1 **[[Jenkins>>http://jenkins-ci.org/]]** is an "extensible continuous integration server". It monitors repeated executions of jobs, such as building software projects, and can be used to build WebObjects applications and frameworks. Jenkins is an open source project and can be used at no cost. It is hosted on [[Github.com>>https://github.com/jenkinsci]].
2
3 An introductory presentation on building WebObjects projects with Hudson (the predecessor to Jenkins) was given by Mike Schrag at WOWODC-West in 2009, and the video can be [[purchased from wocommunity.org>>http://www.wocommunity.org/apps/WebObjects/WOCommunity.woa/wa/recordings]].

5 === Upgrading from Hudson ===
6
7 Switching from Hudson to Jenkins is straight-forward since Hudson was the foundation that Jenkins was forked from. jenkins-ci.org has a [[wiki entry>>https://wiki.jenkins-ci.org/display/JENKINS/Upgrading+from+Hudson+to+Jenkins]] to help with the change.
8
9 === Stand-Alone Mac OS X Setup ===
10
11 1. Download the Jenkins Binary Installer from the [[Jenkins Website>>http://jenkins-ci.org/]].
12 The direct link to get the latest installer is: [[http://mirrors.jenkins-ci.org/osx/latest]]. This will download a standard OS X Installer Package named ##jenkins-n.nnn.pkg##.
13 1. Run the installer
14 [[image:JenkinsInstaller.png]]
15 1. Restart your computer
16 This is required because the current version of Jenkins does not create the its directory until it launches after you restart you computer.
17 1. Point your browser to: [[http://localhost:8080/]]
18 1. Start setting up jobs (Instructions from WOWODC2011 Coming Soon)
19
20 === Stand-Alone CentOS/RedHat/Amazon Linux ===
21
22 The easiest way to install Jenkins on a Fedora/RedHat/CentOS/Amazon Linux is by using [[Yum>>http://en.wikipedia.org/wiki/Yellow_dog_Updater,_Modified]]. The Jenkins project have a Yum repository and [[complete instructions>>https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+RedHat+distributions]] on how to add the repository + install Jenkins the first time. You can also manually install Jenkins from a RPM available on jenkins-ci.org.
23
24 Please note that on CentOS 5.x (I don't know for CentOS), the list of root certificates is old, and you will get error when trying to clone a Git repository coming from GitHub. To update the list of root certificates, do:
25
26 {{code}}
27
28 sudo cp /etc/pki/tls/certs/ca-bundle.crt /etc/pki/tls/certs/ca-bundle.crt.original
29 sudo curl http://curl.haxx.se/ca/cacert.pem \-o /etc/pki/tls/certs/ca-bundle.crt
30
31 {{/code}}
32
33 === Using SSL ===
34
35 Setting up SSL for Jenkins is surprisingly easy. The following is originally from the [[SSL Setup Options>>http://jenkins.361315.n4.nabble.com/SSL-Setup-Options-td954261.html]] page on nabble.com:
36
37 1. Create a selfsigned test SSL certificate. 
38 keytool genkey keyalg RSA alias selfsigned keystore keystore.jks -storepass ToPSecRet321 dname "cn=localhost"
39 1. Launch Jenkins.
40
41 {{noformat}}
42 java -jar jenkins.war --httpPort=-1 --httpsPort=8080 --httpsKeyStore=keystore.jks --httpsKeyStorePassword=ToPSecRet321
43 {{/noformat}}
44
45 1. Launch browser 
46 Open "https:~/~/localhost:8080" in browser. You might get a browser warning, because the certificate is not signed by a known certificate authority. Communication is SSL-encrypted nevertheless.
47
48 {{note title="Please Note"}}
49 The port has changed from the original instructions. That was required on Mac OS X because of permissions. Also, it's worth noting that the keytool asks for a second password for the private key of the ssl certificate. We are using the same password as the keystore password and everything works. It is unclear if that makes a difference.

52 === Servlet Container Installation on Mac OS X (10.5, 10.6) ===
53
54 1. Install Tomcat from [[http://www.macports.org]] with the command
55
56 {{noformat}}
57
58 sudo /opt/local/bin/port install tomcat6
59
60 {{/noformat}}
61
62 1. Create an administrative user in ##/opt/local/share/java/tomcat6/conf/tomcat-users.xml##.
63
64 {{code value="xml"}}
65
66 <?xml version='1.0' encoding='utf-8'?>
67 <tomcat-users>
68 <role rolename="manager"/>
69 <role rolename="admin"/>
70 <user username="tomcat" password="tomcat" roles="admin,manager"/>
71 </tomcat-users>
72
73 {{/code}}
74
75 {{panel bgColor="#F7D6C1"}}
76
77 Don't forget to change the username and password after you have finished checking out the build server and start using it in production.
78
79 {{/panel}}
80
81 1. Start Tomcat.
82
83 {{noformat}}
84
85 sudo launchctl load -w /Library/LaunchDaemons/org.macports.tomcat6.plist
86
87 {{/noformat}}
88
89 1. [[Download Jenkins>>http://mirrors.jenkins-ci.org/war/latest/jenkins.war]], saving ##jenkins.war## somewhere for later.
90 1. Create a folder for Jenkins to work in: ##/opt/local/var/db/jenkins##
91 1. Change ownership of that folder: ##chown www:_www /opt/local/var/db/jenkins##
92 1. Add the following to ##/opt/local/share/java/tomcat6/conf/setenv.local##:
93
94 {{noformat}}
95
96 export JENKINS_HOME=/opt/local/var/db/jenkins
97 export JAVA_OPTS=-Djava.awt.headless=true
98
99 {{/noformat}}
100
101 1. Install Jenkins in Tomcat: go to [[http://localhost:8080]], login with the user and password that you have created in ##tomcat-users.xml##, and upload ##jenkins.war## to the Tomcat server.
102 1. Goto [[http://localhost:8080/jenkins]] and you can start configuring your Jenkins build server.

130 1. Add the following to ##/Library/Tomcat/bin/setenv.sh##:
131
132 {{code}}
133
134 export JENKINS_HOME=/Library/Jenkins
135 export JAVA_OPTS=-Djava.awt.headless=true
136
137 {{/code}}
138
139 1. Make sure that you are using UTF-8 in the Connector, by adding ##URIEncoding="UTF-8"## to the Connector in ##/Library/tomcat/conf/server.xml## as shown here:
140
141 {{code value="xml"}}
142
143 <Connector port="8080" protocol="HTTP/1.1"
144 connectionTimeout="20000"
145 redirectPort="8443" URIEncoding="UTF-8"/>

154 * Check out [[Installing and Configuring Jenkins Build Server^setupWorkspace.sh]]
155
156 == Jenkins plugins ==
157
158 After Jenkins is installed and started, you will need to install at the very minimum two plugins: [[Multiple SCMs>>https://wiki.jenkins-ci.org/display/JENKINS/Multiple+SCMs+Plugin]] and [[Git>>https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin]]. They are required if you need to build projects by using the WOJenkins templates. If your projects are under another SCM like Subversion or CVS, you also need to install Jenkins for it.
