Capistrano Deploy -- Net::SSH::AuthenticationFailed -- AWS EC2

Question

Why am I getting authenicationFailed when I try to run deploy setup? I am using the ssh as my password. Do I need to change anything in the database.yml or deploy.rb. They are listed below.

$ cap deploy:setup
  * executing `deploy:setup'
  * executing "sudo -p 'sudo password: ' mkdir -p /var/www/apps/sample_app /var/www/apps/sample_app
 /releases /var/www/apps/sample_app/shared /var/www/apps/sample_app/shared/system /var/www     
/apps/sample_app/shared/log /var/www/apps/sample_app/shared/pids"
    servers: ["ec2-20-21-42-51.compute-1.amazonaws.com"]
Password: 
connection failed for: ec2-20-21-42-51.compute-1.amazonaws.com 
(Net::SSH::AuthenticationFailed: ubuntu)

deploy.rb

# The name of your app
set :application, "sample_app"

# The directory on the EC2 node that will be deployed to
set :deploy_to, "/var/www/apps/#{application}"

set :keep_releases, 3

# deploy with git
set :scm, :git
set :repository,  "[email protected]:username/sample_app.git"
set :git_shallow_clone, 1
set :branch, "master"
set :use_sudo, true

set :user, "ubuntu"
ssh_options[:forward_agent] = true
default_run_options[:pty] = true

# The address of the remote host on EC2 (the Public DNS address)
set :location, "ec2-20-21-42-51.compute-1.amazonaws.com"

# setup some Capistrano roles
role :app, location
role :web, location
role :db,  location, :primary => true

after 'deploy:update_code', 'deploy:symlink_db'


namespace :deploy do

desc "Restart Application"
task :restart, :roles => :app do
run "touch #{deploy_to}/#{shared_dir}/tmp/restart.txt"
end

desc "Symlinks the database.yml"
task :symlink_db, :roles => :app do
run "ln -nfs #{deploy_to}/shared/config/database.yml #{release_path}/config/database.yml"
end

end

database.yml

development:
  adapter: mysql2
  database: db/development.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /tmp/mysql.sock

test:
  adapter: mysql2
  database: db/test.mysql2
  pool: 5
  timeout: 5000
  database: sample_app
  username: root
  socket: /tmp/mysql.sock

production:
  adapter: mysql2
  database: db/production.mysql2
  pool: 5

For Capistrano v2

Specify the location of your pem file

ssh_options[:keys] = ["/where/ever/it/is/key.pem"]

For Capistrano v3 ssh_options have changed slightly, but basic settings are pretty much same.

set :ssh_options, {
  keys: %w(/where/ever/it/is/key.pem),
  forward_agent: false,
  user: 'ubuntu'
}

how should we handle this when several developers deploy?

Steffen Brem Over a year ago

ssh_options[:keys] = [File.join(ENV["HOME"], "/.ssh/key.pem")]

Do you have "sudo" rights? Is user "ubuntu" in sudo group?

I had to add ssh_options[:keys] = ["/Users/Victoria/Documents/ServerKeys/key.pem"] to my deploy.rb file

If you can use "sudo" rights, you must allow it for your user (ubuntu). Problem is not in capistrano or RoR app. If you don't need "sudo" you can set: use_sudo false. My ubuntu settings for users: sudo:x:27:oliver,deployer,michal

When deploying to an ec2 instance you will not have sudo rights with the ubuntu user.

Change this:

set :use_sudo, true

To this:

set :use_sudo, false
