have changed a folder to www-data, but apache is still not able to create file on it
I have several folder that I use for uploading file from PHP. I have change the group permission of this folder to www-data ( a group that apache2 also shares ). but somehow I am still not able to upload a file to it. I think I miss some small thing, but I'm not really sure what it is. Any idea?
Below is my folder configuration :
ubuntu@myip:~/tweb/Server/myserver/assets$ ls -l
total 112
drwxrwsr-x 2 ubuntu www-data 4096 Aug 23 10:02 attachment
drwxrwxr-x 2 ubuntu www-data 4096 Aug 23 10:02 photo
drwxrwsr-x 2 ubuntu www-data 16384 Aug 23 10:02 logo
Below is the screenshot of the apache instance.
ubuntu@myip:~/tweb/Server/myserver/assets$ ps aux | grep apache

When I checked to which group www-data is belong to, it seems that the user is belong to www-data group.
groups www-data
www-data : www-data
Solution 1:
In order to write to a new file in a directory, the user needs write permission on the directory. It also needs scan ('x') permission on every one of that directory's parent directories.
