||
## What does it do
|
||
|
||
Nacos (official site: [http://nacos.io](http://nacos.io)) is an easy-to-use platform designed for dynamic service discovery and configuration and service management. It helps you to build cloud native applications and microservices platform easily.
|
||
|
||
Service is a first-class citizen in Nacos. Nacos supports almost all type of services，for example，[Dubbo/gRPC service](https://nacos.io/en-us/docs/use-nacos-with-dubbo.html)、[Spring Cloud RESTFul service](https://nacos.io/en-us/docs/use-nacos-with-springcloud.html) or [Kubernetes service](https://nacos.io/en-us/docs/use-nacos-with-kubernetes.html).
|
||
|
||
Nacos provides four major functions.
|
||
|
||
* **Service Discovery and Service Health Check**
|
||
|
||
Nacos makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. Nacos also provides real-time healthchecks of services to prevent sending requests to unhealthy hosts or service instance.
|
||
|
||
* **Dynamic Configuration Management**
|
||
|
||
Dynamic Configuration Service allows you to manage configurations of all services in a centralized and dynamic manner across all environments. Nacos eliminates the need to redeploy applications and services when configurations are updated，which makes configuration changes more efficient and agile.
|
||
|
||
* **Dynamic DNS Service**
|
||
|
||
Nacos supports weighted routing, making it easier for you to implement mid-tier load balancing, flexible routing policies, flow control, and simple DNS resolution services in the production environment within your data center. It helps you to implement DNS-based service discovery easily and prevent applications from coupling to vendor-specific service discovery APIs.
|
||
|
||
* **Service and MetaData Management**
|
||
|
||
Nacos provides an easy-to-use service dashboard to help you manage your services metadata, configuration, kubernetes DNS, service health and metrics statistics.
|
||

||
## Quick Start
|
||
It is super easy to get started with your first project.
|
||
|
||
#### Step 1: Download the binary package
|
||
|
||
You can download the package from the [latest stable release](https://github.com/alibaba/nacos/releases).
|
||
|
||
Take release nacos-server-0.9.0.zip for example.
|
||
```
|
||
unzip nacos-server-0.9.0.zip
|
||
cd nacos/bin
|
||
```
|
||
|
||
#### Step 2: Start Server
|
||
|
||
On the **Linux/Unix/Mac** platform, run the following command to start server with standalone mode:
|
||
```
|
||
sh startup.sh -m standalone
|
||
```
|
||
|
||
On the **Windows** platform, run the following command to start server with standalone mode. Alternatively, you can also double-click the startup.cmd to run NacosServer.
|
||
```
|
||
cmd startup.cmd -m standalone
|
||
```
