Setting up Jenkins 1 on Linux

The instructions below are for a Red Hat/CentOS server but can be easily adapted for other Linux distributions.

Installing Jenkins

Follow the instructions from https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Red+Hat+distributions

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
sudo yum install jenkins

sudo service jenkins start

A jenkins user has been created, its home directory is /var/lib/jenkins

Configuring Jenkins

Installing JDK 8

Through Jenkins administration, add a JDK 8 automatic installer.

Installing Maven

Through Jenkins administration, add a Maven automatic installer from Apache’s site.

Installing NodeJS

You could install NodeJS globally but it’s very likely that you may want to have different versions of NodeJS for different projects.

We suggest 2 alternatives below, choose the one you prefer.

Jenkins NodeJS plugin

Install Jenkins NodeJS plugin.

Through Jenkins administration, add a NodeJS installation:

• Automatic installer from nodejs.org, use the latest LTS (Long Term Support) version
• Global npm packages to install: bower gulp

Local NodeJS installation

Install NodeJS locally using the script below and then update the Jenkins PATH to use it.

# specify which version we want
export NODE_VERSION=4.3.1

# download
cd /tmp
wget http://nodejs.org/dist/v$NODE_VERSION/node-v4.3.1.tar.gz
tar xvfz node-v$NODE_VERSION.tar.gz

# build it and install it only locally
cd node-v$NODE_VERSION
./configure --prefix=/var/lib/jenkins/node-v$NODE_VERSION && make && make install

# Check versions of node and  npm
export PATH=/var/lib/jenkins/node-v$NODE_VERSION/bin:$PATH
node --version
# v4.3.1
npm --version
# 3.7.5

# install tools
npm install -g bower gulp
bower --version
# 1.7.7
gulp --version
# 3.9.1

Make sure you update the Jenkins PATH.
