了3.1的SDK就炸了,始终command not found
[root@iZwz9883ha8ul4wcjros0tZ /]# sudo dnf install dotnet-sdk-3.1
Last metadata expiration check: 2:55:32 ago on Sat 29 Aug 2020 06:44:23 PM CST. Package dotnet-sdk-3.1-3.1.401-1.x86_64 is already installed.
Dependencies resolved.
Nothing to do.
Complete!
[root@iZwz9883ha8ul4wcjros0tZ /]# dotnet --info
-bash: dotnet: command not found
[root@iZwz9883ha8ul4wcjros0tZ /]# whereis dotnet

待解决
你这个是忘记卸载host了 所以dotnet命令无效。
正确做法 卸载全部netcore包 命令：【sudo yum remove dotnet-host】，（https://docs.microsoft.com/zh-cn/dotnet/core/install/remove-runtime-sdk-versions?pivots=os-linux）里有写。
然后重新安装
1，sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm2，sudo yum install dotnet-sdk-5.0 （这步骤SDK包已经包含了运行时）
安装完毕后 执行 dotnet --info 就可以了，如果出现info信息 就ok了，不用再添加软连接啥的
