logrotate:日志不需要轮换

Question

logrotate没有旋转我的日志

要验证日志文件是否为空，请执行以下操作：

# ls -laFh /var/log/cisco-meraki.log
-rw-r----- 1 root adm 2.8G Sep  5 13:23 /var/log/cisco-meraki.log

配置(/etc/logrotate.d/zzzzz_default)：

"/var/log/cisco-meraki.log" {
    daily
    rotate 10
    compress
    missingok
    notifempty
    create
}

全局配置(logrotate.conf)：

daily
rotate 10
create
include /etc/logrotate.d
/var/log/wtmp {
    missingok
    monthly
    create 0664 root utmp
    rotate 1
}
/var/log/btmp {
    missingok
    monthly
    create 0660 root utmp
    rotate 1
}

尝试手动运行：

# logrotate --verbose -d zzzzz_default
reading config file zzzzz_default

Handling 1 logs

rotating pattern: "/var/log/cisco-meraki.log"  after 1 days (10 rotations)
empty log files are not rotated, old logs are removed
considering log /var/log/cisco-meraki.log
  log does not need rotating

要验证问题不是“已完全旋转的”，我检查了：

# cat /var/lib/logrotate/status|grep cisco
"/var/log/cisco-ace.log" 2016-1-19-16:0:0
"/var/log/cisco-pix.log" 2016-1-19-16:0:0
"/var/log/cisco-acs.log" 2016-1-19-16:0:0
"/var/log/cisco-asa.log" 2016-1-19-16:0:0
"/var/log/cisco-router.log" 2016-9-6-0:1:1
"/var/log/cisco-ips.log" 2016-1-19-16:0:0

..but no cisco-meraki.log

Answer 1

来自logrotate手册页：

      -d, --debug
           Turns on debug mode and implies -v.  In debug mode, no
           changes will be made to the logs or to the logrotate
           state file.

我也遇到了完全相同的问题！

请参阅https://unix.stackexchange.com/a/96947

假设您今天创建了zzzzz_default文件。logrotate将在/var/lib/logrotate/中创建一个条目，状态就像它今天轮换日志一样。

当您现在运行logrotate --verbose -d zzzzz_default 时， logrotate会检查它上次轮换日志时读取的/var/lib/logrotate/status。它将找到之前创建条目，因此它将显示为log does not need rotating

如果您明天运行logrotate --verbose -d zzzzz_default ， logrotate会检查上次轮换日志的/var/lib/logrotate/status。它将不会找到该条目，因此它将轮换日志文件。
