我编写了以下 systemd 单元,如下所示/etc/systemd/system/regen-ssh-keys.service
:
[Unit]
Description=OpenSSH Server Key Generation
# Do not run if keys already exist
ConditionPathExistsGlob=!/etc/ssh/ssh_host_*_key
# This service requires rng-tools to feed the random number generator,
# otherwise we may generate predictable keys without noticing it.
Requires=rng-tools.service
After=rng-tools.service
# sshd needs this service to be run and finished before starting
PartOf=sshd.service sshd.socket
Before=sshd.service sshd.socket
[Install]
# sshd needs this service to be run and finished before starting
WantedBy=sshd.service sshd.socket
[Service]
EnvironmentFile=-/etc/sysconfig/sshd
ExecStart=/usr/bin/ssh-keygen -A
Type=oneshot
RemainAfterExit=yes
并且我用 启用了它systemctl enable regen-ssh-keys
。
它不会在启动时或 ssh 启动时启动,尽管service regen-ssh-keys status
它显示已加载并启用,但处于“非活动状态(已死)”。此外,它也没有被列出systemctl -a
。
但是,当我用 手动启动它时service regen-ssh-keys start
,它会按预期启动。
我在编写单元时是否做错了什么?
答案1
这个错误只是我没有使用正确的 SSH 服务名称。用 替换 即可sshd.service sshd.socket
解决ssh.service ssh.socket
问题。
