环境准备：
| 插件 | 版本 |
| jdk | 21 |
| springboot | 3.0.11 |
| springcloud | 2022.0.4 |
| springcloudalibaba | 2022.0.0.0 |
| nacos | 2.2.3（稳定版） |
| python | 3.8 |
nacos部署（docker）
先创建目录，分别创建config，logs，data目录，单独创建一个容器
docker run -d \
-e MODE=standalone \
-p 8848:8848 \
-p 9848:9848 \
-p 7848:7848 \
-v /data/nacos/conf:/mnt/data3/dockerfiles/nacos/config \
-v /data/nacos/logs:/mnt/data3/dockerfiles/nacos/logs \
-v /data/nacos/data:/mnt/data3/dockerfiles/nacos/data \
--name nacos-mysql \
--restart=always \
nacos/nacos-server:v2.2.3将配置文件拷贝出来(主要是application.properties和logback.xml)
docker cp nacos-mysql:/home/nacos/conf ./修改mysql的信息（修改文件application.properties）
再次运行
docker run -d \
-e MODE=standalone \
-p 8848:8848 \
-p 9848:9848 \
-p 7848:7848 \
-v /data/nacos/conf:/mnt/data3/dockerfiles/nacos/config \
-v /data/nacos/logs:/mnt/data3/dockerfiles/nacos/logs \
-v /data/nacos/data:/mnt/data3/dockerfiles/nacos/data \
--name nacos-mysql \
--restart=always \
nacos/nacos-server:v2.2.3开启服务器端口：
centos开启防火墙端口
访问 ip:port/nacos
出现此页面即为安装成功。
springboot注册到nacos
先贴一个pom.xml

配置文件bootstrap.yml
spring:application:name: platformcloud:nacos:server-addr: ip:portconfig:file-extension: ymlgroup: DEFAULT_GROUPprefix: ${sping.application.name}springboot启动类
@SpringBootApplication
@EnableFeignClients
@EnableCaching
@EnableScheduling
@EnableDiscoveryClient
@RefreshScope
public class PlatformApplication {public static void main(String[] args) {SpringApplication.run(PlatformApplication.class, args);}}启动后就可以将服务注册到nacos中
python集成flask注册到nacos
首先下载nacos的sdk包
pip install nacos-sdk-pythonpython代码
import glob
import nacos
import threading
from flask import request, send_file
from flask import Flask, Response# nacos注册中心配置
SERVER_ADDRESS = "http://ip:port"
client = nacos.NacosClient(SERVER_ADDRESS)def service_register():"""ephemeral参数：是否是临时服务，应为false; 刚才上面也提到了，如果是 非临时实例，客户端就无需主动完成心跳检测。因此此处将服务注册为 非临时实例"""client.add_naming_instance("train", "ip", "port", ephemeral=False)# 测试nacos
@app.route("/testNacos/<testId>", methods=["GET"])
def testNacos(testId):resMap = {}print("nacos: {}".format(testId))resMap["code"] = "200"resMap["message"] = "hello nacos"resMap["data"] = str(testId)response = Response(json.dumps(resMap), status=200,content_type='application/json')return responseif __name__ == "__main__":# main()threading.Timer(5, service_register).start()app.run("0.0.0.0", 12352)启动后就可以将服务注册到nacos中
到这里，服务注册到nacos已经完成了
使用openfeign进行服务间的调用
@FeignClient("train")
public interface InferRpcService {@GetMapping("/testNacos/{testId}")VitsResponse testNacos(@PathVariable String testId);
}
测试类
@Test
public void testNacosPy(){System.out.println(trainService.testNacos("232323"));
}执行后
经测试没有问题
