shop_grpc's Introduction

一、shop项目所需的中间件

1. redis

docker run -d --name shop_redis --restart=always -p 6379:6379 redis

2. mysql

docker run -d --name shop_mysql --restart=always -p 3306:3306 -e MYSQL_ROOT_PASSWORD=shop123456 mysql

账号root

密码shop123456

3. consul

服务注册与发现

docker run -d --name shop_consul --restart=always -p 8500:8500 -p 8300:8300 -p 8301:8301 -p 8302:8302 -p 8600:8600/udp consul agent -dev -client=0.0.0.0

web控制台 http://192.168.139.130:8500

  • 8300：集群内数据的读写和复制
  • 8301：单个数据中心gossip协议通讯
  • 8302：跨数据中心gossip协议通讯
  • 8500：提供获取服务列表、注册服务、注销服务等HTTP接口；提供UI服务
  • 8600：采用DNS协议提供服务发现功能

4. nacos

配置中心

docker run -d --name shop_nacos --restart=always -e MODE=standalone -e JVM_XMS=512m -e JVM_XMX=512m -e JVM_XMN=256m -p 8848:8848 nacos/nacos-server

web控制台：http://192.168.139.130:8848/nacos/index.html

账号nacos 密码nacos

5. Elasticsearch

（1）新建data和config挂载目录

[root@go ~]# mkdir -p /data/elasticsearch/config
[root@go ~]# mkdir -p /data/elasticsearch/data

# 添加权限
[root@go ~]# chmod 777 -R /data/elasticsearch/
[root@go ~]# ll /data/elasticsearch/
总用量 0
drwxrwxrwx. 2 root root 31 10月 24 16:02 config
drwxrwxrwx. 2 root root  6 10月 24 15:58 data

（2）写入配置到elasticsearch.yml

[root@go ~]# echo "http.host: 0.0.0.0" >> /data/elasticsearch/config/elasticsearch.yml

（3）启动Elasticsearch

docker run --name shop_es --restart=always -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx128m" -v /data/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /data/elasticsearch/data:/usr/share/elasticsearch/data -v /data/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:7.17.6

-e "discovery.type=single-node" 设置为单节点

-e ES_JAVA_OPTS="-Xms64m -Xmx128m" 测试环境下，设置ES的初始内存和最大内存，否则导致过大启动不了ES

测试启动成功

[root@go ~]# curl localhost:9200
{
  "name" : "1a131380b19e",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "UKmfhXXjRAuEfgVSyXexdQ",
  "version" : {
    "number" : "7.17.6",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "f65e9d338dc1d07b642e14a27f338990148ee5b6",
    "build_date" : "2022-08-23T11:08:48.893373482Z",
    "build_snapshot" : false,
    "lucene_version" : "8.11.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

（4）启动kibana

注意！kibana的版本号需要和es版本号一致

# docker run --name shop_kibana --restart=always -e ELASTICSEARCH_HOSTS=http:自己的IP地址:9200 -p 5601:5601 -d kibana:7.17.6
[root@go ~]# docker run --name shop_kibana --restart=always -e ELASTICSEARCH_HOSTS=http:192.168.139.130:9200 -p 5601:5601 -d kibana:7.17.6

浏览器输入ip:5601进入web控制台

选择==Dev Tools==

执行GET /_cat/indices查看所有index

（5）集成ik中文分词器

下载对应版本ik

https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v7.17.6

解压后重命名为ik

移动到挂载的/data/elasticsearch/plugins目录

6. rocketmq

使用install压缩包通过docker-compose安装 web控制台：http://192.168.139.130:8080

7. jaeger

docker run -d --rm --name shop_jaeger -p6831:6831/udp -p16686:16686 jaegertracing/all-in-one:latest
