Jenkins, previously known as Hudson, is an open source continuous integration server. Built with Java, it provides over 400 plugins to support building and testing virtually any project. It supports SCM tools including CVS, Subversion, Git, Mercurial, Perforce and Clearcase, and can execute Apache Ant and Apache Maven based projects as well as arbitrary shell scripts and Windows batch commands. It also can monitor executions of remote tasks.
Please, take a look to the Quick Start Guide to know the basic use of this Stack.
How to start/stop the servers?
The Stacks include a graphical tool to manage the servers easily. You can find the "manager-windows.exe", "manager-osx" or "manager-linux" tool in your installation directory. Using this tool, you can Start, Stop or Restart the servers and check the log files. You can click on the icon to start it.
On Windows: You can also start the Manager tool from shortcuts: Start -> Program Files -> BitNami Stack -> Manager tool
If you prefer, you can use the "ctlscript.sh" utility from the command line. This script is in the installation directory.
On OS X: You can start the Manager tool from the installation directory or you can use the "ctlscript.sh" utility from a Terminal.
host:~ user$ cd /Applications/application-version host:~ user$ ./ctlscript.sh start
$ cd ~/applicaton-version $ ./ctlscript.sh start
Where is JENKINS_HOME variable pointing to?
We define JENKINS_HOME in your installation directory in the apache-tomcat/conf/Catalina/localhost/jenkins.xml file. By default it is pointing to apps/jenkins/jenkins_home.
How to upgrade Jenkins?
If you want to upgrade Jenkins keeping your data, you just need to download the latest jenkins.war file, copy it in your apache-tomcat/webapps directory and restart Tomcat. Of course it is always recommended to create a backup of the previous jenkins.war file. You may want to revert to the previous version if you issues when upgrading.
Upgrading only Jenkins
$ cd <installation_directory>
## Stop the server
On Windows you can stop the servers from the Start Menu entry or using the graphical tool that you can find in your installation directory. Using the file explorer go to where you installed the BitNami Jenkins Stack. Copy the jenkins.war file from the apache-tomcat/webapps directory to apps/jenkins. Download the latest jenkins.war file and copy it in apache-tomcat/webapps. Now just start the server from the Start Menu or using the graphical tool.
Upgrading all the components
Alternatively to the process above, you can download a new BitNami Jenkins Stack. You can install it to a different location (remember to stop the previous install so there are no port conflicts) and point it to your previous JENKINS_HOME path by editing the file apache-tomcat/conf/Catalina/localhost/jenkins.xml.
If you are using a BitNami virtual appliance or AMI you can start a new image with the latest jenkins version and move the content of /opt/bitnami/apps/jenkins/jenkins_home in your current installation to the new installation. Then restart the server.
How to enable SSL in Jenkins?
You can configure Apache Tomcat to enable SSL connections for accessing to the application using the HTTPS protocol. It is necessary to specify the Apache SSL certificate. If you do not have the cert you can create following these steps in the section below.
Check that you have the certificate file at "/installdir/apache-tomcat/conf/ssl/tomcat.cert.pem" and the certificate key file at "/installdir/apache-tomcat/conf/ssl/tomcat.key.pem".
To enable SSL you should uncomment the following line in the /installdir/apache-tomcat/conf/server.xml file:
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" disableUploadTimeout="true" acceptCount="100" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="conf/myKeystore" keystorePass="mysqlnetwork" SSLCertificateFile="installdir/apache-tomcat/conf/ssl/tomcat.cert.pem" SSLCertificateKeyFile="installdir/apache-tomcat/conf/ssl/tomcat.key.pem"/>
Then restart the Apache server and try to access at "https://localhost:8443".
How to create a SSL certificate for Jenkins?
You can find a detailed guide in the official Apache Tomcat documentation at http://tomcat.apache.org/tomcat-6.0-doc/ssl-howto.html
