# Nacos: Dynamic *Na*ming and *Co*nfiguration *S*ervice [](https://gitter.im/alibaba/nacos?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge) [](https://www.apache.org/licenses/LICENSE-2.0.html) [](https://travis-ci.org/alibaba/nacos) ------- ## 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-0.3.0.zip for example. ``` unzip nacos-server-0.3.0.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 ``` For more details, see [quick-start.](https://nacos.io/en-us/docs/quick-start.html) ## Quick start for other open-source projects: * [Quick start with Nacos command and console](https://nacos.io/en-us/docs/quick-start.html) * [Quick start with dubbo](https://nacos.io/en-us/docs/use-nacos-with-dubbo.html) * [quick start with spring cloud](https://nacos.io/en-us/docs/quick-start-spring-cloud.html) * [Quick start with kubernetes](https://nacos.io/en-us/docs/use-nacos-with-kubernetes.html) ## Documentation You can view the full documentation from the [Nacos website](https://nacos.io/en-us/docs/what-is-nacos.html). ## Other Related Project Repositories * [nacos-spring-project](https://github.com/nacos-group/nacos-spring-project) provides the integration functionality for Spring. * [nacos-sync](https://github.com/nacos-group/nacos-sync) is a tool to synchronize the service registration information from other tools like eureka, zookeeper, etc, to Nacos. * [spring-cloud-alibaba](https://github.com/spring-cloud-incubator/spring-cloud-alibaba) provides the one-stop solution for application development over Alibaba middleware which includes Nacos. ### Contact * #### Gitter-[Nacos Gitter](https://gitter.im/alibaba/nacos) * #### Weibo-[Nacos Weibo](https://weibo.com/u/6574374908) * #### Segmentfault-[Nacos Segmentfault](https://segmentfault.com/t/nacos) * #### Mailing list-[nacos\_dev@linux.alibaba.com](mailto:nacos_dev@linux.alibaba.com).
