基于Kettle开发的web版数据集成开源工具(data-integration)-部署篇

📚第一章 前言

📗背景

在前面的ETL专栏中有提到，最近一直在寻找基于Kettle开发的web版开源工具，后面都放弃准备研究kettle源码了，结果遇到了一款，今天先来研究下Linux环境手动部署（官方给的都是docker方式部署，需要搭建docker、mvn、node、npm等环境，太复杂了！）

📗目的

本身公司有数据中台产品，只是需要Kettle任务绘制这一块内容

📗总体方向

参考该开源产品核心代码

📚第二章 下载编译

📗下载

下载地址：https://github.com/young-datafan-ooooo1/data-integration

📗编译

导入开发工具进行编译：

mvn clean install -Prelease  -Dcheckstyle.skip=true -Dmaven.test.skip=true -Dmaven.javadoc.skip=true

📚第三章 部署

📗准备工作

📕 安装数据库&redis&consul

• 数据源：使用MySQL数据库，没有的自行安装(docker安装mysql-建议本地手动安装mysql,这是之前安装docker练手用的，需要可以参考)，博主使用的是8.0版本，建库语句如下供参考

  CREATE DATABASE `dataintegration_db`;
  create user 'stelladp'@'%' identified by 'Renxiaozhao@2023';
  grant create,alter,drop,select,insert,update,delete,INDEX,REFERENCES on dataintegration_db.* to stelladp@'%';
  flush privileges; 
  

  
• 安装redis，可参照redis安装使用及告警处理
  
• 安装consul,参照Linux安装consul的两种方式（在线和离线）
  

📕 修改配置文件的数据库、redis、consul信息

修改所有模块的application-local.yaml和bootstrap.yaml文件，涉及数据库、redis、consul的地方全都改掉

📘 /dataintegration-gateway/src/main/resources/application-local.yaml修改用户认证服务SSO

id: dataintegration-common-sso-provider
#uri: lb://dataintegration-common-sso-provider
uri: http://localhost:10217/oauth/

📗服务器-应用目录结构

├─data-integration
│  └─bin     --存放启停脚本
│  └─conf    --存放配置文件（暂未用到，直接使用的jar包中的脚本）
│  └─lib     --jar包文件
│  └─logs    --日志目录
│  └─ui      --前端部署文件

📗重新编译并上传jar包

修改完配置，重新编译项目，找到所有模块的target目录下的jar包（有兴趣的可以尝试修改pom.xml文件，统一打包到某一路径下），上传到服务器


订正：只需要provider目录下面的jar包和gateway的jar包

-rw-rw-r--. 1 opensource opensource  93704942 1月   2 18:06 dataintegration-file-management-provider-1.0.0-SNAPSHOT.jar
-rw-rw-r--. 1 opensource opensource  66606827 1月   2 18:04 dataintegration-gateway-1.0.0-SNAPSHOT.jar

-rw-rw-r--. 1 opensource opensource  63207137 1月   2 18:05 dataintegration-sys-management-provider-1.0.0-SNAPSHOT.jar

📗启动后台服务

启动脚本如下：

#! /bin/bash
APP_LIB=/home/opensource/app/data-integration/lib
APP_LOGS=/home/opensource/app/data-integration/logs

echo "启动系统管理模块..................."
exec nohup java -jar ${APP_LIB}/dataintegration-sys-management-provider-1.0.0-SNAPSHOT.jar > ${APP_LOGS}/sys.log 2>&1 &

echo "启动分组管理模块..................."
exec nohup java -jar ${APP_LIB}/dataintegration-group-provider-1.0.0-SNAPSHOT.jar > ${APP_LOGS}/group.log 2>&1 &

echo "启动服务网关模块..................."
exec nohup java -jar ${APP_LIB}/dataintegration-gateway-1.0.0-SNAPSHOT.jar > ${APP_LOGS}/gateway.log 2>&1 &

echo "启动脚本管理模块..................."
exec nohup java -jar ${APP_LIB}/dataintegration-project-provider-1.0.0-SNAPSHOT.jar > ${APP_LOGS}/project.log 2>&1 &

echo "启动单点登录模块..................."
exec nohup java -jar ${APP_LIB}/dataintegration-sso-provider-1.0.0-SNAPSHOT.jar > ${APP_LOGS}/sso.log 2>&1 &

echo "启动模型管理模块..................."
exec nohup java -jar ${APP_LIB}/dataintegration-model-management-provider-1.0.0-SNAPSHOT.jar > ${APP_LOGS}/model.log 2>&1 &

