CENTOS7 build. Netcore Operating Environment

Introduction to the development environment

1. Operating system: Windows Server R2 Enterprise

2.ide:visualstudio2017

3..Net Core 2.0 SDK

This article assumes that you have met the above criteria. The. NET core2.0 project is created and published successfully.

Download the. Net Core 2.0 SDK

1. Prepare a machine equipped with CENTOS7, IP set to: 192.168.1.10

2. Download the. Net Core 2.0 SDK for CENTOS7

: Https://www.microsoft.com/net/download/linux

3. Copy to Centos7

Enter CENTOS7 to create the/soft directory:

[Email protected] soft]# Mkdir/soft

Copy the downloaded dotnet-sdk-2.0.0-linux-x64.tar.gz to the/soft directory via the WINSCP tool

Installing the. Net Core 2.0 SDK

1. Unzip:

[Email protected] ~]# Cd/soft

[Email protected] soft]# mkdir-p $HOME/dotnet && tar zxf dotnet-sdk-2.0.0-linux-x64.tar.gz-c $HOME/dotnet

This order is officially provided by Microsoft, extracted to:/root/dotnet.

2. Edit the profile:

[Email protected] soft]# Vi/etc/profile

Copy "Export path= $PATH: $HOME/dotnet" to the bottom of the file, save and exit.

Refresh Profile

[Email protected] soft]# Source/etc/profile

3. View Dotnet Version:

[Email protected] soft]# dotnet–version

4. The finished thing, reported abnormal:

Failed to load, Error:libunwind.so.8:cannot open shared object file:no such file or directory

Failed to bind-CoreCLR at '/root/dotnet/shared/microsoft.netcore.app/2.0.0/libcoreclr.so '

Not afraid, because we did not install Libunwind, as long as the installation can be, execute the following command:

[email protected] soft]# Yum install Libunwind

5. Execute the above command again:

[Email protected] soft]# dotnet–version

6. Also reported exception:

Failfast:couldn ' t find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to True if you want to run with no globalization support.

Can we have a good play? This prompt tells us that the ICU is not installed and executes the following command:

[[email protected] soft]# Yum install ICU

7. Execute the above command again:

[Email protected] soft]# dotnet--version

This indicates that the installation was successful.

Running the ASP. NET Core Program

1. Modifying the Buildwebhost method of Program.cs

Obviously, add this line of code, we can not only use 80 port access, 5000 port can also.

2. Open port

You also need to turn on 80 ports and 5000 ports for external machines to be accessible.

[Email protected] coredemo]# firewall-cmd--zone=public--add-port=80/tcp--permanent

[Email protected] coredemo]# firewall-cmd--zone=public--add-port=5000/tcp--permanent

Restarting the firewall

[Email protected] coredemo]# Firewall-cmd–reload

3. Publish the ASP. NET core program and copy it to the Centos7/soft directory using the WinSCP tool

The project name I built is called: Coredemo, so what you see here is: Coredemo.

[Email protected] soft]# cd/soft/coredemo/

[Email protected] coredemo]# dotnet Coredemo.dll

warn:microsoft.aspnetcore.dataprotection.keymanagement.xmlkeymanager[]      No XML encryptor Configured. Key {6dfc9509-6201in/soft/coredemonow listening on:http://  192.168.1.10:5000nowlistening on:http://192.168.1.10:80Application Started. Press Ctrl+c to shut down.

This prompt indicates that our ASP. NET Core program is working properly.

4. Access

Enter the address on the browser of another machine: both http://192.168.1.10 and http://192.168.1.10:5000/can access

All right, it's done.
