Linux에서 .NET Core의 필수 구성 요소 설치 - .Net Core SDK 설치

CentOS 설치 내용 요약

1. 시스템에서 .NET Core의 이전 미리 보기 버전을 제거하세요.

2. Microsoft 서명 키를 등록합니다.

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc

3. Microsoft 제품 피드를 추가합니다.

sudo sh -c 'echo -e "[packages-microsoft-com-p rod]\nname=packages-microsoft-com-prod \nbaseurl=https://packages.microsoft.com/yumrepos/microsoft-rhel7.3-prod\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc"; > /etc/yum.repos.d/dotnetdev.repo'

4. .NET Core SDK를 설치합니다.

sudo yum update 
sudo yum install libunwind libicu 
sudo yum install dotnet-sdk-2.0.0

5. PATH에 dotnet 추가

export PATH=$PATH:$HOME/dotnet

6. dotnet --version 명령을 실행하여 설치 성공을 증명합니다.

dotnet --version

오류가 나는 경우 점검사항

1. 아래 주석 해제 처리

[root@api-test home]# vi /usr/local/apache/conf/httpd.conf
...
LoadModule proxy_http_module modules/mod_proxy_http.so
...

2. ExecStart=/usr/bin/dotnet /home/websvc/netcore.test.com/dotnetCoreSample.dll 에 있는 내용 실제 실행해본다.

[root@api-test home]# /usr/bin/dotnet /home/websvc/netcore.test.com/dotnetCoreSample.dll
info: Microsoft.AspNetCore.DataProtection.KeyManagement.XmlKeyManager[0]
User profile is available. Using '/root/.aspnet/DataProtection-Keys' as key repository; keys will not be encrypted at rest.

Hosting environment: Production
Content root path: /usr/local/apache/conf
Now listening on: http://localhost:5000
Application started. Press Ctrl+C to shut down.

3. 아파치 로그 확인으로 오류 원인 확인

[root@api-test logs]# tail -5000f /usr/local/apache/logs/netcore.test.com-error_log

==> 오류 원인 확인

첫번째 오류 -> LoadModule proxy_http_module modules/mod_proxy_http.so 주석 제거후 해결

[Fri Nov 03 13:41:17.536279 2017] [proxy:warn] [pid 17437:tid 140528444241664] [client 118.128.33.118:50659] AH01144:
No protocol handler was valid for the URL /favicon.ico (scheme 'http').
If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.

두번째 오류 ->

[root@api-test home]# /usr/share/dotnet /home/websvc/netcore.test.com/dotnetCoreSample.dll
-bash: /usr/share/dotnet: 디렉터리입니다

[root@api-test conf]# /usr/bin/dotnet /home/websvc/netcore.test.com/dotnetCoreSample.dll
