只需生成一个SSH密钥:

ssh-keygen -t rsa -C "your_email@youremail.com"

复制~/.ssh/id_rsa.pub的内容 最后将它添加到远程计算机~/.ssh/authorized_keys

确保远程机器拥有~的权限0700。~/.ssh/authorized_keys文件夹为0600

Make sure password authentication is enabled on the target server. If it runs Ubuntu, then open /etc/ssh/sshd_config on the server, find lines PasswordAuthentication=no and comment all them out (put # at the start of the line), save the file and run sudo systemctl restart ssh to apply the configuration. If there is no such line then you're done. Add -o PreferredAuthentications="password" to your scp command, e.g.: scp -o PreferredAuthentications="password" /path/to/file user@server:/destination/directory

上面提到的所有解决方案都可以工作，只有当你安装了应用程序，或者你应该有管理权限安装除sshpass。

我发现这个非常有用的链接可以简单地在后台启动scp。

$ nohup scp file_to_copy user@server:/path/to/copy/the/file > nohup.out 2>&1

没有人提到它，但是Putty scp (pscp)有一个-pw选项作为密码。

文档可以在这里找到:https://the.earth.li/~sgtatham/putty/0.67/htmldoc/Chapter5.html#pscp

使用sshpass:

sshpass -p "password" scp -r user@example.com:/some/remote/path /some/local/path

所以密码不会显示在bash历史记录中

sshpass -f "/path/to/passwordfile" scp -r user@example.com:/some/remote/path /some/local/path

上面的操作将路径的内容从远程主机复制到本地。

安装:

ubuntu / debian 安装sshpass centos / fedora Yum安装sshpass MAC / macports 端口安装sshpass MAC / brew brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

一旦像上面解释的那样设置了ssh-keygen，就可以这样做了

SCP -i ~/。Ssh /id_rsa /local/path/to/file remote@ip.com:/path/in/remote/server/

如果希望减少每次输入的次数，可以修改.bash_profile文件并将

alias remote_scp='scp -i ~/.ssh/id_rsa /local/path/to/file remote@ip.com:/path/in/remote/server/

然后从您的终端执行source ~/.bash_profile。然后，如果您在终端中输入remote_scp，它应该运行没有密码的scp命令。
