Os 7 expect模拟交互ssh到另一台主机

安装expect

[root@localhost ~]# yum -y install expect

查看expect位置

[root@localhost ~]# whereis expect

编辑脚本

[root@localhost ~]# vim /shell/ssh.exp

#!/usr/bin/expect
spawn ssh root@192.168.33.137
expect {
        "yes/no" { send "yes\r";exp_continue}
        "password" {send "123456\r"}
}
expect "]#"
send "ifconfig ens33"
expect eof

添加执行条件

[root@localhost shell]# chmod +x /shell/ssh.exp

执行测试

[root@localhost shell]# cd /shell/
[root@localhost shell]# ./ssh.exp

如果之前连接过导致连接失败，删除之后再测试

[root@localhost shell]# rm -rf /root/.ssh/known_hosts
