"Sudo"失败并显示"sudo require tty"；从PuTTY命令行执行时 [英] "Sudo" fails with "sudo requires a tty" when executed from PuTTY command line

问题描述

我正在尝试使用PuTTY在远程CentOS计算机上运行一些命令.我正在使用以下命令:

I'm trying to run some commands on a remote CentOS machine using PuTTY. I'm using the following command:

putty.exe -ssh [IP] -l [user] -pw [password] -m [Script]

其中 [Script] 是一个 .txt 文件，其中包含我要运行的命令.问题是其中一个命令需要 sudo ，当PuTTY尝试运行它时，我会收到错误消息:

Where [Script] is a .txt file containing the commands I want to run. The issue is that one of the commands requires sudo, and when PuTTY tries to run it I get an error:

sudo 需要一个 tty

sudo requires a tty

让我感到困惑的是，如果我在没有提供脚本的情况下启动会话，然后手动运行脚本中的命令，则效果很好.我尝试使用 -load 而不是 -ssh ，但这没什么区别.

The thing that's confusing me is that if I start the session without giving a script, then run the commands from the script manually, it works fine. I've tried using -load instead of -ssh, and it made no difference.

出于安全原因，我无法更改 sudoers 文件中的 requiretty 设置，这是我唯一能找到的解决方案.还有其他选择吗?

I can't change the requiretty setting in my sudoers file for security reasons, which is the only solution I've been able to find. Is there another option?

推荐答案

sudo 需要TTY/交互式会话.

The sudo requires TTY/interactive session.

相反，PuTTY/Plink -m 开关默认情况下使用非交互式会话.

On the contrary the PuTTY/Plink -m switch uses non-interactive session by default.

使用 -t 开关以覆盖它.

Use the -t switch to override that.

putty.exe -ssh [IP] -l [user] -pw [password] -t -m [Script]
