I have a command service app start-demo requires me to type sudo service app start-demo in the command line.

I used sudo(service app start-demo) and sudo(sudo service app start-demo) but I still get

Warning: sudo() encountered an error (return code 1) while executing 'sudo service app start-demo'

I have no problem executing that as a command line in a terminal.

I am not sure if SADeprecationWarning: counts as a failure to fabric?

Thanks.

either sudo command will fail.

  • Does your `sudo` configuration require you to type a password at the terminal? – sarnold Jul 05 '12 at 23:21
  • Did you put the command in quotes? It should be `sudo("service app start-demo")`. – mayhewr Jul 06 '12 at 00:02
  • @sarnold It doesn't. When I do `sudo` on terminal, it won't ask. I ran as fab it didn't ask either. – user423455 Jul 06 '12 at 01:48
  • @mayhewr Oh yes. MY bad. I do. Otherwise, it would complain as syntactic error. :)) – user423455 Jul 06 '12 at 01:49
  • SADeprecationWarning should not be the problem. Even if it were, the service would still start (since it certainly knows it's just a warning), but fabric could report it as a failure. If the service doesn't start, the problem must be somewhere else. If you're still having the problem, post a more complete traceback/output. – mayhewr Jul 06 '12 at 17:06
  • @mayhewr Thanks. I've updated with a complete log. Is that what you need? If not, please let me know. – user423455 Jul 06 '12 at 17:13
  • @user423455: so you have configured whatever you want to run in `/etc/sudoers` as `NOPASSWD`? Because the cached password you gave in your own shell for a test run of the command with `sudo` *may* not actually be useful to the command you're trying to run here. – 0xC0000022L Jul 06 '12 at 17:15
  • @0xC0000022L Hi there. Thanks. Shouldn't `fab` uses the current user as the sudo account, and asks for access? Or is that not so? I believe I did. I am posting the file in just a bit. – user423455 Jul 06 '12 at 17:26

This is prolly related to this mention in the faq, but also if the command doesn't return 0 (unix standard for all good) it'll fail-fast unless you tell it to warn only.

  • Thansk! That's a very good finding :) Now.. one more thing... fab doesn't return. It just waits there. Why is that? – user423455 Jul 06 '12 at 18:10
  • Most likely due to some nohup or backgrounding stuff, also [mentioned in the FAQ](http://docs.fabfile.org/en/1.4.2/faq.html#why-can-t-i-run-programs-in-the-background-with-it-makes-fabric-hang) – Morgan Jul 09 '12 at 15:18
