我在脚本中有一个简单的远程ssh命令nohupssh.sh

sleep 30
ssh -v  -l developer server11  "/usr/local/jdk1.7.0_45/bin/jmap -histo:live 1770;"

我按如下方式运行脚本：

nohup nohupssh.sh > out.log 2>&1 &

当我如上所示执行它时，jmap实用程序在远程服务器上成功执行。但是，如果按照上面所示执行它并退出bashshell，则会出现如下所示的错误

请注意，我在本地和远程服务器中都有一个正确格式化的授权密钥。还请注意，这两台服务器中都没有id_rsa，因为这些服务器是共享的

我试过很多组合：

ssh -v -A -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o GlobalKnownHostsFile=/dev/null server11 ....

但是没有用。我仔细检查了ssh的手册页，寻找线索，尝试了各种选择。我认为必须有一个或一组ssh选项来解决这个问题。真正的脚本（而不是上面的节略）也有scp。因此，我希望我所回避的选项对scp和ssh都有效

由于您没有公钥设置（“没有id_rsa”），因此需要输入密码才能访问远程服务器，但您已断开了stdin:
读取\u密码：无法打开/dev/tty:没有这样的设备或地址
SSH不太适合黑客自动输入密码，因此如果您无法在上面添加id_rsa，最好是在输入远程服务器的密码后进行后台处理和分离。请尝试^Z:
运行nohup nohupssh.sh>out.log 2>&1
等待30秒，然后输入远程服务器密码
击中控制-Z
运行bg%1
