This post should give an overview on which ARM powered devices GNU/Linux runs and also gives a hint how good it is supported on the respective device. Also Android runs a Linux kernel but does not give a general purpose computing experience to the user and does not host GNU tools.
Here is a list of boards and devices which are affordable for
the home user – devices for industrial use tend to be just too expensive.
Debian GNU/Linux on NAS Devices and the Plug Computer
http://www.cyrius.com/ Get more infos here
Mostly based on Marvells Orion and Kirkwood platform.
Debian has a long history on NAS devices e.g. from QNAP
and is stable and good supported. Also the popular but discontinued
NSLU2 device runs perfectly Debian and other Linux Distributions.
Debian GNU/Linux on the Raspberry Pi ARM11
The main Raspberry Pi Distribution is called Raspbian and is based on Debian.
Raspbian has good support for the popular Raspberry Pi hardware, but it lacks support for the onboard graphic accelerating capabilities for Xorg.

FW: Install nginx on Centos 6.x
http://www.cyberciti.biz/faq/install-nginx-centos-rhel-6-server-rpm-using-yum-command/
Step #1: Install nginx repo
# cd /tmp
# wget http://nginx.org/packages/centos/6/noarch/RPMS/nginx-release-centos-6-0.el6.ngx.noarch.rpmnginx-release-centos-6-0.el6.ngx.noarch.rpm
# rpm -ivh
Step #2: Install nginx web-server
# yum install nginx
Step #3: Turn on nginx service
# chkconfig nginx on
How do I start / stop / restart nginx web-server?
# service nginx start
# service nginx stop
# service nginx restart
# service nginx status
# service nginx reload
Step #4: Configuration files
- Default configuration directory: /etc/nginx/
- Default SSL and vhost config directory: /etc/nginx/conf.d/
- Default log file directory: /var/log/nginx/
- Default document root directory: /usr/share/nginx/html
- Default configuration file: /etc/nginx/nginx.conf
- Default server access log file: /var/log/nginx/access.log
- Default server access log file: /var/log/nginx/error.log
To edit the nginx configuration file, enter:
# nano /etc/nginx/nginx.conf
Set or update worker_processes as follows (this must be set to CPU(s) in your system. Use the lscpu | grep ‘^CPU(s)’ command to list the number of CPUs in the server)
worker_processes 2;
Turn on gzip support:
gzip on;
Edit the file /etc/nginx/conf.d/default.conf, enter:
# nano /etc/nginx/conf.d/default.conf
Set IP address and TCP port number:
listen 199.241.137.179:80;
Set server name:
server_name vps.zhenglei.net;
Start the server:
# service nginx start
Verify that everything is working:
# netstat -tulpn | grep :80
# ps aux | grep nginx
Firewall configuration: Open TCP port # 80
Edit the file /etc/sysconfig/iptables, enter:
# nano /etc/sysconfig/iptables
Add the following lines, ensuring that they appear before the final LOG and DROP lines for the INPUT chain to open port 80:
-A INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT
Save and close the file. Finally, restart the firewall:
# service iptables restart
