| = Setting up a Jenkins Build Server = | ||
|
|
||
| **Assumption:** You know how to make a working build environment and want to | ||
| deploy it under Jenkins for continuous integration testing now. | ||
|
|
||
| These notes are terse, I will expand on them later as the need arises. The | ||
| procedure is: | ||
|
|
||
| - Install Jenkins and get it configured according to your own preferences | ||
| - Make sure you have the git, github, junit etc plugins installed. A complete | ||
| list of the plugins I have installed follows (note that you almost certainly | ||
| don't need evey plugin listed here): | ||
| - External Monitor Job Type Plugin | ||
| - LDAP Plugin | ||
| - pam-auth | ||
| - javadoc | ||
| - ant | ||
| - Jenkins Subversion Plug-in | ||
| - Git Plugin | ||
| - Maven 2 Project Plugin | ||
| - Jenkins SLOCCount Plug-in | ||
| - Jenkins Sounds plugin | ||
| - Jenkins Translation Assistance plugin | ||
| - ruby-runtime | ||
| - Jenkins CVS Plug-in | ||
| - Coverage/Complexity Scatter Plot PlugIn | ||
| - Status Monitor Plugin | ||
| - Git Parameter Plug-In | ||
| - github-api | ||
| - GitHub plugin | ||
| - Jenkins Violations plugin | ||
| - git-notes Plugin | ||
| - Twitter plugin | ||
| - Jenkins Cobertura Plugin | ||
| - Jenkins Gravatar plugin | ||
| - Jenkins SSH Slaves plugin | ||
| - Create a Job called 'QGIS' | ||
| - Use the following options for your job: | ||
| - Job Name: QGIS | ||
| - Job Type: Build a free-style software project | ||
| - Tick enable project based security (you need to elsewhere configure your | ||
| Jenkins security to per project settings) | ||
| - Allow Anonymous user Read and Discover access | ||
| - Set the github project to https://github.com/qgis/Quantum-GIS/ | ||
| - Set source code management to Git | ||
| - Set repository url to git://github.com/qgis/Quantum-GIS.git | ||
| - In advanced repository url settings set refspec to : | ||
|
|
||
| ``` | ||
| +refs/heads/master:refs/remotes/origin/master | ||
| ``` | ||
|
|
||
| - Set branch to build to master | ||
| - Repository Browser: Auto | ||
| - Build triggers: set to Poll SCM and set schedule to ``* * * * *`` (polls every minute) | ||
| - Build - Execute shell and set shell script to: | ||
|
|
||
| ``` | ||
| cd build | ||
| cmake .. | ||
| xvfb-run --auto-servernum --server-num=1 \ | ||
| --server-args="-screen 0 1024x768x24" \ | ||
| make Experimental || true | ||
| if [ -f Testing/TAG ] ; then | ||
| xsltproc ../tests/ctest2junix.xsl \ | ||
| Testing/`head -n 1 < Testing/TAG`/Test.xml > \ | ||
| CTestResults.xml | ||
| fi | ||
| ``` | ||
|
|
||
| - Add Junit post build action and set 'Publish Junit test result report' to: | ||
| ``build/CTestResults.xml`` | ||
| - Email notification: Send separate e-mails to individuals who broke the build | ||
| - Jenkins sounds - set up sounds for Failure, Success and Unstable. | ||
| - Save | ||
| - | ||
|
|
||
| Now open the Job dash board and push something to QGIS and wait a minute to | ||
| validate automated builds work. | ||
|
|
||
| **Note:** You will need to log in to the Jenkins user account and go to | ||
| /var/lib/jenkins/jobs/QGIS/workspace, then make a ``build`` directory and run | ||
| the initial cmake setup and then do test build. This process is the same as | ||
| described elsewhere in this doc. | ||
|
|
||
| I based some of the set up from this nice blog article here: | ||
|

