.NET Core 1.0 CentOS7 尝试

昨天宣布 ASP.NET Core RC2，据说差不多稳定了，以后不会有大改了。

参考:https://blogs.msdn.microsoft.com/webdev/2016/05/16/announcing-asp-net-core-rc2/

一、环境装备

等待很久了，高兴之余昨晚安装一个CentOS系统，版本如下：

[root@bogon etc]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

二、安装并执行hwapp

参考官网的Install for CentOS 7.1介绍，参考地址:https://www.microsoft.com/net/core#centos

安装官网的步骤一步一步的来~~下载可能很慢，直接从官网下载比较快~~

如果在执行 sudo ln -s ~/dotnet/dotnet /usr/local/bin 这个命令错误，错误如下：

[sonny@bogon dotnet]$ sudo ln -s ~/dotnet/dotnet /usr/local/binWe trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:#1) Respect the privacy of others.#2) Think before you type.#3) With great power comes great responsibility.[sudo] password for sonny: 
sonny is not in the sudoers file.  This incident will be reported.

原因：CentOS禁用的root用户，而你新建的用户并没有添加到suduers中，所以需要手动添加。

解决方法，参考园有博客：http://www.cnblogs.com/evasnowind/archive/2011/02/04/1949113.html

安装完成之后，试一下：

[sonny@bogon ~]$ dotnet --info.NET Command Line Tools (1.0.0-preview1-002702)Product Information:Version:     1.0.0-preview1-002702Commit Sha:  6cde21225eRuntime Environment:OS Name:     centosOS Version:  7OS Platform: LinuxRID:         centos.7-x64

官网提供的HelloWorld实例，执行如下：

[sonny@bogon hwapp]$ dotnet run
Project hwapp (.NETCoreApp,Version=v1.0) will be compiled because expected outputs are missing
Compiling hwapp for .NETCoreApp,Version=v1.0Compilation succeeded.    0 Warning(s)    0 Error(s)Time elapsed 00:00:05.8154656Hello World!

瞅瞅这个实例的目录结构：

[sonny@bogon dotnet]$ cd hwapp
[sonny@bogon hwapp]$ lsbin  obj  Program.cs  project.json  project.lock.json
[sonny@bogon hwapp]$ cd bin
[sonny@bogon bin]$ lsDebug[sonny@bogon bin]$ cd Debug
