centos 编译.net core程序

总结如下：

sudo yum install libunwind libicu   #安装libunwind，libicu包

curl -sSL -o dotnet.tar.gz https://go.microsoft.com/fwlink/?LinkID=809131 #下载dotnet-dev-centos-x64.1.0.0-preview2-003121.tar文件，有时会因为网络问题下载较慢，耐心等待即可，当然也可以手动下载后放到目录下。

sudo mkdir -p /opt/dotnet && sudo tar zxf dotnet.tar.gz -C /opt/dotnet #创建目录并解压已下载文件
sudo ln -s /opt/dotnet/dotnet /usr/local/bin #将目录链接到$PATH下，否则dotnet命令无法识别

mkdir hwapp
cd hwapp

dotnet new #创建默认.NET Core应用
dotnet restore #还原依赖包
dotnet run #运行，结果将显示Hello World!
dotnet --info 可使用dotnet --info查看是否链接成功

运行命令教程： https://www.microsoft.com/net/core#windowscmd
.net 文档：https://docs.microsoft.com/zh-cn/dotnet/

具体流程如下：

[root@vm ~]# sudo yum install libunwind libicu
[root@vm ~]# curl -sSL -o dotnet.tar.gz https://go.microsoft.com/fwlink/?LinkID=809131
[root@vm ~]# mv dotnet-dev-centos-x64.1.0.0-preview2-003121.tar.gz dotnet.tar.gz   
mv：是否覆盖"dotnet.tar.gz"？ y
[root@vm ~]# ls
1.c  2.c  3.c  anaconda-ks.cfg  a.out  dotnet.tar.gz  initial-setup-ks.cfg  mysql-community-release-el7-5.noarch.rpm
[root@vm ~]# sudo mkdir -p /opt/dotnet && sudo tar zxf dotnet.tar.gz -C /opt/dotnet
[root@vm ~]# sudo ln -s /opt/dotnet/dotnet /usr/local/bin
[root@vm ~]# mkdir hwapp
[root@vm ~]# cd hwapp
[root@vm hwapp]# dotnet new

Telemetry
--------------
The .NET Core tools collect usage data in order to improve your experience. The data is anonymous and does not include commandline arguments. The data is collected by Microsoft and shared with the community.
You can opt out of telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1 using your favorite shell.
