In this tutorial, we're going to look at writing a simple installer for the wsdd server, and a samba setup script. When that's done, we package a self-extracting installer.
So, let's rock :)
Here I'm writing a Samba.conf setup script, made for configuring samba very simple. This is something a couple of people have asked for, since setting up samba seems difficult, so let's help them a bit shall we ?

This script takes two files from the wsdd.py and copies it into place. The wsdd.py into /usr/bin/, and the service file under /etc/systemd/system/, so it's pretty basic. I suggest you read through the script, and figure out what it does, it's pretty simple.
Next, go download wsdd from here https://github.com/christgau/wsdd
Next up, we need makeself, a shellscript for making the run file. Get it from https://github.com/megastep/makeself/blob/master/makeself.sh
So, make a new folder, call it something, eg wsdd_install. Copy the wsdd files into it, so you have wsdd.py and wsdd.service in there, and make a new file called setup.sh, and paste the above script into it.
Now, in the folder you're currently in, copy these files from the makeself project, so you have them in the folder next to your wsdd_install folder.
make-release.sh
makeself.lsm
makeself.1
makeself.sh
run-tests.sh
makeself-header.sh Now, we just need to run makeself.sh, and we do that like this, passing in our parameters
# Example command from makeself.sh
makeself.sh [args] archive_dir file_name label startup_script [script_args]
# example two
makeself.sh /full/path/to/source/folder/wsdd_install wsdd-installer.run "wsdd-installer" ./setup.shLet it run, and you should end up with a file called wsdd-installer.run. Now we simply run it with
./wsdd-installer.runWhen it runs, it will run the setup script, and do what's in there, and when it's done, clean up after itself. Pretty neat huh ?
Much Happy Installer Making ;)
