我正在嘗試使用Capistrano部署Rails應用程序。我遵循教程How to Deploy a Rails 4 App with Git and Capistrano。然而，當我運行cap production deploy:check，它給了我這個錯誤：運行部署時驗證錯誤：檢查
INFO[349a4b8d] Running /usr/bin/env mkdir -p /tmp/app_name/ on xxx.xx.xxx.xxx
DEBUG[349a4b8d] Command: /usr/bin/env mkdir -p /tmp/app_name/
INFO[cd49f0ac] Running /usr/bin/env mkdir -p /tmp/app_name/ on example.com
DEBUG[cd49f0ac] Command: /usr/bin/env mkdir -p /tmp/app_name/
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing on host xxx.xx.xxx.xxx: Authentication failed for user @xxx.xx.xxx.xxx
我首先想到的是，我確實需要使用sudo，但MKDIR不應該需要在/ tmp /須藤。我的第二個想法是它需要ssh的密碼，但我使用公鑰在開發計算機和服務器之間使用ssh。有任何想法嗎？
這裏是我的config/deploy.rb：
lock '3.2.1'
set :application, 'app_name'
set :repo_url, '[email protected]:remote/app_name.git'
set :scm, :git
set :user, 'deploy'
set :use_sudo, false
set :stage, :production
set :rails_env, 'production'
set :deploy_via, :remote_cache
set :keep_releases, 5
set :ssh_options, { forward_agent: true }
set :pty, true
server 'xxx.xx.xxx.xxx', roles: [:app, :web, :db], primary: true
namespace :deploy do
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
# Your restart mechanism here, for example:
# execute :touch, release_path.join('tmp/restart.txt')
end
end
after :publishing, :restart
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
# within release_path do
# execute :rake, 'cache:clear'
# end
end
end
end
我使用Ruby 2.1.0，Rails的4.1.4和3.2.1 Capistrano的。
