Hudson是个非常强大持续集成工具，配合svn，maven，sonar，redmine工具就更加完美了。大家要了解Hudson的介绍可以看这篇文章，我在这里就不详细介绍了。此外额外说下，由于Hudson被oracle收购后以前开发Hudson团队转移到了jekins。大家有兴趣可以google下。

Build Hudson Continuous Integration Environment

General steps：

1. Install the jdk environment

You can dowload the jdk in ”deb” suffix (http://www.oracle.com/technetwork/java/javase/downloads/index.html). And using a command "dpkg -i deb file path" to install it.
Then you should set the environment. You can edit "/etc/profile" file, add followings to it`s tail :

JAVA_HOME=/home/liujicheng/java/jdk1.6.0_12
export JRE_HOME=/home/liujicheng/java/jdk1.6.0_12/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

2. Install hudson

On ubuntu, we always install a software with a file with a sufix "deb". You can download hudson with "deb" suffix (http://hudson-ci.org/) . And install it.

3. Install Vncserver

You can use command : "apt-get install tightvncserver".

4. Install subversion

You can use command : "apt-get install subversion".

5. Install svn

You can use command : "apt-get install svnkit".

6. Install smtp

You can use command : "apt-get install sendemail".

7. Configure hudson on hudson web page

The default port is 8080. You can reach to the page by visit "http://:<8080>", if you use the default port.

7.1 Plugins may needed to be installed.

SCP plugin, Gant Plugin, Hudson Emma plugin, Maven 2 job type plugin, Plot plugin, Hudson Dependency Viewer Plugin, Hudson Subversion Plug-in, Performance plugin, ChuckNorris Plugin, Hudson :: Maven 3 :: SNAPSHOT, MonitorJFreeChart Plugin, Maven 3 Build Plugin, Hudson CVS Plug-in, Maven Info Plugin, Measurement Plots, Sonar Plugin, Hudson Xvnc plugin, Hudson Mercurial plugin, Hudson disk-usage plugin, FTP publisher plugin, Redmine Plugin.

7.2 Configures hudson

Example:

8. Build a job

8.1 Build a new job

Example:

8.2 Copy a job

If you want to build a job which has same configuration with existing job
Example:

8.3 Configure a job

9. Commands of hudson

Start/stop/restart hudson : /etc/init.d/hudson start start/stop/restart

10. Install sonar

Download zip file from official website.
Unzip the file to any directory you want.
Go to the directory named "bin" of sonar. Then you will see the version of system you should choose.
Go to right directory and execute command:"sudo ./sonar.sh start".
Sonar and other files should can be executed. You can use command："sudo chmod 770 file_name".
You can visit sonar by the address like: http://: . The default account: admin/admin.

Possible problem and it`s solution

1. Build JDK environment on ubuntu.

After jdk is installed, you need to set the jdk enironment. You can set a common jdk environment for every user through configuring "/etc/profile". In linux, the global profile always located in "/etc/"

2. Build Hudson Continuous Integration environment

3. Build a job

3.1 Lack vncserver software

Problem: FATAL: Cannot run program "vncserver" (in directory "/var/lib/hudson/jobs/csc_proto/workspace"): java.io.IOException: error=2, No such file or directory java.io.IOException: Cannot run program "vncserver" (in directory "/var/lib/hudson/jobs/csc_proto/workspace"): java.io.IOException: error=2, No such file or directory at java.lang.ProcessBuilder.start(ProcessBuilder?.java:488) at hudson.Proc$LocalProc.(Proc.java:187) at hudson.Proc$LocalProc.(Proc.java:157) at hudson.Launcher$LocalLauncher.launch(Launcher.java:649) at hudson.Launcher$ProcStarter.start(Launcher.java:266) at hudson.plugins.xvnc.Xvnc.doSetUp(Xvnc.java:94) at hudson.plugins.xvnc.Xvnc.setUp(Xvnc.java:80) at hudson.model.Build$RunnerImpl.doRun(Build.java:129) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild?.java:434) at hudson.model.Run.run(Run.java:1390) at hudson.model.FreeStyleBuild.run(FreeStyleBuild?.java:40) at hudson.model.ResourceController.execute(ResourceController?.java:82) at hudson.model.Executor.run(Executor.java:137) Caused by: java.io.IOException: java.io.IOException: error=2, No such file or directory at java.lang.UNIXProcess.(UNIXProcess.java:164) at java.lang.ProcessImpl.start(ProcessImpl?.java:81) at java.lang.ProcessBuilder.start(ProcessBuilder?.java:470) ... 12 more

Solution: Install a vncserver on the server. You can use command "apt-cache search vncserver" to find the vncserver software name, then use the command "apt-get install vncserver software name"

3.2 Having not set vncserver`s password

Problem: Another problem block the build process. The problem and solution are here：
