無密鑰登錄的自動腳本實現：

vim auto_ssh.sh

#!/usr/bin/expect  
set timeout 10  
set username [lindex $argv 0]  
set password [lindex $argv 1]  
set hostname [lindex $argv 2]  
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub $username@$hostname
expect {
            #first connect, no public key in ~/.ssh/known_hosts
            "Are you sure you want to continue connecting (yes/no)?" {
            send "yes\r"
            expect "password:"
                send "$password\r"
            }
            #already has public key in ~/.ssh/known_hosts
            "password:" {
                send "$password\r"
            }
            "Now try logging into the machine" {
                #it has authorized, do nothing!
            }
        }
expect eof

chmod 777 auto_ssh.sh

然後執行下述命令即可。

./auto_ssh.sh root 123456 192.168.10.162

試驗結果：

162機器上傳看：

成功！

# cat ip.txt
192.168.191.166
192.168.191.167
192.168.191.168
192.168.191.169

# cat ip-pass.txt
192.168.191.166 password1
192.168.191.167 password2
192.168.191.168 password3
192.168.191.169 password4

刪除歷史訪問秘鑰信息，以免有變：

for i in `cat ip.txt`;do sed -i ‘/‘$i‘/d‘ ~/.ssh/known_hosts;done

批量添加互信服務器：

while read IP PASS;do ./auto_ssh.sh root $PASS $IP;done < ip-pass.txt
