龙芯 LoongArch64编译es7.17.20

下载es代码

• 下载地址

  github.com/elastic/ela...

下载好源码后，上传源码到需要编译的服务器

下载gradle版本

打开源码，查看对应es的gradle编译版本

cd ./elasticsearch-7.17.20/gradle/wrapper
vim gradle-wrapper.properties

下面是es7.17.20对应的gradle信息

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionSha256Sum=194717442575a6f96e1c1befa2c30e9a4fc90f701d7aee33eb879b79e7ff05c0
distributionUrl=https\://services.gradle.org/distributions/gradle-8.7-all.zip
networkTimeout=10000
validateDistributionUrl=true
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

下载gradle

services.gradle.org/distributio...

将下载的gradle包复制到 elasticsearch-7.17.20/gradle/wrapper路径下

修改gradle-wrapper.properties信息，distributionUrl删除前缀，从本地load gradle

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionSha256Sum=194717442575a6f96e1c1befa2c30e9a4fc90f701d7aee33eb879b79e7ff05c0
distributionUrl=gradle-8.7-all.zip
networkTimeout=10000
validateDistributionUrl=true
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

修改Architecture.java 文件，添加loongarch64架构支持

文件路径为：/elasticsearch-7.17.20/build-tools/src/main/java/org/elasticsearch/gradle/Architecture.java

package org.elasticsearch.gradle;

public enum Architecture {

    X64("x86_64", "linux/amd64"),
    AARCH64("aarch64", "linux/arm64");
    LOONGARCH64("loongarch64"); // ✅ 新增

    public final String classifier;
    public final String dockerPlatform;

    Architecture(String classifier, String dockerPlatform) {
        this.classifier = classifier;
        this.dockerPlatform = dockerPlatform;
    }

    public static Architecture current() {
        final String architecture = System.getProperty("os.arch", "");
        switch (architecture) {
            case "amd64":
            case "x86_64":
                return X64;
            case "aarch64":
                return AARCH64;
           case "loongarch64":            // ✅ 新增
                return LOONGARCH64;            
            default:
                throw new IllegalArgumentException("can not determine architecture from [" + architecture + "]");
        }
    }

}

编译es

执行下面的gradle命令，进行es编译

./gradlew :distribution:archives:linux-tar:assemble \
  -x :x-pack:plugin:ml:build \
  -x :x-pack:plugin:ml:bundlePlugin \
  -x :x-pack:plugin:ml:assemble \
  -x :x-pack:plugin:ml:processResources \
  -x :x-pack:plugin:ml:jar \
  -x :x-pack:plugin:ml:zip

构建成功后，包路径为：

distribution/archives/linux-tar/build/distributions/elasticsearch-7.17.20-SNAPSHOT.tar.gz

删除的x-pack-eql模块

路径如下:

elasticsearch-7.17.20-SNAPSHOT/modules/x-pack-eql

禁用ml等模块

修改es的配置config/elasticsearch.yml，添加如下配置:

xpack.security.enabled: false
xpack.ml.enabled: false
xpack.monitoring.enabled: false
xpack.watcher.enabled: false

注意事项

• 1.本文编译时，使用的jdk版本为openjdk-17构建
