Running Sync Gateway on RPi 2
#Running Sync Gateway on RPi 2
Follow these steps to Build and Run Sync Gateway on Raspberry Pi 2.
##Why is this useful
Couchbase mobile can support tree topologies, where Sync Gateway instances are deployed to distributed geographical locations to provide local sync points.
These remote Sync Gateway instances can do local processing of documents and send aggregate information to a central Sync Gateway in a data centre.
In many cases deploying a full Sync Gateway cluster at remote locations will not be practical or cost effective, e.g. in retail stores or hostile (to computers) environments.
A low power embedded system may be more suited to these environments.
Embedded Sync Gateway may also be useful for mini-hacks and hands on demonstrations.
##Setup RPi 2 Follow standard instructions to install Raspbian operating system
##Installing Go Lang tools on RPi
wget http://dave.cheney.net/paste/go1.4.2.linux-arm~multiarch-armv7-1.tar.gz
sudo tar -C /usr/local -xzf go1.4.2.linux-arm~multiarch-armv7-1.tar.gz
##Add Go Lang tools to PATH
export PATH=$PATH:/usr/local/go/bin
##Install Git client
sudo apt-get install git sudo apt-get install bc
##Download Sync Gateway source
git clone https://github.com/couchbase/sync_gateway.git
git submodule update --init --recursive
cd sync_gateway
./build.sh
##Run Sync Gateway
bin/sync_gateway examples/admin_party.json
##Test Sync Gateway
curl -X GET http://localhost:4985/db/
#Known Issues
Embedded Sync Gateway is using the walrus embedded DB, this DB is designed for local development and testing and does not provide write ahead logs for durability e.t.c
Sync Gateway could use an Embedded ForestDB instance for durable and scalable storage/indexing.
