NET Core R2 Run Hello World

Install. NET Core R2 on CentOS 7 run Hello World

Objective

Last month, the latest version of the. NET Core was previewed, just experimenting on the window system. Originally wanted to release the official version of the time on the Linux system to try, it may take some time, just have a moment to toss.

Since the previously installed Ubuntu system is 16 and is not currently supported, it has not been tested on Ubuntu.

System Environment: CentOS 7 (1511) Minimal core version.

Installation

Tips:
Nodejs and Yeoman are used to automate the creation of ASP. NET projects, not mandatory items.
This article is an ASP. NET project created with Yeoman, so the installation of Nodejs and Yeoman is added.
Do not install if you feel you do not need it.

. NET core[must be]

1. Go to the official website to download. NET core:dotnet-dev-centos-x64.1.0.0-preview1-002702.tar.gz.

2. Move and unzip the downloaded installation file.

$ # CreateDotnet Folder $ mkdir ~/dotnet$ # copy dotnet install file to  Dotnet folder under $ cp dotnet-dev-centos-x64.1 .0.0-preview1-002702.tar.gz ~/< Span class= "Hljs-keyword" >dotnet$ # Unzip the installation file $ tar-xzf ~/dotnet/ Dotnet-dev-centos-x64.1.0.0- Preview1-002702.tar.gz$ # delete dotnet folder under the original file $ rm ~/dotnet/dotnet-dev-centos-x64.1.0.0-preview1-002702.tar.gz    

3. Add a soft connection that can be used globally.

-s ~/dotnet/dotnet /usr/local/bin

4. Test whether the installation was successful.

$ dotnet --version1.0.0-preview1-002702 #输出版本号

nodejs[Optional]

Do not use the system's own installation, the version is too low.

1. Go to the official website to download Nodejs installation files: Node-v4.4.5-linux-x64.tar.xz.

2. Copy and unzip.

# 创建nodejs文件夹$ mkdir /usr/local/nodejs$ # 复制node安装文件到nodejs文件夹下$ cp node-v4.4.5-linux-x64.tar.xz /usr/local/nodejs$ # 解压安装文件$ tar -zvxf /usr/local/nodejs/node-v4.4.5-linux-x64.tar.xz$ # 删除nodejs文件夹下的原文件$ rm /usr/local/nodejs/node-v4.4.5-linux-x64.tar.xz

3. Add a soft connection that can be used globally.

/usr/local/nodejs/node /usr/local/bin/node$ sudo ln -s /usr/local/nodejs/npm /usr/local/bin/npm$ sudo ln -s /usr/local/nodejs/node /usr/bin/node$ sudo ln -s /usr/local/nodejs/node /usr/lib/node$ sudo ln -s /usr/local/nodejs/npm /usr/bin/npm

4. Test whether the installation was successful.

$ node -vv4.4.5 #输出版本号$ npm -v3.9.5 #输出版本号

yeoman[Optional]

Yeoman is used to create an ASP, and requires the installation of the associated node plugin: Bower, Grunt, gulp.

1. Use NPM to perform installation commands

install -g yo bower grunt-cli gulp

Wait for the installation to complete.

2. Install the ASP.

install -g generator-aspnet

3. Adding system Variables

Add the Bin folder of node to the system variable, or you will be prompted that the plugin command installed by NPM does not exist.

Open the . BASHRC file in the user directory:

$ vi ~/.bashrc

Add the following at the tail:

export PATH="/usr/local/nodejs/bin":$PATH

Take effect with the source command:

source ~/.bashrc

vscode[Optional]

This can not be installed if you do not need to modify the code.

1. Go to the official website to download the installation package: vscode-x86_64.rpm

2. Perform the installation operation

$ rpm -ivh vscode-x86_64.rpm

3. Test whether the installation was successful.

If you can start vscode the installation is correct.
