我有代码要求我连接到一台服务器,rsync连接到另一台服务器,然后连接到第二台服务器并在其上运行一堆命令。但是没有失败,第二个SSH连接会引发'do_open_failed': open failed (1) (Net::SSH::ChannelOpenFailed)
错误。我在这里做错了什么,有没有办法正确关闭第一个连接,使第二个连接?SSH连接一个接一个,第二个连接失败
Net::SSH.start(self.from_creds['host'], self.from_creds['user'], :password => self.from_creds['password']) do |ssh|
channel = ssh.open_channel do |ch|
ch.exec "/usr/bin/rsync -e ssh -varuzP --exclude=sys-export --delete #{self.from_creds['filepath']}/#{self.client_id}/ #{self.scp_to}/#{new_client_id}" do |ch, success|
raise "could not execute command" unless success
# "on_data" is called when the process writes something to stdout
ch.on_data do |c, data|
$stdout.print data
end
# "on_extended_data" is called when the process writes something to stderr
ch.on_extended_data do |c, type, data|
$stderr.print data
end
ch.on_close { puts "done!" }
end
end
channel.wait
end
Net::SSH.start(self.to_creds['host'], self.to_creds['user'], :password => self.to_creds['password']) do |ssh1|
# Do some other stuff here
tmp_path = "#{self.to_creds['filepath']}/tmp/#{Time.now.to_i}"
ssh1.exec "mkdir -p #{tmp_path}"
ssh1.exec "cd #{self.to_creds['filepath']}/#{new_client_id}"
end
而且,第二连接将代表第一个是不存在运行正常。但很显然,我需要两者都在做什么。 – Magicmarkker
您是否尝试过使用'ssh.loop'而不是'channel.wait'?我不知道是否有区别。 –
另外,'exec'不会阻止。在第二个启动块中,请尝试使用'exec!',或者使'ssh'等待命令完成。 –
