add-apt-repository ppa:nginx/$nginx

Install Ngnix:

aptitude update
aptitude install nginx

See Nginx install Ubuntu PPA for more details.

FastCGI

Now install FastCGI for Nginx:

aptitude install fcgiwrap spawn-fcgi

See Linode perl-fastcgi on Ubuntu

Install Foswiki

wget http://sourceforge.net/projects/foswiki/files/foswiki/1.1.4/Foswiki-1.1.4.tgz
mkdir /var/www
tar vfx Foswiki-1.1.4.tgz
mv Foswiki-1.1.4 /var/www/foswiki

aptitude install rcs libarchive-tar-perl libarchive-zip-perl libcgi-session-perl \
libdigest-sha-perl libdigest-sha1-perl libhtml-entities-numbered-perl \
libhtml-parser-perl libhtml-tree-perl

Configure Ngnix

Remove the ‘default’ site configuration by deleting the symlink:

rm /etc/nginx/sites-enabled/default

Create ‘/etc/nginx/sites-available/foswiki.conf’ with this content:

server {
    listen       80;
    server_name  foswikiserver;

    set $foswiki_root "/var/www/foswiki";
    root $foswiki_root; 

    location / {
        root $foswiki_root;
        index index.html;
    }

    location /bin/configure {
        allow 127.0.0.1;
        allow YOUR_IP_HERE_!!!;
        deny all;
        gzip off;
        fastcgi_pass unix:/var/run/fcgiwrap.socket;
        fastcgi_split_path_info ^/foswiki(/bin/configure)(?:\.pl)?(.*);
        fastcgi_param  SCRIPT_FILENAME  $foswiki_root$fastcgi_script_name;
        fastcgi_param  PATH_INFO $fastcgi_path_info;
        include fastcgi_params;
    }
}

Note: Replace “YOUR_IP_HERE_!!!” with the IP-Address of your workstation to allow you the access to the configuration page.

Now enable the new site:

ln -s /etc/nginx/sites-available/foswiki.conf /etc/nginx/sites-enabled/

Restart Ngnix:

service nginx restart

Note: My Foswiki server called ‘foswikiserver’ you have to replace this with your Domainname like ‘www.myfoswiki.com’.

Configure Foswiki

Now open ‘http://foswikiserver’ in your browser:

Select ‘Configure Foswiki’ and make your configuration settings.

Now go to ‘Extensions’ and select ‘Install and Update Extensions’.

Search the ‘FastCGIEngineContrib’ Extension and install it.

More informations see: Foswiki configuration on Nginx

Configure Foswiki FastCGI

Install the requires package:

aptitude install libfcgi-perl

Now create a small upstart script to run foswiki FastCGI.

Create ‘/etc/init/foswiki.conf’:

# Foswiki - Service Upstart script #

description "foswiki"
author "Mogilowski Sebastian"

start on started networking
stop on runlevel [!2345]

env FOSHOMEDIR=/var/www/foswiki
env FOSSOCKDIR=/var/run/nginx
env FOSUSER=www-data
env FOSGROUP=www-data
env NUMCHILDS=25

respawn

pre-start script
    chdir $FOSHOMEDIR/bin
    mkdir $FOSSOCKDIR                              ||true
    chown $FOSUSER:$FOSGROUP $FOSSOCKDIR           ||true
    chmod 0755 $FOSSOCKDIR                         ||true
end script

script
  cd $FOSHOMEDIR/bin

  exec su -s /bin/sh -c 'exec "$0" "$@"' -- $FOSUSER ./foswiki.fcgi -n $NUMCHILDS -l $FOSSOCKDIR/foswiki.sock

end script

Now you can start the foswiki service:

service foswiki start

Now extend the Ngnix configuration ‘/etc/nginx/sites-available/foswiki.conf’

server {
    listen       80;
    server_name  foswikiserver;

    set $foswiki_root "/var/www/foswiki";
    root $foswiki_root; 

    location / {
        root $foswiki_root;
	rewrite ^/?$ http://foswikiserver/bin/view.pl/Main permanent;
    }

    location /bin/configure {
        allow 127.0.0.1; # localhost, you may want to omit due to security considerations.
        allow YOUR_IP_HERE_!!!;
        deny all;
        gzip off;
        fastcgi_pass unix:/var/run/fcgiwrap.socket;
        fastcgi_split_path_info ^/foswiki(/bin/configure)(?:\.pl)?(.*);
        fastcgi_param  SCRIPT_FILENAME  $foswiki_root$fastcgi_script_name;
        fastcgi_param  PATH_INFO $fastcgi_path_info;
        include fastcgi_params;
    }

    location /bin/ {
           gzip off;
           fastcgi_pass             unix:/var/run/nginx/foswiki.sock;
           fastcgi_split_path_info  ^(/bin/\w+)(.*);
           fastcgi_param            SCRIPT_FILENAME $foswiki_root/$fastcgi_script_name;
           fastcgi_param            PATH_INFO       $fastcgi_path_info;
           fastcgi_param            SCRIPT_NAME     $fastcgi_script_name;
           include fastcgi_params;
       }

    location ~ (^/lib|^/data|^/locale|^/templates|^/tools|^/work) {
        deny all;
    }

    if ($http_user_agent ~ ^SiteSucker|^iGetter|^larbin|^LeechGet|^RealDownload|^Teleport|^Webwhacker|^WebDevil|^Webzip|^Attache|^SiteSnagger|^WX_mail|^EmailCollector|^WhoWhere|^Roverbot|^ActiveAgent|^EmailSiphon|^CrownPeak-HttpAgent|^$) {
        rewrite .* /404.html break;
   }
}

Note: Remember to replace “YOUR_IP_HERE_!!!” with the IP-Address of your workstation to allow you the access to the configuration page and to replace ‘foswikiserver’ with your servername.

