AWS Amazon Linux EC2实例:拒绝写到目录的apache用户权限

I am getting a permissions denied error when trying to write to the system/cache directory for the apache user and group (calling from HTTP :80 via web browser)

当尝试为apache用户和组写入系统/缓存目录时，我将获得一个被拒绝的权限错误(通过web浏览器从HTTP:80调用)

I have the folder permissions set like:

我将文件夹权限设置为:

[ec2-user@ip-172-31-45-8 system]$ ls -lah
total 48K
drwxrwsr-x 10 ec2-user www 4.0K Nov 24 05:05 .
drwxrwsr-x  7 ec2-user www 4.0K Nov 24 04:59 ..
drwxrwsr-x  2 ec2-user www 4.0K Nov 24 05:05 cache
drwxrwsr-x  2 ec2-user www 4.0K Nov 24 04:03 database
drwxrwsr-x  2 ec2-user www 4.0K Nov 24 04:03 engine
-rw-rw-r--  1 ec2-user www  924 Nov 24 04:03 file_merge.php
drwxrwsr-x  2 ec2-user www 4.0K Nov 24 04:03 helper
drwxrwsr-x  2 ec2-user www 4.0K Nov 24 05:02 library
drwxrwsr-x  3 ec2-user www 4.0K Nov 24 04:53 plugins
-rw-rw-r--  1 ec2-user www 3.3K Nov 24 04:03 startup.php

Apache Groups are set like this (I realize not a good idea to set apache to root group, but for testing purposes...):

Apache组的设置是这样的(我意识到将Apache设置为根组不是一个好主意，但是为了测试目的……)

[ec2-user@ip-172-31-45-8 system]$ groups apache
apache : www root wheel ec2-user apache

[ec2-user@ip-172-31-45-8 system]$ groups ec2-user
ec2-user : ec2-user wheel apache www

I have a script that tries to write to the system/cache/ directory which permissions are set to rwx for ec2-user and www. Apache is configured to use:

我有一个试图写入系统/缓存/目录的脚本，该脚本将ec2-user和www的权限设置为rwx。Apache被配置为使用:

User apache;
Group apache;

Chaning config to use www group fixes the problem, but I am confused why I cannot get it to work w/ group apache??

Chaning config使用www group修复了这个问题，但是我不明白为什么我不能让它在w/ group apache上工作?

User apache;
Group www;

Am I not understanding the way groups work on linux??

我不理解在linux上分组的工作方式吗?

1 个解决方案

#1

I'm not a proficient Linux or AWS user, but try adding the apache user to the www group:

我不是一个熟练的Linux或AWS用户，但是尝试将apache用户添加到www组:

sudo usermod -a -G www apache

sudo usermod - - - gwww apache。

Then restart apache:

然后重新启动apache:

sudo service httpd restart

或

sudo service apache2 restart

Then confirm apache is part of the www group

然后确认apache是www组的一部分。

grep 'www' /etc/group

That seemed to correct the problem for me. Just an FYI, I set up my EC2 server following these instructions.

这似乎可以纠正我的问题。仅供参考，我按照以下说明设置了我的EC2服务器。
