logrotate 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create 0660 me www-data指定的权限目录中实际日志文件的文件权限有关？

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

我明白了

$ 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).

好吧，愚蠢的情况。 logrotate 命令必须在配置文件而不是日志文件上执行。

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

日志文件的父目录不可全局写入 (------rw-) 并且不可被任何非 root 组 (---rw----) 写入，这似乎很重要。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.
