Software Setting Guide for CloudShell-2

This is step-by-step guide based on Ubuntu 16.04.2 OS image for CloudShell-2 software environment.

0. Download Ubuntu image [On HOST PC]

$ wget http://deb.odroid.in/trial_4.9/ubuntu-16.04.2-mate-odroid-xu4-20170222.img.xz
$ wget http://deb.odroid.in/trial_4.9/ubuntu-16.04.2-mate-odroid-xu4-20170222.img.xz.md5sum
$ md5sum -c ubuntu-16.04.2-mate-odroid-xu4-20170222.img.xz.md5sum
ubuntu-16.04-server-odroid-xu3-20161028.img.xz: OK
$ unxz ubuntu-16.04.2-mate-odroid-xu4-20170222.img.xz

1. Insert micro SD card to micro SD card slot in your PC. (* If your HOST PC does not have micro SD card slot, then you need micro SD card reader.) [On HOST PC]

2. Flash Ubuntu image to micro SD card. [On HOST PC]

$ dd if=ubuntu-16.04.2-mate-odroid-xu4-20170222.img of=</dev/path/of/card> bs=1M conv=fsync
$ sync

3. Insert micro SD card to micro SD card slot in ODROID-XU4. [On ODROID-XU4]

4. Power on the CloudShell-2.

* NOTE: You need USB-UART Module Kit or HDMI cable + USB keyboard to access ODROID-XU4 Ubuntu console.

5. Update the Ubuntu to latest. [On ODROID-XU4]

$ sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade 

NOTE: This step includes the hard disk formatting. If your hard disk contains important data, please backup the data before trying follow's steps.

NOTE: If you want to avoid the hard disk formatting. Please use the JBOD/PM mode and skip the step 6.
On other mode (RAID 0/RAID 1/SPAN), the two hard disks are detected one logical storage. So, it is necessary to format the logical storage(/dev/sda) before using it.

6. Format the hard disks. In this example, we use the just one partition. [On ODROID-XU4]
* RAID 0/RAID 1/SPAN mode

$ sudo dd if=/dev/zero of=/dev/sda bs=512 count=1
$ sudo mkfs.ext4 /dev/sda

* PM mode

$ sudo dd if=/dev/zero of=/dev/sda bs=512 count=1
$ sudo mkfs.ext4 /dev/sda
$ sudo dd if=/dev/zero of=/dev/sdb bs=512 count=1
$ sudo mkfs.ext4 /dev/sdb

7. Create the mount points and edit /etc/fstab file for auto-mount on system start-up. [On ODROID-XU4]
* RAID 0/RAID 1/SPAN mode

$ sudo mkdir -p /media/hdd
$ sudo nano /etc/fstab

UUID=e139ce78-9841-40fe-8823-96a304a09859 / ext4 errors=remount-ro,noatime 0 1
LABEL=boot /media/boot vfat defaults 0 1
/dev/sda       /media/hdd ext4 defaults    0 1

* PM mode

$ sudo mkdir -p /media/hdd1
$ sudo mkdir -p /media/hdd2
$ sudo nano /etc/fstab

UUID=e139ce78-9841-40fe-8823-96a304a09859 / ext4 errors=remount-ro,noatime 0 1
LABEL=boot /media/boot vfat defaults 0 1
/dev/sda       /media/hdd1 ext4 defaults    0 1
/dev/sdb       /media/hdd2 ext4 defaults    0 1

8. Create a new account called “cloudshell”. This account is to access samba server. [On ODROID-XU4]
* RAID 0/RAID 1/SPAN mode

$ su -
# echo "/bin/false" >> /etc/shells
# useradd cloudshell-d /media/hdd -s /bin/false
# passwd cloudshell
(Set the password of cloudshell)
# chown cloudshell.cloudshell –R /media/hdd/
# chmod 755 -R /media/hdd/
# reboot

* PM mode

$ su -
# echo "/bin/false" >> /etc/shells
# useradd cloudshell-d /media/hdd1 -s /bin/false
# useradd cloudshell-d /media/hdd2 -s /bin/false
# passwd cloudshell
(Set the password of cloudshell)
# chown cloudshell.cloudshell –R /media/hdd1/
# chown cloudshell.cloudshell –R /media/hdd2/
# chmod 755 -R /media/hdd1/
# chmod 755 -R /media/hdd2/
# reboot

9. Install samba server. [On ODROID-XU4]

$ sudo apt install -y samba

10. Edit /etc/samba/smb.conf file. Add the following configuration options to the end of the /etc/samba/smb.conf file. [On ODROID-XU4]
* RAID 0/RAID 1/SPAN mode

path = /media/hdd
guest ok = yes
browseable = yes
create mask = 0644
directory mask = 0755
read only = no

force user = cloudshell

* PM mode

guest ok = yes
browseable = yes
create mask = 0644
directory mask = 0755
