I am having a really tough time understand user/group permissions. I have spent hours reading and trying things. Here is what I have:
Directories Permissions
Input 1: ls -lhd
Output 1:
/var/log: drwxrwxr-x 11 root syslog 4.0K May 10 01:59 .
/var/log/mongosqld: drw-rw-r-- 2 mongosqld logstash 4.0K May 10 03:37 .
Note: I set this up using chown
and chgrp
.
File Permissions
Input 2: ls -lh
Output 2:
/var/log/mongosqld:
total 12K
-rw-rw-r-- 1 mongosqld logstash 1.4K May 10 03:43 mongosqld.log
Groups:
Input: groups logstash mongosqld
Output:
logstash : logstash
mongosqld : users logstash
My Question
When I try to open a file as the mongosqld
user, it tells me open /var/log/mongosqld/mongosqld.log: permission denied
. Where I am going wrong.
sudo chmod +x /var/log/mongosqld/
, and the case is closed! I am wondering, do you know why open requires execute? In my mind, that is a write permissions kind of thing. – Intrastellar Explorer May 10 '19 at 15:38
