我试图配置 rsyslog 以将日志从特定文件转发到 syslogserver,但最终我清除了整个配置(rsyslog 服务卡住了 - 无法启动)..
所以我清除了所有内容,然后再次从头开始安装所有内容...现在当我尝试启动它时它失败了。
这是操作系统版本:
~# cat /etc/os-release

different pid files for them (-i option).

我在这里有点卡住了...我用谷歌搜索了“pid 已经存在”消息和许多其他消息,但毫无结果 :(
我将非常感激您的推动 :( 您知道我需要做什么吗?

两者都处于非活动状态。然后我检查是否有任何活动的 PID(全部良好)
~# ps axu | grep rsyslog
root 22747 0.0 0.0 6072 888 pts/0 S+ 14:59 0:00 grep rsyslog
验证是否存在 pid 文件ls /var/run/ | grep syslog
(无)
然后我启动了该服务,结果出现了超时消息
~# systemctl start rsyslog
Job for rsyslog.service failed because a timeout was exceeded.

我错过了什么?
答案1
rsyslog 的默认 PID 文件位置是/var/run/rsyslogd.pid
(如中所述man rsyslogd
)。cat
查看该文件以了解里面的内容。
检查该 PID 是否确实正在运行rsyslogd
(类似于ps axu | grep $(cat /var/run/rsyslogd.pid)
和ps axu | grep rsyslogd
)。如果它正在运行,请按照建议将其终止并删除 PID 文件。这是服务管理器认为服务未运行而实际上正在运行的问题(例如,无法停止)。
如果 PID 存在但不存在rsyslogd
,请不要终止它。它可能不相关,并且该操作可能会造成伤害而不是好处。只需删除 rsyslog PID 文件。发生这种情况可能是因为 rsyslog 创建了该文件,将其 PID 放在那里然后停止,系统后来将该 PID 重新用于其他用途。
现在,当服务显然没有运行和没有误导性的 PID 文件,尝试使用服务管理器重新启动它,观察/var/log/daemon.log
和其他日志文件(messages
、syslog
)中的启动情况并检查启动过程中是否有任何错误。
有趣的是,自 Debian 11 以来,它被配置为不是写入任意PID文件(启动类似/usr/sbin/rsyslogd -n -iNONE
)。
答案2
我认为这是通过以下链接报告的错误:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=815862
这看起来有悖常理...但实际要执行的步骤是您必须停止两个 systemd 单元,而不仅仅是停止rsyslog.service
或终止 rsyslog 的 PID:
systemctl stop syslog.socket rsyslog.service
