systemd-networkd와 NetworkManager는 모두 자체적으로 시작됩니다.

우분투 20.04 입니다.

systemd-networkd를 중지하고 비활성화했습니다. 그런 다음 NetworkManager를 활성화합니다. 그러나 다시 시작한 후에 두 서비스가 모두 나타납니다. 이것은 끊임없이 발생합니다. nmcli를 사용하여 서버를 관리하고 싶지만 작동 방법(및 네트워킹 중지)을 잘 모르겠습니다.

  349  systemctl stop systemd-networkd
  350  nmcli dev status
  351  systemctl restart network-manager
  352  systemctl status network-manager
  364  systemctl status systemd-networkd
  365  systemctl disable systemd-networkd
  366  systemctl status NetworkManager
  367  systemctl enable NetworkManager

---다시 시작한 후----

이제 DHCP를 사용하여 eno1의 네트워크에서 호스트로 SSH를 통해 연결할 수 있지만 나중에 이를 정적으로 만들고 싶습니다.

그 이후로 나는 이렇게 했습니다:

IP 주소는 이제 정적이지만 nmcli는 여전히 이를 관리할 수 없으며 라우팅 테이블이 변경된 것 같습니다.

systemd-networkd를 중지한 다음 netplan apply를 실행하면 오류가 발생합니다.

# systemctl stop systemd-networkd
# netplan apply
Failed to reload network settings: No such file or directory
Falling back to a hard restart of systemd-networkd.service

그런 다음 귀하의 제안을 시도했습니다.

# systemctl stop systemd-networkd
# systemctl disable systemd-networkd
# systemctl mask systemd-networkd
Created symlink /etc/systemd/system/systemd-networkd.service → /dev/null.
# systemctl restart NetworkManager

이제 완전히 미쳤습니다.

# netplan apply
Failed to reload network settings: No such file or directory
Falling back to a hard restart of systemd-networkd.service
Failed to restart systemd-networkd.service: Unit systemd-networkd.service is masked.

During handling of the above exception, another exception occurred:

nmcli/NetworkManager를 제외한 모든 것을 더 이상 사용하지 않으려고 했습니다. 이것은 너무 복잡해지고 있습니다.
