1. Introduction to Nacos

1.1 Nacos Overview

Nacos is a new open source project launched by Alibaba. It is a dynamic service discovery, configuration management and service management platform that makes it easier to build cloud-native applications.

Nacos is dedicated to helping you discover, configure and manage microservices. Nacos provides a set of easy-to-use feature sets to help you quickly realize dynamic service discovery, service configuration, service metadata, and traffic management.

Nacos helps you build, deliver and manage microservice platforms more agilely and easily. Nacos is a service infrastructure for building a “service”-centric modern application architecture (such as microservice paradigm, cloud native paradigm)

Nacos supports the following core features:

• 1) Service discovery: It supports DNS and RPC service discovery, and also provides various service registration methods such as native SDK and OpenAPI, and various service discovery methods such as DNS, HTTP and API.
• 2) Service health monitoring: Nacos provides real-time health checks on services, preventing requests from being sent to unhealthy hosts or service instances.
• 3) Dynamic configuration service: Nacos provides a unified configuration management function, which can help us manage the application configuration and service configuration of all environments in a centralized, external and dynamic manner.
• 4) Dynamic DNS service: Nacos supports dynamic DNS service weight routing, which allows us to easily implement middle-tier load balancing, more flexible routing strategies, traffic control, and simple DNS resolution services for the data center intranet.
• 5) Service and metadata management: Nacos supports the management of all services and metadata in the data center from the perspective of microservice platform construction, including management service description, life cycle, service static dependency analysis, service health status, service Traffic management, routing and security policies, service SLAs, and the most important metrics statistics.

1.2 Common Registration Center

• Eureka (native, 2.0 encounters a bottleneck and stops maintenance)
• Zookeeper (supported, professional standalone product. Ex: dubbo)
• Consul (native, GO language development)
• Nacos
  Compared with Spring Cloud Eureka, Nacos is more powerful.
  Nacos = Spring Cloud Eureka + Spring Cloud Config
  Nacos can be integrated with Spring, Spring Boot, Spring Cloud, and can replace Spring Cloud Eureka, Spring Cloud Config.
  Dynamic configuration changes are realized through Nacos Server and spring-cloud-starter-alibaba-nacos-config.
  Realize service registration and discovery through Nacos Server and spring-cloud-starter-alibaba-nacos-discovery.

2.Docker install Nacos

2.1 Pull mirror image

mkdir -p /home/kent/Tools/Nacos/logs/ #New logs directory
mkdir -p /home/kent/Tools/Nacos/conf/
vim /home/kent/Tools/Nacos/conf/application.properties #Modify configuration file

2.2 Mount directory for mapping to container

docker run -id --name openresty -p 80:80 sevenyuan/openresty

2.3 mysql Create a new nacos database and execute the script sql script
