安装consul
下载地址 https://releases.hashicorp.com/consul/，将下载的consul.exe 文件目录添加到系统环境中，然后执行 consul agent -dev 启动，默认监听8500端口，可以访问 http://127.0.0.1:8500/ 进行查看
在golang项目中安装consul
go get github.com/hashicorp/consul
代码：
server.go 注册服务
package main
import (
"fmt"
consulapi "github.com/hashicorp/consul/api"
)
func main() {
consulConfig := consulapi.DefaultConfig()
fmt.Println(consulConfig)
consulClient, err := consulapi.NewClient(consulConfig)
if err != nil {
fmt.Println(err)
}
registerService := consulapi.AgentServiceRegistration{
ID: "1",
Tags: []string{"grpctest"},
Port: 8082,
Name: "grpc api",
Address: "127.0.0.1",
Check: &consulapi.AgentServiceCheck{
CheckID: "grpc api",
Interval: "5s",
Timeout: "5s",
TCP: "127.0.0.1:8082",
},
}
err = consulClient.Agent().ServiceRegister(®isterService)
fmt.Println(err)
}
client.go 发现可用服务
package main
import (
"fmt"
consulapi "github.com/hashicorp/consul/api"
)
func main() {
consulConf := consulapi.DefaultConfig()
consulClient, err := consulapi.NewClient(consulConf)
if err != nil {
fmt.Println(err)
}
serviceEntry, _, _ := consulClient.Health().Service("grpc api", "grpctest", false, &consulapi.QueryOptions{})
fmt.Println(serviceEntry[0].Service.Address)
fmt.Println(serviceEntry[0].Service.Port)
}
删除服务 destroy.go
package main
import (
"fmt"
consulapi "github.com/hashicorp/consul/api"
)
func main() {
consulConf := consulapi.DefaultConfig()
cli, err := consulapi.NewClient(consulConf)
if err != nil {
fmt.Println(err)
}
err = cli.Agent().ServiceDeregister("1")
fmt.Println(err)
}
