Expect ssh免秘钥登入自动脚本（ssh-copy-id、expect免交互输入脚本）
无**登录的自动脚本实现：
vim auto_ssh.sh
|
#!/usr/bin/expect
set timeout 10
set username [lindex $argv 0]
set password [lindex $argv 1]
set hostname [lindex $argv 2]
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub
expect {
#first connect, no public key in ~/.ssh/known_hosts
“Are you sure you want to continue connecting (yes/no)?” {
send “yes\r”
expect “password:”
send “$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
然后执行下述命令即可。
./auto_ssh.sh root 123456 192.168.10.162
