Hyperf概述

尽管现在基于PHP语言开发的框架处于一个百家争鸣的时代，但仍旧未能看到一个优雅的设计与超高性能的共存的完美框架，亦没有看到一个真正为PHP微服务铺路的框架，此为Hyperf及其团队成员的初衷。

Hyperf是一个高性能、高灵活性的渐进式PHP协程框架，内置协程服务器及大量常用的组件，性能较传统基于PHP-FPM的框架有质的提升，提供超高性能的同时，也保持着极其灵活的可扩展性，标准组件均基于PSR标准实现和强大的依赖注入设计，保证了绝大部分组件或类都是可替换与可复用的。

Hyperspeed + Flexibility = Hyperf，从名字上就可以看出超高速和灵活性是Hyperf的基因。对于超高速，Hyperf基于Swoole和Swow协程，并在框架设计上进行大量的优化以确保超高性能的输出。对于灵活性，Hyperf强大的依赖注入组件，组件均基于PSR标准的契约和由Hyperf定义的契约实现，达到框架内的绝大部分的组件或类都是可替换的。

Hyperf运行环境如下：

• Linux
• PHP 8.0+
• Swoole 4.5+ or Swow

基础准备

下载软件包至本地：

[root@master ~]# ls
Hyperf.tar.gz

解压软件包并导入镜像：

[root@master ~]# tar -zxf Hyperf.tar.gz
[root@master ~]# docker load -i Hyperf/images/centos_7.9.2009.tar

安装Docker Compose：

[root@master ~]# cp Hyperf/docker-compose-Linux-x86_64 /usr/bin/docker-compose
[root@master ~]# docker-compose version
docker-compose version 1.25.0, build 0a186604
docker-py version: 4.1.0
CPython version: 3.7.4
OpenSSL version: OpenSSL 1.1.0l 10 Sep 2019

容器化部署MySQL

（1）编写Dockerfile

编写init.sh脚本：

[root@master ~]# cd Hyperf/
[root@master Hyperf]# vi mysql_init.sh 
#!/bin/bash
mysql_install_db --user=root
mysqld_safe --user=root &
sleep 8
mysqladmin -u root password 'root'
mysql -uroot -proot -e "grant all on *.* to 'root'@'%' identified by 'root'; flush privileges;"
mysql -uroot -proot -e " source /opt/hyperf_admin.sql;"

编写yum源：

[root@master Hyperf]# vi local.repo 
[hyperf]
name=hyperf
baseurl=file:///root/yum
gpgcheck=0
enabled=1

编写Dockerfile文件：

[root@master Hyperf]# vi Dockerfile-mysql 
FROM centos:7.9.2009
MAINTAINER Chinaskills
RUN rm -rf /etc/yum.repos.d/*
COPY local.repo /etc/yum.repos.d/
COPY yum /root/yum
ENV LC_ALL en_US.UTF-8
RUN yum -y install mariadb-server
COPY sql /opt/
COPY mysql_init.sh /opt/
RUN bash /opt/mysql_init.sh
EXPOSE 3306
CMD ["mysqld_safe","--user=root"]

（2）构建镜像

[root@master Hyperf]# docker build -t hyperf-mysql:v1.0 -f Dockerfile-mysql .

[root@master Hyperf]# vi project/docker-compose.yaml
version: '3.1'
services:
  app:
    container_name: hyperf-admin
    image: hyperf-admin:v1.0
    command:
      - /bin/sh
      - -c
      - |
        cd /data
        cp .env.dev.docker .env
        php -d memory_limit=-1 `which composer` i --no-dev
        rm -rf runtime/*
        php bin/hyperf.php start
    volumes:
      - ./backend:/data
    tty: true
    links:
      - mysql
      - redis
    environment:
      HOST_IP: 127.0.0.1
      HOST_PORT: 9511
  mysql:
    container_name: mysql
    image: hyperf-mysql:v1.0
    ports:
      - 3307:3306
    environment:
      TZ: Asia/Shanghai
    volumes:
      - ./docker/data:/var/lib/mysql:rw
  redis:
    image: hyperf-redis:v1.0
    container_name: redis
#    command: redis-server
  nginx:
    image: hyperf-nginx:v1.0
    container_name: nginx
    ports:
      - 8081:80
    links:
      - app
    volumes:
      - ./docker/conf.d:/etc/nginx/conf.d
      - ./docker/log:/var/log/nginx
      - ./frontend:/var/www/frontend

（2）部署服务

[root@master Hyperf]# docker-compose -f project/docker-compose.yaml up -d
Creating network "project_default" with the default driver
Creating mysql ... done
Creating redis ... done
Creating hyperf-admin ... done
Creating nginx        ... done

查看服务：

[root@master Hyperf]# docker-compose -f project/docker-compose.yaml ps
Name                  Command                 State           Ports
