linux自动分发秘钥到每台主机

一、需要安装expect软件

# yum install expect -y

二、执行脚本+IP地址将秘钥分发到指定主机上

# cat add_host.sh 
#!/usr/bin/expect
set ip [lindex $argv 0]
set password Admin@9009
spawn ssh-copy-id -i /home/admin/.ssh/id_rsa.pub admin@${ip}
expect {
    "(yes/no)" { send "yes\n"; exp_continue }
    "Password:" { send "$password\n"  }
}
interact

# sh add_host.sh 192.168.0.6
