A wiki is a repository of dynamically created and managed content, or content created or edited by multiple users collaboratively. This article is about using the wiki service in macOS Server 5.4 (the Apple Server app running on 10.13/High Sierra). I reference file services with WebDAV because it is a very nice integration piece that I think a lot of people will find pretty beneficial.
To get started with the Wiki service, first turn it on. This one isn’t heavily dependent on host names (other than being able to access the server from a browser) or directory services (other than being able to authenticate users, but local accounts are perfectly functional) and it doesn’t require the Websites service to be running as well. One should always have good working directory services and host names, still…
To enable the service, open the Server app and click on Wiki in the list of SERVICES in the List Pane.
There are two configuration options. The first is to select who is able to create wikis. Use the “Wikis can be created by” drop-down list to select “all users” if anyone with an account on the server should be able to create a wiki or “only some users” to bring up the Wiki Creators screen.
If only some users can create new wikis, use the plus sign (“+”) at the Wiki Creators screen to add users and/or groups to the list of users that can create wikis. Click on OK when all users and groups that can create wikis are added. In a school I would imagine that only teachers or IT staff would be able to create wikis. Once a wiki is created, pages inside the wiki can still be created by non-wiki creators.
The other option available is the handy dandy WebDAV interface to the wikis. When you enable this option, you can connect to a server from macOS or iOS via WebDAV and access files in each wikis document repository. To be clear, this option doesn’t provide access to the user documents, but does provide access to the wiki documents. We’re going to check the box for “Enable WebDAV access to Wiki files” and then click the ON button.
Once the service starts, click on the View Wiki link in the Wiki workspace in Server app.
Here, click on the Log in button and enter a user with access to the server, preferably one who can create wikis.
At the Wikis page, you will then see a list of all wikis you have access to. Note that the previous screen showed one wiki and now we see two. That’s because one of the wikis has permissions that allow “All unauthenticated users” access to the wiki, which we’ll describe shortly. The first thing most administrators will do is create a wiki. To do so, click on the plus sign (“+”) icon on the web page and at the resultant screen, click on New Wiki.
At the “Create a new wiki” prompt, provide a name for the wiki and a brief description for it.
Click on Continue.
At the Set permissions screen, enter each user or group to provide access to edit and view wiki pages. Here, you’ll have the options for Read & Write (users can view and edit pages in the wiki), Read only (users can only view the contents of your pages) and No access (users have no access to the wiki). There is a group for All logged in users, which includes every user with access to the server and another for All unauthorized users, which includes guests to the server. Once you’ve given the appropriate permissions, click on Continue.
Note: You don’t have to get this perfect now as you can always edit these later.
At the Set Appearance screen, you can choose an icon for the wiki (shown in the wiki list and when you open the wiki) as well as a color scheme for the wiki. Choose the appropriate appearance for your wiki (again, you can always change this later) and then click on the Create button.
Once the setup is finished, you’ll see the Setup complete modal. Here, you can click on Go to Wiki button.
Once you’ve created your first wiki, let’s edit it and customize the content. To do so, click on it from the list of available wikis. Click on the cog-wheel icon and then Wiki Settings… to bring up the Wiki Settings page.
Here, you’ll see the previously entered name and description as well as options to enable Calendar (only available if Calendar Server is running on the server) and Blog, which enables a blog service for the wiki (wiki administrators can post blog entries to the wiki). Click on Appearance.
Here, you will have the previous two options as well as the ability to upload a banner (which should be 62 pixels high) and background for each wiki.
Click on Permissions. Here, you’ll see the permissions previously configured as well as options to configure who can comment on articles (nobody disables comments completely) in the wiki and whether comments require approval (moderation).
Click on Save. Now, let’s edit the splash page. To do so, click the pencil icon in the top navigation bar.
At the edit screen, the top nav bar is replaced by a WYSIWIG editor for managing the page. Here you can justify, link, insert media and of course edit the text you see on the screen. I recommend spending some time embedding links, inserting tables, making text look like you want it to and editing the content to reflect the purpose of the wiki. Click Save when you’re done. Click the pencil again to edit it, and let’s create a new wiki page. Keep in mind that link wikipedia, each page should be linked to from other pages in the order they should be read. Unlike most wikis, there’s actually an index page of all the articles, which can come in handy.
