当我尝试运行部署设置时，为什么会出现 authenicationFailed？我使用 ssh 作为我的密码。我需要更改 database.yml 或 deploy.rb 中的任何内容吗？它们在下面列出。

$ 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)

部署.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,  "git@github.com: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

数据库.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
  timeout: 5000
  database: sample_app
  username: ubuntu

对于 Capistrano v2

指定 pem 文件的位置

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

Capistrano v3 ssh_options 略有变化，但基本设置几乎相同。

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

你有“sudo”的权利吗？用户“ubuntu”是否在 sudo 组中？

部署到 ec2 实例时，您将没有 ubuntu 用户的 sudo 权限。

改变这个：

set :use_sudo, true

对此：

set :use_sudo, false
