Hyperf微服务搭建
一、安装 consul 服务
docker pull consul
docker run --name=consul -p 8500:8500 -e CONSUL_BIND_INTERFACE=eth0 -d consul 
安装并启动成功后访问：http://本机IP:8500/
二、服务提供者
2.1、启动服务提供者容器
// 本地 D:\phpstudy_pro\WWW 目录创建一个 hyperf 项目作为服务提供者
composer create-project hyperf/hyperf-skeleton hyperf-db
// 基于hyperf镜像生成容器
docker run --name hyperf -v D:\phpstudy_pro\WWW\hyperf-db:/data/project/hyperf-db -p 9501:9501 -it --privileged -u root --entrypoint /bin/sh hyperf/hyperf:7.4-alpine-v3.11-swoole
cd data/project/hyperf-db
// 安装统一接入层
composer require hyperf/service-governance
// 选择安装对应的适配器（这里用consul）
composer require hyperf/service-governance-consul
composer require hyperf/service-governance-nacos
// 安装 JSON RPC 服务
composer require hyperf/json-rpc
// 安装 JSON RPC 服务端
composer require hyperf/rpc-server
// 安装 JSON RPC 客户端
composer require hyperf/rpc-client
// 安装 consul 组件
composer require hyperf/consul
// 发布 consul 组件配置到 app
php bin/hyperf.php vendor:publish hyperf/consul2.2、定义 JSON RPC Server
'servers' => [
[
'name' => 'http',
'type' => Server::SERVER_HTTP,
'host' => '0.0.0.0',
'port' => 9501,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
Event::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
],
],
[
'name' => 'jsonrpc-http',
'type' => Server::SERVER_HTTP,
'host' => '0.0.0.0',
'port' => 9504,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
Event::ON_REQUEST => [\Hyperf\JsonRpc\HttpServer::class, 'onRequest'],
],
],
[
'name' => 'jsonrpc',
'type' => Server::SERVER_BASE,
'host' => '0.0.0.0',
'port' => 9503,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
Event::ON_RECEIVE => [\Hyperf\JsonRpc\TcpServer::class, 'onReceive'],
],
'settings' => [
'open_length_check' => true,
'package_length_type' => 'N',
'package_length_offset' => 0,
'package_body_offset' => 4,
'package_max_length' => 1024 * 1024 * 2,
],
],
],2.3、定义接口
2.4、定义服务提供者
2.5、发布到服务中心
在 config/autoload/services.php 配置文件内配置 drivers.consul 配置即可，注意 127.0.0.1 需要更换本机 ip 地址，否则会报错。
return [
'enable' => [
'discovery' => true,
'register' => true,
],
'providers' => [],
'drivers' => [
'consul' => [
'uri' => 'http://127.0.0.1:8500',
'token' => '',
'check' => [
'deregister_critical_service_after' => '90m',
'interval' => '1s',
],
],
'nacos' => [
// nacos server url like https://nacos.hyperf.io, Priority is higher than host:port
// 'url' => '',
// The nacos host info
'host' => '127.0.0.1',
'port' => 8848,
// The nacos account info
'username' => null,
'password' => null,
'guzzle' => [
'config' => null,
],
'group_name' => 'api',
'namespace_id' => 'namespace_id',
'heartbeat' => 5,
'ephemeral' => false,
],
],
];三、服务消费者
3.1、启动服务消费者容器
// 本地 D:\phpstudy_pro\WWW 目录创建一个 hyperf 项目作为服务消费者
composer create-project hyperf/hyperf-skeleton hyperf-api
// 基于hyperf镜像生成容器
docker run --name hyperf-api -v D:\phpstudy_pro\WWW\hyperf-api:/data/project/hyperf-api -p 9502:9502 -it --privileged -u root --entrypoint /bin/sh hyperf/hyperf:7.4-alpine-v3.11-swoole
cd data/project/hyperf-api服务消费者也可以作为服务提供者提供服务，所以按照之前的步骤把相关组件安装一下
3.2、修改 server 配置
// config/autoload/server.php
'servers' => [
[
'name' => 'http',
'type' => Server::SERVER_HTTP,
'host' => '0.0.0.0',
'port' => 9502,
'sock_type' => SWOOLE_SOCK_TCP,
'callbacks' => [
Event::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
],
],
],
// config/autoload/services.php
'consumers' => [
[
// name 需与服务提供者的 name 属性相同
'name' => 'CalculatorService',
// 服务接口名，可选，默认值等于 name 配置的值，如果 name 直接定义为接口类则可忽略此行配置，如 name 为字符串则需要配置 service 对应到接口类
'service' => \App\JsonRpc\CalculatorServiceInterface::class,
// 对应容器对象 ID，可选，默认值等于 service 配置的值，用来定义依赖注入的 key
'id' => \App\JsonRpc\CalculatorServiceInterface::class,
// 服务提供者的服务协议，可选，默认值为 jsonrpc-http
// 可选 jsonrpc-http jsonrpc jsonrpc-tcp-length-check
'protocol' => 'jsonrpc-http',
// 负载均衡算法，可选，默认值为 random
'load_balancer' => 'random',
// 这个消费者要从哪个服务中心获取节点信息，如不配置则不会从服务中心获取节点信息
'registry' => [
'protocol' => 'consul',
'address' => 'http://127.0.0.1:8500',
],
// 如果没有指定上面的 registry 配置，即为直接对指定的节点进行消费，通过下面的 nodes 参数来配置服务提供者的节点信息
'nodes' => [
['host' => '127.0.0.1', 'port' => 9504],
],
// 配置项，会影响到 Packer 和 Transporter
'options' => [
'connect_timeout' => 5.0,
'recv_timeout' => 5.0,
'settings' => [
// 根据协议不同，区分配置
'open_eof_split' => true,
'package_eof' => "\r\n",
// 'open_length_check' => true,
// 'package_length_type' => 'N',
// 'package_length_offset' => 0,
// 'package_body_offset' => 4,
],
// 重试次数，默认值为 2，收包超时不进行重试。暂只支持 JsonRpcPoolTransporter
'retry_count' => 2,
// 重试间隔，毫秒
'retry_interval' => 100,
// 使用多路复用 RPC 时的心跳间隔，null 为不触发心跳
'heartbeat' => 30,
// 当使用 JsonRpcPoolTransporter 时会用到以下配置
'pool' => [
'min_connections' => 1,
'max_connections' => 32,
'connect_timeout' => 10.0,
'wait_timeout' => 3.0,
'heartbeat' => -1,
'max_idle_time' => 60.0,
],
],
]
],
'drivers' => [
'consul' => [
'uri' => 'http://127.0.0.1:8500',
'token' => '',
'check' => [
'deregister_critical_service_after' => '90m',
'interval' => '1s',
],
],
'nacos' => [
// nacos server url like https://nacos.hyperf.io, Priority is higher than host:port
// 'url' => '',
// The nacos host info
'host' => '127.0.0.1',
'port' => 8848,
// The nacos account info
'username' => null,
'password' => null,
'guzzle' => [
'config' => null,
],
'group_name' => 'api',
'namespace_id' => 'namespace_id',
'heartbeat' => 5,
'ephemeral' => false,
],
],3.3、定义接口，同服务端保持一致
3.4、定义路由
Router::get('/testRpc', 'App\Controller\IndexController::testRpc');3.5、控制器中调用
public function testRpc()
{
$client = ApplicationContext::getContainer()->get(CalculatorServiceInterface::class);
$res = $client->add(1,2);
return ['result'=>$res];
}
