# 后端开发文档 |
||||
|
||||
## 环境要求 |
||||
|
||||
* [Mysql](http://geek.analysys.cn/topic/124) (5.5+) : 必装 |
||||
* [JDK](https://www.oracle.com/technetwork/java/javase/downloads/index.html) (1.8+) : 必装 |
||||
* [ZooKeeper](https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper)(3.4.6+) ：必装 |
||||
* [Maven](http://maven.apache.org/download.cgi)(3.3+) ：必装 |
||||
|
||||
因EasyScheduler中escheduler-rpc模块使用到Grpc，需要用到Maven编译生成所需要的类 |
||||
对Maven不熟的伙伴请参考: [maven in five minutes](http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html)(3.3+) |
||||
|
||||
http://maven.apache.org/install.html |
||||
|
||||
## 项目编译 |
||||
将EasyScheduler源码下载导入Idea等开发工具后，首先转为Maven项目(右键点击后选择"Add Framework Support") |
||||
|
||||
* 执行编译命令： |
||||
|
||||
``` |
||||
mvn -U clean package assembly:assembly -Dmaven.test.skip=true |
||||
``` |
||||
|
||||
* 查看目录 |
||||
|
||||
正常编译完后，会在当前目录生成 target/escheduler-{version}/ |
||||
|
||||
``` |
||||
bin |
||||
conf |
||||
lib |
||||
script |
||||
sql |
||||
install.sh |
||||
``` |
||||
|
||||
- 说明 |
||||
|
||||
``` |
||||
bin : 基础服务启动脚本 |
||||
conf : 项目配置文件 |
||||
lib : 项目依赖jar包，包括各个模块jar和第三方jar |
||||
script : 集群启动、停止和服务监控启停脚本 |
||||
sql : 项目依赖sql文件 |
||||
install.sh : 一键部署脚本 |
||||
``` |
||||
