Edison Configuration

After configuring the Intel Edison via the config utility, software should be installed:

SD Card Configuration

The Mongo DB will be stored on the SD card. This will ensure that the OS partition does not fill up. Insert an SD Card formatted to FAT32 into the SD card slot.

mkdir /media/sdcard/db
mkdir /data
ln -s /media/sdcard/db /data/db

Mongo DB

We'll be installing version 2.6.12 since it's the last version to support 32-bit OS.

cd ~
wget https://fastdl.mongodb.org/linux/mongodb-linux-i686-2.6.12.tgz
mkdir ~/bin
cd ~/bin
tar -xvzf ../mongodb-linux-i686-2.6.12.tgz

Create a systemd script at /etc/systemd/system/mongod.service with the contents:

[Unit]
Description=Mongo is a scalable, document-oriented database.
After=syslog.target network.target

[Service]
ExecStart=/home/root/bin/mongodb-linux-i686-2.6.12/bin/mongod --journal

[Install]
WantedBy=multi-user.target

Enable the systemd script with:

systemctl enable mongod.service
