services didnt start

A couple of questions:

What version of SchoolTool are you using? Is it a new installation or did you change some configuration to an old one?

Could you please attach these log files:

/var/log/schooltool/error.log
/var/log/schooltool/celery_report.log
/var/log/schooltool/paste.log

Thanks.

I didn´t any changes, how do I see the school tool version?

Your error.log file doesn't show anything wrong. Could you attach the other two files?

To find SchoolTool's version run this command in a terminal (and paste the output here):

$ apt-cache policy schooltool

the others files have 0 kb.

root@cloud-server-06-ubuntu:~# apt-cache policy schooltool
Segmentation fault

how could I reinstalll the school tool with default configuration?

Try (alternative to get SchoolTool's version):

$ dpkg -s schooltool

Are you just testing/trying SchoolTool or is this a "production" server? What version of Ubuntu are you running? Out of curiosity, how much RAM do you have in this server?

I am testing school tool.

I may be wrong, but in my opinion, the issue is that your server has not enough RAM, and more importantly no swap space (the segmentation fault you reported is also very suspicious). I've seen processes dying with memory errors in this scenario. I recommend you to either upgrade your RAM or test using another approach (like a local virtual machine).

To uninstall SchoolTool you can:

$ sudo apt-get purge schooltool

Some directories will not be removed (because they contain data), but if you don't have important data in the instance and you want to start completely clean again, you can remove them manually:

$ sudo rm -rf /var/lib/schooltool/
$ sudo rm -rf /var/log/schooltool/
$ sudo rm -rf /var/run/schooltool/
$ sudo rm -rf /etc/schooltool

Then you can install again:

$ sudo apt-get install schooltool
