1.自动化配置 dns 服务器

#backup establish 创建 backup 目录

的属主和属组主，如果不对应的话客户端无法把文件推送过来

#rsync password file 创建虚拟账号的密码文件

echo "rsync_backup:oldboy" >/etc/rsync.password &&\ #对应 rsync_backup

chmod 600 /etc/rsync.password &&\ #因为 oldboy 是可读的字节但是文件类型

ls -l /etc/rsync.password &&\ #查看权限

#local daemon

export

#rsync password file

echo "oldboy" >/etc/rsync.password &&\ #在/etc/rsync.password 留下密码

就可以了密码为：oldboy

chmod 600 /etc/rsync.password &&\ #因为有密码考虑到安全问题所以权限也
