Bring OER contents to no-internet place

Rachel-pi makes OER (Open Education Materials) available on Raspberry Pi. This tiny computer can contain an incredible amount of contents, such as the Khan Academy, the Gutenberg Project collection, textbooks, and encyclopedias, and provides the service as a web server. Since you can access the local Internet address after installation, it is possible to use several people at the same time.

Because the computer capability is not high, it seems that 10 or more concurrent users are hard to use concurrently, and in such case, it would be better to use the general computer as a web server. Anyway, when you put these contents on a Raspberry pi, which usually prices about 30 $, it becomes a treasure of contents.

The installation method is provided at http://rachelfriends.org/rachel-pi-howto.html. First, I downloaded the image file to install by using ftp.

I needed to save the downloaded file to the 64G SD memory card as an image. Since I have a Mac, I could save the image to a 64G SD memory card by running the following command:

“diskutil list

diskutil unmountDisk /dev/disk3

sudo dd bs=1m if=rachelpi_64xx_x.x.img of=/dev/rdisk3″

It is said that after loading the memory into the raspberry wave and booting, you can access http://10.10.10.10 on your local computer and enjoy the contents.

For first-timer .. Download Foramatter from http://www.sdcard.org/download. This is useful when formatting a memory card.

Run the Formatter and run the format command. At this time, the sd card is recognized automatically.

Run the following command on the formatted sd card to unpack the rachel image file. (Wait with patience as it will take quite a while)

Now insert the memory card into the Raspberry pi, connect to the Internet and turn on the power. Will that be it?

“[FAILED] Failed to start /etc/rc.local Compatibility” error. 🙁

I searched internet and found that I need to delete two lines from the rc.local file. https://github.com/rachelproject/rachelpiOS/issues/15

It works … but what I wiped was setting “10.10.10.10” as a local address. So I need to check the local ip address using ifconfig and access it.

I can have administrator access to change the Rachel PI screen configuration, but I found a lot of passwords. https://github.com/rachelproject/rachelpiOS/wiki/Default-Passwords

Ultimately, the password was a DB password, unlike the screen description. root / rachel

After installation, I was able to enjoy the contents as follows. success!!
