首先在后台启动etcd

写一段go代码

package mainimport ("context""fmt"clientv3 "go.etcd.io/etcd/client/v3""time"
)func main() {// 创建客户端，连接etcdcli, err := clientv3.New(clientv3.Config{Endpoints:   []string{"127.0.0.1:2379"},DialTimeout: 5 * time.Second,})if err != nil {fmt.Printf("connect to etcd failed, err:%v\n", err)return}fmt.Println("connect to etcd success")defer cli.Close()str := `[{"path":"d:/logs/s4.logs","topic":"s4_logs"},{"path":"d:/logs/web.logs","topic":"web_logs"}`// put操作_, err = cli.Put(context.TODO(), "collect_log_conf", str)if err != nil {fmt.Printf("put to etcd failed, err:%v\n", err)return} get操作resp, err := cli.Get(context.TODO(), "collect_log_conf") // 获取指定Key的值if err != nil {fmt.Printf("get to etcd failed")return}for _, ev := range resp.Kvs {fmt.Printf("key：%s，value：%s\n", ev.Key, ev.Value)} delete 删除key//if _,err = cli.Delete(context.TODO(), "testetcd");err != nil{//	fmt.Println("delete key failed")//}else{//	fmt.Println("delete key success")//}
}

也可以直接使用ectdctl工具查看key

etcdctl.exe --endpoints=127.0.0.1:2379 get collect_log_conf
