在 armbian 上安装 xcfe、浏览器和 VNC 当远程桌面用。二级标题最近买了个RK3568的矿机盒子，配置是4G+32G(emmc)，额外带一张64G的SanDisk Extreme SD卡。默认里面应该就是armbian，让店家额外刷了干净版本的armbian。刚进系统时会要求设置Root密码，我没有创建额外的用户，并选择了bash作为默认shell。更换软件源参考清华大学开源软件镜像站使用帮助：Armbian 软件仓库Debian 软件源配置 xfce 和 VNC安装xfce和vnc1234apt updateapt install xrdp -yapt install xfce4 xfce4-goodies -yapt install tigervnc-standalone-server -y初始化VNC：1vncserver输入两次密码然后会询问你是否创建仅观看（View-only）的密码，输入仅观看密码登录到VNC的用户只能观看远程桌面不能进行控制，可以创建也可以直接输入“n”跳过。设置好后杀掉创建出来的VNC进程：1vncserver -kill:1创建xstartup：1nano ~/.vnc/xstartup键入如下内容：123#!/bin/bashxrdb$HOME/.Xresourcesstartxfce4给这个文件加运行权限：1chmod +x ~/ ...继续阅读 (93)

记得一个脑筋急转弯，把一头大象装进冰箱需要几步？三步，打开冰箱，然后把大象装进去，关闭冰箱。我对于个人博客的搭建步骤也可以用三步来概括，注册域名、购买服务器、搭建博客，但当我们实际操作起来步骤远比想象的要多。今天写一篇从0到1的博客搭建教程，希望影响更多想写博客的人。防杠说明：我只以我的经验为基础，推荐和介绍我所用的服务器、程序，更好的方案有很多，不喜勿喷。并不是因为没有内容可写才出一篇搭建博客的教程，相反，我希望用这篇教程，让想写博客的人，可以写。基本概念在介绍博客如何搭建之前，有必要解释相关的概念。这里我采用初之音博客的解释，加以修改。访问我的博客，需要在浏览器里输入域名yinji.org，浏览器通过域名解析服务查询到上述网址指向的 IP 地址为 64.88.88.xx，IP 地址与服务器绑定，访问IP就是访问服务器。服务器查询到yinji.org指向的位置是 WordPress 博客程序所在的目录，因此返回该目录下所有可以展示的文件。最后，由博客程序将内容返回给访客，显示在浏览器上。因此，我们需要有域名、服务器、域名解析服务、IP、博客程序、运行环境。域名一个完整的域名有前缀和后缀，比如yinji.org，yinji是前缀，org是后缀，中间用符号.链接。所以我们在注册域名时，预先想好前缀，然后在可供选择的后缀中选择合适或者喜欢的。常见的后缀有.com、.net、.org、. ...继续阅读 (101)
