官方简介
Raspberry Pi 4 是 Raspberry Pi 基金会推出的最新型微型服务器。这些微型服务器（或纳米计算机）最初是为技术爱好者设计的利基产品，其目的是使电子产品更具吸引力且价格适中，其后迅速获得成功，如今成为真正的经典产品。价格合理，体积小巧，用户使用一台微型计算机就可以整合许多项目，无论是媒体中心这样的个人项目，还是网站托管、应用程序托管等专业项目，甚至还可用于远程备份。
在功能方面，这款全新的 Raspberry Pi 4 极具吸引力，其处理器速度比以前的版本快得多，带有千兆端口、USB3 接口，还可安装多达 4 GB 的运行内存 RAM。
配置
正好自己这个月买了一台树莓派4B，ikoula家这个月也是测评这款机器。
这款树莓派的配置如下：
CPU是@1,5GHz ARM v8架构的处理器。默认给的是ipv6地址，ipv4为可选项目。内存为4 GB DDR4。存储可选16 GB SD Card 或 120 GB SSD，给我的测评机器为16 GB的SD Card。带宽也是很实在的给到了1 Gbit/s。
如果看了文章对这款RASPBERRY PI 4有兴趣的朋友，可以点击以下链接选购：
ssh连接
因为默认给的是ipv6的地址，所以我们连接服务器的时候需要我们本地支持ipv6.
如果本地支持ipv6的话，那么我们直接连接就可以了，如果像我一样，本地没有ipv6，那就需要找一些办法了。其中最简单的办法就是手机开启热点，然后电脑连接手机的热点，因为手机的流量是自带ipv6的，所以我们用电脑连接手机热点就可以支持ipv6了。
更改dns64使ipv6访问ipv4资源
首先编辑/etc/resolv.conf，删除现有的nameserver，添加以下nameserver。这是为了能访问v4地址。
nameserver 2001:67c:2b0::4
nameserver 2001:67c:2b0::6bench.sh

I/O Speed(3rd run) : 19.0 MB/s
Average I/O speed : 14.4 MB/s
----------------------------------------------------------------------虽然是SD卡，但这个io还是有点低啊。
接下来我们换个测试的工具试一试
hdparm测试硬盘读性能
安装hdparm
sudo apt-get install hdparm
测试存储缓存和存储的读取速度：
root@frhb53059ds:~# hdparm -Tt /dev/mmcblk0
/dev/mmcblk0:
Timing cached reads: 1702 MB in 2.00 seconds = 851.65 MB/sec
HDIO_DRIVE_CMD(identify) failed: Invalid argument
Timing buffered disk reads: 130 MB in 3.00 seconds = 43.33 MB/sec直接测试存储的读性能
root@frhb53059ds:~# hdparm -Tt --direct /dev/mmcblk0
/dev/mmcblk0:
Timing O_DIRECT cached reads: 82 MB in 2.03 seconds = 40.48 MB/sec
HDIO_DRIVE_CMD(identify) failed: Invalid argument
Timing O_DIRECT disk reads: 122 MB in 3.02 seconds = 40.39 MB/sec这里可以看到io其实并没有前面测试的那么低，但是也不是很高，对于一张SD的卡来说，只能算是中规中矩。
因为我测试的只是带SD卡的，SSD硬盘的我也没有办法测试。

System Benchmarks Index Score 866.5开启远程桌面VNC
树莓派和别的vps一个不同的地方就在于，树莓派可以开启内置的远程桌面，我们就可以像控制自己的电脑一样快乐的玩耍了。
我们在ssh连接上树莓派后，输入apt-get update更新一下。
然后给树莓派安装桌面服务
<code>sudo apt install xrdp启动自带的配置程序：
sudo raspi-config 启动后界面如下：
选择5 Interfacing Options Configure connections to peripherals
然后选择P3 VNC Enable/Disable graphicaL remote access to your Pi using ReaLVNC
yes后会来到ssh界面，选择y，一路看着屏幕上的命令跑下去即可。最后按ESC退出配置界面。
更改桌面默认分辨率
当在没有把树莓派连接到任何视频设备(电视或者显示屏)时候就会执行默认分辨率，而这个分辨率是VNC不支持的，所以会出现问题，报错cannot currently show the desktop。
解决办法如下：
ssh输入sudo raspi-config进入树莓派设置界面，选择第7项 Advanced Options : Configure advanced settings
接着选择第5项 A5 Resolution : Set a specific screen resolution
接着选择一个新的分辨率，比如 DMT Mode 82 1920×1080 60Hz 16:9
配置完后选择finish，然后reboot即可。注意，最后一步重启很重要，不要忽略。
安装 VNC Viewer
单启动树莓派 VNC 服务器还不够，还要在电脑上安装 VNC Viewer 客户端，才能连接树莓派远程桌面。
进入官网下载客户端：https://www.realvnc.com/en/connect/download/viewer/
要注意的是，我们现在安装的是 VNC Viewer 客户端，是装在电脑上的，所以选下面截图红框部分的版本就行，不要选到树莓派版本。
连接远程桌面
上述操作都完成后，可以开始连接远程桌面了。
在电脑上启动 VNC Viewer，点击左上角的“新建连接”菜单，填入树莓派的 ip 地址，点击“确定”。
接着，双击刚刚创建出来的连接，VNC Viewer 会弹窗让你输入树莓派的用户名和密码。输入后点确定。
如果连接后显示cannot currently show the desktop,那可能是树莓派内存空间不够用了，无法调出桌面
这里我遇到了这个问题，参考了以下博文：https://blog.csdn.net/m0_46339652/article/details/107314197
