General procedure

Working directory structure

Here's an example directory structure for a package which replaces the apache default config file and sets up default php and html files in /var/www.

The control file in the DEBIAN sub-directory is where all the main configuration is done. The other three files in that sub-directory are scripts which execute on installation and removal of the package.

The rest of the directory structure outside the DEBIAN sub-directory define the directory structure which will be merged with the root of the filesystem when the package is installed.

Our packages at Organic Design are in /var/www/domains/packages and the source directory structures for them are in the sources subdirectory.

Building or updating a package

Next the source needs to be built into a .deb file, if this is being done for an existing package which is being updated, then don't forget to ensure that the version number in the control file is larger.

To turn the directory structure into a proper .deb package file, use: 

cd /var/www/domains/packages
dpkg -b source/<package-name> main/<package-name>.deb

Adding to a package repository

All the .deb package files must be added to the main repository on the server which is in /var/www/packages/main. Ensure that this repository is included in your /etc/apt/sources.list: 

echo "deb http://packages.organicdesign.co.nz main/" >> /etc/apt/sources.list


Whenever any of the packages in the repository change, the Packages.gz index file must be updated which can be done as follows. 

cd /var/www/domains/packages
dpkg-scanpackages main /dev/null | gzip > main/Packages.gz
