1 擴充套件安裝
安裝grpc、protobuf
2 Laravel專案安裝
2.1 指定倉庫地址
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
2.2 建立測試專案
composer create-project --prefer-dist laravel/laravel test-service "6.*"
2.3 引入依賴包
composer require alibaba/nacos
2.4 啟動服務
php artisan serve
php artisan serve --host 127.0.0.2 --port 8001
3 nacos服務安裝
3.1 選擇版本，進行安裝
本示例使用nacos-server-2.0.3版本
3.1.1 windows安裝
下載地址
https://github.com/alibaba/nacos/releases/download/2.0.3/nacos-server-2.0.3.zip
3.1.2 類Unix平臺安裝
wget https://github.com/alibaba/nacos/releases/download/2.0.3/nacos-server-2.0.3.tar.gz tar -xvf nacos-server-$version.tar.gz cd nacos/bin
3.2 啟動服務
3.2.1 類Unix平臺啟動
啟動命令(standalone代表著單機模式執行，非叢集模式):
sh startup.sh -m standalone
如果使用的是ubuntu系統，或者執行指令碼報錯提示[[符號找不到，可嘗試如下執行：
bash startup.sh -m standalone
3.2.2 Windows平臺啟動
啟動命令(standalone代表著單機模式執行，非叢集模式):
startup.cmd -m standalone
推薦使用下面方式更改startup.cmd檔案，指定單機模式,可以直接雙擊運。
set MODE="standalone"
3.3 nacos服務訪問
http://10.8.0.27:8848/nacos/index.html
初始賬號與密碼：nacos nacos
4 服務註冊、發現
4.1 例項註冊
curl -X POST 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=test-service&ip=127.0.0.1&port=8081'
通過App\Console\Commands\NacosRegisterInstance.php檔案進行註冊
<?php
namespace App\Console\Commands;
use alibaba\nacos\NacosConfig;
use alibaba\nacos\Naming;
use Illuminate\Console\Command;
class NacosRegisterInstance extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'nacos:register:instance';
/**
* The console command description.
*
* @var string
*/
protected $description = 'nacos:register:instance';
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
try {
NacosConfig::setHost("http://127.0.0.1:8848/"); // 配置中心地址
$naming = Naming::init(
"test-service",
"127.0.0.1",
"8081",
"",
"",
true
);
$naming->register();
} catch (\Exception $exception) {
}
}
}通過php artisan命令執行
php artisan nacos:register:instance
4.2 例項發現
curl -X GET 'http://127.0.0.1:8848/nacos/v1/ns/instance/list?serviceName=test-service'
通過App\Console\Commands\NacosGetInstance.php檔案進行例項發現
<?phpnamespace App\Console\Commands;use alibaba\nacos\NacosConfig;use alibaba\nacos\Naming;use alibaba\nacos\NamingClient;use Illuminate\Console\Command;class NacosGetInstance extends Command{ /** * The name and signature of the console command. * * @var string */ protected $signature = 'nacos:get:instance'; /** * The console command description. * * @var string */ protected $description = 'nacos:get:instance'; /** * Create a new command instance. * * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * * @return mixed */ public function handle() { try { NacosConfig::setHost("http://127.0.0.1:8848/"); // 配置中心地址 $naming = Naming::init( "test-service", "", "", "", "", true ); $instances = $naming->listInstances(true); if ($instances->getHosts()) { $hosts = []; foreach ($instances->getHosts() as $v) { $hosts[] = $v->getIp() . ":" . $v->getPort(); } var_dump($hosts); } else { throw new \Exception("未發現例項"); } } catch (\Exception $exception) { } }}
通過php artisan命令執行
php artisan nacos:get:instance
4.3 登出例項
curl -X DELETE 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=test-service&ip=127.0.0.1&port=8081'
通過App\Console\Commands\NacosDeleteInstance.php檔案進行例項發現
<?phpnamespace App\Console\Commands;use alibaba\nacos\NacosConfig;use alibaba\nacos\Naming;use alibaba\nacos\NamingClient;use alibaba\nacos\NamingConfig;use Illuminate\Console\Command;class NacosDeleteInstance extends Command{ /** * The name and signature of the console command. * * @var string */ protected $signature = 'nacos:delete:instance'; /** * The console command description. * * @var string */ protected $description = 'nacos:delete:instance'; /** * Create a new command instance. * * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * * @return mixed */ public function handle() { try { NacosConfig::setHost("http://127.0.0.1:8848/"); // 配置中心地址 $naming = Naming::init( "test-service", "127.0.0.1", "8081", "", "", true ); $response = $naming->delete(); } catch (\Exception $exception) { } }}4.3 修改例項
curl -X PUT '127.0.0.1:8848/nacos/v1/ns/instance?serviceName=test-service&ip=127.0.0.1&port=8081&clusterName=TEST1&weight=8&metadata={}'
通過App\Console\Commands\NacosUpdateInstance.php檔案進行例項發現
<?phpnamespace App\Console\Commands;use alibaba\nacos\NacosConfig;use alibaba\nacos\Naming;use alibaba\nacos\NamingClient;use alibaba\nacos\NamingConfig;use Illuminate\Console\Command;class NacosUpdateInstance extends Command{ /** * The name and signature of the console command. * * @var string */ protected $signature = 'nacos:update:instance'; /** * The console command description. * * @var string */ protected $description = 'nacos:update:instance'; /** * Create a new command instance. * * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * * @return mixed */ public function handle() { try { NacosConfig::setHost("http://127.0.0.1:8848/"); // 配置中心地址 $naming = Naming::init( "test-service", "127.0.0.1", "8081", "", "0", true ); $naming->update(); } catch (\Exception $exception) { } }}5 關閉伺服器
5.1 Linux/Unix/Mac
sh shutdown.sh
5.2 Windows
shutdown.cmd
或者雙擊shutdown.cmd執行檔案。
