Alpine Linux 移植到

### 1.拉取并安装镜像
```c
docker pull arm32v7/alpine
```
```c
docker run -it --name armv7alpine --net=host -v /tmp/my-rootfs:/my-rootfs arm32v7/alpine
```
```c
docker run --rm --privileged multiarch/qemu-user-static --reset --persistent yes
```
### 2.镜像操作
```c
docker restart armv7alpine
```
```c
docker rm armv7alpine
```
```c
docker exec -it armv7alpine /bin/sh
```
### 3.环境配置及应用安装
##### 3.1安装基础服务
```c
apk add openrc
```
```c
rc-update add devfs boot
```
```c
rc-update add procfs boot
```
```c
rc-update add sysfs boot
```
```c
apk add openntpd
```
##### 3.2修改网络
```c
nano /etc/network/interfaces
```
```c
# /etc/network/interfaces.d/eth0
auto eth0
iface eth0 inet static
address 192.168.123.59
netmask 255.255.255.0
gateway 192.168.123.1
```
自动获取IP地址的网口配置
```
auto eth0
iface eth0 inet dhcp
```

##### 3.3修改DNS
- 
```c
nano /etc/resolv.conf
```
- 添加解析服务器
```c
nameserver 8.8.8.8
nameserver 8.8.4.4
```
- 重启网络服务
```c
/etc/init.d/networking restart
```
```c
rc-update add networking default
```

##### 3.4安装SSH服务
```c
apk add openssh
```
```c
rc-update add sshd default
```
```c
nano /etc/ssh/sshd_config
```
```c
# Authentication:
#LoginGraceTime 2m
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

#PubkeyAuthentication yes
# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication yes
```
##### 3.5自动校时
	nano /etc/ntp.conf  #新建校时服务器配置文件
代码如下
```
erver ntp.aliyun.com iburst
server ntp0.aliyun.com iburst
server ntp1.aliyun.com iburst
server ntp2.aliyun.com iburst
```
将自动校时添加到自启脚本
```
ntpd -d -q
```
##### 3.6时间自动同步

```c
apk add chrony
mkdir -p /var/run/chrony
chmod 0755 /var/run/chrony
/etc/init.d/chronyd start
```

### 4.目录文件操作
```c
rm -r /tmp/my-rootfs/*
```
```c
rm -r /home/ding/luckfox-pico/output/out/rootfs_uclibc_rv1106/
```
```c
rm -r /home/ding/luckfox-pico/sysdrv/custom_rootfs/*
```
```c
rm -r /home/ding/luckfox-pico/output/image/*
```
- 打包rootfs

```c
for d in bin etc lib root sbin usr; do tar c "$d" | tar x -C /my-rootfs; done
```
```c
for dir in dev proc run sys var; do mkdir /my-rootfs/${dir}; done
```
```c
cd /my-rootfs/ && tar czf alpine.tar.gz *
```
### 5.生成镜像
- 退出容器

```c
exit
```
```c
cp /tmp/my-rootfs/alpine.tar.gz /home/ding/luckfox-pico/sysdrv/custom_rootfs/
```
```c
/home/ding/luckfox-pico/project//build.sh
```

### 6.其他
- 安装内核
```c
apk add linux-lts
```
```c
cp /lib/modules/6.6.28-0-lts/kernel/drivers/net/tun.ko my-rootfs
```
```c
cp /tmp/my-rootfs/alpine.tar.gz /home/ding/luckfox-pico/sysdrv/custom_rootfs/
```
```c
./build.sh lunch
```
```c
./build.sh
```
 - 镜像源
```c
https://dl-cdn.alpinelinux.org/alpine/v3.17/main
https://dl-cdn.alpinelinux.org/alpine/v3.17/community
