# 在树莓派4B上安装CentOS
|
||
|
||
## 烧录镜像
|
||
|
||
* 从华为镜像服务下载 RaspberryPI 的 CentOS 镜像，下载地址为：
|
||
|
||
http://mirrors.huaweicloud.com/centos-altarch/7.7.1908/isos/armhfp/CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-1908-sda.raw.xz
|
||
|
||
* 从 raspberrypi 下载镜像烧录工具 Raspberry Pi Imager
|
||
|
||
https://www.raspberrypi.org/downloads/
|
||
|
||
* 将 raspberrypi 连接到路由器（有线）
|
||
* ssh 登录，默认密码为 centos
|
||
|
||
## 扩展磁盘
|
||
|
||
* 执行 `df -h` 可以看到，系统只有 2G 的存储空间，TF 卡上的剩余空间未被利用
|
||
|
||
* 在 /root 目录下执行：
|
||
```sh
|
||
cat README
|
||
```
|
||
结果为
|
||
```
|
||
== CentOS 7 userland ==
|
||
|
||
If you want to automatically resize your / partition, just type the following (as root user):
|
||
rootfs-expand
|
||
```
|
||
* echo $LANG，如果结果为 `zh_CN.UTF-8`，执行 rootfs-expand 命令将失败
|
||
* 执行命令
|
||
``` sh
|
||
export LANG="en_US.UTF-8"
|
||
```
|
||
* 执行命令
|
||
``` sh
|
||
rootfs-expand
|
||
```
|
||
执行成功
|
||
* 查看磁盘情况
|
||
``` sh
|
||
[root@localhost ~]# df -h
|
||

|
||
tmpfs 2.0G 0 2.0G 0% /dev/shm
|
||

||
```
|
||
|
||
## 修改 hostname
|
||
|
||
```sh
|
||
# 修改 hostname
|
||
hostnamectl set-hostname your-new-host-name
|
||
# 查看修改结果
|
||
hostnamectl status
|
||
# 设置 hostname 解析
|
||
echo "127.0.0.1 $(hostname)" >> /etc/hosts
|
||
```
|
||
|
||
## 设置国内yum镜像源
|
||
|
||
建议使用 [华为开源镜像站](https://mirrors.huaweicloud.com/)
|
||
|
||
选择 `CentOS-AltArch` 按照其提供的步骤设置 yum 镜像源。
|
||
|
||
|
||
## 安装 Docker
|
||
|
||
```sh
|
||
yum install docker
|
||
```
|
||
|
||
## 安装 nodejs
|
||
|
||
必须下载源代码编译
|
||
|
||
* 以 `root` 用户登录系统
|
||
|
||
* 安装编译工具
|
||
``` sh
|
||
yum install -y gcc gcc-c++ make
|
||
```
|
||
|
||
* 下载源代码并编译
|
||
``` sh
|
||
wget https://npm.taobao.org/mirrors/node/v12.16.1/node-v12.16.1.tar.gz
|
||
tar -xvf node-v12.16.1.tar.gz
|
||
cd node-v12.16.1
|
||
./configure
|
||
make
|
||
make install
|
||
```
|
||
* 重启
|
||
```sh
|
||
reboot
