Installing mediawiki on WAMP

Building on our WAMP installation, we are now going to install mediawiki.

The first thing I’d recommend to do is to move the contents of c:\wamp\www into another directory… I just shoved the terminal thing into c:\wamp\terminal .

Now mediawiki is the software that powers wikipedia. It’s a great collaboration platform, it has built in revision control, and best of all it’s free.

It’s also VERY simple to setup, well compared to other web content platforms.

The current version is 1.16, which can be downloaded here. As things change, you may be best served by just visiting the main download site.

Since most ‘AMP’ servers are Linux based, we’ll have to get gzip & tar to extract mediawiki. It’s very easy though.

Simply type this in to extract mediawiki

Volume in drive C has no label.
Volume Serial Number is FC55-C2F4

Directory of C:\temp

12/28/2010 08:15 PM DIR ..

2 Dir(s) 7,073,234,944 bytes free

C:\temp>gzip -dc mediawiki-1.16.0.tar.gz| tar -xf –


Ok, now with mediawiki extracted we just move the contents of c:\temp\mediawiki-1.16.0 into c:\wamp\www

Now before we go on, we are going to set a password for the MySQL process. In the off chance someone is following this on a server to deploy on the internet, it’d be crazy to leave it with no password.

So left click on the WAMP system tray icon, go to MySQL, and bring up the MySQL Console.


Just hit enter for the password as there isn’t one.

Next follow this SQL statement to set the password for the root user to password. Or select your own better password.

mysql> use mysql;
Database changed
mysql> update user set password=PASSWORD(“password”) where User=’root’;
Query OK, 3 rows affected (0.05 sec)
Rows matched: 3 Changed: 3 Warnings: 0

Now restart the mysql service, by clicking on the system tray icon, then mysql, service then ‘restart service’. If you don’t do this the password change will not take effect!

With that out of the way, it’s time to configure mediawiki. Simply open up a web browser to the following location:


And you should see something like this:


Click the setup link, and let’s walk through the options…

First is the wikiname. I’m just going to call mine ‘test wiki’. Put in your own contact email, so that mediawiki will email YOU if anything is going on… I left the language in English, and left the license alone. The next important thing to do is to select a Admin username, and password. This is all up to you. Just remember that the Username is CaSe SeNsItIvE!!!

Leave the caching off.

The next section is for the email notifications, I just left those as default.

The final thing to configure is the database.

Since we are going to keep this simple, just set the DB username to root, and put in the password you configured earlier in the MySQL Console. Next check the ‘superuser account’ box, and specify root and the password again.

You can now click the Install MediaWiki button!

You’ll see some information printed on the page, and if everything goes according to plan, you’ll get the message:

Installation successful! Move the config/LocalSettings.php file to the parent directory, then follow this link to your wiki.

You should change file permissions for LocalSettings.php as required to prevent other users on the server reading passwords and altering configuration data

So simply copy the file c:\wamp\www\config\LocalSettings.php to c:\wamp\www\

then simply click the following link to be taken to your personal wiki:



And that should take care of it!

Proxmox VE

Well frankly I’ve been majorly disappointed with Microsoft’s latest offerings in the world of virtualization. Frankly it’s been one BIG step backwards in terms of management.

I mean check this well meaning blog on how “easy” it is to setup remote management. And of course for the most part it NEVER works.

I know this must be a major news flash to Microsoft but you see virtual servers are like mainframes. The zone 0 OS must be able to stand on it’s own, and have just enough to bootstrap the hypervisor and allow itself to be managed in a stand alone fashion. After all if it were in a domain, where do you think those domain controllers are? Yep they are Virtual machines! And how do you ‘manage’ a domain resource with no DC’s? The whole 2008 Hyper-V is a BIG miscalculation on Microsoft’s part. I hope they wake up and notice how they had a good thing and have destroyed it.

All this nonsense sent me searching for an alternative which I’m pretty sure I found a great blend of system emulation, and something like SUN containers for Linux. There is even a Debian etch based quick install version called Proxmox which incorporates KVM (The new Linux hypervisor) and OpenVZ. And of course it’s FREE!

The cool thing is that the main management works on a web page, the consoles can be controlled via a VNC viewer that uses JAVA, and it’s VERY quick to setup.

The system emulation KVM uses the core devices from Qemu so a lot of Qemu virtual machines will “just work” if you copy them over. If you are installing an OS onto the virtual machine the ‘easy’ way is with the physical CD, you can use ISO images, however they are awkard to use. You have to flag the VM to pause on startup switch over to the monitor page and issue the following command:

change ide1-cd0 /directory/isoimage.iso

then tell the emulator to start up with the ‘c’ command which will continue from the pause…. Yeah I know it’s not terribly eligant.

On the OpenVZ front, it’s FAST as there is no real emulated IO it’s native. So I decided to use the wiki template and setup a wikipedia mirror at home. If anyone feels as brave you too can find instructions here:

These are some of the table times to load:

1.2G template-link Query OK, 48,885,222 rows affected (50 min 7.08 sec)
68k user_groups Query OK, 3,947 rows affected (0.11 sec)

Even the ‘longest’ part here with the 270 million records took six hours… Not too bad! That’s still 12,122.88 TPS!

Also as a tip for anyone else crazy enough to do a sizable mediawiki (like wikipedia) or any single server wiki look to this page.

The upshot is that by loading this APC
extension into PHP and mediawiki load times for my cached site went from 2-5 minutes to 1-10 seconds.

The OpenVZ portion has various application templates that can be loaded into the zones from CentOS, Debian, Ubuntu, to pre configured applications like the media wiki and a few others.

If anything I’d say that proxmox is what I was hoping Microsoft’s Hyper-V could have been. A container version of windows with easy remote admin along with some system emulation could have made things MASSIVLY easier to deal with. It’s a shame they decided to go with this bizarre WMI based thing.
