Introduction
Objectives
This project aims to create a local file system server using ARM Platform. It is very useful for this purpose for the next reasons:
-ARM is designed for low power consumption. This server should be connected to power supply all the day, if you use this architecture you can lower your electric bill.
-ARM-Embedded is usually cheaper than a X86-Embedded processor.
-If you have a good internet broadband, is not difficult to configure your server to accept external http request.
-Your data are 100% under your control, other services you don't know where are your files.
-Commercial services offer premium accounts with extra hard disk space, in your server you can use all the space as your HD or SD supports.
When you finish this how-to, you will have your own local web service similar than Dropbox and SugarSync. Your service will powered by Owncloud.org software. I used for this tutorial Owncloud 3 alpha 1 release to prove all new characteristics, but you can follow this tutorial using the stable version. There characteristics are: File management, WebDAV access, sharing, music streaming, calendar, contacts, users & groups, image gallery, online text editor, online task manager and bookmarks. For more information go to Owncloud.org page.
Limitations
When i finished this project, i tested the system performance making some tests. After this i did the next conclusions:
- If you upload a folder with more than 100 files, i recommend that you compress it before the upload.
- Don't compress via Web a folder large than 100 MB, use WebDAV for download it.
- Don't upload more than 750 MB via Web, use WebDAV for this purpose.
- The Web uses HTML5 technology, it tested with Firefox 7 and Chromium 14 browser and mobile phone with IOS 4.3.3. Older browsers maybe have problems.
Hardware Used
The hardware used for this project is:
- IGEPv2 Board Revision C with 1 GHz Processor and 512MB Ram.
- 5 V power supply.
- MicroSD card 2GB at least with SD card adapter.
- IGEPv2 Serial Debug cable, it isn't necessary later.
- Ethernet cable.
- Switch or Router.
- External USB Hard Disk with USB cable.
Software Used
I used the following software:
- Gparted
- Igep-x-loader-2.1.0-3.tar.bz2
- LAMP
Installing Linaro Headless
Using this tutorial(microSD) and this other(IGEPxloader) to install Linaro Headless in your SD card. It runs well with the software detailed above. You can compile the IGEPxloader and Kernel, but is not necessary.
NOTE: Use FAT16 for boot partition and EXT3 for rootfs partition.
Create a new file into the boot partition named igep.ini with these content and save the file.

NOTE: I recomend change MAC adress.
Set up internet connection
Login as root via serie, we use "vi" editor to add the following lines to the bottom of /etc/network/interfaces
auto eth0 iface eth0 inet dhcp
NOTE: Some routers give a static IP via Dhcp identifying the MAC address, others give a free IP when we send Dhcp request. Also you can configure /etc/network/interfaces to get a static IP with the following lines:
auto eth0 iface eth0 inet static address <type your address> netmask <normally: 255.255.255.0> gateway <where send Dhcp request>
Save changes and restart the system with "reboot" command.
After reboot,if you don't know private ip of your server, find it typing:
ifconfig
Search in eth0: "inet addr:X.X.X.X", where X.X.X.X is the private IP server.
Test your server connection sending a ping request:
<pre>
ping X.X.X.X
</pre>
After this, upgrade your system with "apt-get".
Installing Open SSH Server
Type login as root via serie:
apt-get install openssh-server
Change root password typing:
passwd root
Enter new password, i recommend use letter, numbers and symbols like:?¿!...
Search in eth0: inet addr:X.X.X.X, where X.X.X.X is the server private IP. We are going to prove it login as root via ssh:
ssh root@X.X.X.X
Using the password typed above, we be able to connect to server via SSH.
The next steps are not necessary use serial communication .
Creating and editing Server Users
Using root user can be dangerous, for this reason we are going to create a new user named adminserver to access server. Create new user typing:
adduser adminserver
Follow the assistant entering a password and your user data.
Once adminserver user was create, we are going to give sudoers privileges. Type:
visudo
Go to: # User privilege specification, and add below:
adminserver ALL=(ALL) ALL Defaults:adminserver timestamp_timeout=0, runaspw, passwd_tries=1
The first line says that adminserver user can access like root with sudo command.
The second line, configure some paremetres to adminserver sudo access: adminserver needs root's password to run sudo (runaspw), the password will not be remembered (timestamp_timeout) and he gets only one chance to enter it (passwd_tries).
NOTE: Is important use visudo editor because it can detect spelling errors before write sudoers file.
Installing LAMP
Apache
We are going to install Apache HTTP Server:
sudo apt-get install apache2 apache2-mpm-prefork
After installation, we are going to make some configurations:
mkdir /home/<user>/web/
We create that folder called web to store all the web files.
Now we are going to change some basic Apache configuration, edit: /etc/apache2/sites-available/default
Search line:
DocumentRoot /var/www/
Replace by:
DocumentRoot /home/<user>/web/
Search line:
Directory /var/www/ Options Indexes FollowSymLinks MultiViews
Replace by:
Directory /home/<user>/web/ Options FollowSymLinks
Search line:
AllowOverride None
Replace by:
AllowOverride all
Save and exit.
