logrotate 使用所有 CPU 功率

logrotate 使用所有 CPU 功率

我有默认的 Debian 8.5 Jessie/etc/logrotate.conf内容:

# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
#compress

# packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp, or btmp -- we'll rotate them here
/var/log/wtmp {
    missingok
    monthly
    create 0664 root utmp
    rotate 1
}

/var/log/btmp {
    missingok
    monthly
    create 0660 root utmp
    rotate 1
}

# system-specific logs may be configured here

通过此设置logrotate可以很好地完成其工作。但是,如果我改变:

rotate 4

到不同的东西,例如:

rotate 5

logrotate它永远不会完成它的工作,消耗所有的 CPU 能力,所以我最终不得不终止它的进程。

这是为什么?调整时我应该改变一些东西吗rotate

尝试寻找一些命令来解析/调试 logrotate 配置而不实际应用它。

man logrotate

     -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.

使用你会运行

logrotate -d /etc/logrotate.conf
