可能是全网首个支持阿里云Elasticsearch Xapck鉴权的Skywalking
对Skywalking有兴趣的同学参见:年轻人的第一个APM-Skywalking
之前在搭建Skywalking的时候发现,官方Skywalking 5.X并支持有鉴权的Elasticsearch.
而我司有其他需求已经购买了阿里云的Elasticsearch,咨询过阿里云技术支持后他们表示并不能去掉鉴权,所以只好自己想办法了.
又在Skywalking技术群问了一圈,有其他人也遇到过类似的问题,但是最后还是选择自建ES了.
实在不想自己再浪费精力去搭建ES了,还是觉得可以尝试一下别的方案.
然后咨询了一下wusheng大大之后,他说可以自己尝试换一个支持XPack鉴权的Client,应该没什么太大的问题.
于是就开始了"填坑"之旅.
首先是引入x-pack-transport支持
apm-collector/apm-collector-component/client-component/pom.xml
<dependency>
<groupId>org.elasticsearch.client</groupId>
<artifactId>x-pack-transport</artifactId>
<version>${elasticsearch.client.version}</version>
</dependency>
<repositories>
<repository>
<id>elasticsearch-releases</id>
<url>https://artifacts.elastic.co/maven</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
接着在 ...in/java/org/apache/skywalking/apm/collector/client/elasticsearch/ElasticSearchClient.java
加入PreBuiltXPackTransportClient的初始化
private final String securityUser;
private PreBuiltXPackTransportClient initXPackClient() {
Settings settings = Settings.builder()
.put("cluster.name", clusterName)
.put("xpack.security.transport.ssl.enabled", false)
.put("xpack.security.user", securityUser)
.put("client.transport.sniff", false).build();
return new PreBuiltXPackTransportClient(settings);
}
private PreBuiltTransportClient initClient() {
Settings settings = Settings.builder() Settings settings = Settings.builder()
.put("cluster.name", clusterName) .put("cluster.name", clusterName)
.put("client.transport.sniff", clusterTransportSniffer) .put("client.transport.sniff", clusterTransportSniffer)
.build(); .build();
return new PreBuiltTransportClient(settings);
}
// 新增 private final String securityUser;
// 判断这个变量是不是null或者空字符串,如果是就默认初始化,不是则使用initXPackClient初始化
// 改一下initialize 方法
private final String securityUser;
@Override
public void initialize() throws ClientException {
if (securityUser == null || "".equals(securityUser)) {
client = initClient();
} else {
client = initXPackClient();
}
然后还要把apm-collector/pom.xml的elasticsearch.client.version 版本改成5.3.3.
改完之后因为5.3.3和原来5.5.0有点不一样,需要修改一下很几个地方的代码.
这时候建议直接使用IDEA build 一下,哪里报错改哪里就好.
主要都是 searchResponse.getHits().totalHits 改成searchResponse.getHits().totalHits()
神奇发现5.5.0版本的ES Client把5.3.3的searchResponse.getHits().totalHits() 方法改成了属性.
不经感慨都是人才啊...
别的一些基本都是引入 import org.elasticsearch.action.bulk.byscroll.BulkByScrollResponse;
全部代码在这里:liguobao/incubator-skywalking
完整改好的代码在liguobao/incubator-skywalking
同时配置的时候添加一下 securityUser参数,如果ES有鉴权就传入,没有的话就不传,这样就达到鉴权和不鉴权两种需求的兼容了.
支持xpack的docker部署方案

Dockerfile说明
apache-skywalking-apm-incubating.tar.gz为支持ES X-Pack修改后打包出来的压缩包,此仓库没有这个文件的.
可以去QQ群:Apache SkyWalking交流群(392443393)群文件中下载apache-skywalking-apm-incubating-xpack.tar.gz
或者自行编译liguobao/incubator-skywalking/tree/5.x 此版本的源码.
编译步骤:
# Prepare git, JDK8 and maven3
git clone https://github.com/liguobao/incubator-skywalking.git
cd incubator-skywalking/
git checkout 5.x
#Switch to the tag by using git checkout [tagname] (Optional, switch if want to build a release from source codes)
git submodule init
git submodule update
Run ./mvnw clean package -DskipTests
#All packages are in /dist.(.tar.gz for Linux and .zip for Windows).
Docker 镜像名称:liguobao/skywalking-docker
拉取镜像(Pull Image):
docker pull liguobao/skywalking-docker:5.0.RC2.xpack
运行镜像(Run)for ES xpack:
docker run -p 8080:8080 -p 10800:10800 -p 11800:11800 -p 12800:12800 -e ES_CLUSTER_NAME=elasticsearch -e ES_ADDRESSES=192.168.2.96:9300 -e SECURITY_USER='elastic:password' -d liguobao/skywalking-docker:5.0.RC2.xpack
- 使用浏览器访问
http://localhost:8080
即可. - 日志挂载

后记
本来还打算把代码提给主仓库的,但是wusheng 大大说xpack客户端和Apache要求的授权有冲突,遂...
那就留着自己玩了.
拜...
