sudo抱歉,你必须有一个tty来运行sudo

Question

我编写了一个bash脚本,它运行到每台机器并运行一组命令.我正在使用在该计算机上具有sudo privlidges的用户iis.但是,当我运行sudo yum命令时,我得到sudo:抱歉,你必须有一个tty来运行sudo.

不确定是什么问题？我使用-t命令强制但它仍然无法正常工作

bash脚本

#!/bin/bash
INPUT=ccidetails.csv
OLDIFS=$IFS
IFS=,
[ ! -f $INPUT ] && { echo "$INPUT file not found"; exit 99; }
while read privateip password
do
echo $privateip
scp /home/Data/Test.c iis@$privateip:/tmp
sshpass -p$password </dev/null ssh -t -o "StrictHostKeyChecking no" iis@$privateip "

hostname
cd /tmp
gcc Test.c -o TEST
./TEST
sudo yum -y update glibc
gcc Test.c -o TEST
./TEST
exit

" >> output.txt

done < $INPUT
IFS=$OLDIFS

错误:

sudo: sorry, you must have a tty to run sudo

在远程主机上注释/ etc/sudoers下面的行:

 grep tty /etc/sudoers
#Defaults    requiretty

这将允许你继续.确保您了解这样做的后果:

man sudoers | grep -i requiretty  -A 5
       requiretty      If set, sudo will only run when the user is logged in
                       to a real tty.  When this flag is set, sudo can only be
                       run from a login session and not via other means such
                       as cron(8) or cgi-bin scripts.  This flag is off by
                       default.

如果您不想全局禁用requiretty,则可以为特定用户禁用它:

例:

Defaults    requiretty
Defaults:your_username_goes_here !requiretty