From the edit page, to create a new page and link to it, enter some text (or lasso some) that you’ll use as the link to access the new page you’re creating. Then click on the arrow and select “New page.”
Note: Use Enter URL to link to an existing page or an external website, instead of creating a new page.
At the New Page screen, provide a name for the new page (the lasso’d text automatically appears as the Page Title) and click on the Add button.
Click Save and then click on the newly created link. You can now edit the new page the same way you edited the previous pages. Click on the disclosure triangles in the right sidebar to Comment on articles, link articles to related articles, tag articles and view editing history.
Now for the fun part. Click on Documents. Here, you’ll see the pages you already created. Click on the plus sign and select the option to Upload File to the wiki.
At the Upload File dialog, click on Choose File and then select a file to upload.
Click Upload when selected.
Then from the Finder of a macOS client, use the Go menu to select “Connect to Server”. Enter the name or IP of the server and then click on Connect.
Assuming you can access the server, you should then be prompted for a username and password. Enter it and click Connect. Eventually, the file(s) will display (it can take awhile according to your network speeds and how many files are in the directory). You can connect to this same screen through an iPad using a 3rd party WebDAV client or the build in options in Pages.
Managing wikis is as easy as its ever been, with the new options for appearance being a nice add-on. Active Directory integration is as easy as binding the server to Active Directory and using the accounts listed in Permissions of pages.
Now that iOS devices can edit wikis and many of the traditional word processing options are available in the wiki editor, consider what the Wiki can be. Could it replace text editing apps for iOS? Could the Wiki allow for more collaborative documents than a Word or other document editor? Could it keep from getting eaten like the rest of the homework? Could the comments in the Wiki be a good way for teachers to have students write responses to materials? Could the Wiki and the document management features allow your workers to access human resources documents and employee manuals? I know plenty of tech firms that use wikis to track information about the systems they manage.
Once you have all of this information, upgrading can seem downright scary. But fear not, there’s Carbon Copy Cloner. And once you’ve cloned, there’s wikiadmin. When doing an upgrade in place, the Wiki service is pretty straight forward to upgrade, but in many cases, due to aging hardware, wiki services are moving from an older computer to a newer computer. This can be done in one of two ways. The first is to “migrate” the data by copying the Collaboration folder onto the new system. The second is to “export” and “import” the data. I usually recommend doing a migrate where possible, so we’ll start with that method.
Note: Before getting started, make sure that the directory services side of things is good. If a user or group lookup for an object that owns, edits or has commented on a wiki fails then that wiki probably shouldn’t be migrated. Use the dscl or id commands to confirm that lookups are functioning as intended.
To migrate wikis from one server to another, first copy the Collaboration directory to the new server. In this example, the directory has been dropped onto the desktop of the currently logged in user. To migrate the data once copied, use the wikiadmin command, along with the migration option. The option requires the path to the Collaboration folder, defined with -r, as follows:
sudo /Applications/Server.app/Contents/ServerRoot/usr/bin/wikiadmin migrate -r ~/Desktop/Collaboration
When moving wikis, you can take the opportunity to get rid of a few you don’t want (such as that test wiki from way back when). Or administrators may just choose to move a single wiki to a new server in order to split the load across multiple hosts. When doing so, use the same command as earlier, along with the name of each wiki that is being moved, along with the -g option. For example, if moving the Legal wiki:
sudo /Applications/Server.app/Contents/ServerRoot/usr/bin/wikiadmin migrate -r ~/Desktop/Collaboration -g Legal
The second way of moving wikis around is to export and then import them. To do so, first export wikis on the old server, using the wikiadmin command along with the export option, which requires an –exportPath option and needs to be done, on a wiki-by-wiki basis. So to export that Legal wiki to a file called LegalWikiTMP on the desktop:
sudo /Applications/Server.app/Contents/ServerRoot/usr/bin/wikiadmin export -g Legal --exportPath ~/Desktop/LegalWikiTMP
Next, copy the wiki to the new server and import it, using the import option along with –importPath to identify where the file being imported is located. Using the same location, the command would then be:
sudo /Applications/Server.app/Contents/ServerRoot/usr/bin/wikiadmin import -g Legal --importPath ~/Desktop/LegalWikiTMP
Note: The ability to import a wiki also allows for an API of sorts, as you can programmatically create wikis from other sources. The ability to export also provides a way to move into another wiki tool if you happen to outgrow the options provided in Server and need to move to something more robust.
