Cap deploy problem

Rails Deployment

Can anybody tell me what’s happening here?

I can do this, with the expected results:

ssh -l somename dir2.com cd /var/www/dir1/dir2/current && ls -l

But then I do something similar via Capistrano I get an error at the
end…

  • executing task symlink
  • executing “ln -nfs /var/www/dir1/dir2/releases/20070302122224
    /var/www/dir1/dir2/current”
    servers: [“dir2.com”]
    [dir2.com] executing command

  • executing task restart

    command finished
  • executing task start_backgroundrb
  • executing “RAILS_ENV=production nohup cd /var/www/dir1/dir2/current
    && script/backgroundrb start”
    servers: [“dir2.com”]
    [dir2.com] executing command
    ** [out :: dir2.com] nohup:
    ** [out :: dir2.com] appending output to nohup.out' ** [out :: dir2.com] nohup: ** [out :: dir2.com] cannot run command cd’
    ** [out :: dir2.com] : No such file or directory

I can give the same command from an ssh login shell and it works as
expected.

Clues for the clueless?

This is the command that is failing:

RAILS_ENV=production nohup cd /var/www/dir1/dir2/current &&
script/backgroundrb start

I believe this will fail if you run it directly as well.

Try changing it to this:
export RAILS_ENV=production && cd /var/www/dir1/dir2/current && nohup
script/backgroundrb start

(You may also need to add an ‘&’ to the end.)

Thanks! That worked great.

That isn’t necessary with the current version of backgroundrb.

Again, thank you for your help.
