Install CentOS 7 arm on raspberry pi 3 (raspberry pi 3)

Raspberry Pi 3 already supports Bluetooth and built-in wireless NICs by default. The price is only $35. I was lucky enough to have a copy of X Package. I also used Raspberry Pi for the first time. Because Raspberry Pi 3 was just launched soon, there are few tutorials on the internet. Let's share with you how Raspberry Pi 3 installed centos 7 arm.

I. Prepare tools

A tf card larger than 4G capacity (please back up important data)

Centos 7 image, which can be downloaded from the official address

Win32DiskImager, download address: pan.baidu.com/s/1bp2pZFx

II. Write to system

Decompress the downloaded image from the official website through the compression software (such as WinRAR or 7-zip) to obtain the CentOS-Userland-7-armv7hl-Minimal-1603-RaspberryPi3.img.xz file, as shown in the following screenshot.
Open the software Win32DiskImager, select the decompressed image file according to the following screenshot, select the drive letter of the TF card, and click write to the system. Wait until the write is completed.

III. Remote connection

Connect the Raspberry Pi network cable, install the TF card, turn on the power, and then automatically initialize the system and networking. When the Raspberry Pi indicator light shows red, it indicates that it is successful, we can view and record the IP addresses assigned to Raspberry Pi through the vro. Then use the SSH tool to connect. (Default account: root, password: centos)
In addition, the memory card is re-partitioned after being written into the system, resulting in a large amount of waste of idle partitions. You need to enter the following command to re-allocate idle partitions.

Touch/. rootfs-repartition
Systemctl reboot

Finally, you can use yum and other software to install it. However, the official yum source of centos 7 arm seems to be relatively small, and many software cannot be installed. I don't want to recommend installing the Raspberry Pi official system: RASPBIAN.
