在很多实践项目中,我们经常会通过SSH来进行认证,如通过SSH拷贝文件,虽然我们可以使用公钥与私钥实现ssh 无密码登录,在不同的服务器上又需要配对相应的密钥,切换用户麻烦等问题,在一些需要交互但会涉及到批量处理的时候,通过shell 密码输入不显示,Shell输出内容不显示密码,Shell实现有密码自动登录会大大的提高工作效率

一,不显示SSH输入的密码

stty -echo
read PASSWORD
stty echo #关闭输入不显示

二,通过SSH输入的密码实现自动登录

sshpass -p $PASSWORD  ssh root@1.2.3.4    #实现SSH在shell脚本里自动登录

参考网站:http://blog.csdn.net/gsnumen/article/details/7293274

CentOS6安装sshpass:

cd /etc/yum.repos.d/
wget http://download.opensuse.org/repositories/home:Strahlex/CentOS_CentOS-6/home:Strahlex.repo
yum install sshpass

三,输出信息时不显示密码信息

awk '{$3="***"}1' FS=' ' OFS=' ' /dev/shm/tempCMD  #将第三列输入的SSH密码在屏幕显示时,显示为*