There is another way to move wikis, using pg_dump, copying the data and then using pg_restore to import the data once you’ve created the tables. This way is, in my opinion, the last resort if the standard wikiadmin commands aren’t working. In my experience, if I’m doing the migration this way then I’ve got other, bigger issues that I need to deal with as well.
These commands work best when the wiki service has been started so that the databases are fully built out. To start the wiki service from the command line, use the serveradmin command instead of the wikiadmin command. The serveradmin command is used with the start option and then wiki is used to indicate the wiki service, as follows:
sudo /Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin start wiki
The service can also be stopped, swapping out the start option with a stop option:
sudo /Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin stop wiki
In a few cases (this is the main reason I’m writing this article), the attachments to wikis don’t come over during a migration. To migrate the files that are used for QuickLook, downloading attachments, etc, use the serveradmin command to locate the directory that these objects are stored in:
sudo /Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin settings wiki:FileDataPath
The output identifies the directory where these objects are stored. Placing the contents in the same relative path as they are to the output of the same command on the target server usually results in restoring them. Once moved, use the fixPermissions option to repair the permissions of any files from the source (if any changes to account IDs are encountered such as an export/import rather than an archive/restore in OD this can lead to odd issues:
Also use the rebuildSearchIndex option with the wikiadmin command to fix any indexing, once the permissions have been repaired:
And finally use resetQuicklooks to clear any cached Quicklook representations of objects that have been inserted into a wiki and might not display properly using Quicklook (you know you might need to do this if they look fine when downloaded but look bad with Quicklook even though QuickLook on the server can view the files just fine):
When done properly the migration can take awhile. Keep in mind that every tag, every article, every edit to every article and basically everything else is tracked inside the tables that you’re moving. While there might not be a ton of data in the Collaboration directory or in an export, all of the data needs to go to the right location. This can take a little time in environments that have a lot of articles, even if they’re really short articles…

When I was speaking at MacADUK, I asked Tom Bridge about starting a podcast. He’s got a great voice, and I thought he’d be a great co-host. Before we were able to get to that when we got home, Adam Codega, independently of the conversation I’d had with Tom, dropped a note on Twitter to see who else might be interested in doing a Podcast. A few people responded that they’d be interested in also jumping in on a new Podcast. Over the next few weeks, decisions were made that the podcast would be hosted as a part of MacAdmins.org, the format, the hosting location, and lots of other really cool stuff. And some of us got together and recorded the first episode. And then, last night, we recorded the second episode just in time to get that into editorial before Episode 1 is released.
And soooooo, episode 1 is out! It includes Tom Bridge, Emil Kausalik, Adam Codega, and myself. We also have an interview with some of the organizers from the Penn State Mac Admins conference, which I wasn’t able to sit in on, but find just fantastic. And Tom did some of the editing. Aaron Lippincott (@dials-Mavis) did a lot of work on the mastering and deserves lots of credit there (he made everyone sound way betterer). And John Kitzmiller did a lot of work on the domain and website and DNS type of stuff, as well as helping with hosting of the podcast assets as well. And Adam’s done a lot of work on the back end linking things together, so a great team effort.
The next episode also features Pepijn Bruienne and Marcus Ransom (who I lovingly decided we should call the He-Man of the Mac Universe) and covers the latest iOS 9.3 release, as well as some information about the Classroom app. So stay tuned for that, but click below to give the episode a listen, or find on iTunes once it appears (and I’ll post a link to that once we can).
Overall, I’m really stoked to get this thing going, and that the group has built a great system for future episodes, that should be sustainable for many, many episodes. I’m also really stoked to be able to get to work with this specific group – I’m a big fan of everyone, and I look forward to many episodes to come! So follow on Twitter at @MacAdmPodcast
and feel free to let us know if you’ve done something awesome and we should mention it or interview you!
