20.28 expect腳本遠程登陸

expect腳本遠程登陸

• yum install -y expect

• 自動遠程登陸

[root@aminglinux-02 sbin]# vim 1.expect

#! /usr/bin/expect
set host "192.168.133.132"
set passwd "123456"
spawn ssh root@$host   
expect {
"yes/no" { send "yes\r"; exp_continue}  //
"password:" { send "$passwd\r" }   
}
interact  //腳本結束

• 在expect 定義變量，用set
• 這個文件是就保證登陸信息的，清空的話，從新遠程登陸ssh 會有提示 /root/.ssh/known_hosts
  exp_continue 表示繼續 \r 表示換行 interact 繼續停留在這臺機器，不退出

加入執行權限

[root@aminglinux-02 sbin]# ./1.expect
-bash: ./1.expect: 權限不夠
[root@aminglinux-02 sbin]# chmod a+x 1.expect

• 成功登陸

[root@aminglinux-02 sbin]# ./1.expect
spawn ssh root@192.168.133.130
