logrotate的权限问题

Question

我正在为一些web应用程序编写自己的logrotate配置：

/home/me/public_html/logs/*.log {
    daily
    missingok
    rotate 15
    compress
    delaycompress
    notifempty
    create 0660 me www-data
    nosharedscripts
}

但是对这些文件运行logrotate会导致：

$ sudo logrotate -d -v *.log
Ignoring logfile1.log because of bad file mode.
Ignoring logfile2.log because of bad file mode.
Ignoring otherlogfile.log because of bad file mode.

Handling 0 logs
$ ls -l
-rw-rw---- 1 me www-data  893584 Jan 27 16:01 logfile1.log
-rw-rw---- 1 me www-data  395011 Jan 27 16:01 logfile2.log
-rw-rw---- 1 me www-data 4949115 Jan 27 16:01 otherlogfile.log

这是否与目录中实际日志文件的文件权限与create 0660 me www-data指定的权限相关

如果我将文件权限更改为-rw-r-----，并将create行更改为

create 0640 me www-data

我得到了

$ sudo logrotate -d -v *.log
Ignoring logfile1.log because the file owner is wrong (should be root).
Ignoring logfile2.log because the file owner is wrong (should be root).
Ignoring otherlogfile.log because the file owner is wrong (should be root).

Handling 0 logs

好吧，愚蠢的情况。必须对配置文件而不是日志文件执行logrotate命令。

$ sudo logrotate -d -v /etc/logrotate.d/my-app

日志文件的父目录不是完全可写的(------rw-)，也不是任何非root组(---rw----)都能写的，这一点似乎很重要。否则，您将看到：

error: skipping "/home/me/public_html/logs/logfile1.log" because parent
directory has insecure permissions (It's world writable or writable by 
group which is not "root") Set "su" directive in config file to tell
logrotate which user/group should be used for rotation.
