为什么通过ssh的mysql命令不提示输入密码？

Question

I'm attempting to run a command like the following:

ssh user@host 'mysql -u dbuser -p database < ~/data.sql'

I'm expecting it to prompt me a password like it normally would if you're on that host.

However, it does not do that. Is there an ssh argument I'm missing or something?

Another thing to note is that if you remove the < ~/data.sql , the prompt does appear as expected.

您需要创建一个伪终端，以便mysql可以从/dev/tty而不是标准输入中读取：

ssh -t user@host 'mysql -u dbuser -p database < ~/data.sql'
