This problem happened in a recent apache release before version 2.4.55. I encountered this after a system upgrade a month ago.
Apache is unable to access /tmp in any way. We may let apache host some external websites by:
Alias "/ext" "/path/to/external" <Directory "/path/to/external"> Options Indexes Require all granted </Directory>
You can access that through http://yourwebsite/extThis works most of the time. Changing "/path/to/external" to any path works fine including /bin, /srv, /etc ...
Except for anything under /tmp. I always get 403 Forbidden for that.For other directories, as long as apache has access permission on them, I could always get their content listed.
Only for /tmp I get 403 Forbidden.Indexing (/ext) and actual file accessing (/ext/index.html) are both forbidden.
Why is /tmp different from others? Changing permission of /tmp to 755 does not work, either. Debug log here:
