使用Ruby通过SSH连接运行sudo命令时遇到问题:

require 'net/ssh'
Net::SSH.start("myserver.com", "login", :password => "pass")  do |ssh|
test = ssh.exec! 'sudo -iu admin /folder/script.sh'
puts test

我接下来看到的结果是:“sudo:对不起，您必须有一个tty才能运行sudo \ n”

但是当我运行此命令时:

sudo -iu admin /folder/script.sh

在PUTTY中，使用密码“pass”连接到服务器“myserver.com”。在这种情况下，sudo命令成功运行并完成。

如何使用TTY在Ruby脚本中运行此sudo命令？

最佳答案

这为我工作:

require 'net/ssh'
host = "your.host.com"
user = "user"
password = "your pass"

command = "ls"

Net::SSH.start(host, user, password) do |session|

  session.open_channel do |channel|
    channel.on_data do |ch, data|
      puts "data received: #{data}"
    end

    channel.request_pty do |ch, success|
      if success
        puts "pty successfully obtained"
        ch.exec(command)
      else
        puts "could not obtain pty"
      end
    end

  end

  session.loop
end