| = Setting up the WCS test server on GNU/Linux = | ||
|
|
||
| **Requires:** Ubuntu / Debian derived distro | ||
|
|
||
| These notes are for Ubuntu - other versions and Debian derived distros may | ||
| require slight variations in package names. | ||
|
|
||
| == Preparation == | ||
|
|
||
| Note the git repo below will change to the default QGIS repo once this work | ||
| is integrated into master. | ||
|
|
||
| git remote add blazek git://github.com/blazek/Quantum-GIS.git | ||
| git fetch blazek | ||
| git branch --track wcs2 blazek/wcs2 | ||
| git checkout wcs2 | ||
| cd /var/www/ | ||
| sudo mkdir wcs | ||
| sudo chown timlinux wcs | ||
| cd wcs/ | ||
| mkdir cgi-bin | ||
| cd cgi-bin/ | ||
|
|
||
| == Setup mapserver == | ||
|
|
||
| ```sudo apt-get install cgi-mapserver``` | ||
|
|
||
| Set the contents of cgi-bin/wcstest-1.9.0 to: | ||
|
|
||
| ``` | ||
| #! /bin/sh | ||
| MS_MAPFILE=/var/www/wcs/testdata/qgis-1.9.0/raster/wcs.map | ||
| export MS_MAPFILE | ||
| /usr/lib/cgi-bin/mapserv | ||
| ``` | ||
|
|
||
| Then do: | ||
|
|
||
| ``` | ||
| chmod +x cgi-bin/wcstest-1.9.0 | ||
| mkdir -p /var/www/wcs/testdata/qgis-1.9.0/raster/ | ||
| cd /var/www/wcs/testdata/qgis-1.9.0/raster/ | ||
| cp -r /home/timlinux/Quantum-GIS/tests/testdata/raster/* . | ||
| ``` | ||
|
|
||
| Edit wcs.map and set the shapepath to this: | ||
|
|
||
| ``` | ||
| SHAPEPATH "/var/www/wcs/testdata/qgis-1.9.0/raster" | ||
| ``` | ||
|
|
||
| Then create /var/www/wcs/7-wcs.qgis.org.conf setting the contents to this: | ||
|
|
||
| ``` | ||
| <VirtualHost *:80> | ||
| ServerName wcs.qgis.org | ||
| ServerAdmin tim@linfiniti.com | ||
|
|
||
| LogLevel warn | ||
| LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" \"%{forensic-id}n\"" combined | ||

| ErrorLog /var/log/apache2/wcs_qgis.org/error.log | ||
|
|
||
| DocumentRoot /var/www/wcs/html | ||
|
|
||
| ScriptAlias /cgi-bin/ /var/www/wcs/cgi-bin/ | ||

|
|
||
| RewriteEngine on | ||
| RewriteRule /1.9.0/wcs /cgi-bin/wcstest-1.9.0 [PT] | ||
|
|
||
| </VirtualHost> | ||
| ``` | ||
|
|
||
| == Create a home page == | ||
|
|
||
| ``` | ||
| mkdir html | ||
| vim html/index.html | ||
| ``` | ||
|
|
||
| Set the contents to: | ||
|
|
||
| ``` | ||
| This is the test platform for QGIS' wcs client. You can use these services | ||
| from QGIS directly (to try out WCS for example) by pointing your QGIS to: | ||
| http://wcs.qgis.org/1.9.0/wcs | ||
| ``` | ||
|
|
||
|
|
||
| == Now deploy it == | ||
|
|
||
| ``` | ||
| sudo mkdir /var/log/apache2/wcs_qgis.org | ||
| sudo chown www-data /var/log/apache2/wcs_qgis.org | ||
| cd /etc/apache2/sites-available/ | ||
| sudo ln -s /var/www/wcs/7-wcs.qgis.org.conf . | ||
| cd /var/www/wcs/ | ||
| sudo a2ensite 7-wcs.qgis.org.conf | ||
| sudo /etc/init.d/apache2 reload | ||
| ``` | ||
|
|
||
| == Debugging == | ||
|
|
||
| ``` | ||
| sudo tail -f /var/log/apache2/wcs_qgis.org/error.log | ||
| ``` |
