systemd의 파일에서 환경 변수를 사용하는 방법

다음과 같이 일부 파일에 환경 변수를 설정했습니다 /etc/profile.d/mercure.sh.

export MERCURE_PUBLISHER_JWT_KEY=$(cat /home/stephane/mercure/publisher.key.pub)
export MERCURE_PUBLISHER_JWT_ALG=RS256
export MERCURE_SUBSCRIBER_JWT_KEY=$(cat /home/stephane/mercure/subscriber.key.pub)
export MERCURE_PUBLISHER_JWT_ALG=RS256
export SERVER_NAME=localhost:3000

다음 명령을 실행하려면 이 정보가 필요합니다.머큐어 센터):

MERCURE_PUBLISHER_JWT_KEY=$MERCURE_PUBLISHER_JWT_KEY MERCURE_SUBSCRIBER_JWT_KEY=$MERCURE_SUBSCRIBER_JWT_KEY SERVER_NAME=$SERVER_NAME /usr/bin/mercure run

아래 설명과 같이 서비스로 실행할 mercure.service파일을 생성하고 싶습니다.mercure여기

처음에는 다음과 같은 오류가 발생했습니다.

$ sudo systemctl status mercure

내 라인에서 환경 변수를 사용하는 방법을 정말로 이해하지 못합니다 ExecStart. 누군가 설명하거나 예를 보여줄 수 있습니까?

답변1

.NET 파일 없이 더 간단한 환경 파일을 사용해 보세요 export.

ExecStart /bin/bash -c "...."다음과 같은 변수를 사용하고 싶다면$MERCURE_PUBLISHER_JWT_KEY

답변2

@frédéric-loyer 및 @AlexP의 답변의 도움으로 환경 변수를 설정 /etc/environment하고 mercure.service파일을 편집했습니다.

괜찮은 것 같습니다:

$ sudo systemctl status mercure

감사해요.
