项目官网：Cron-Job 分布式任务调度平台

Gitee仓库：cron-job: cron-job,定时任务,分布式,任务调度平台,简单易用,超低延迟,支持用户权限管理,多语言客户端,多租户接入,分布式任务调度平台

GitHub仓库：GitHub - HoraceDH/cron-job: cron-job,定时任务,分布式,任务调度平台,简单易用,超低延迟,支持用户权限管理,多语言客户端,多租户接入,分布式任务调度平台


一、环境要求

  • OS：支持Linux、Windows、MacOS，文中以CentOS为例。
  • Java：1.8+，官方用的是：1.8.0_391，64位。
  • MySQL：5.7+，官方用的是： 5.7.35-log Source distribution。


二、发行版下载地址

  • 下载发行版
  • GitHub：https://github.com/HoraceDH/cron-job/releases
  • Gitee：https://gitee.com/HoraceDH/cron-job/releases
  • 解压文件，这里以gitee仓库为例，下载最新的版本，解压后会得到如下文件内容：
  • cronjob-examples：示例代码，可直接运行
  • 包含原生Java版本的 example-executor
  • SpringBoot版本的 example-executor-starter
  • cronjob-managerui：管理后台UI
  • cronjob-scheduler：调度器，负责任务调度的服务端
  • mysql.sql：完整的数据库初始化脚本

三、初始化数据库

  • 初始化SQL，找到mysql.sql文件，进入到MySQL命令行中，执行以下命令即可完成初始化，其中path替换为自己的路径：
source /path/mysql.sql
  • 成功后，会产生cron-job库，并包含如下表：

四、调度器服务端部署

1. 部署第一台实例

1.1 修改配置文件

  • 文件路径etc/application.properties：
############# 调度器配置 #############
# 用于标识实例的唯一性
server.id=1
############# 调度器配置 #############

############# 数据源配置 #############
database.url=jdbc:mysql://localhost:3306/cron-job?useUnicode=true&characterEncoding=utf-8&useSSL=false&allowPublicKeyRetrieval=true
database.username=horace
database.password=SGJIWkjfdsof923847
############# 数据源配置 #############

############# Tomcat配置 #############
# Tomcat服务配置
server.port=9527
############# Tomcat配置 #############
  • 主要修改以下配置：
  • server.id：用于标识实例的唯一性，每个实例必须唯一。
  • server.port：服务端口，如果在同个机器部署，则需要修改端口，保证端口不冲突。
  • database.url：数据库连接地址。
  • database.username：数据库用户名。
  • database.password：数据库密码。

1.2 启动第一台实例

  • 执行命令：
sh start.sh
  • 查看日志输出，以下表示启动成功，有错则需要看日志排错，日志路径logs/app.log：

2. 部署第N台实例

  • 拷贝一份cronjob-scheduler，作为第N台实例，按照第一台实例的方式修改配置文件即可。
  • 如若部署更多实例，按照第一台实例的做法，依次部署即可，注意修改server.id以及相关配置。

五、管理后台UI部署

1. 存放静态资源

管理后台UI可以在发布包中找到cronjob-managerui目录，将cronjob-managerui放到合适的目录下，该目录就是打包后的前端文件。

2. Nginx配置

参照如下模板配置即可，注意修改对应的信息：

upstream cron_job.server {
    # 配置多个调度器地址，用于负载均衡
    server 127.0.0.1:9527;
    server 127.0.0.1:9528;
}

server {
    listen  80;
    server_name 127.0.0.1;
    error_log   logs/127.0.0.1.error.log   error;
    access_log  logs/127.0.0.1.access.log  main;

    # 管理后台UI静态资源
    location / {
        # 用于配合ant.design browserHistory 使用
        try_files   $uri $uri/index.html /index.html;
        root    /Users/horace/Downloads/cron-job-v1.0.1/cronjob-managerui;
        index   index.html;
    }

    # 管理后台API接口
    location /manager-api {
        proxy_pass  http://cron_job.server;
        proxy_set_header    X-Forwarded-Proto $scheme;
        proxy_set_header    Host              $http_host;
        proxy_set_header    X-Real-IP         $remote_addr;
    }

    # 开放API接口
    location /openapi {
        proxy_pass  http://cron_job.server;
        proxy_set_header    X-Forwarded-Proto $scheme;
        proxy_set_header    Host              $http_host;
        proxy_set_header    X-Real-IP         $remote_addr;
    }
}

3. 启动Nginx

访问http://127.0.0.1，实际访问地址根据自身部署的站点情况调整，实际生产部署需要配置域名。

4. 登录任务调度平台

看到如下页面时，说明部署成功，输入账号密码 admin/admin 进入系统：

六、启动示例工程

1. 进入目录

进入
cronjob-examples/example-executor目录，并执行如下命令：

sh start.sh

2. 检查执行器日志

出现以下表示启动成功，其中cron job executor register success表示执行器注册成功，cron job task register success执行器任务注册成功。

2025-02-18 17:59:40.855 INFO  [main]c.h.c.e.s.TaskService - found cron job task, TaskConfig{tenant='horace', method='cn.horace.cronjob.examples.tasks.DemoCronTask.handle', name='普通测试任务', appName='example-executor', appDesc='普通示例执行器', tag='common', remark='', cron='* * * * * ?

3. 启动任务

  • 登录管理后台，点击任务管理，点击启动任务，即可开始任务的调度。

4. 查看调度日志

可以看到，任务的调度很准时！
