apache virtualhosts subdomains

In this post I will show how to configure several virtual hosts on a linux machine, that will function as subdomains with their own DocumentRoots.

Goal:
  • access your site via blog.mysite.com
  • access a different site via test.mysite.com
  • allow different app to be accessable via mysite.com/app1
First you will have to redirect any traffic to a virtual host on port 80:
NameVirtualHost *:80

From now on every 'html' traffic is redirected to your following settings; and have in mind that you former DocumentRoot is overridden.
(the last caused me some troube/time)

Now set up some subdomains:


 <VirtualHost *:80>  
  ServerName blog.mysite.com
  ServerAdmin webmaster@mysite.com  
  DocumentRoot /var/www/html/blog 
 <Directory /var/www/html/blog>  
         Options Indexes FollowSymLinks MultiViews  
         AllowOverride All  
         Order allow,deny  
         allow from all  
 </Directory>  
 </VirtualHost> 

 <VirtualHost *:80>  
  ServerName test.mysite.com
  ServerAdmin webmaster@mysite.com  
  DocumentRoot /var/www/html/test
 <Directory /var/www/html/test>  
         Options Indexes FollowSymLinks MultiViews  
         AllowOverride All  
         Order allow,deny  
         allow from all  
 </Directory>  
 </VirtualHost> 



At last you have to make sure you still can access mysite.com/app1
(in a subfolder of html)


<VirtualHost *:80>  
  ServerName mysite.com
  ServerAdmin webmaster@mysite.com  
  DocumentRoot /var/www/html
 <Directory /var/www/html>  
         Options Indexes FollowSymLinks MultiViews  
         AllowOverride All  
         Order allow,deny  
         allow from all  
 </Directory>  
 </VirtualHost> 


 With these settings my server runs problemfree and I am just waiting for my fist rails app to be deployed in order to test the vhost settings for passenger.

Have fun!

rails + carrierwavve + plupload = multiple file upload

Right now I am very happy! I finished my work on creating a file upload method in rails for more than one file, altogether handled by rails sessions and as objects. First I had to learn a bit more about how rails works and I achieved that by reading a lot: books, screencasts and blogs. In this blog post I like to share what I accomplished, but without the hussle of putting code blocks in here, so watch out for bold formatted text as that is the code. My goal was to have one site with just the pure option of uploading files. All file handling would be done behind the scenes by myself logging onto my server. That said you are not going to see any fancy CRUD here. Lets start then! And dont forget to versioning your app BEFORE you try something new! [e.g. git] > rails g scaffold Photo title:string Now add carrierwave to you Gemfile and run > bundle install >rails g uploader Photo Alltogether you have model, controller, views and an uploader folder with the Ph...

debian 6 vserver - a new installation due to centOS update problem - my steps

My centOS vserver broke down after a "yum update" and even the centOS community forum could not give an answer within 24h. In my books that is poor for the almighty and stable centOS. Bare in mind that I am just a normal user of linux, no professional and definitely no expert when it comes to server, but I can read, try and share my findings: debian 6 installation steps via ssh secure your server: adduser foobar for security purposes  change /etc/sshd/sshd_conf to PermitRootLogin no now you can login as foobar and change to root via su - visudo for sudo command permissions and put this at the bottom: foobar   ALL=(ALL) ALL change hostname change hostname in /etc/hostname and in /etc/hosts reboot login via rsa key rather than password locally do ssh-keygen ssh-copy-id -i foobar@hostname... ssh now works without passwords but with keys (for easy deployment) install ruby and rails via rvm login as root always good to have: sudo apt-get install...

Stream your media to your DLNA device e.g. tv with miniDLNA on a linux machine

Recently we bought a Sony Bravia LED TV with the possibility to receive streams. It can read DLNA, which is not much, so dont fall for the certificate. DLNA means it can read MPEG-I/II and some other normal stuff. Luckily the Sony Bravia can read mkv and x256 and some other codecs. And this is something the sells people and adverbs dont tell you, so be warned not to trust the DLNA-Certificate too much, the device has to decode the media in the end. Anyway i set up miniDLNA on my laptop and now I am able to stream my media to the television. Although the process did not go that well. The problem was miniDLNA was breaking down all the time. And checking it by reading the logs etc revealed permission issues. I had to start miniDLNA as the user my files belonged to. BUT I did not use the user setting in the minidlna.conf instead I just started the daemon as the user. I could have done this with a startup script, but there were some issues with the network being set up at the sam...
