首先，我本地的环境是 Mac + PHP 7.4.21 + Swoole Version => 4.6.7 + Composer version 2.4.4，作为学习，倡议大家对立抉择官网的 docker 镜像。
咱们先在本地创立一个目录，这个目录会间接映射到 hyperf 容器的 /data/project 目录。
~ » cd /data/work
/data/work » mkdir questions_learn执行上面的命令装置 hyperf 镜像，可能须要期待几分钟等待时间（如果本地没有这个镜像的话）。
docker run --name hyperf-php-8.0 \
-v /data/work/questions_learn:/data/project \
-p 9501:9501 -it \
--privileged -u root \
--entrypoint /bin/sh \
hyperf/hyperf:8.0-alpine-v3.15-swoole在这一步中，大家记得把 -v 前面的 “/data/work/questions_learn” 改成你本地的目录，其余的放弃不变。
下面的装置命令执行胜利后，咱们就曾经在 hyperf 容器内了，来一起看下 hyperf 容器内的环境。

......(省略了其余代码)
将 Composer 镜像设置为阿里云镜像，减速国内下载速度
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer能够看到，官网镜像默认反对了很多扩大，如果你抉择本人本地的环境，请至多确保你的运行环境达到了以下要求：
- PHP >= 8.0 and <= 8.1
- Swoole PHP 扩大 >= 4.5，并敞开了 Short Name
- JSON PHP 扩大
- Pcntl PHP 扩大
- enabled swoole coroutine、openssl、curl-native、async_redis、rwlock、pcre、zlib、brotl
另外，因为 Hyperf 基于 Swoole 协程实现，而 Swoole 4 带来的协程性能是 PHP 前所未有的，所以与不少扩大都仍存在兼容性的问题。
以下扩大（包含但不限于）都会造成肯定的兼容性问题，不能与之共用或共存：
- xhprof
- xdebug
- blackfire
- trace
- uopz
这些咱们根本也用不上，举荐大家依照文中的操作，抉择官网镜像。
上面咱们持续在容器内操作。
创立一个我的项目，并命名 questions
/ # cd /data/project/
/data/project # composer create-project hyperf/hyperf-skeleton questions执行 composer create-project 命令的时候，开始会始终提醒咱们装置一大堆货色，间接全副回车，前面须要咱们再手动进行装置。
装置好之后，装置的 hyperf 还是 2.2 版本，通过 composer info 命令能够查看已装置的 hyperf 相干的版本信息。
/data/project/questions # composer info | grep hyperf

接下来大家能够参考官网的降级指南，也能够跟着以后教程持续操作。
composer require hyperf/code-generator
php bin/hyperf.php code:generate -D app间接将 composer.json 中的 hyperf/ 对立批改为 3.0.，而后执行 composer update -o，当初咱们从新看下 hyperf 相干的版本信息。

启动我的项目测试下是否装置胜利

[DEBUG] Event Hyperf\Framework\Event\AfterWorkerStart handled by Hyperf\Server\Listener\InitProcessTitleListener listener.这里留神，更改过框架内的任何代码，都须要手动执行 php bin/hyperf.php start 命令，曾经启动的服务能够在终端按住 Ctrl + C 键进行服务。
本地咱们先依照这个模式走，前期上线会全自动操作，这点无需放心。
窗口卡着不动即示意装置胜利。
以上，咱们都是在容器内执行的命令操作。（将 composer.json 中的 hyperf/ 对立批改为 3.0.，这个大家能够在宿主机用 ide 进行编辑批改，编辑的是本地的 /data/work/questions_learn/questions/composer.json 文件）
回到宿主机内，对本地的 9501 端口申请测试。
/data/work » curl 127.0.0.1:9501
{"method":"GET","message":"Hello Hyperf."}%至此，hyperf 框架曾经装置结束。
教程中演示的所有代码，都会上传在 https://github.com/bailangzhan/questions_learn。
装置上如果有任何问题，能够在文章上面或者在 http://funqas.com/ 上发问留言。
