Building Your Jsbin Service

Log — Tags: jsbin, node — Posted by Starck on November 2, 2013

Install node and npm
Install jsbin

npm install jsbin or npm install -g jsbin

if have node not found problem, link it to `/usr/bin

ln -s /usr/local/bin/node /usr/bin/node
Clone jsbin project form github

git clone [email protected]:remy/jsbin.git
Jsbin configuration settings

Go to jsbin project folder

cp config.default.json config.local.json and modify it. mkdir tmp; mkdir tmp/pids and chmod 777 tmp/pids
Install init.d script

vim /etc/init.d/jsbin and chmod +x /etc/init.d/jsbin

Change {userid} to your user id.
