Question

我正在运行 cap production deploy:setup_config

我得到以下输出:

现在当我输入密码时。它显示密码，而且它甚至不起作用。任务如下:lib/capistano/tasks/setup_config.cap

namespace :deploy do
    task :setup_config do
        on roles(:app) do
        # make the config dir
        execute :mkdir, "-p #{shared_path}/config"
        full_app_name = fetch(:full_app_name)

        # config files to be uploaded to shared/config, see the
        # definition of smart_template for details of operation.
        # Essentially looks for #{filename}.erb in deploy/#{full_app_name}/
        # and if it isn't there, falls back to deploy/#{shared}. Generally
        # everything should be in deploy/shared with params which differ
        # set in the stage files
        config_files = fetch(:config_files)
        config_files.each do |file|
            smart_template file
        end

        # which of the above files should be marked as executable
        executable_files = fetch(:executable_config_files)
        executable_files.each do |file|
            execute :chmod, "+x #{shared_path}/config/#{file}"
        end

        # symlink stuff which should be... symlinked
        symlinks = fetch(:symlinks)

        symlinks.each do |symlink|
            execute "whoami && echo ${PATH}"
            sudo "ln -nfs #{shared_path}/config/#{symlink[:source]} # sub_strings(symlink[:link])}"
        end
    end
end
end

在 deploy.rb 中，我有以下关于 ssh 的内容:

set :pty, true
set :ssh_options, { forward_agent: true, :keys => %w(/home/SMD/.ssh/id_rsa)}
set :use_sudo, false
set :default_shell, '/bin/bash --login'

我不知道是什么问题。我也担心失败的代码。 ==>

提前致谢。

尝试将类似这样的内容添加到您的 deploy.rb 文件(或相应的部署环境文件)

set :password, ask('Server password', nil)
server 'xxx.xxx.xx.xx', user: 'root', port: 22, password: fetch(:password), roles: %w{web app db}, primary: true
