標籤：shell   ssh   bash   密碼   

預設遠程主機上已經存在 ～/.ssh 目錄。在自己PC上執行下面指令碼，輸入伺服器使用者名稱和ip地址，下次登入可實現無密碼登入。

#!/bin/bashid_res_pub=~/.ssh/id_rsa.pubif [ ! -f "$id_res_pub" ];then    ssh-keygen -t rsaelse    echo "id_rsa.pub is exist!"fiechoecho "Enter remote host user name"read rnameechoecho "Enter remote host ip address"read ip_addressechoecho "You remote host :"echo "${rname}@${ip_address}"cat .ssh/id_rsa.pub | ssh ${rname}@${ip_address} 'cat >> .ssh/authorized_keys'
