Question

我在TinyCore64机器上配置postgresql服务器，尽管我已经更改了权限，所有权和所有内容的组，但仍有一些文件和文件夹无法被用户postgres访问。以下是命令和文件夹结构：

sudo -u postgres ls /etc/ssl/
# success
# Permissions: drwxr-xr-x   6 root root

sudo -u postgres ls /etc/ssl/private
# ls: cannot open directory /etc/ssl/private/: Permission denied
# Permissions: drwxr-xr-x   2 postgres postgres

我很难过。我做错了什么？

检查＆＃34; / etc / ssl＆＃34;的权限目录 - 似乎＆＃39; postgres＆＃39;您系统上的用户没有＆＃39; rx＆＃39;权利在某个目标的完整路径上。

应该像：

kaa@aknb5:~$ ls -l /etc/ |grep ssl
drwxr-xr-x  4 root root     4096 Jun 13 11:00 ssl
kaa@aknb5:~$ uname -a
Linux aknb5 3.2.0-61-generic-pae #93-Ubuntu SMP Fri May 2 21:46:08 UTC 2014 i686 i686 i386 GNU/Linux
kaa@aknb5:~$

Linux权限问题：＆＃34;权限被拒绝＆＃34;
