Nuxeo Demodata from GitHub fails

[olaf_]

The DemoData script

00-DownloadAndSetUpFullNuxeoDemo.sh

as can be found on GitHub: https://github.com/nuxeo/presales-vmdemo/wiki/Create-a-demo-from-one-of-Nuxeo-generic-demo-datasets is in more than one way troublesome.

1. It does not work on the VMs for 5.8 and 5.9.1 : nuxeoctl can not be found
2. Has a typo in the text: You should also probably expend the virtual hard drive to have enough space to get the demo dataset. --> expand (which is not entirely true so it seems)
3. A presumed role does not exists (see below)
4. rm command in script is invoked incorrectly (see below)
5. The script does not allow for symlinks to be more flexible regarding diskspace. A symlink in /etc/nuxeo for downloads is removed and replaced by a directory causing the root to fill to 100%

This was extensively tested on various platforms (hypervisors, OVFs, handmade VMs based on Debian Wheezy 64bit). Is it just me or is the script (no longer) functioning as intended?

No instance.clid found, the hotfixes will not be installed on the server. Altough not mandatory, it is highly recommended. The instance.clid is looked for in the parent of the nuxeo_demo folder. In your case in:

instance.clid files can be generated by registering another instance and getting the instance.clid file.

Hi,

[olaf_]

Thanks Fred. You were right. I was indeed user root when I executed the script. However the other points seem still to be valid. I did some further investigation on the OVF-VM download of 5.9.1. The reason the script does not execute properly there (including when being user nuxeo) is that the script assumes it can unzip Tomcat and it cannot because the unzip package is not installed. If installed beforehand the script executes properly.

I think the install script can be improved by:

1. fixing the rm error which is still in the script
2. checking for diskspace before downloading: parse: df
3. allow for symlinking if space is limited in /etc/ (which in itself is not the most desirable place to store downloads imho)
4. get the working directory and check if it is the correct one: http://stackoverflow.com/questions/59895/can-a-bash-script-tell-what-directory-its-stored-in
5. get the current user and check. Then either exit with error or sudo to nuxeo: http://codeblog.vurdalakov.net/2010/12/how-to-get-current-user-name-in-bash.html and http://my-wd-local.wikidot.com/othertip:switching-users-in-a-bash-script

Links are provided for inspiration to make the script more robust. Maybe also some preliminary testing or even executing of the postgreSQL commands can also be implemented? Thank you for providing this demo data. Makes life much easier when testing! List item
