20.28 expect脚本远程登陆

expect脚本远程登陆

• yum install -y expect

• 自动远程登陆

[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  //脚本结束

• 在expect 定义变量，用set
• 这个文件是就保证登陆信息的，清空的话，从新远程登陆ssh 会有提示 /root/.ssh/known_hosts
  exp_continue 表示继续 \r 表示换行 interact 继续停留在这台机器，不退出

加入执行权限

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