Hy,

the most minimal solution is to give www-data write permissions (recursive) to the var directory of eZPublish. In there are stored the cache files, uploaded media-ressources (pdfs, images) and other stuff i cant remember right now.

A plus would be to give www-data writeaccess to settings/siteaccess/* and settings/override directorys when users would like to edit eZPublish ini-configurations via the admin-interface. I've never enabled/done that, so cannot totally ensure if above directorys are sufficient.

Another thing you might consider is give www-data permissions to design/* and/or extension/XXXX/design/xxxx/override/... folders if your developers tend using the ezpublish frontend-functionality to create template-overrides. I've never done this so I cannot ensure if those folders are the corresponding ones.

I've setup the files to be group writeable for www-data
chmod g+w xxx and chgrp www-data xxx so your developers are still the owners and www-data is able to write too - mostyl ;-)

cheers,
chris

Thanks Chris for the answer.

The problem is that there are more than one developer on each installation, and I don't want them to share the same account, so they normally own a file/dir, and give full permission to the 'users' group so others can work on it, too.

Then, as you said, you are not sure about your advice but I cannot make any mistakes (since all installation are in production already)...

So, does anybody have an answer?

(to be honest it seems a bit weird, to me, it's just us facing this issue: sure there should be some documentation already published, isn't it?)

ciao,

Francesco

I can't think of any major lack in Christian's list. The first one (var) is mandatory. Settings and design depend if you use the extensions & design features from the GUI.

@francesco "more than one developer on each installation" - I think you'd be better off using an scm tool where you can control complete change history on every file, rather than try to segregate developers using file permissions - at least as far as the dev and integration servers are concerned.

If you are talking about a prod server, giving each dev/admin an account, and making them all members of the same group is ok.

I confirm the list that Christian gave:

- by default only var/ needs to be writable

- var/autoload needs to be writable by apache if you want to be able to activate/deactivatate extensions via the admin gui

- settings/override, settings/siteaccess and extension/xxx/settings needs to be writable by apache if you want to be able to edit settings via the admin gui

- design/ and extension/xxx/design needs to be writable by apache if you want to be able to edit templates via gui

some more advice:

- you do not need to have stuff in var world-readable, if www-data is the group to which belong both the devs and apache. You can look for file permissions uses by ezp when creating things in config.php (EZP_INI_FILE_PERMISSION) , file;ini and image.ini

- if you run your cronjobs by processes other than apache, take care that if they crash they might leave lock files in the var/siteaccess/cache/ezmutex that later cannot be removed by apache. You can set up a cronjob to fix this

- setting up a cronjob that periodically checks for file perms is also a good idea if you fear your devs will create problems when uploading stuff with the bad provileges
