Docker 编译OpenHarmony 4.0 release

news 文章来源：https://blog.csdn.net/supernova_TOP/article/details/135149858 2024/9/22 11:29:05

一、背景介绍

1.1、环境配置

编译环境：Ubuntu 20.04
OpenHarmony版本：4.0 release
平台设备：RK3568

OpenHarmony 3.2更新至OpenHarmony 4.0后，公司服务器无法编译通过，总是在最后几十个文件时报错,错误码4000：

[OHOS ERROR] 3. repo sync
[OHOS ERROR] 4. repo forall -c 'git lfs pull'
[OHOS ERROR] 5. bash build/prebuilts_download.sh

[OHOS ERROR] 7. check if any environment variables required by the building process are not set in build/compile_env_allowlist.json
[OHOS ERROR]
[OHOS ERROR] If you still cannot solve this problem, you could post this problem on:

=====build error=====

经分析尝试：
1、相同的步骤和命令，wsl2 编译OpenHarmony 4.0 r正常。
2、服务器使用sudo编译正常，但由于sudo使用root权限，会影响项目编译链等配置，故不能作为解决方案。

于是尝试在服务器中使用docker，通过隔离环境编译OpenHarmony 4.0。

二、docker安装与配置

docker
在Ubuntu服务器中安装和配置docker

2.1、docker安装

$ sudo apt-get update
$ sudo apt-get upgrade$ sudo apt install docker.io
#安装后通过查看docker版本验证是否安装成功
$ docker --version 或 docker -v
Docker version 24.0.5, build 24.0.5-0ubuntu1~20.04.1

2.2、获取docker 镜像

获取docker镜像，以ubuntu:20.04为例
注意：此过程较漫长，请耐心等待~

$ docker pull ubuntu:20.04#创建好后可通过image命令查看
$ docker images 或docker image ls
REPOSITORY                                                               TAG       IMAGE ID       CREATED        SIZE
ubuntu                                                                   20.04     f78909c2b360   8 days ago     72.8MB
swr.cn-south-1.myhuaweicloud.com/openharmony-docker/docker_oh_standard   3.2       ae33c06f45c5   6 months ago   5.3GB

2.3、创建docker容器

#进入需要与docker映射的目录，后续基于此目录的修改，容器和服务会同步。
$ cd ~/docker/
$ docker run -it -v $(pwd):/home/zhangsan --name ohos ubuntu:20.04

说明：命令表示创建一个名为ohos，系统镜像为ubuntu 20.04的容器；这个容器运行在交互模式下，并且将当前目录映射到容器的/home/zhangsan目录。
注意：zhangsan需与后续要在ohos创建的非root用户名保持一致，否则后续下拉和编译代码会出现权限问题。

创建好ohos容器，默认以root用户进入。

#退出root用户
$ exit
# 启动ohos容器
$ docker container start ohos
#查看docker容器
$ docker container ls
CONTAINER ID   IMAGE          COMMAND       CREATED        STATUS        PORTS     NAMES
ab7d67807966   ubuntu:20.04   "/bin/bash"   29 hours ago   Up 29 hours             ohos

2.4、ohos容器中创建非root用户

由于docker 容易与宿主系统共享一个内核，容器中的用户ID和组ID是映射到宿主系统的；默认情况下，容器内的所有进程都以root用户身份运行。这意味着容器内的进程具有与宿主系统中的root用户相同的权限。为了提高安全性，建议在容器中使用非root用户运行进程。

#运行ohos容器（默认root用户）
$ docker exec -it ohos bash
$ apt-get update
$ apt-get upgrade
$ apt install -y sudo
$ apt install -y vim#添加非root用户zhangsan
$ useradd -m zhangsan
#设置用户密码，123456
$ passwd zhangsan
#设置zhangsan用户组
$ usermod -aG zhangsan zhangsan#sudoers添加zhangsan
$ vim /etc/sudoers	#文末添加一行zhangsan	ALL=(ALL)	ALL
#设置/home/zhangsan目录用户和组，需与用户名保持一致
$ chown -R zhangsan:zhangsan /home/zhangsan
$ exit

注意：zhangsan的uid和gid需与宿主系统自己的uid和gid保持一致，否则后续下载源码后，在宿主系统中自己无权限修改。
如下zhangsan 与wangwu的id匹配一致，为1003

#ohos容器zhangsan 用户名,uid,gid和组信息
$ whoami && id
uid=1003(zhangsan) gid=1003(zhangsan) groups=1003(zhangsan)#宿主系统自己账户（wangwu）用户名,uid,gid和组信息
$ whoami && id
wangwu
uid=1003(wangwu) gid=1003(wangwu) groups=1003(wangwu)

若ohos容器中zhangsan的uid与wangwu的不一致(通常zhangsan.uid < wangwu.uid）,可在容器中添加任意用户，uid号以1000开始累加，最终使得zhangsan.uid = wangwu.uid即可

#由于uid不匹配，先删除zhangsan用户
userdel zhangsan# 添加随意用户 tom,jerry
$ useradd -M tom
$ useradd -M jerry#查看所有用户
cat /etc/passwd
...
tom:x:1001:1001::/home/tom:/bin/sh
jerry:x:1002:1002::/home/jerry:/bin/sh#此时再次添加zhangsan用户，其uid则为1003

三、OpenHarmony 4.0 源码下载及编译

3.1、配置ohos容器编译环境

#以zhangsan用户运行ohos容器
$ docker exec --user zhangsan -it ohos bash#替换软件源
$ sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
$ sudo vim /etc/apt/sources.list	#sources.list替换以下内容

deb http://mirrors.ustc.edu.cn/ubuntu/ focal main restricted universe multiverse

更新
$ sudo apt-get update
$ sudo apt-get upgrade#将Shell环境修改为bash
$ sudo dpkg-reconfigure dash  #select no#部署编译环境，安装工具包
$ sudo apt-get install -y gcc-arm-linux-gnueabi gcc-9-arm-linux-gnueabi

#上一步命令执行过程需手动选择时区配置：6.Asia/70.Shanghai#配置pip软件包更新源
$ mkdir ~/.pip
$ pip3 config set global.index-url https://mirrors.huaweicloud.com/repository/pypi/simple
$ pip3 config set global.trusted-host mirrors.huaweicloud.com
$ pip3 config set global.timeout 120#配置git
git config --global user.email "jerry@163.com"
git config --global user.name "jerry"
git config --global credential.helper store
git config --global --add safe.directory "*"#安装repo
wget https://gitee.com/oschina/repo/raw/fork_flow/repo-py3
sudo mv repo-py3 /usr/local/bin/repo
sudo chmod a+x /usr/local/bin/repo
pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests

3.2、下拉OpenHarmony 4.0r源码及编译

$ mkdir OpenHarmony_4.0r && cd OpenHarmony_4.0r
$ repo init -u https://gitee.com/openharmony/manifest -b OpenHarmony-4.0-Release --no-repo-verify
$ repo sync -c && repo forall -c 'git lfs pull'
$ bash build/prebuilts_download.sh
$ ./build.sh -p rk3568	#编译成功，结果如下
...
Please modify according to README.md
[OHOS INFO] rk3568 build success

宿主系统可见openharmony 4.0r代码已拉下，并有权限修改

后续

当然，ohos环境可以自己打包成镜像推至自己的仓库，上述繁琐的过程可以在Dockerfile中进行配置，仅通过docker build 命令完成全部操作，刚接触docker,待后续优化完善~
