1、我的环境概览

• 操作系统：MacOS m1（aarch64）
• Elasticsearch ：7.16.2
• Zulu JDK 16 (和Elasticsearch 版本相对应即可，详见www.elastic.co/cn/support/… ）
• Gradle 7.2.2（Elasticsearch 是Gradle项目）
• IntelliJ IDEA 2021.3.1 在最新的idea里，JDK和Gradle可以不主动下载，在reload gradle项目时会弹出提示自动下载

2、源码下载

github.com/elastic/ela…

假设安装目录为 /Users/xiaobei/project/elasticsearch

---

3、启动IDEA

1、 File->open 打开项目

2、切换到想要的tag，这里以 v7.16.2为例

3、并下载对应版本的release包备用，release包结构如下

4、 在源码elasticsearch目录下新建一个自己的目录，这里我命名myhome，目录结构如下，再新建子目录config，plugins，modules

5、把release包的modules复制到源码的myhome/modules目录下

6、把config包的elasticsearch.yml , jvm.options, log4j2.properties复制到源码的myhome/config目录下

6.1、 修改elasticsearch.yml，添加参数

# 可自定义
cluster.name: xiaobei-testxxx
# 可自定义
node.name: xiaobei-testxxx-node
# 可自定义，我放在刚刚创建的myhome目录下
path.data: /Users/xiaobei/Project/elasticsearch/myhome/data
path.logs: /Users/xiaobei/Project/elasticsearch/myhome/logs
# 启动在本地
network.host: 127.0.0.1
# 启动端口号
http.port: 9200
# 集群的主节点，和node.name保持一致即可
cluster.initial_master_nodes: ["xiaobei-testxxx-node"]

6.2 在config包下添加policy文件，这里我命名为elasticsearch.policy，内容如下

grant {
        permission javax.management.MBeanTruxtPermission "register";
        permission javax.management.MBeanServerPermission "createMBeanServer";
        permission java.lang.RuntimePermission "createClassLoader";
        permission java.lang.RuntimePermission "getClassLoader";
        permission java.lang.RuntimePermission "setContextClassLoader";
        permission org.elasticsearch.secure_sm.ThreadPermission "modifyArbitraryThread";
        permission org.elasticsearch.secure_sm.ThreadPermission "modifyArbitraryThreadGroup";
 };

6.3 移动好文件的myhome文件夹结构如下

7、 统一jdk版本

7.1.、 File-> Project Structure

7.2.、 IntelliJ IDEA -> Preferences -> Build, Execution, Deployment -> Build Tools -> Gradle

8、 添加启动类配置

#5、JVM选项

-Des.path.home=/Users/xiaobei/Project/elasticsearch/myhome
-Des.path.conf=/Users/xiaobei/Project/elasticsearch/myhome/config
-Djava.security.policy=/Users/xiaobei/Project/elasticsearch/myhome/config/elasticsearch.policy
-Dlog4j2.disable.jmx=true
-Xmx4g
-Xms4g

#6、启动类路径

模块：elasticsearch.server.main 类全限定名：org.elasticsearch.bootstrap.Elasticsearch

#7、工作空间

你的elasticsearch源码目录

9、 build gradle项目（最新版的idea在gradle和jdk版本不对时，会自动弹出提示快捷下载）

10、启动项目，在浏览器能成功打开localhost:9200，大功告成
