서버를 다시 시작할 때 내 시스템 장치가 실행되지 않는 이유는 무엇입니까?

서버가 다시 시작될 때 시스템 서비스 단위 파일이 올바르게 실행되도록 할 수 없습니다. 서버는 CentOS 7.0.1406을 새로 설치한 것입니다. 여러 Apache httpd 인스턴스를 사용하여 이를 설정하려고 합니다. 이전 CentOS 설치에서는 httpd 인스턴스가 제대로 작동했으므로 이제 systemd를 사용하여 이러한 구성을 새 CentOS로 포팅하려고 합니다.

문제 없이 서비스를 활성화, 시작, 다시 시작 및 중지할 수 있습니다. 재부팅하면 "해당 파일이나 디렉터리가 없습니다"라고 뜹니다. 서비스를 다시 활성화하면 다음에 재부팅할 때까지 모든 것이 정상으로 돌아갑니다.

서비스 파일:

[Unit]
Description=Apache web server instance apache01
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/data/apacheinstances/apache01/logs/httpd.pid
ExecStart=/data/apacheinstances/apache01/bin/apachectl start
ExecStop=/data/apacheinstances/apache01/bin/apachectl stop
ExecReload=/data/apacheinstances/apache01/bin/apachectl reload
PrivateTmp=true
LimitNOFILE=infinity

[Install]
WantedBy=multi-user.target

어떻게 활성화하나요?

ln -s '/data/apacheinstances/apache01/bin/apache01.service' '/etc/systemd/system/multi-user.target.wants/apache01.service'

재부팅하기 전에는 제대로 작동했지만 재부팅 후에는 실패하는 이유를 잘 모르겠습니다. 다시 활성화하지 않으면 "해당 파일이나 디렉터리가 없습니다"라는 동일한 오류가 계속 발생합니다.

찾을 수 없는 파일이나 디렉터리를 확인하기 위해 systemd의 로깅 기능을 조사해 보았지만 아무 것도 발견되지 않았습니다.

이전에 이런 행동을 경험한 사람이 있나요?