echo "启动文件管理模块..................."
exec nohup java -jar ${APP_LIB}/dataintegration-file-management-provider-1.0.0-SNAPSHOT.jar > ${APP_LOGS}/file.log 2>&1 &

echo "启动数据集成运行模块..................."
#exec nohup java -jar ${APP_LIB}/dataintegration-run-management-provider-1.0.0-SNAPSHOT.jar  > ${APP_LOGS}/run.log 2>&1 &
#exec nohup java -jar ${APP_LIB}/dataintegration-run-management-provider-1.0.0-SNAPSHOT-ark-biz.jar  > ${APP_LOGS}/run.log 2>&1 &
exec nohup java -jar ${APP_LIB}/dataintegration-run-management-provider-1.0.0-SNAPSHOT-ark-executable.jar  > ${APP_LOGS}/run.log 2>&1 &

其中文件模块和运行模块启动失败，不知道有没有影响，先跳过不管，最后会统一放到问题记录章节处理

订正：file服务需要hdfs等存储环境，启动失败只会影响涉及文件的任务无法使用，run服务启动失败，会导致页面报错，很多查询接口都会报错，按照上面的脚本启动应该没有问题，一开始启动失败是因为选错了jar包

📕consul监控页面可以看到启动成功的服务

file服务忽略，正常应该有7个服务

📗前端部署

可参照smartKettle离线部署及问题记录中的前端部署章节，需要一些基础环境，这里不在赘述

📕编译

• 博主使用的VSCode工具，导入前端项目，首先npm install
  
• 编译打包npm run build
  
  
• dist目录对应就是部署文件
  
• 上传到服务器
  

📕nginx配置

同样参照参照smartKettle离线部署及问题记录中的nginx配置章节，需要安装nginx，这里不在赘述

server {
    listen       8785;
    server_name  localhost;

    location / {
        root /home/opensource/app/data-integration/ui/dist;
        try_files $uri $uri/ /index.html;
        index  index.html index.htm;
    }
    location /cloud {
        alias /home/opensource/app/data-integration/ui/dist;
        index  index.html index.htm;
        try_files $uri $uri/ /cloud/index.html;     #4.重定向,内部文件的指向
    }

    location /api {
        proxy_pass http://localhost:10200/api/;
        proxy_set_header Host $host:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }
}

📕登录验证

用户密码admin/Prime@2020,登录失败😭

错误原因参考下面的问题二,修复后可以正常登录

run服务启动成功后，也面正常展示

??问题记录

?问题一：-cp方式启动报错：找不到类

?解决方式：直接jar包启动

?问题二：Failed to handle request…10200/api/dataintegration-common-sso-provider/oauth/token

?原因：hosts文件被注释掉了

?解决方式：取消注释，重启gateway服务

放开注释：

不要忘了重启gateway服务:

exec nohup java -jar /home/opensource/app/data-integration/lib/dataintegration-gateway-1.0.0-SNAPSHOT.jar > /home/opensource/app/data-integration/logs/gateway.log 2>&1 &

?问题三：新建集成操作报错

?原因：运行模块没启动成功导致的

查看gateway日志， dataintegration-di-run-management-provider没启动成功导致

• dataintegration-run-management-provider-1.0.0-SNAPSHOT.jar 中没有主清单属性

  [opensource@bigdata02 logs]$ less run.log 
  nohup: 忽略输入
  /home/opensource/app/data-integration/lib/dataintegration-run-management-provider-1.0.0-SNAPSHOT.jar中没有主清单属性
  

  • 错误解释：缺少Main-Class属性
    
• 解决方式：启动dataintegration-run-management-provider-1.0.0-SNAPSHOT-ark-executable.jar

dataintegration-run-management-provider下面有三个jar包，真正配置DiRunManagementApplication的是dataintegration-run-management-provider-1.0.0-SNAPSHOT-ark-biz.jar（结果走了弯路，实际应该启动的是dataintegration-run-management-provider-1.0.0-SNAPSHOT-ark-executable.jar）
  
  弯路从这开始…（又没选对启动jar包）
  
  

?解决方式：正确应该启动的是dataintegration-run-management-provider-1.0.0-SNAPSHOT-ark-executable.jar

正确应该是启动dataintegration-run-management-provider-1.0.0-SNAPSHOT-ark-executable.jar：

启动成功后，页面正常

?问题五：DiRunManagementApplication启动报错·Exception in thread “main” java.lang.NoClassDefFoundError: org/springframework/boot/builder/SpringApplicationBuilder
