Jenkins

Jenkins is the leading open source automation server. Jenkins provides hundreds of plugins to support building, deploying and automating any project.

Installation

wget -q -O - https://jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

Configuration

Apache Proxy

For demo we DO NOT need use apache proxy, but for production installation we suggest to use apache or nginx
Configuration example:

<VirtualHost *:80>
	ServerAdmin webmaster@localhost
	ServerName ci.company.com
	ServerAlias ci
	ProxyRequests Off
	<Proxy *>
		Order deny,allow
		Allow from all
	</Proxy>
	ProxyPreserveHost on
	ProxyPass / http://localhost:8080/ nocanon
	AllowEncodedSlashes NoDecode
</VirtualHost>

• localhost:8080 is default Jenkins http address, and can be changed.

Ldap integration

Jenkins has built-in LDAP support, so we need to create LDAP users and enable LDAP in Jenkins:

Test LDAP

Manage Jenkins -> Configure Global Security --> LDAP
