# OSGeoLive



[OSGeoLive](https://live.osgeo.org) is a self-contained bootable DVD, USB thumb drive or Virtual Machine based on Lubuntu, that allows you to try a wide variety of open source geospatial software without installing anything. It is composed entirely of free software, allowing it to be freely distributed, duplicated and passed around.



## OSGeoLive installation scripts



The set of scripts in this repository will make a GIS Virtual Machine or bootable ISO from a base Lubuntu 22.04 (Jammy) system.



### Running installers



You can install individual applications in the base Lubuntu system by running `bin/install*.sh` scripts.

## How to add your project to OSGeoLive



Instructions for adding [new projects](https://wiki.osgeo.org/wiki/Live_GIS_Add_Project)



## Build the OSGeoLive DVD ISO image



### Build ISO



This section describes the new method for building OSGeoLive as described in [official ubuntu wiki](https://help.ubuntu.com/community/LiveCDCustomization). This section is self-contained and there is no need to perform any of the procedures described above.



All you need is a running Ubuntu/Xubuntu/Kubuntu/Lubuntu installation (even within a virtual machine as long as it has \~20GB free disk space). All needed to be done are the following steps under a "user" account:



* Bootstrap the host operating system. If you use the system to build more than once, then this must be done only for the first build



```

     host$ cd /tmp

     host$ wget https://github.com/OSGeo/OSGeoLive/raw/master/bin/bootstrap.sh

     host$ chmod a+x bootstrap.sh

     host$ sudo ./bootstrap.sh

```



This will install Git and the install scripts, and create a link to them from your home directory.



* Set the Version Number and Changes:

     * Update [VERSION.txt](https://github.com/OSGeo/OSGeoLive/blob/master/VERSION.txt) with the current version number.

     * Update [CHANGES.txt](https://github.com/OSGeo/OSGeoLive/blob/master/CHANGES.txt) with changes since the last release.

     * This list can be a summary of the [revision log](https://github.com/OSGeo/OSGeoLive/commits/master) between releases.

     * Commit the changes to Git through a Pull Request right before a release build.



* Execute the build script:

```

     host$ cd ~/gisvm/bin

     host$ sudo ./build_chroot.sh amd64 release master OSGeo 2>&1 | tee /var/log/osgeolive/chroot-build.log

```



* Compress the logs:

```

     host$ cd ~/livecdtmp

     host$ tar czf version-log.tar.gz -C /var/log osgeolive

```



* After the completion of the above script the new iso file is located in \~/livecdtmp along with the build logs. In case you wish to rerun the build process, do not remove or move the lubuntu official iso located in this folder to skip downloading it again.



* It is required to reboot your host machine after build is completed



* Once the ISO is complete copy it out to a server (a local server is fastest)

```

     scp ~/livecdtmp/osgeolive-mini-8.0.iso [email protected]:destination/path/

     scp ~/livecdtmp/osgeolive-mini-8.0-log.tar.gz [email protected]:destination/path/

```



* And/OR wget or scp the file to the upload.osgeo.org server (Note wget is much faster if you have a good webserver to host from)



### How to do development / debugging with the current build method



We have created a debug build process so that projects can now easily create their own iso, including parts of the OSGeoLive (eg only one project) in order to test if the installer scripts work well under this new build method. Here are the steps to debug/test your application:



#### One time steps



You will need to create a pure Lubuntu Virtual Machine setup:



* Download lubuntu-22.04-desktop-amd64.iso from [lubuntu web site](https://cdimage.ubuntu.com/lubuntu/releases/22.04.2/release/lubuntu-22.04.2-desktop-amd64.iso).



* Download and install VirtualBox.



* Create a fresh VM installation of Lubuntu. You will need to create a virtual disk drive with at least 25 GB of space and allocate 768MB of RAM to the VM. During installation set the username to "user" and hostname to "osgeolive". DO NOT install system updates during lubuntu installation or after the installation is done. At this moment we work with the default kernel included in lubuntu.



* After the VM is done, login as "user" and open a terminal.



* Bootstrap the VM:

```

     osgeolive$ cd /tmp

     osgeolive$ wget https://github.com/OSGeo/OSGeoLive/raw/master/bin/bootstrap.sh

     osgeolive$ chmod a+x bootstrap.sh

     osgeolive$ sudo ./bootstrap.sh

```



This will install Git, the install scripts, and create a link to them from your home directory.



#### Steps to create the build (repeat as much as needed)



* Make changes to your project's installation script and commit to Git.



* Update the git code:

```

     osgeolive$ cd ~/gisvm

     osgeolive$ git pull origin master

```



* Open file `inchroot.sh` with an editor and comment out all scripts you do not need for your test.

```

     osgeolive$ cd ~/gisvm/bin

     osgeolive$ vi inchroot.sh

```

* Always leave un-commented the following scripts: `setup.sh`, `install_services.sh`, `install_mysql.sh`, `install_java.sh`, `install_apache2.sh`, `install_tomcat.sh`, `install_desktop.sh` and `setdown.sh`. 



* Save your changes and execute the build:

```

     osgeolive$ cd ~/gisvm/bin

     osgeolive$ sudo ./build_chroot.sh amd64 2>&1 | tee /var/log/osgeolive/chroot-build.log

```



* After a while the iso will be created in \~livecdtmp/



* Do not delete the file \~/livecdtmp/lubuntu-22.04-desktop-amd64.iso as it will be needed for next build (saves time not to download again)



* Logs are created at /var/log/osgeolive/chroot-build.log



* Copy the iso and test



## Build the OSGeoLive DVD VM image



### Create the VM



The OSGeoLive Virtual Machine creation process is now exactly similar to a plain Lubuntu VM installation.

Use the mini iso file that was created from the previous chapter. 

Instructions can be found in the OSGeoLive [Documentation](https://live.osgeo.org/en/quickstart/virtualization_quickstart.html)



* Execute the VM build script:

```

     osgeolive$ cd ~/gisvm/bin

     osgeolive$ sudo ./install_vm_only.sh amd64 2>&1 | tee /var/log/osgeolive/vm-build.log

```



### Package the VM



From within the VM, fill empty space with zeros in order to be able to shrink the virtual disk files:

```

     osgeolive$ sudo ~/gisvm/bin/zerofill.sh

```

Shrink the virtual machine: 

```

     host$ VBoxManage modifymedium osgeolive.vdi --compact

```

Convert to vmdk format (more widely compatible):

```

     host$ VBoxManage clonehd osgeolive.vdi osgeolive-15.0-amd64.vmdk --format VMDK

```

OR with a recent version of QEMU

```

     host$ qemu-img convert -f vdi -o compat6 -O vmdk osgeolive.vdi osgeolive-15.0-amd64.vmdk

```

Zip the image up:

```

     host$ 7z a -mx=9 osgeolive-15.0-amd64.vmdk.7z osgeolive-15.0-amd64.vmdk

```

Create the md5sum checksums, so which can be used to confirm that the images have been downloaded correctly:

```

     host$ md5sum *.7z*

```



## Upload the Release



### Upload to sourceforge



As of 6.0 the official releases are hosted on sourceforge. To upload you need a sourceforge account and permissions to the osgeo-live project upload.

```

     host$ rsync -e ssh osgeolive-15.0-amd64.iso username,[email protected]:/home/pfs/project/o/os/osgeo-live/15.0/

```



### Upload to the OSGeo Server



```

     host$ scp -pr osgeolive-15.0-amd64.iso [email protected]:/osgeo/download/livedvd/

```

or

```

     host$ rsync --progress -e ssh osgeolive-15.0-amd64.iso [email protected]:/osgeo/download/livedvd/

```
