Introduction
Polaris is a cloud-native service discovery and governance center. It can be used to solve the problem of service connection, fault tolerance, traffic control and secure in distributed and microservice architecture.
Functions:
- basic: service discover, service register and health check
- fault tolerance: circuit break and rate limit
- traffic control: request route and load balance
- secure: authenticate
Features:
- It provides SDK for high-performance business scenario and sidecar for non-invasive development mode.
- It provides multiple clients for different development languages, such as Java, Go, C++ and Nodejs.
- It can integrate with different service frameworks and gateways, such as Spring Cloud, gRPC and Nginx.
- It is compatible with Kubernetes and supports automatic injection of K8s service and Polaris sidecar.

Getting started
Preconditions
Prepare database
Please download and install MySQL, version requirement >=5.7, download available here: https://dev.mysql.com/downloads/mysql/5.7.html
Import SQL script
Point Script: ./store/defaultStore/polaris_server.sql, one can import through mysql admin or console.
Prepare golang compile environment
Polaris server end needs golang compile environment, version number needs >=1.12, download available here: https://golang.org/dl/#featured.
Build
chmod +x build.sh
./build.sh
After built, one can see 'polaris-server-release_${version}.tar.gz' package from the list.
Installation
Unzip package
Obtain polaris-server-release_${version}.tar.gz, and unzip.
Change polaris configuration
After unzipped, vi polaris-server.yaml, replace DB configuration's variable to real database information : ##DB_USER## (database username), ##DB_PWD##（database password）, ##DB_ADDR##（database address）, ##DB_NAME##（database name）
Execute Installation Script
chmod +x ./tool/*.sh
# install
./tool/start.sh
# test whether the process is successful
./tool/p.sh
After all, run ./p.sh, prompt Polaris Server, proof the installation is successful
Verify installation
curl http://127.0.0.1:8090
Return text is 'Polaris Server', proof features run smoothly
