我正在使用 pssh 在多台服务器上运行安装。在安装过程中，我希望脚本提示用户输入密码，但这并没有发生。
当我在单个服务器上运行脚本时，它会成功，但是，当我通过以下命令使用 pssh 时，它会失败。
pssh -h hostfile.txt -t 100000000 -A -l jolaoosup -P -I <./scripts
使用的脚本如下所示：
#!/bin/bash
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-7.0.tar.gz --no-check-certificate
echo "Download complete"
tar xzf setuptools-7.0.tar.gz
echo "File untarred"
cd setuptools-7.0
echo "Changed directory to setup Tool"
python setup.py install
echo "setup.py installed"
cd /home/jolaoosup/
echo "Changed into Home directory"
wget https://bootstrap.pypa.io/get-pip.py
echo "Pip download successful"
**read -sp "Password: " passvar** -> when it failed to prompt for password
echo
echo Thank you for your login details
echo $passvar | dzdo -S python get-pip.py
echo "get-pip installed"
echo $passvar | dzdo -S easy_install --upgrade numpy
echo "numpy upgrade completed"
echo $passvar | dzdo -S easy_install --upgrade pyparsing
echo "pyparsing upgrade completed"
echo $passvar | dzdo -S pip install numpy scipy matplotlib pandas statsmodels
echo "All available packages installed"
