尝试使用Puma / Nginx / Capistrano在EC2实例上部署Rails应用程序。我关注this tutorial.
这是我的第一次部署，不确定到底发生了什么。从控制台输出来看，似乎我的ssh配置存在问题，但我真的不确定任何帮助会受到高度赞赏。
这是deploy.rb
server '52.206.222.73', roles: %w{web app db}, primary: true
set :repo_url, 'git@example.com:username/myapp.git'
set :application, 'myapp'
set :user, 'deploy'
set :puma_threads, [4, 16]
set :puma_workers, 0
# Don't change these unless you know what you're doing
set :pty, true
set :use_sudo, false
set :stage, :production
set :deploy_via, :remote_cache
set :deploy_to, "/home/#{fetch(:user)}/#{fetch(:application)}"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_access_log, "#{release_path}/log/puma.error.log"
set :puma_error_log, "#{release_path}/log/puma.access.log"
set :ssh_options, { forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/id_rsa.pub) }
set :puma_preload_app, true
set :puma_worker_timeout, nil
set :puma_init_active_record, true # Change to false when not using ActiveRecord
## Defaults:
# set :scm, :git
# set :branch, :master
# set :format, :pretty
# set :log_level, :debug
# set :keep_releases, 5
## Linked Files & Directories (Default None):
# set :linked_files, %w{config/database.yml}
# set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
namespace :puma do
desc 'Create Directories for Puma Pids and Socket'
task :make_dirs do
on roles(:app) do
execute "mkdir #{shared_path}/tmp/sockets -p"
execute "mkdir #{shared_path}/tmp/pids -p"
end
end

答案 0 :(得分：2)
运行这两个命令以通过您的系统授予git访问权限
eval ssh-agent
ssh-add ~/.ssh/id_rsa
这些命令假设你有远程git服务器上的ssh密钥（bitbucket / github / other）
答案 1 :(得分：1)
我很惊讶Git没有更具描述性的错误消息。但是，git ls-remote命令由于某种原因失败。在没有任何错误消息的情况下，最好的猜测是Git无法访问远程存储库。
这可能是因为：
在本地计算机上（即运行cap命令的位置），尝试通过SSH手动运行相同的Git命令，看看会发生什么：
ssh -A -i ~/.ssh/id_rsa.pub deploy@52.206.222.73 git ls-remote --heads git@example.com:username/amharic-web.git
