Elasticsearch运维篇_ES启动失败常见问题及解决办法整理

一、前言

近期接手生产Elasticsearch运维，为更好的掌握Elasticsearch的相关知识，也是在测试环境先搭建了EK(Elasticsearch-Kibana)集群用于学习，在初期安装部署中也是遇到一系列Elasticsearch相关问题，为此对遇到的问题及解决办法进行整理，后续还会对此块内容进行更新补充。

二、Elasticsearch介绍

1、Elasticsearch是搜索引擎

Elasticsearch在搜索引擎数据领域长期排名第一，Elasticsearch内核基于Lucene构建，支持全文搜索。Elasticsearch支持全文搜索，但在很多项目组中常被用于精确查询加速，查询条件多、速度快且可以任意组合，有些甚至常用Elasticsearch做Redis、Hbase等数据库的二级索引。

2、Elasticsearch是数据库

Elasticsearch不属于关系型数据库，其内部更新采用乐观锁、也无关系型数据库的ACID事务特性。Elasticsearch使用JSON格式承载数据模型，更类似文档数据库，相较于MongoDB，其更擅长基于查询搜索的分析型数据库。

三、Elasticsearch常用领域

1、全文检索

对比传统的Solr，Elasticsearch也是基于Lucene实现，是对Lucene进行二次封装，对Lucene调用进行了优化，但Elasticsearch更重量级，在分布式场景中表现更优。
Elasticsearch支持文件的上传、下载，可根据关键字搜索出相关文件。

2、应用查询

Elasticsearch擅长查询，这得益于其倒排索引核心算法，相较于基于B-Tree类型数据库查询性能更优，尤其是在数据量很大时，检索效率非常明显。

3、大数据应用

在大数据领域，Elasticsearch应用非常广泛，是大数据对外提供查询重要组成部分。Elasticsearch在大数据分析领域提供基于列示存储数据聚合、所支持的聚合功能甚多、且性能优异。

4、日志检索

作为ELK(Elasticsearch-Logstash-Kibana)日志检索三剑客之一，Elasticsearch起步于全文检索，加之其分布式架构特性，尤其适用海量日志快速检索。

5、监控领域

》Elasticsearch利用其倒排索引核心算法，加之日益强大的Elastic Stack生态圈，Elasticsearch也是支持众多时序数据场景，且性能不输众多时序数据库，所以使用Elasticsearch相关监控也是很好的选择。

6、人工智能-机器学习

今年来AI人工智能风头强劲，尤其是chatGPT推出以来，人工智能更是在众多领域广泛应用，Elasticsearch从6.3版本推出机器学习的功能，随着Elasticsearch版本的发展，其机器学习功能也更加强大，能高效提高检测数据质量，减少人力成本。

四、常见启动故障及解决办法

本部分总结了Elasticsearch常见启动故障及相应解决办法，后续会逐步更新本部分内容。

1、java.nio.file.AccessDeniedException故障及处理办法

**问题原因：

由于权限问题导致启动失败，原因是我在elasticsearch/conf/elasticsearch.yml中设置了path.data和path.logs,ES启动建议使用普通用户启动，root权限过大，初期未给path.data和path.logs设置普通用户属组，导致启动失败。

解决办法：

给path.data和path.logs设置普通用户属组。

2、BindTransportException故障及处理办法

问题原因：

该问题由于在elasticsearch/config/elasticsearch.yml设置了network.host: 192.168.0.0，导致无法分配请求的地址。

解决办法:

修改network.host:本机IP地址,如network.host:192.168.17.36，每台es服务器elasticsearch.yml的network.host要对应本机的IP地址。

**3、memory locking requested for elasticsearch process but memory is not locked故障及处理办法
**报错原因：

请求内存锁定，但内存未锁定导致，此问题和参数配置有关。
我在部署了ES后，希望通过服务的方式来启停es，创建了服务配置文件，内容如下：

cat > /usr/lib/systemd/system/elasticsearch.service << EOF
[Unit]
Description=Elasticsearch
Wants=network-online.target
After=network-online.target

[Service]
User=es
Group=es

ExecStart=/usr/local/elasticsearch/bin/elasticsearch
ExecReload=/bin/kill -HUP \$MAINPID
LimitNOFILE=65535
KillMode=process
Restart=no-failure

[Install]
WantedBy=multi-user.target
EOF

复制

然后执行如下命令:

[root@node1 bin]# /bin/systemctl daemon-reload
[root@node1 bin]# /bin/systemctl enable elasticsearch.service
[root@node1 bin]# /bin/systemctl start elasticsearch.service

复制

但在启动时报内存未锁定，启动失败。

**解决办法：

我首先尝试修改了elasticsearch/config下jvm.options文件，将-Xms4g及-Xmx4g取消前面注释，然后重新启动es服务，依然报同样错误。
后来查阅网上资料，修改/usr/lib/systemd/system/elasticsearch.service配置文件，在[Service]块中设置LimitMEMLOCK=infinity，此步骤操作后需要重新执行/bin/systemctl daemon-reload，然后启动es服务，这次启动成功。

五、总结

本次操作主要是基于Elasticsearch 7在Rocky 8操作系统上安装部署启动时所遇到的问题。
作为Elasticsearch日常运维管理的一部分，后续会根据日常生产及测试中的经验总结更多Elasticsearch相关知识进行输出，敬请期待。
千里之行，始于足下。
