A general linux file permissions question: Apache and WordPress
apache, linux, permissions, wordpress
Solution
What should I do to make them readable and writable by both kovshenin and apache?
- Create a new group, say "wordpress".
- Add both koveshenin and www-data users to the wordpress group.
- Change the group owner of all the files to wordpress (using chgrp).
- Make sure all the files are group writeable.
- Set the g+s (setgid) permission bit on all the directories of interest.
- Make sure kovshenin and apache's default umask includes group read & write permission.
The second last step is the trick. It means that whenever kovshenin or apache creates a file in those directories, the group owner will be set to wordpress (instead of kovshenin or apache).
Problem
I moved from a shared hosting to a VPS a few weeks ago and I'm having these annoying permission issues with WordPress. You know you can download and upgrade plugins (and wordpress itself) from the admin panel, but since I moved it started asking me my FTP credentials, which is kinda slow when I have to update ~20 plugins. I think this should be some kind of rights issue. I looked that the shared hosting wordpress files, they all belong to the username and group kovshenin (kovshenin:kovshenin) and the files are -rw-r--r-- and the directories are drwx-r-xr-x. On my VPS apache runs under apache:apache and my files are kovshenin:kovshenin. What should I do to make them readable and writable by both kovshenin and apache? Also, I changed the permissions to 0777 for all files and folders of my wordpress installation, that allowed me to install and delete plugins without FTP, but when I pushed to automatic upgrade to WordPress 2.8.1 it still asked me for my FTP account. Is that a wp issue or did I miss something? Thanks. Update: I managed to run `id` and `id www-data` on the MediaTemple shared hosting. User kovshenin is in group kovshenin, and www-data is in group www-data. No more groups. What's the trick? Another update Okay, I added the `apache` user to the `kovshenin` group, my wordpress files are `kovshenin:kovshenin` with `rw-rw-r--` permissions and `drwxrwxr-x` permissions on directories, but something is still wrong. The user `apache` can access the files and folders, I can use the online Themes and Plugins editor in the wordpress admin panel, I'm able to make changes to the .htaccess file from within wordpress, but plugin/theme installation still asks me for FTP credentials! Any ideas? Thanks.
