어떤 아이디어가 있나요?
답변1
sshd여기에도 비슷한 오류가 있었습니다. 시작 시 디렉터리를 생성할 수 없는 것처럼 보였으 /run/sshd므로 여기서는 다음과 같은 스크립트를 통해 수행했습니다.
다음에서 sshddir스크립트를 작성하십시오 /etc/init.d/.
#!/bin/sh
### BEGIN INIT INFO
# Provides: sshddir
# Required-Start: $all
# Required-Stop: $network
# Should-Start: $network
# Default-Start: 3 4 5
# Default-Stop: 0 1 2 6
# Short-Description: Sshd /run/sshd Directory
# Description: Intended to create /run/sshd directory for Sshd.
### END INIT INFO
mkdir -p /run/sshd
chmod -R 755 /run/sshd
$ sudo chmod 755 /etc/init.d/sshddir
$ sudo update-rc.d sshddir defaults
이렇게 하면 재부팅하고 액세스할 수 있습니다.

다음 내용으로 sshddir.service파일을 생성하세요 /etc/system/systemd/.
[Unit]
Description=Run Sshd Directory Creator
After=network.target auditd.service
ConditionPathExists=!/etc/ssh/sshd_not_to_be_run
[Service]
ExecStart=/usr/bin/sshddir
ExecReload=/usr/bin/sshddir
Restart=always
RestartPreventExitStatus=255
Type=forking
[Install]
WantedBy=multi-user.target
Alias=sshddir.service
그 다음에:
2a-$ sudo systemctl daemon-reload
2b-$ sudo systemctl enable sshddir
하지만 호스팅된 파일을 먼저 삭제해야 합니다 SysVinit.
1a-$ update-rc.d sshddir disable
1b-$ update-rc.d sshddir remove
그런 다음 기기를 다시 시작하세요.
systemd시작 시 폴더가 삭제되어 오류가 발생한 것 같습니다 ./run/sshd
