一、环境描述
操作系统: CentOS release 6.5 (Final)
机器A:10.10.10.102
机器B:10.10.10.101
业务要求:将B数据中的文件非实时同步到A机器中。
二、操作步骤
建立B到A的信任关系 a、生成私钥和公钥 [iyunv@jy .ssh]# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key(/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: ……
b、将B的公钥放到A的目录中 c、修改B中的sshd_config配置,将以下注释取消 RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys d、重启B中的sshd服务 [iyunv@hq ~]# service sshd restart 停止 sshd:[确定] 正在启动 sshd:[确定] e、ssh登陆A机器不需要密码
