第四季 NOOBS | Raspberry pi，一个好玩的派

今天换个玩法，不继续深入探索Raspbian系统了，研究一下官网推荐的另一种安装方法NOOBS。那么什么是NOOBS呢？它是专为Raspberry pi打造的简单易用的图形界面的操作系统管理工具。全称为：**New Out Of the Box Software** 官方截图如下： ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-05_568b30865626d.jpg) 本工具的初衷就是简化Raspberry pi安装系统的繁琐，因为Raspberry pi的板子买来是不带系统的，我们需要额外购买SDCard来安装系统。对很多新手来说，命令行的东西肯定是没有图形界面来得简单易懂。正是由于每个sdcard上面代表着安装好的系统，我们可以通过多买几个sdcard就可以持续性的体验不同的系统，只需通过换个sdcard搞定，真是特别方便。下面来说说我是如果在另一张8G卡用NOOBS安装系统Raspbian的。 #### 第一步，下载NOOBS [官网链接](http://www.raspberrypi.org/downloads)，记得自己是在Ubuntu下用Firefox浏览器下载的，可以断点续传。 #### 第二步，格式化SDCard 如果你的SDCard本来就是FAT32文件系统，那么跳过这一步。不要被这一步吓到，如果不用格式化，那么NOOBS安装只需要三步：**下载**、**解压**、在Raspberry pi上**启动**。 Linux下将SDCard格式化成Fat32文件系统。用fdisk命令，需要root权限，或者sudo。插上SDCard卡，执行如下命令： ~~~ #fdisk -l Disk /dev/sdb: 8054 MB, 8054112256 bytes 49 heads, 29 sectors/track, 11070 cylinders, total 15730688 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 8192 15730687 7861248 b W95 FAT32 ~~~ 看来我的8G卡现在已经是FAT32系统了，而且就这一个分区。不要紧，过程我还是要执行一遍。 ~~~ #fdisk /dev/sdb1 Command (m for help): d No partition is defined yet! Command (m for help): p Disk /dev/sdb1: 8049 MB, 8049917952 bytes 248 heads, 62 sectors/track, 1022 cylinders, total 15722496 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System 1 Command (m for help): n Partition type: p primary (0 primary, 0 extended, 4 free) e extended Select (default p): p Partition number (1-4, default 1): 1 First sector (2048-15722495, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-15722495, default 15722495): Using default value 15722495 ~~~ Tips：回车（Enter）键选择默认项。 Tips:Enter is means you select default option. 上面创建了一个主分区，1号分区。并且设置了启动和结束的扇区值。我们再来看看创建的情况： ~~~ Command (m for help): p Disk /dev/sdb1: 8049 MB, 8049917952 bytes 248 heads, 62 sectors/track, 1022 cylinders, total 15722496 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1p1 2048 15722495 7860224 83 Linux ~~~ 好的，我们的分区类型是linux，下面我们再把它转换成FAT32. ~~~ Command (m for help): t Selected partition 1 Hex code (type L to list codes): l //attention!This is L!

Calling ioctl() to re-read partition table. WARNING: Re-reading the partition table failed with error 22: Invalid argument. The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8) WARNING: If you have created or modified any DOS 6.x partitions, please see the fdisk manual page for additional information. Syncing disks. mkfs.vfat /dev/sdb1 mkfs.vfat 3.0.12 (29 Oct 2011) mkfs.vfat: /dev/sdb1 contains a mounted file system. ~~~ 值得注意的是，我上面的format操作貌似没有成功。因为在sdcard中还可以看到原有文件，也许是因为写保护？还是什么别的原因？好像我的一系列操作都没有成功似的。 #### 第三步，将NOOBS文件解压到SDCard 如果SDCard本来就是FAT32系统，那么直接就可以做这一步，这也就是用NOOBS工具安装系统的方便之所在。解压过程：此时我在sdcard的目录下，直接执行unzip。 ~~~ unzip ~/raspberrypi/NOOBS_v1_3_10.zip Archive: ~/raspberrypi/NOOBS_v1_3_10.zip inflating: BUILD-DATA inflating: INSTRUCTIONS-README.txt extracting: RECOVERY_FILES_DO_NOT_EDIT inflating: bootcode.bin creating: defaults/ creating: defaults/slides/ inflating: defaults/slides/A.png creating: os/ creating: os/Raspbian/ inflating: os/Raspbian/root.tar.xz inflating: os/Raspbian/boot.tar.xz inflating: os/Raspbian/partition_setup.sh extracting: os/Raspbian/Raspbian.png creating: os/Raspbian/slides_vga/ inflating: os/Raspbian/slides_vga/G.png inflating: os/Raspbian/slides_vga/B.png inflating: os/Raspbian/slides_vga/C.png inflating: os/Raspbian/slides_vga/D.png inflating: os/Raspbian/slides_vga/E.png inflating: os/Raspbian/slides_vga/F.png inflating: os/Raspbian/slides_vga/A.png inflating: os/Raspbian/partitions.json inflating: os/Raspbian/flavours.json extracting: os/Raspbian/Raspbian_-_Boot_to_Scratch.png inflating: os/Raspbian/os.json inflating: os/Raspbian/release_notes.txt creating: os/Data_Partition/ extracting: os/Data_Partition/Data_Partition.png inflating: os/Data_Partition/partitions.json inflating: os/Data_Partition/os.json extracting: os/Data_Partition/data.tar.xz inflating: recovery.cmdline inflating: recovery.elf inflating: recovery.img inflating: recovery.rfs inflating: riscos-boot.bin ~~~ #### 第四步，启动现在可以把SDCard从电脑上退下来，插到板子上，加电启动。如下图所示： ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-05_568b30866b5f8.jpg) ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-05_568b30868472c.jpg) ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-05_568b30869f3b7.jpg) ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-05_568b3086c2f46.jpg) 在安装中，拷贝速度是1.4MB/s,明显比直接用dd命令将img拷贝到sdcard中慢。经过漫长的安装过程，终于成功了。启动画面与上一季完全一样。 ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-05_568b3086e4128.jpg) 参考：官方安装文档：http://www.raspberrypi.org/documentation/installation/noobs.md
