Megagear

How to use

git clone https://github.com/Filirom1/megagear.git
cd megagear

Simple usage

You will use bin/local-test, it's simplier than using bin/control directly.

First create a temporary directory

mkdir /tmp/megagear

NodeJs

Create a sample nodejs project

sudo npm i -g express
mkdir ~/express
cd ~/express
express
cd -

Download nodeJs v0.10.0, build the project and launch the web server.

export VERSION=0.10.0
rm -fr /tmp/megagear/instance0 && cp -r ~/express/ /tmp/megagear/repo &&  ./bin/local-test metadatas/nodejs.yml 

MongoDB

Download mongodb 2.4.5, start 3 instances and configure them as a replicaset

export VERSION=2.4.5
rm -fr /tmp/megagear/instance* &&  ./bin/local-test metadatas/mongodb.yml

Advanced usage

cd megagear
export PATH=`pwd`/bin:$PATH

NodeJs

Create dir structure

mkdir -p /tmp/instance/{tmp,data,build,admin,instance,repo}

Create a dummy nodejs app

sudo npm i -g express
cd /tmp/instance/repo
express

export VERSION="0.10.0"
export IP="127.0.0.1"
export PORT="1234"
export BUILD_DIR="/tmp/instance/build"
export ADMIN_DIR="/tmp/instance/admin"
export REPO_DIR="/tmp/instance/repo"
cd -
./bin/control admindo metadatas/nodejs.yml
./bin/control build metadatas/nodejs.yml
./bin/control start metadatas/nodejs.yml &
./bin/control status metadatas/nodejs.yml

MongoDB

Create dir structure

mkdir -p /tmp/mongodb/admin
mkdir -p /tmp/mongodb0/{tmp,data,instance}
mkdir -p /tmp/mongodb1/{tmp,data,instance}
mkdir -p /tmp/mongodb2/{tmp,data,instance}
