问题描述

我使用软件包管理器 apt-get 安装了 postgresql-common postgresql-9.4
我将数据库系统从OSX更改为Debian 8.1,此后遇到权限拒绝错误。
用户 postgres 存在( CREATE USER postgres; ),数据库 detector 存在使用OWNER = postgres创建数据库检测器; )。

I installed postgresql-common and postgresql-9.4 with the package manager apt-get. I changed my database system from OSX to Debian 8.1 after which I have had difficulties with Permission denied errors. The user postgres exists (CREATE USER postgres;) and database detector exists CREATE DATABASE detector WITH OWNER=postgres;).

我运行成功

masi@pc212:~$ sudo -u postgres psql detector -c "DROP TABLE measurements;"DROP TABLE
masi@pc212:~$ sudo -u postgres psql detector -c "CREATE TABLE measurements ( m_id SERIAL PRIMARY KEY NOT NULL, m_size INTEGER NOT NULL );"
CREATE TABLE

,但在Dropbox -directory中失败相同

but the same unsuccessfully in Dropbox -directory

masi@pc212:~$ cd Dropbox/
masi@pc212:~/Dropbox$ sudo -u postgres psql detector -c "DROP TABLE measurements;"
could not change directory to "/home/masi/Dropbox": Permission denied
DROP TABLE
masi@pc212:~/Dropbox$ sudo -u postgres psql detector -c "CREATE TABLE measurements ( m_id SERIAL PRIMARY KEY NOT NULL, m_size INTEGER NOT NULL );"
could not change directory to "/home/masi/Dropbox": Permission denied
CREATE TABLE



设置



命令 psql / etc / sudoers

Defaults        secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

命令 psql 给出 / usr / bin / psql

我保存的真实目录代码为 / home / masi / Dropbox / det / ,其中Dropbox的安装可能会影响到事情:

The real directory where I keep the code is /home/masi/Dropbox/det/ where possibly the Dropbox installation is affecting thing:


  • drwxr-xr-x 32 masi masi 4096 Jul 14 10:27 masi /

  • drwx ------ 26 masi masi 4096 Jul 13 16:05 Dropbox /

  • drwxr-xr-x 8个masi开发人员4096 Jul 14 09:22 det /

在这里我可以更改Dropbox到

where I can change the Dropbox to


  • drwx ------ 26位masi开发人员4096 Jul 13 16:05 Dropbox /

但无法增加权限,因为我开始获得 ls:尽管具有完全打开的权限,但无法访问../../Dropbox/:权限被拒绝
这是一个非常奇怪的行为,在这里完全开放的权限会导致这种行为。

but not able to increase permissions because I start to get ls: cannot access ../../Dropbox/: Permission denied although having fully open permissions. This is a very strange behaviour that here fully open permissions lead to such a behaviour.

类似错误

推荐答案

Petesh的评论中有一些答案,但还需要读取-flag。
运行

Some piece of answer in Petesh's comment but also read -flag is required. Run

sudo chmod -R go=rx /home/masi/Dropbox

,但请尽量避免递归。
该命令允许随后的 sudo -u postgres 命令。 通常,您必须打开对目录和所有父目录的访问权限,以允许命令使用目录中的文件。在所有情况下执行s的权限还不够。还需要read -flag。

but avoid recursive if you can. The command allows the subsequent sudo -u postgres commands. You generally have to open up access to the directory and all parent directories enough to allow commands to work with files in the directory. Execute s not enough in all cases; read -flag is also required.
