MAC终端密钥登录自动输入密码

升级MAC系统后，发现用于MAC终端ssh服务器的登录脚本无法正常执行了，表现为：需要手动输入密钥密码，于是重新整理一下，恢复正常，在此记录一下：

#!/usr/bin/expect -f
spawn ssh-add -D
expect "*removed."
spawn ssh-add -l
expect "*identities."
spawn ssh-add /Users/alsoalso/keys/RSA_Key01
expect "*RSA_Key01" {send "密钥密码 ";}
expect "Identity added:"
spawn ssh SSH用户@IP地址 -pSSH端口 -i /Users/alsoalso/keys/RSA_Key01
expect "*yes/no*" { send "yes "; exp_continue }
interact

说明一下：

#!/usr/bin/expect -f 指定expect, 需要安装

spawn ssh-add -D 删除已add的密码，mac终端对添加的条目有限制，所以每次都初始化一下

expect "*removed." 根据上一步的执行反馈，获取关键字用于执行下一步的条件

spawn ssh-add -l 列出密钥列表，非必须

expect "*identities." 根据上一步的执行反馈，获取关键字用于执行下一步的条件，非必须

spawn ssh-add /Users/alsoalso/keys/RSA_Key01 添加密钥文件

expect "*RSA_Key01" {send "密钥密码 ";} 输入密钥密码

expect "Identity added:" 判断密钥是否登录成功

spawn ssh SSH用户@IP地址 -pSSH端口 -i /Users/alsoalso/keys/RSA_Key01 连接服务器

expect "*yes/no*" { send "yes "; exp_continue } 如果首次连接服务器，会有确认

interact 命令执行完成后保持登录在远程服务器上

20180322更新：直接切换为root用户

#!/usr/bin/expect -f

spawn ssh-add -D

expect "*removed."

spawn ssh-add -l

expect "*identities."

spawn ssh-add /Users/alsoalso/keys/RSA_Key00

expect "*RSA_Key00" {send "mima ";}

expect "Identity added:" { spawn ssh sshusername@ip -pssh端口 -i /Users/alsoalso/keys/RSA_Key00 }

expect "sshusername@hostname ~" { send "su " }

expect "密码" { send "rootmima " }

expect "*yes/no*" { send "yes "; exp_continue }
