概述

Tars是腾讯开源的一个框架，定位是微服务治理框架，提供了系统性的解决方案。如下：

Tars应该是一款不错的工具，无赖我这里想搞一套可对比的基于java的RPC框架，2天收集了不少资料，但实在是无法走通哪怕一个最小的tars的helloworld。 主要原因：

1. 热度不够，自身提供的文档系统性不足
2. 架构上看，其java的实现体系结构基于web，缺乏继续探寻的动力
3. 其官方对比的文档看，与spring boot对比而言，缺乏优势

步骤

部署环境

Tars提供了一个平台来管理服务的部署。因此开发Tars服务，需要先部署好其管理平台。管理平台的数据基于MySQL存储。这里基于如下：

version: '3'
services:
  db:
    image: mysql:5.7
    volumes:
      - "/etc/localtime:/etc/localtime:ro"
      - "/home/gauss/soft/docker_app/mysql/dat:/var/lib/mysql"
      - "/home/gauss/soft/docker_app/mysql/cnf:/etc/mysql/conf.d/"
    restart: always
    ports:
     - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: password
    networks:
     - "my-soft-net"

networks:
  my-soft-net:
    external: true

version: '3'
services:
  framework:
    image: tarscloud/framework:stable
    container_name: tars-framework
    ports:
      - "3000:3000"
      - "3001:3001"
    restart: always
    networks:
     my-soft-net:
        ipv4_address: 192.168.0.10
    environment:
      MYSQL_HOST: "mysql_db_1"
      MYSQL_ROOT_PASSWORD: "password"
      MYSQL_USER: "root"
      MYSQL_PORT: 3306
    volumes:
      - /home/gauss/soft/docker_app/tars/framework/data:/data/tars:rw
      - "/etc/localtime:/etc/localtime:ro"
  node:
    image: tarscloud/tars-node:stable
    container_name: tars-node
    restart: always
    networks:
      my-soft-net:
        ipv4_address: 192.168.0.11
    volumes:
      - /home/gauss/soft/docker_app/tars/node/data:/data/:rw
      - "/etc/localtime:/etc/localtime:ro"
    environment:
      INET: eth0
      WEB_HOST: http://192.168.137.100:3000
    ports:
      - "9000-9010:9000-9010"

networks:
  my-soft-net:
    external: true
#    ipam:
#      config:
#      - subnet: 255.255.255.0/16
#        gateway: 192.168.0.1
