我有代碼要求我連接到一臺服務器,rsync連接到另一臺服務器,然後連接到第二臺服務器並在其上運行一堆命令。但是沒有失敗,第二個SSH連接會引發'do_open_failed': open failed (1) (Net::SSH::ChannelOpenFailed)
錯誤。我在這裏做錯了什麼,有沒有辦法正確關閉第一個連接,使第二個連接?SSH連接一個接一個,第二個連接失敗
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,第二連接將代表第一個是不存在運行正常。但很顯然,我需要兩者都在做什麼。 – Magicmarkker
您是否嘗試過使用'ssh.loop'而不是'channel.wait'?我不知道是否有區別。 –
另外,'exec'不會阻止。在第二個啓動塊中,請嘗試使用'exec!',或者使'ssh'等待命令完成。 –
