关于树莓派的介绍以及使用可参考官方网站

单板Linux

随着嵌入式Linux越来越流行,目前很多厂商都在致力于做单板主机,因此市面上也有很多产品可供选择.其中最具有活力的便是树莓派了,连在Mr Robot一剧中都被主人公拿来”打广告”.其他诸如香蕉派,香橙派,菠萝派等等pi都有开发团队在开发和维护,有兴趣的可以逐个折腾或者吊的自己绘制PCB制作.

访问方式

毫无疑问Web是目前最流行的可视化途径,但是在Linux中最最适合的还是属于console.一般默认在刷入固件之后会默认开启sshd服务,此时便可以通过网络接口ssh连接工具访问树莓派.当然,如果没有开启或者没有通过扫描等方式获取到树莓派的IP地址,则可以借助显示设备或者默认的串口来查看信息,可供选择的是显示接口为HDMI和专用显示接口,一般我们会用HDMI转VGA转接口来接显示屏,此后配置好后便可以当小型服务器用了.

配置远程桌面

有些时候console解决不了的时候就必须启用rdp了.Linux中可供选择的桌面系统还是很多的,其中xfce作为流行的轻量级的桌面系统深受好评.一般我们仅仅需要开启xrdp服务即可采用微软的mstsc工具来连接Linux主机,但xrdp貌似也是在本地封装vnc服务,因此当vnc服务出现问题的时候即便3389端口处于监听状态也是没辙.无奈只好谷歌.报错信息如下:

找了好几个论坛之后又装了好多貌似多余的东西,最后发现仅仅需在这里键入sudo apt-get install xfonts-base即可解决字体问题了.

可以看到服务已经开启了,5901端口处于监听状态.再次mstsc之后发现error没了,问题解决.

总结

遇到问题还是要有折腾的情怀,虽然还不知所以然,但是能够解决这个问题也不辜负搬砖的身份…为了不犯第二次错误,便记录下了本文.
