Logstash给Elasticsearch无法访问错误

标签： elasticsearch logstash

我正在尝试将Logstash与Elasticsearch连接，但无法使其正常工作。 我的Elasticsearch在localhost：9200上运行良好，我可以卷曲它。

我的logstash.config看起来像这样：

http.host: "0.0.0.0"
xpack.monitoring.elasticsearch.url: http://localhost:9200

我的logstash-sample.conf：

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
  beats {
    port => 5044
  }
}

output {
  elasticsearch {
    hosts => ["http://localhost:9200"]
    index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
    #user => "elastic"
    #password => "changeme"
  }
}

我用来启动容器。

docker run                         --name logstash             -p 5044:5044                                      -e "discovery.type=single-node"  docker.elastic.co/logstash/logstash:6.4.2

但是我得到以下带有错误的日志：

而且这种情况一直持续下去。 我将非常感谢您的帮助，并有义务。 谢谢。

正如@Val注释所注意到的，本地主机位于容器内，它是容器，而不是您的HOST计算机。

如果Docker Compose适合您，则可以尝试'sebp/elk' Docker镜像，其中包含ElasticSearch，LogStash和Kibana。并使用此示例撰写文件

docker-compose.yml ：

version: "2.4"
services:
  elk:
    image: sebp/elk
    ports:
      - "5601:5601"
      - "9200:9200"
      - "5044:5044"
  1. 安装Docker-Compose
  2. 将示例'docker-compose.yml'保存在文件夹中
  3. 在同一文件夹中运行：$ docker-compose up

但是，如果要更改配置，则应该：

  1. 以该映像为基础创建自己的Dockerfile，并覆盖所需的conf文件
  2. 用户Docker Compose卷，可通过编辑docker-compose.yml而不是使用Dockerfile创建新的Docker映像来覆盖单个文件

替代：

  1. 在容器配置中使用您的私有本地LAN ip，而不是“ localhost”，以便容器可以访问它。
  2. 使用这两个容器化系统，并且在“ docker run”上使用相同的网络，设置主机名，并在配置中使用这些主机名。
  3. 为每个系统（弹性和LogStash）使用Docker Compose一项服务，并在配置中使用服务名称（因为Docker Compose默认将服务名称用作主机名）
  4. 使用Docker Compose的原始建议，通过sebp / elk Docker Image提供一项服务，因此所有内容都在同一容器中，并且可以保留localhost conf

请记住，每个备选方案可能都有不同的方法来自定义配置。

我认为问题的线索是此错误消息：

[2018-11-02T15:30:52,865][ERROR][logstash.inputs.metrics  ] X-Pack is installed on Logstash but not on Elasticsearch. Please install X-Pack on Elasticsearch to use the monitoring feature. Other features may be available.

您似乎已在Logstash上安装了X-Pack，但未在Elasticsearch节点上安装。尝试一下，然后重新运行Logstash。
