开源项目学习之------AG-Admin环境搭建

原文地址： https://blog.csdn.net/u011781521/article/details/79056974

一、框架简介

AG-Admin是基于Spring Cloud微服务化开发平台，具有统一授权、认证后台管理系统，其中包含具备用户管理、资源权限管理、网关API管理等多个模块，支持多业务系统并行开发，可以作为后端服务的开发脚手架。代码简洁，架构清晰，适合学习和直接项目中使用。核心技术采用Eureka、Fegin、Ribbon、Zuul、Hystrix、JWT Token、Mybatis等主要框架和中间件，前端采用vue-element-admin组件。

模块说明:

二、环境搭建

(一)、导入源码

首先下载源码到本地，这里下载的2.2版本，最新的有可能有问题。。。

然后导入到IDEA中，并更新maven依赖，由于项目中使用了lombok，所有需要安装lombok插件，否则你的IDE会报代码缺失。

项目结构如下

├─ace-security
│  │  
│  ├─ace-admin----------------管理端服务层
│  │ 
│  ├─ace-auth-----------------鉴权中心
│  │ 
│  ├─ace-gate-----------------网关负载中心
│  │ 
│  ├─ace-center---------------服务注册中心
│  │   
│  ├─ace-monitor--------------统一监控中心
│  │
│  ├─ace-config---------------统一配置中心
│  │
│  ├─ace-api------------------公共服务接口包
│  │
│  ├─ace-demo-----------------示例服务代码
│  │
│  └─ace-sidebar--------------调用第三方语言

(二)、安装Redis与rabbitmq和node

Redis安装可参考我先前的zheng环境搭建篇,node安装也很简单一直下一步下一步，就行了，安装好之后，更换成淘宝源就行了。

2.1、rabbitmq安装

Rabbit MQ 是建立在Erlang OTP平台上，所以在安装rabbitMQ之前，需要先安装Erlang ，下载地址为http://www.erlang.org/downloads

下载好之后，双击进行安装

安装完成之后创建一个名为ERLANG_HOME的环境变量，其值指向erlang的安装目录

同时将%ERLANG_HOME%\bin加入到Path中

最后打开命令行，输入erl

如果出现erlang的版本信息就表示erlang语言环境安装成功；

然后下载Rabbitmq，下载地址为:http://www.rabbitmq.com/download.html

下载好之后，双击进行安装

默认安装的RabbitMQ 监听端口是5672,默认用户名：guest，密码：guest。

2.2、RabbitMQ-Plugins插件安装

这个插件相当于是一个管理界面，方便我们在浏览器界面查看RabbitMQ各个消息队列以及exchange的工作情况，安装方法是：打开命令行cd进入rabbitmq的sbin目录(我的目录是：C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.2\sbin)，输入：

rabbitmq-plugins enable rabbitmq_management
   
   

命令，稍等会会发现出现plugins安装成功的提示

然后重启服务，使用命令(此时最后以管理员运行CMD)：

net stop RabbitMQ && net start RabbitMQ
   
   

插件安装完之后，在浏览器输入http://localhost:15672进行验证

(三)、初始化数据

分别导入ace-admin/db/init.sql、ace-auth-server/db/init.sql 这两个脚本，导入成功之后，会创建ag_admin和ag_auth两个数据库以及以下一些表:

表竟然没有中文注释。。。。

(四)、配置hosts文件

    
    
127.0.0.1 ace-admin
127.0.0.1 ACE-ADMIN
   
   

修改项目里所有的defaultZone参数，他默认用的是docker，但是我们是这本地开发的，所以改成本地的

(五)、修改数据库配置文件

修改ace-admin/src/main/resources/application.yml、ace-gate/src/main/resources/application.yml这两个配置文件中连接数据库的一些信息:

(六)、按顺序运行main类：CenterBootstrap（ace-center）、ConfigServerBootstrap（ace-config）、AuthBootstrap（ace-auth-server）、AdminBootstrap（ace-admin）、GateBootstrap（ace-gate）

如果报以下错误MQ超时:

Caused by: org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused: connect at org.springframework.amqp.rabbit.support.RabbitExceptionTranslator.convertRabbitAccessException(RabbitExceptionTranslator.java:62) at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:368) at org.springframework.amqp.rabbit.connection.CachingConnectionFactory.createConnection(CachingConnectionFactory.java:565) at org.springframework.amqp.rabbit.core.RabbitTemplate.doExecute(RabbitTemplate.java:1430) at org.springframework.amqp.rabbit.core.RabbitTemplate.execute(RabbitTemplate.java:1411) at org.springframework.amqp.rabbit.core.RabbitTemplate.send(RabbitTemplate.java:712) at org.springframework.integration.amqp.outbound.AmqpOutboundEndpoint.send(AmqpOutboundEndpoint.java:134) at org.springframework.integration.amqp.outbound.AmqpOutboundEndpoint.handleRequestMessage(AmqpOutboundEndpoint.java:122) at org.springframework.integration.handler.AbstractReplyProducingMessageHandler.handleMessageInternal(AbstractReplyProducingMessageHandler.java:109) at org.springframework.integration.handler.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:127) ... 55 more Caused by: java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.waitForConnect(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:85) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:188) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:589) at com.rabbitmq.client.impl.SocketFrameHandlerFactory.create(SocketFrameHandlerFactory.java:50) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:907) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:859) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:799) at org.springframework.amqp.rabbit.connection.AbstractConnectionFactory.createBareConnection(AbstractConnectionFactory.java:352) ... 63 more
   
   

基本上就是MQ配置有问题。

如果报以下错误:

版本问题。。

全部启动之后

(七)、启动前端项目

首先下载UI：https://gitee.com/geek_qi/AG-Admin-v2.0 下载下来之后，解压如下

然后在该目录下执行以下命令安装依赖,用的是淘宝的源，不清楚地朋友可以百度node更换淘宝源:

cnpm install
   
   

安装成功之后，会多出一个node_modules目录

然后启动服务

    
    
# 本地开发 开启服务
npm run dev
   
   

他会自动打开浏览器，访问该页面

然后点击登陆。

登陆成功之后如上。。

(八)、部署nginx配置参考

nginx配置如下:

    
    
location / {
# 指向我们打包后上传的前端文件
root /opt/nginx/dist;
index index.html;
}
location /jwt/ {
# 转发请求到后端服务网关
proxy_pass http://127.0.0.1:8765/jwt/;
}
location /api/ {
proxy_pass http://127.0.0.1:8765/api/;
}
   
   

很简单，不会的可参考我前两篇文章的配置。。