Last step is to reload Nginx webserver:

service nginx reload

Open foswiki in your browser with ‘http://foswikiserver’

How To Change the Default Storage Repository to EXT3

Hardware

IBM Blade HS21
2x Intel(R) Xeon(R) CPU E5540  @ 2.53GHz
16 GB RAM
LSI SAS 1064 with 2 SAS Disc with Raid 1

Software

XenServer 5.6 SP2

Virtual Machines

Ubuntu VMs (64-Bit) with latest XenTools installed (1 CPU per VM and 1024 MB RAM)

Testsoftware

bonnie++

(More Informations)

The Test

I run every test 3 times and used only the last two results. For example with 3 virtual machines i run bonnie++ 3 times on every virtual machine at the same time and stored the last 2 results of every virtual machine. (values tab in the table) I sum this 6 results and than divide it by 6. (summary tab in the table).

Download the OpenOffice table here: Xen Performance Test (303.59 kB)

Note: The data shows only the values for a single virtual maschine. For example the CPU Usage on the last tab in the table shows the CPU Usage of ONE virtual machine. (Multiplicate it with the amount of virtual machines and the difference between PLAIN is the virtualization overhead).

[Show as slideshow]

My result is, that there is no performance difference between LVM and EXT filesystem on the XenServer storage repository. But with EXT you can give the virtual maschines more storage as you physically have in your server.

Example:

A new theme is online.
It’s a modified version of black-with-orange.

Now with a little bit more colors and more cats.

I hope everything works for you. If not please let me know !

Green Prompt for your user

Edit ”~/.bashrc” and change:

#force_color_prompt=yes

to:

force_color_prompt=yes

To change it for all new users make the same in ”/etc/skel/.bashrc”.

Red Prompt for root

Edit ”/root/.bashrc” and change ”force_color_prompt=yes” like for your user.

Now change the color to red. Search this line:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

and change it to:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

Note: For this change to take effect, you must log out then log in again.

Debian (older versions)

Green Prompt for your user

Open ”~/.bashrc” and append:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

Red Prompt for root

Edit ”/root/.bashrc” and append:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]$ '

Easy way to test a lot of other linux distributions or play around with some system utilities

You can install the following OS and System utilities with unetbootin.

Operating Systems

* Ubuntu		* Fedora
* Debian		* PCLinux OS
* Linux Mint		* Sabayon Linux
* openSUSE		* Gentoo
* Arch Linux		* MEPIS
* Damn Small Linux	* Zenwalk
* SliTaz		* Slax
* Puppy Linux		* Dreamlinux
* gNewSense		* Elive
* FreeBSD		* CentOD
* NetBSD		* Mandravia
* Frugalware Linux	* xPUD

System utilities

* Parted Magic
* SystemRescueCD
* Super Grub Disk
* Dr. Web Antivirus
* F-Secure Rescue CD
* Kaspersky Rescue Disk
* Backtrack
* Ophcrack
* NTPasswd
* Gujin
* Smart Boot Manager
* FreeDos

1. Installation

aptitude install unetbootin

2. Create Live USB Stick

Open UNetbootin from your start menue:

Select Distribution and Version with the Selectbox on the top. I choose Ubuntu 11.10 for example.

Make sure you have selected the correct USB-Drive at the bottom of the window.

UNetbootin now download the selected Operating System and install it on the Stick.

3. Boot from USB

Unmount the stick and reboot your system. Make sure you are booting from USB-Drive.

Note: UNetbootin is available for Linux, Windows and MacOS !

4. Links

* http://unetbootin.sourceforge.net

1. Use cryptsetup

1.1 Install cryptsetup:

aptitude install cryptsetup

1.2 Setup cryptsetup volume:

Unmount the stick and format it:

umount /dev/usb1
cryptsetup luksFormat /dev/usb1

Type “YES” an choose a password.

Open the crypt partition:

cryptsetup luksOpen /dev/usb1 crypt_USB

Create new Filesystem and mount it:

mkfs.ext4 /dev/mapper/crypt_USB
mount /dev/mapper/crypt_USB /mnt

Remove the drive:

umount /dev/mapper/crypt_extern
cryptsetup luksClose crypt_extern

1.3 Mount cryptsetup:

Now reattach the stick. Ubuntu ask you for the password (LUKS passphrase) you choose and mount the crypted partition.Nun den Stick wieder einstecken. Ubuntu fragt nun nach dem Passwort (LUKS passphrase) welches man vorher festgelegt hat und mountet die verschlüsselte Partition

Note: “/dev/usb1″ is may be different on your System.

2. Use TrueCrypt

2.1 Installation:

Download tar.gz from truecrypt.org

Extract and run setup script:

tar vfx truecrypt-7.1-linux-x64.tar.gz

./truecrypt-7.1-setup-x64

Select “Install TrueCrypt” and accept the licence terms.

Press enter to exit the setup tool.

2.2 Setup TrueCrypt Volume

Run TrueCrypt from your Start Menu and select “Create Volume” now choose “Create a volume with a partition/drive” and press “Next”.

Choose “Standard TrueCrypt volume” select a Volume and select your preferred encryption options:

Now enter a password for your usb stick, enable the large file support and select the filesystem type. (I take ext4)

If you want to use your usb stick on other operating system than linux you can enable the cross-platform support. But you have to choose a filesystem type which windows and/or macos understand in the previous step.

Now make some random moves with your mouse and select “Format”. (This will take a few minutes)

2.3 Mounten:

Run TrueCrypt from your Start Menu.

“Select Device” and select your TrueCrypt Partition:

Press “Mount” and enter your password.

Device “truecrypt1″ is now mounted on your system and ready to use.
