使用ruby gem net-ssh-multi可一次在多个服务器上执行sudo命令
|
在上一个问题中，我弄清楚了如何在多个服务器上启动经过密码验证的ssh会话以运行单个命令。现在，我需要能够执行\“ sudo \”命令。问题是，net-ssh-multi没有分配伪终端（pty），而sudo需要运行该伪终端，从而导致以下错误：
[127.0.0.1：stderr] sudo：抱歉，您必须具有tty才能运行sudo
根据文档，伪终端可以通过对通道对象的方法调用来分配，但是，以下代码不起作用：上面会产生\“ no tty \”错误：
require \'net/ssh\'
require \'net/ssh/multi\'
Net::SSH::Multi.start do |session|
# define the servers we want to use
my_ticket.servers.each do |session_server|
session.use session_server , :user => user_name , \\
:password => user_pass
end
# execute commands on all servers
session.exec \'sudo ls /root\' do |channel, stream, data|
if data =~ /^\\[sudo\\] password for user:/
channel.request_pty # <- problem must be here.
channel.send_data user_pass
end
end
# run the aggregated event loop
session.loop
end

channel.request_pty do |c, success| if success command = \"sudo YOUR_COMMAND\" c.exec(command) do |c, success| # Some processing end end end坍锭嘉韭蓝
您也可以从/ etc / sudoers中删除tty请求。为此，运行并注释旗低饶彤
Net::SSH::Multi.start do |session| # define the servers we want to use my_ticket.servers.each do |session_server| session.use session_server , :user => my_ticket.user_name , \\ :password => my_ticket.user_pass end session.open_channel do |channel| channel.request_pty do |c, success| raise \"could not request pty\" unless success channel.exec \"sudo YOUR_COMMAND\" channel.on_data do |c_, data| if data = /\\[sudo\\]/ channel.send_data(@password + \"\\n\") end puts data end end end # run the aggregated event loop session.loop end
