.NET Core 1.0 CentOS7 尝试(一、安装)

  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/bin

We 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

官网提供的HelloWorld实例，执行如下：

[sonny@bogon hwapp]$ dotnet run

Compiling hwapp for .NETCoreApp,Version=v1.0

Compilation succeeded.
    0 Warning(s)
    0 Error(s)

Time elapsed 00:00:05.8154656
 

Hello World!

瞅瞅这个实例的目录结构：

[sonny@bogon dotnet]$ cd hwapp
[sonny@bogon hwapp]$ ls
bin  obj  Program.cs  project.json  project.lock.json
[sonny@bogon hwapp]$ cd bin
[sonny@bogon bin]$ ls
Debug
[sonny@bogon bin]$ cd Debug
[sonny@bogon Debug]$ ls
netcoreapp1.0
[sonny@bogon Debug]$ cd netcoreapp1.0/
[sonny@bogon netcoreapp1.0]$ ls
hwapp.deps.json  hwapp.pdb                     hwapp.runtimeconfig.json
hwapp.dll        hwapp.runtimeconfig.dev.json
[sonny@bogon netcoreapp1.0]$ 

根目录跟平常开发没啥区别，多了 project.json project.lock.json 这两个文件。

三、project.json 与 project.lock.json

project.json很好理解，就是之前一堆配置的合并。

project.lock.json,参考:http://blog.falafel.com/what-is-project-lock-json/
