Error in cap deploy command

Hello to all!

I am getting following error while running cap deploy in terminal.

  * executing `deploy:update'

I also gave permissions to this application but still having same error.
Please help me to solve this error.

It cannot create /u/apps/mysite/releases/20121008150536 because the
permissions are wrong. Start at /u/apps/mysite and work down checking
the permissions

Ok.

Now I am getting following error:

And Cap deploy:setup works without any error. Check its result:

cap deploy:setup
  * executing `deploy:setup'
  * executing "mkdir -p ~/public_html/mysite
~/public_html/mysite/releases ~/public_html/mysite/shared
~/public_html/mysite/shared/system ~/public_html/mysite/shared/log

Try this in your deploy.rb

ssh_options[:forward_agent] = true

default_run_options[:pty] = true

Now it give result without error. Check its o/p below signature.

But my application is not started. I got following error when I open
domain(simak) in browser.
Is there any step to start rails app with capistrano which i was missing?

As you can see, your task deploy:restart is empty. You should restart your web server (like unicorn or passenger) in this task. You can define it like this

namespace :deploy do

desc “Restart Unicorn”

task :restart do

run "if [ -f #{unicorn_pid} ] && [ -e /proc/$(cat #{unicorn_pid}) ]; then kill -USR2 `cat #{unicorn_pid}`; else cd #{release_path} && bundle exec unicorn_rails -c #{unicorn_conf} -E #{rails_env} -D; fi"

end

end

Or just try to find this recipe in google :slight_smile:

I have used passenger and write namespace for that but still having
same result in browser.
"We're sorry, but something went wrong."

This page means error in rails. Look at your log/production.log.

this file has following error;
Mysql2::Error (Access denied for user 'root'@'localhost' (using password: NO)):

And when i run cap deploy:migrations the i got following error:

failed: "sh -c 'cd ~/public_html/mysite/releases/20121008162802 &&
rake RAILS_ENV=production db:migrate'" on simak

Now what i have to do?

I have also tried to login to mysql and it works. database.yml file
was also correct.
Now please tell me where's the problem.

Now cap deploy:migrations command works fine.
but still browser shows same message.

and production.log has mysql error.

Thanks to all for helping me. Problem Solved : ).
