docker-compose搭建高可用多环境Apollo配置中心

docker-cmpose搭建高可用多环境Apollo配置中心

整体分五个部分


把mysql单独出来，作为常用公用MySQL数据库服务

搭建MySQL

创建mysql目录并初始化脚本

  1. 在/usr/local/目录下创建mysql目录
mkdir -p mysql && cd mysql
  1. 编写docker-compose.yml脚本
version: '3'
services:
  mysql:
    image: mysql:5.7.28
    container_name: mysql
    restart: always
    ports:
    - '3306:3306' # 这里需要暴露端口，用mysql客户端修改apollo一些配置
    environment:
      MYSQL_ROOT_PASSWORD: "123456"
    deploy:
      resources:
        limits:
          cpus: '30m'
          memory: '256M'
    networks:
    - nfc-networks
    volumes:
    - ./data:/var/lib/mysql
    - ./script:/docker-entrypoint-initdb.d/
    healthcheck:
      test: ["CMD","mysqladmin","-uroot","-p123456","ping","-h","localhost"]
      timeout: 2s
      interval: 10s
      retries: 5
      start_period: 5s

networks:
  nfc-networks:
    name: nfc-networks
    driver: bridge
    ipam:
      driver: default
      config:
      - subnet: 10.24.0.0/16
        gateway: 10.24.0.1
  1. 创建脚本目录
mkdir -p script && cd script

将apolloconfigdb.sql、apolloportaldb.sql拷贝至script，apolloconfigdb.sql复制成两份apolloconfigdbdev.sql和apolloconfigdbfat.sql，修改库名。

搭建eureka集群

  1. 创建eureka目录并初始化脚本
mkdir eureka && cd eureka
# 由于要搭建多环境，所以再加一层
mkdir eureka-dev && cd eureka-dev
  1. 编写docker-compose.yml脚本

    server configservice-dev-2:8080;
}
server {
    listen       8080;
    listen  [::]:8080;
    server_name  configservice.lhstack.com;
    root  /usr/share/nginx/html;
    client_max_body_size 50m;
    location / {
        proxy_pass http://configservice;
    }
}

configservice-fat下conf.d/configservice.conf

upstream configservice{
    server configservice-fat-1:8080;
    server configservice-fat-2:8080;
}
server {
    listen       8080;
    listen  [::]:8080;
    server_name  configservice.lhstack.com;
    root  /usr/share/nginx/html;
    client_max_body_size 50m;
