Change apache umask for modified files

Change umask (privileges) for files modified by Apache

Intro

By default, umask is set to 022, which means 755 for folders and 644 for non-executable files.
In this case, only owner can change the contents of the file.

So let's imagine, that You've uploaded some stuff. By default, only You will be able to change the content, and apache will be shooting error messages.

Solution

1. Create special user for web content management (for example admin)
2. Change his umask

echo "umask 002" >> /home/admin/.bashrc
echo "umask 002" >> /home/admin/.bash_profile

</pre>

Here comes systemd part :))

3. vim /usr/lib/systemd/system/httpd.service 

4. Paste

UMask=0002

in to [Service] section

5. <ESC>, : , write <ENTER> , quit <ENTER> 
 :))
5. systemctl daemon-reload
6. systemctl restart httpd.service
7. Test !

Test of solution

1. Create php file

<?php
  $file = fopen("testfile.text", "w") or die("ERROR !");
  $text = "Check privileges now !\n";
  fwrite($file, $text);
  fclose($file);
  sleep(1); // Simple DDoS protection
?><br>

2. Check if privileges of testfile.text are correct
