我刚刚意识到,自从升级到 22.04.1 后,logrotate 无法正常工作。Syslog 已经很多天没有轮换过了。它应该由 systemd 计时器运行,并激活相关计时器:
# systemctl list-timers

16 timers listed.
根据系统日志,logrotate 也在运行:
Sep 14 00:00:08 server1 systemd[1]: logrotate.service: Deactivated successfully.
Sep 14 02:30:41 server1 systemd[1]: logrotate.timer: Deactivated successfully.
Sep 15 00:00:01 server1 systemd[1]: logrotate.service: Deactivated successfully.
Sep 15 02:30:42 server1 systemd[1]: logrotate.timer: Deactivated successfully.
systemd 也确认了:
# systemctl status logrotate.timer
● logrotate.timer - Daily rotation of log files
Loaded: loaded (/lib/systemd/system/logrotate.timer; enabled; vendor prese>
Active: active (waiting) since Thu 2022-09-15 02:30:57 CEST; 20h ago
Trigger: Fri 2022-09-16 00:00:00 CEST; 1h 8min left
Triggers: ● logrotate.service
Docs: man:logrotate(8)
man:logrotate.conf(5)
Sep 15 02:30:57 server1 systemd[1]: Started Daily rotation of log fil
但是没有轮换日志。当我按照 logrotate.service 中的指定手动启动 logrotate 时,没有任何反应(没有输出,没有旋转日志):
root@server1:/usr/lib/systemd/system# /usr/sbin/logrotate /etc/logrotate.conf
root@server1:/usr/lib/systemd/system#
然后,当我使用 -vf 启动 logrotate 以查看问题所在时,日志确实已旋转:
root@server1:/usr/lib/systemd/system# /usr/sbin/logrotate -vf /etc/logrotate.conf
reading config file /etc/logrotate.conf
including /etc/logrotate.d
请问我应该如何调试它并让 logrotate 定期运行?
