First up, good work on working out how to install the LDAP module for PHP! You are on your path to becoming a Linux master! :)

As a bit of a (perhaps somewhat off topic) heads up, we're (still) in the process of our newer v15.0 release (see here and here). As you can see we haven't yet released a new Dokuwiki appliance, but it should be coming within the next few weeks.

The main reason why I mention that, is that the way we install Dokuwiki has completely changed. Dokuwiki was in the Debian repositories in Jessie (what v14.x was based on). But it's since been removed, so for v15.0 we've installed directly from upstream (i.e. direct from Dokuwiki devs). That has both upsides and downsides. The main downside is that you'll no longer get auto security updates for the Dokuwiki software itself. The other major downside is that migrating data from a v14.x appliance to the new v15.0 one will be a bit of a pain.

The upside is that it will be a significantly newer version of Dokuwiki. And the file locations should match what you'd be expecting (in context of your existing Windows install).

So unless you are in a rush, you may be better off waiting a couple of weeks until we have the v15.0 appliance ready?

Having said that, migration will be possible and will provide an opportunity to hone your Linux skills a bit! :)

But to get back to your current issue at hand. I'm not sure and no one has reported this before that I'm aware of. Although my first guess would be that it's to do with missing and/or incorrect permissions. Looking at the v14.2 build code I can see that the conf script was setting the permissions on a few locations to be owned by the webserver user account (www-data). My guess is that some more of those directories need to be owned by www-data to make it work as you'd expect.

The blunt instrument approach would be to give ownership to the whole directory tree to www-data. I.e. something like this: chown -R www-data:www-data /var/lib/dokuwiki/ (chown is "change owner", "-R" is recursive, so all files and directories, www-data:www-data is user:group and /var/lib/dokuwiki/ shoudl be where all/most of the user files for Dokuwiki are located). Whilst it's likely the easiest way to get it going, it's also not ideal. The reason why we generally keep everything other than what is required owned by root, is that even if your server gets hacked by a bad guy, then the amount of damage they can do is quite limited.

The more precise way to go would be to work out exactly what directories www-data needs access to and only grant those. Unless you are already familiar with Dokuwiki and it's ideal permissions, that may require a bit of trial and error.

One way you may be able to work out what the precise issue is, is by checking the Apache logs. I reckon the one you'll want to look at will be /var/log/apache2/error.log. If that makes no sense to you, please feel free to post it (or at least the last few lines of it) here. Here's some commands to assist with that. First is to display the whole log file, the second is to display the last 20 lines:

cat /var/log/apache2/error.log
tail -20 /var/log/apache2/error.log

Hope that gets you going. Please post back with further questions/info/etc and I'll respond ASAP.

I just took a look at Dokuwiki appliance with virtualbox.

Not much of a difference really - only that i have some additional addons (important for me is the upgrade plugin - as it makes life a lot easier. Also - as it is developed by the dokuwiki founder/main programmer (a. gohr) it is sure not to be left alone and stay maintained) - and i made the directories (extensions/templates etc) writeable to be able to add plugins or change template.

For the normal user it will be fine and easy to use.

Btw - as i am new i don't know if it is available somehow - but as i compared bitnami and turnkey a little bitnami has much more documentation. Maybe kind of a wiki where everyone could add the solutions to the problems they faced in a faq way or so would be an idea). For comparision: with bitnami one of the main general faqs was how to get files onto your vm (enabling ssh to use ftp and such) or how to access phpmyadmin (ssh tunnel), while in program specific general problems like "how to migrate" was included. I don't know if maybe this is overkill as you can find most of these answers in the forums etc. of the used programs themselves - but its just a thought.

Reason for the thought is that users new to linux may face the only thing i can think of when installing turnkey dokuwiki: writing rights.

So you have to "simply" enter chown -R www-data:www-data /var/www/html/ (or wherever your dokuwiki installation is).

But you can find the answer to that and a lot of howtos yourself. But guess i can't speak for everyone.

Mysql ? Adminer? Not really needed - aren't they?
