systemd[1]: realmd.service 시작 작업 시간이 초과되었습니다. 종료

내 CentOS 7을 도메인에 넣으려고 하고 다른 것도 넣었는데 모든 것이 잘 작동하지만 이 컴퓨터는 작동하지 않습니다.

기계 구성은 다음과 같습니다.

Icon name: computer-vm
Chassis: vm
Virtualization: microsoft
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe: / o: centos: centos: 7
Kernel: Linux 3.10.0-514.26.2.el7.x86_64
Architecture: x86-64 

realmd 서비스 자체가 작동하지 않는다는 것을 알았을 때 CentO를 도메인에 넣는 방법을 따랐습니다.

"journalctl -xe" 로그를 따르십시오.
