在很多實踐項目中,我們經常會通過SSH來進行認證,如通過SSH拷貝文件,雖然我們可以使用公鑰與私鑰實現ssh 無密碼登錄,在不同的服務器上又需要配對相應的密鑰,切換用戶麻煩等問題,在一些需要交互但會涉及到批量處理的時候,通過shell 密碼輸入不顯示,Shell輸出內容不顯示密碼,Shell實現有密碼自動登錄會大大的提高工作效率

一,不顯示SSH輸入的密碼

stty?-echo read?PASSWORD stty?echo?#關閉輸入不顯示

參考網站:http://www.jb51.net/article/40654.htm

二,通過SSH輸入的密碼實現自動登錄

sshpass?-p?$PASSWORD??ssh?root@1.2.3.4????#實現SSH在shell腳本里自動登錄

參考網站:http://blog.csdn.net/gsnumen/article/details/7293274

CentOS6安裝sshpass:

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

三,輸出信息時不顯示密碼信息

awk?'{$3="***"}1'?FS='?'?OFS='?'?/dev/shm/tempCMD??#將第三列輸入的SSH密碼在屏幕顯示時,顯示為*
