Apache Named VirtualHosts with wildcards

I want to map www.example.com to a specific virtual host and then I want all other subdomains of example.com to go to another virtual host.

To do this I created these hosts:


  ServerName www.example.com



  ServerName example.com
  ServerAlias *.example.com

Now the selection of which host is served seems rather random. If I restart apache sometimes I will get one host and other times another.

What am I doing wrong?

Thanks!

Update:

If I run apache2ctl -S on this configuration I get this outpu:

VirtualHost configuration:
wildcard NameVirtualHosts and _default_ servers:
*:80                   is a NameVirtualHost
         default server www.example.com (/etc/apache2/sites-enabled/dev:3)
         port 80 namevhost www.example.com (/etc/apache2/sites-enabled/dev:3)
         port 80 namevhost example.com (/etc/apache2/sites-enabled/dev:22)

After much digging around I decided to disable the mono applications that I had running and low and behold it started serving files from the correct site. They did need to be entered in the order:


  ServerName example.com



  ServerName www.example.com

as suggested by Wizard.
To get my mono apps working I used "MonoAutoApplication enabled" within each virtual host. However I am not sure that this is the best option as on the mono site it says you shouldn't use auto hosting for asp.net mvc apps (which is what I am using). So far I can't see the downside though.

Answer

Update: * is valid syntax but not necessary. You can find out more here.

This will work though.


   ServerName example.com




    ServerName www.example.com

The first directive will match everything that is not explicitly defined elsewhere.

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

ubuntu - Monitoring CPU, Mem, disk, on a single server

I've been looking for a simple starter solution for monitoring my [currently] single server hosted solution. Other than Nagios and similar, are there other good (simple) solutions people are using? Answer Everything depends on what you want. For example Munin is very simple, you can install and configure it in less then 10 minutes (on one server), it can sends alarms, make graphs from monitoring cpu, mem. apache connections, eaccellerator, disk io and many many more (it has many plugins). But if you are planning in future get some more machines, munin may not be enough. For example in munin you cant monitor state of individual processes, can't monitor changes in files (for security purpose). So if you wanna only see what is the utilization of basics parameters on your server and don't plan to buy some more servers Munin is what you are looking for, but if you wanna be alarmed when some of your service is down, take more control on what is happeninig on...

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...
