在Kylin3.2上安装dotnet SDK 2.1.300

1. 下载

• ICU libraries下载地址
• dotnet SDK 2.1.300 RHEL6专用版下载地址

2. 安装ICU libraries

用管理员权限，直接解压icu包到根目录，这包里嵌套了usr/local目录，所以解压只需指定根目录/就行

tar -xf icu4c-57_1-RHEL6-x64.tgz -C /

3. 安装dotnet SDK

解压至任意目录

tar -xf dotnet-sdk-2.1.300-rhel.6-x64.tar.gz -C /root/dotnet

4. 运行dotnet

在运行前需要指定一个环境变量，即ICU库所在的目录

export LD_LIBRARY_PATH=/usr/local/lib

这是临时有效，要想永久生效，要把此环境变量加到系统文件中。
然后，切换到dotnet所在目录运行dotnet --info，如果一切顺利会显示如下信息：
