一、背景介紹
1.1、環(huán)境配置
- 編譯環(huán)境：Ubuntu 20.04
- OpenHarmony版本：4.0 release
- 平臺(tái)設(shè)備：RK3568
OpenHarmony 3.2更新至OpenHarmony 4.0后，公司服務(wù)器無法編譯通過，總是在最后幾十個(gè)文件時(shí)報(bào)錯(cuò),錯(cuò)誤碼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] 6. rebuild your product or component
[OHOS ERROR] 7. check if any environment variables required by the building process are not set in build/compile_env_allowlist.json

=====build error=====
經(jīng)分析嘗試：
1、相同的步驟和命令，wsl2 編譯OpenHarmony 4.0 r正常。
2、服務(wù)器使用sudo編譯正常，但由于sudo使用root權(quán)限，會(huì)影響項(xiàng)目編譯鏈等配置，故不能作為解決方案。
于是嘗試在服務(wù)器中使用docker，通過隔離環(huán)境編譯OpenHarmony 4.0。
二、docker安裝與配置
在Ubuntu服務(wù)器中安裝和配置docker
2.1、docker安裝
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt install docker.io
#安裝后通過查看docker版本驗(yàn)證是否安裝成功
$ docker --version 或 docker -v
Docker version 24.0.5, build 24.0.5-0ubuntu1~20.04.1
2.2、獲取docker 鏡像
獲取docker鏡像，以u(píng)buntu:20.04為例注意：此過程較漫長(zhǎng)，請(qǐng)耐心等待~
$ docker pull ubuntu:20.04
#創(chuàng)建好后可通過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、創(chuàng)建docker容器
#進(jìn)入需要與docker映射的目錄，后續(xù)基于此目錄的修改，容器和服務(wù)會(huì)同步。
$ cd ~/docker/
$ docker run -it -v $(pwd):/home/zhangsan --name ohos ubuntu:20.04
說明：命令表示創(chuàng)建一個(gè)名為ohos，系統(tǒng)鏡像為ubuntu 20.04的容器；這個(gè)容器運(yùn)行在交互模式下，并且將當(dāng)前目錄映射到容器的/home/zhangsan目錄。注意：zhangsan需與后續(xù)要在ohos創(chuàng)建的非root用戶名保持一致，否則后續(xù)下拉和編譯代碼會(huì)出現(xiàn)權(quán)限問題。
創(chuàng)建好ohos容器，默認(rèn)以root用戶進(jìn)入。
#退出root用戶
$ exit
# 啟動(dòng)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容器中創(chuàng)建非root用戶
由于docker 容易與宿主系統(tǒng)共享一個(gè)內(nèi)核，容器中的用戶ID和組ID是映射到宿主系統(tǒng)的；默認(rèn)情況下，容器內(nèi)的所有進(jìn)程都以root用戶身份運(yùn)行。這意味著容器內(nèi)的進(jìn)程具有與宿主系統(tǒng)中的root用戶相同的權(quán)限。為了提高安全性，建議在容器中使用非root用戶運(yùn)行進(jìn)程。
#運(yùn)行ohos容器（默認(rèn)root用戶）
$ docker exec -it ohos bash
$ apt-get update
$ apt-get upgrade
$ apt install -y sudo
$ apt install -y vim
#添加非root用戶zhangsan
$ useradd -m zhangsan
#設(shè)置用戶密碼，123456
$ passwd zhangsan
#設(shè)置zhangsan用戶組
$ usermod -aG zhangsan zhangsan
#sudoers添加zhangsan
$ vim /etc/sudoers #文末添加一行zhangsan ALL=(ALL) ALL
#設(shè)置/home/zhangsan目錄用戶和組，需與用戶名保持一致
$ chown -R zhangsan:zhangsan /home/zhangsan
$ exit
注意：zhangsan的uid和gid需與宿主系統(tǒng)自己的uid和gid保持一致，否則后續(xù)下載源碼后，在宿主系統(tǒng)中自己無權(quán)限修改。
如下zhangsan 與wangwu的id匹配一致，為1003
#ohos容器zhangsan 用戶名,uid,gid和組信息
$ whoami && id
uid=1003(zhangsan) gid=1003(zhangsan) groups=1003(zhangsan)
#宿主系統(tǒng)自己賬戶（wangwu）用戶名,uid,gid和組信息
$ whoami && id
wangwu
uid=1003(wangwu) gid=1003(wangwu) groups=1003(wangwu)
若ohos容器中zhangsan的uid與wangwu的不一致(通常zhangsan.uid < wangwu.uid）,可在容器中添加任意用戶，uid號(hào)以1000開始累加，最終使得zhangsan.uid = wangwu.uid即可
#由于uid不匹配，先刪除zhangsan用戶
userdel zhangsan
# 添加隨意用戶 tom,jerry
$ useradd -M tom
$ useradd -M jerry
#查看所有用戶
cat /etc/passwd
...
tom:x:1001:1001::/home/tom:/bin/sh
jerry:x:1002:1002::/home/jerry:/bin/sh
#此時(shí)再次添加zhangsan用戶，其uid則為1003
三、OpenHarmony 4.0 源碼下載及編譯
3.1、配置ohos容器編譯環(huán)境
#以zhangsan用戶運(yùn)行ohos容器
$ docker exec --user zhangsan -it ohos bash
#替換軟件源
$ sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
$ sudo vim /etc/apt/sources.list #sources.list替換以下內(nèi)容

$ 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'
