【谷粒商城开发笔记一】初步搭建环境_谷粒商城docker安装环境搭建

一、环境搭建

一种设计风格–微服务

微服务是指把一个架构复杂庞大的软件拆分成一个个功能模块，或者说一个个小服务，采用轻量级通信机制，一般是HTTP API

弹幕大多数说电脑至少需要16G内存

1.1 安装Linux虚拟机

virtualBox6.0是开源的去官网直接下载即可，但是要注意开启CPU虚拟化才能开始安装

首先确认自己电脑是否已经开启了CPU虚拟化，打开任务管理器->性能->CPU，观察虚拟化字段是否已启动

下载完以后要在此处修改虚拟机安装路径

安装镜像Linux Vagrant2.25

下载完vagrant以后要设置环境变量

1）利用镜像安装centos7

vagrant init centos7 https://mirrors.ustc.edu.cn/centos-cloud/centos/7/vagrant/x86_64/images/CentOS-7.box
1

2）开始下载

遇见如下报错

 Could not create a directory 'D:\xxx\vmFile\centos-7-1-1.x86_64_1716951173879_75099' to save the settings file (VERR_ACCESS_DENIED)
1

最后重新设置了virtualBox全局设定路径才行

每次开机使用

vagrant up
vagrant ssh
1
2

为虚拟机设置静态ip
具体操作如下
》首先，本机cmd执行ipconfig
找到VirtualBox虚拟网卡网址
进入VagrantFile文件中，找到如下行

# config.vm.network "private_network", ip: "192.168.xx.10"
1

将上面改为virtualbox同网段，并取消注释#

》然后，重新启动虚拟机
vagrant reload

》最后，登录虚拟机互相ping

# windows
 ipconfig
1
2

#linux
ip addr
1
2

1.2 安装docker

docker下载地址
安装前先卸载

安装依赖包
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安装docker
sudo yum install docker-ce docker-ce-cli containerd.io
添加镜像

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
1

启动docker

sudo systemctl start docker

开机自启

sudo systemctl enable docker

添加docker镜像加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-‘EOF’
{
“registry-mirrors”: [“https://aszg8dso.mirror.aliyuncs.com”]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

1.3 docker安装MySQL

sudo docker pull mysql:5.7

docker run -p 3306:3306 --name mysql
-v /mydata/mysql/log:/var/log/mysql
-v /mydata/mysql/data:/var/lib/mysql
-v /mydata/mysql/conf:/etc/mysql
-e MYSQL_ROOT_PASSWORD=root
-d mysql:5.7

每次docker run就会启动一个容器

进入某ID容器
docker exec -it mysql /bin/bash
查看正在运行中的容器
docker ps

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
init_connect=‘SET collation_connection = utf8_unicode_ci’
init_connect=‘SET NAMES utf8’
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
skip-name-resolve

重启服务
docker restart mysql

开机自动启动mysql
docker update mysql --restart=always

1.4 docker安装redis

docker pull redis:5.0.5

mkdir -p /mydata/redis/conf
touch /mydata/redis/conf/redis.conf

docker run -p 6379:6379 --name redis -v /mydata/redis/data:/data
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf
-d redis:5.0.5 redis-server /etc/redis/redis.conf

配置缓存持久化

二、创建项目注意事项

2.1 需要注意springboot的版本

如果更改之后openfeign依赖找不到，在该依赖下面加上版本
找不到2.1.8版本的，先用新版本创建，然后手动更改

2.2 安装node.js

亲测 node 14.15.0版本可以跑起来
10.24.1在执行npm install会报错，换了14.21.3

npm config set registry http://registry.npm.taobao.org/

重启vscode在控制台执行
npm install
会在当前路径下多出文件夹node_modules

重新执行install要执行
npm cache clean --force
在cmd中执行最终成功

运行起来fast vue
npm run dev

renren generator配置
在pom中纳管该模块

修改yml文件

修改proprities文件

修改controller生成模板中的代码

运行generator下面的主函数，进入下页面
逆向生成所有表

三、代码部分

3.1 @Data

加了这个注解就不需要get set方法，依赖lombok

3.2 导入Common pom依赖

导入mybatis-plus maven坐标

导入mysql驱动要关注版本适配，mysql版本 vs 驱动版本

3.2 maven配置中的scope字段

见3.2中描述

3.3 @MapperScan

@MapperScan(“com.atguigu.gulimall.product.dao”)
告诉主函数mapper.java文件在哪里
需要在yml文件中配置xml文件路径
在这里插入图片描述

3.4 @TableId

标识主键属性，需要在yml文件中配置自增逐渐

3.5 springboot版本引发的@test爆红

import org.junit.jupiter.api.Test 用在Spring Boot 2.2.X以后
import org.junit.Test用在2.2.x之前

3.7 遇见报错

nested exception is io.seata.common.exception.NotSupportYetException: not support register type: null，在本链接得到启发
具体报错为
