本文主要用于记录安装过程,以便日后查阅回顾. 之前在自己的树莓派上运行的一直是通过NOOB安装的Raspbian,但是本人平时更喜欢用Fedora作为开发和使用环境,而且Raspbian上的软件包通常更新比较缓慢.因为树莓派2代B型上市前,树莓派的芯片都是armv6或者更早的架构,只能运行ARM架构的Raspbian或者Fedora 18及更早版本.树莓派2代B型搭载的芯片架构是armv7,树莓派3代搭载的芯片架构是armv8,这两种芯片都能够运行ARM架构的Fedora 23,而仅运行Rasp…

raspberry pi买回来玩了一段时间,现在就记录一下入门遇到的一些问题吧. 首先是烧写镜像,和安装电脑系统是一样的道理. 先要有一个制作一个U启动盘.先将SD卡格式化,再用Win32DiskImager或dd命令将raspberry官方下载的镜像烧写进去(这种文档很多的,随便找一个都可以完成操作). 使用dd时可能很慢,那么请用: sudo dd if=/location/of/raspbian.img of=/dev/rdisk1 bs=1m /dev/rdisk1表示是U盘设备,最好不…

由于我使用树莓派的场景大多数是在没有显示器.只用terminal连接它的情况下,所以,它的IP地址有时会在重启之后变掉(DHCP的),导致我无法通过terminal连接上它.然后我又要很麻烦地登录路由器的管理界面里,去看它被分配到的新IP是什么,然后用terminal重连,太麻烦了,不是么?作为一个树莓派玩家,这种麻烦简直是无法接受的! 为了解决这个问题,我让Pi开机的时候,自动向我指定的Email发送一封邮件,告诉我它此次开机时的IP地址.步骤: 开机时执行一个脚本,检测网络可用性→网络通畅后…

使用htpdate同步时间 由于树莓派板子上没有 RTC 硬件和电池,因此树莓派上的系统时间重启是保存不了的.网上已经有人想到应对 NTP 被防火墙封掉类似的需求了,开源的 htpdate 命令直接使用 HTTP 协议来进行系统时间同步,项目主页在这里: https://github.com/iridium77/htpdate htpdate 的原理也非常简单,直接解析 HTTP 协议头中的服务器时间信息,然后设置本地时间,我们来看百度返回的 HTTP 头: HTTP/1.1 200 OK Da…