Add the following lines to the bottom of /etc/apache2/apache2.conf
ServerSignature Off ServerTokens Prod
Restart Apache:
sudo /etc/init.d/apache2 restart
Now we have a Apache with basic improved configuration.
Under construction: Explain configuration
PHP
Now we are going to install, the required packages to run Owncloud, if you want to install more Webs like Wordpress, Joomla, etc. Maybe you need install others. Type:
sudo apt-get install php5-mysql php5-sqlite php5-json php5-curl libapache2-mod-php5 libxml2 php5-cli php5-common sgml-base xml-core php5-ming libcurl3 libfreetype6 libgif4 libming1 libmysqlclient16 libsqlite0 mysql-common php5-curl php5-ming php5-mysql
Restart Apache:
sudo /etc/init.d/apache2 restart
MySQL + PHPmyAdmin
sudo apt-get install mysql-server mysql-client phpmyadmin
When we are installing MySQL, we configure it entering password for root MySQL database. Also when we are installing phpmyadmin we should choose: configure database for phpmyadmin with dbconfig-common, type root MySQL password again, type phpmyadmin password database, choose apache2 confiuration .
Restart Apache:
sudo /etc/init.d/apache2 restart
Make a simbolic link to phpmyadmin:
sudo ln -s /usr/share/phpmyadmin /home/adminserver/web/phpmyadmin
With phpmyadmin you can handle your mysql databases (managing databases, tables, fields, relations, indexes, users, permissions, etc) via web browser. It is useful if you for Owncloud or another program than uses MySQL.
Enabling Automatic Updates
Automatic updates can be used to automatically install updated packages. You can configure it to update all packages or just security packages. Install the following package:
To configure unattended-upgrades, edit:/etc/apt/apt.conf.d/50unattended-upgrades and adjust the following to fit your needs:
The double “//” serve as comments, so whatever follows "//" will not be evaluated. Coment/uncoment the repositoris that you prefe, i recommend this configuration:
Unattended-Upgrade::Allowed-Origins {
"${distro_id} stable";
"${distro_id} ${distro_codename}-security";
// "${distro_id} ${distro_codename}-updates";
// "${distro_id} ${distro_codename}-proposed-updates";
};
You can blacklisted some packeges, you can enable automatic removes, autoremove orphans packages,etc.
To set everything first create a file: /etc/apt/apt.conf.d/10periodic and edit it with your favorite editor, my configuration is:
APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Download-Upgradeable-Packages "1"; APT::Periodic::AutocleanInterval "7"; APT::Periodic::Unattended-Upgrade "1";
The above configuration updates the package list, downloads, and installs available upgrades every day. The local download archive is cleaned every week.
For more information go to here.
Set up a External HD
External HD is useful to get more space for our project. In this part we are going to set up our HD when it is connected to server.
Format your HD with a EXT3 Filesystem.
Create the following script: /etc/udev/rules.d/50-mount-external.rules:
KERNEL!= "sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"
# Import FS infos
IMPORT{program}="/sbin/blkid -o udev -p %N"
# Get a label if present, otherwise specify one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"
# Global mount options
ACTION=="add", ENV{mount_options}="relatime"
# Filesystem-specific mount options
ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},utf8,gid=100,umask=002"
# Mount the device
ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%k /media/%E{dir_name}"
# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media/%E{dir_name}"
# Exit
LABEL="media_by_label_auto_mount_end"
Stop/start the udev deamon:
/etc/init.d/udev stop /etc/init.d/udev start
Connect your HD to server. Use "mount" command to see External HD information.
/dev/root on / type ext3 (rw) none on /proc type proc (rw,noexec,nosuid,nodev) none on /sys type sysfs (rw,noexec,nosuid,nodev) none on /sys/kernel/debug type debugfs (rw) none on /dev type tmpfs (rw,mode=0755) none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) none on /dev/shm type tmpfs (rw,nosuid,nodev) none on /var/run type tmpfs (rw,nosuid,mode=0755) none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) /dev/sda1 on /media/usbhd-sda1 type ext3 (rw,relatime)
Where our HD si mounted in media folder, and its name is usbhd-sda1
Set up Owncloud.org Software
Installing Owncloud.org
Owncloud software need some packages:
For improved scanning of music files:
sudo apt-get install mp3info
For downloading multiple files:
sudo apt-get install zip
For the OpenID plugin
sudo apt-get install curl libcurl3 libcurl3-dev php5-curl
This how-to uses the lastest release of Ownlcoud but if you use stable version it would be similar. Download Owncloud in your root Apache folder.
sudo apt-get install wget cd /home/adminserver/web/ wget http://gitorious.org/owncloud/owncloud/archive-tarball/master
Uncompres it:
tar -zxvf master
Make Root file folder in External HD:
cd /media/usbhd-sda1 sudo mkdir DATA sudo chown -R www-data:www-data DATA
Make ownCloud directory accessible to Apache:
cd /home/adminserver/web/ sudo chown -R www-data:www-data owncloud-owncloud/
Open your web browser and finish your Owncloud instalation. Go to: http://<IP PRIVATE SERVER>/owncloud-owncloud/ Put your personal information and select MySQL Database. once finish, click Finish Setup.
