mikadonic-建立互信

在控制主机中新建主机的公钥
[root@Ansible .ssh]# ssh-keygen -t rsa

[root@Ansible .ssh]# cp /root/.ssh/id_rsa.pub /var/www/html/download/authorized_keys.1

其他主机上执行下载命令,且追加到authorized_keys文件中
wget -P /root/.ssh/ 168.1.3.18/download/authorized_keys.1
cat /root/.ssh/authorized_keys.1 >>/root/.ssh/authorized_keys
rm -f /root/.ssh/authorized_keys.1

wget -P /root/.ssh/ 168.1.3.18/download/authorized_keys
