# microservices
使用micro微服务框架的一些例子,包含微服务开发中必备的鉴权,熔断,监控,链路追踪,跨域等## 主要内容
- 扩展micro的API网关功能
- 跨域
- JWT鉴权
- 熔断
- prometheus监控
- 链路追踪
- gin开发微服务service
- 熔断
- prometheus监控
- 链路追踪
- 内部服务采用grpc通信
- 服务健康检查
### 实现详解
各部分实现,都在博客中有相应博文讲解
[个人博客](https://note.mogutou.xyz/category/go-micro)## 跨域配置
要实现跨域,只需要在 micro api(micro API 网关)注册相关插件,并且通过命令行指定跨域相关信息即可。
```go
plugin.Register(cors.NewPlugin())
``````bash
micro api
--cors-allowed-headers=X-Custom-Header,X-Header
--cors-allowed-origins=someotherdomain.com,xx.com
--cors-allowed-methods=POST
```> 本项目使用consul的K/V存储来模拟一个配置中心。在每一个使用到lib/token包的服务都会在main函数里传递consul地址和JWT私钥的加载路径。在srv/user服务中同样,使用consul K/V 来存储mysql数据库的配置。在启动服务之前,需要现在consul的K/V中设置好这些配置。

- consul (服务发现,K/V配置)
- prometheus (监控)
- jaeger (链路追踪)
- hystrix-dashboard (hystrix熔断仪表盘)
- mysql> prometheus 参考配置文件

```### docker启动参考命令
- consul
> docker run --name consul -d -p 8500:8500/tcp consul agent -server -ui -bootstrap-expect=1 -client=0.0.0.0
- prometheus (启动时依赖本机配置文件 `/tmp/conf.yml` , 可更改命令自定义路径)
> docker run --name prometheus -d -p 0.0.0.0:9090:9090 -v /tmp/conf.yml:/etc/prometheus/prometheus.yml prom/prometheus
- jaeger
> docker run -d --name jaeger \
-e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \
-p 5775:5775/udp \
-p 6831:6831/udp \
-p 6832:6832/udp \
-p 5778:5778 \
-p 16686:16686 \
-p 14268:14268 \
-p 9411:9411 \
jaegertracing/all-in-one:1.6
- hystrix-dashboard
> docker run --name hystrix-dashboard -d -p 8081:9002 mlabouardy/hystrix-dashboard:latest> hystrix数据监控
http://localhost:8081/hystrix.stream- mysql
> docker run --name mysql -e MYSQL_ROOT_PASSWORD=123 -d -p 3306:3306 mysql## 快速体验
- 使用docker 启动consul jaeger hystrix-dashboard (上面有参考命令,复制粘贴执行即可)- 打开浏览器,进入 http://localhost:8500,进入K/V存储设置JWT私钥配置(参考上面的截图)
- jaeger UI http://localhost:16686
- hystrix-dashboard UI http://localhost:8081/hystrix, 输入 http://{ip}:81/hystrix.stream , 此处ip为本机ip,因为hystrix-dashboard是容器启动的,无法直接访问本机127.0.0.1
- 启动API网关:
```
cd micro && make run
```
- 启动user API服务:
```
cd api/user && make run
```
- 启动hello 服务:
```
cd srv/hello && make run
```
- 浏览器访问 http://127.0.0.1:8080/user/test ,或者使用其他工具 GET 127.0.0.1:8080/user/test![image](https://github.com/Allenxuxu/microservices/raw/master/.screenshots/consul-service.png)
