Ruby on rails 使用Mina时无法通过ssh连接到服务器

我尝试使用来自动化RubyonRails应用程序的部署过程。我在我的

config/deploy.rb

文件中定义了一个ssh用户，如下所示：

set :user, 'unix-username'

require 'mina/rails'
require 'mina/git'
require 'mina/rvm'

set :application_name, 'app-name'
set :domain, 'ip-address-of-my-server'
set :user, 'unix-username'
set :deploy_to, "/home/#{fetch(:user)}/app"
set :repository, 'git@github.com:path/to/repo.git'
set :branch, 'master'
set :rvm_use_path, '/etc/profile.d/rvm.sh'

set :execution_mode, :exec if RbConfig::CONFIG['host_os'] =~ /mswin|mingw/

# Optional settings:
#   set :user, 'foobar'          # Username in the server to SSH to.
#   set :port, '30000'           # SSH port number.
#   set :forward_agent, true     # SSH forward_agent.

set :shared_files, fetch(:shared_files, []).push('config/database.yml', 'config/secrets.yml')

task :remote_environment do
  ruby_version = File.read('.ruby-version').strip
  raise "Couldn't determine Ruby version: Do you have a file .ruby-version in your project root?" if ruby_version.empty?

  invoke :'rvm:use', ruby_version
end

task :setup do

  in_path(fetch(:shared_path)) do

    command %[mkdir -p config]

    # Create database.yml for Postgres if it doesn't exist
    path_database_yml = "config/database.yml"
    database_yml = %[production:
  database: #{fetch(:user)}
  adapter: postgresql
  pool: 5
  timeout: 5000]
    command %[test -e #{path_database_yml} || echo "#{database_yml}" > #{path_database_yml}]

    # Create secrets.yml if it doesn't exist
    path_secrets_yml = "config/secrets.yml"
    secrets_yml = %[production:\n  secret_key_base:\n    #{`bundle exec rake secret`.strip}]
    command %[test -e #{path_secrets_yml} || echo "#{secrets_yml}" > #{path_secrets_yml}]

    # Remove others-permission for config directory
    command %[chmod -R o-rwx config]
  end

end

desc "Deploys the current version to the server."
task :deploy do
  deploy do
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    on :launch do
      # command "sudo service #{fetch(:user)} restart"
    end
  end
end

但是，当我调用

mina setup

时，用户名没有设置，因此脚本尝试使用本地dev maschine的windows用户名ssh到我的服务器（这是默认行为，我知道，当没有提供用户名时）

如何才能成功使用脚本

我的

deploy.rb

文件：

set :user, 'unix-username'

require 'mina/rails'
require 'mina/git'
require 'mina/rvm'

set :application_name, 'app-name'
set :domain, 'ip-address-of-my-server'
set :user, 'unix-username'
set :deploy_to, "/home/#{fetch(:user)}/app"
set :repository, 'git@github.com:path/to/repo.git'
set :branch, 'master'
set :rvm_use_path, '/etc/profile.d/rvm.sh'

set :execution_mode, :exec if RbConfig::CONFIG['host_os'] =~ /mswin|mingw/

# Optional settings:
#   set :user, 'foobar'          # Username in the server to SSH to.
#   set :port, '30000'           # SSH port number.
#   set :forward_agent, true     # SSH forward_agent.

set :shared_files, fetch(:shared_files, []).push('config/database.yml', 'config/secrets.yml')

task :remote_environment do
  ruby_version = File.read('.ruby-version').strip
  raise "Couldn't determine Ruby version: Do you have a file .ruby-version in your project root?" if ruby_version.empty?

  invoke :'rvm:use', ruby_version
end

task :setup do

  in_path(fetch(:shared_path)) do

    command %[mkdir -p config]

    # Create database.yml for Postgres if it doesn't exist
    path_database_yml = "config/database.yml"
    database_yml = %[production:
  database: #{fetch(:user)}
  adapter: postgresql
  pool: 5
  timeout: 5000]
    command %[test -e #{path_database_yml} || echo "#{database_yml}" > #{path_database_yml}]

    # Create secrets.yml if it doesn't exist
    path_secrets_yml = "config/secrets.yml"
    secrets_yml = %[production:\n  secret_key_base:\n    #{`bundle exec rake secret`.strip}]
    command %[test -e #{path_secrets_yml} || echo "#{secrets_yml}" > #{path_secrets_yml}]

    # Remove others-permission for config directory
    command %[chmod -R o-rwx config]
  end

end

desc "Deploys the current version to the server."
task :deploy do
  deploy do
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    on :launch do
      # command "sudo service #{fetch(:user)} restart"
    end
  end
end

您使用哪一版本的mina？1.2.2，但也使用1.2.3进行了测试。您可以

捆绑打开mina

，并在

/lib/mina/backend/remote.rb

中使用

p fetch（：user）

，或者使用byebug或pry-before或任何其他您喜欢调试问题的技术。请分享用户在ssh方法中的作用。另一个建议是删除与一般mina配置无关的代码，并使用最小配置运行mina，而该配置实际上不起任何作用。通过测试mina是否能正确使用最小配置。通过这种方式，您可以定位问题的根源。
