Docker实现安装ELK(单节点)

作者：wang18057

这篇文章主要介绍了Docker实现安装ELK(单节点),具有很好的参考价值,希望对大家有所帮助,如有错误或未考虑完全的地方,望不吝赐教

Docker 安装ELK(单节点)

创建docker网络

docker network create -d bridge elastic

拉取elasticsearch 8.4.3版本

docker pull docker.elastic.co/elasticsearch/elasticsearch:8.4.3
也可能是这个
docker pull elasticsearch:8.4.3

第一次执行docker脚本

docker run -it \
-p 9200:9200 \
-p 9300:9300 \
--name elasticsearch \
--net elastic \
-e ES_JAVA_OPTS="-Xms1g -Xmx1g" \
-e "discovery.type=single-node" \
-e LANG=C.UTF-8 \
-e LC_ALL=C.UTF-8 \
elasticsearch:8.4.3

注意第一次执行脚本不要加-d这个参数，否则看不到服务首次运行时生成的随机密码和随机 enrollment token

拷贝日志中的以下内容，备用

✅ Elasticsearch security features have been automatically configured!
✅ Authentication is enabled and cluster connections are encrypted.

ℹ️  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  =HjjCu=tj1orDTLJbWPv

ℹ️  HTTP CA certificate SHA-256 fingerprint:
  9204867e59a004b04c44a98d93c4609937ce3f14175a3eed7afa98ee31bbd4c2

ℹ️  Configure Kibana to use this cluster:
• Run Kibana and click the configuration link in the terminal when Kibana starts.
• Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):
  eyJ2ZXIiOiI4LjQuMyIsImFkciI6WyIxNzIuMjIuMC4yOjkyMDAiXSwiZmdyIjoiOTIwNDg2N2U1OWEwMDRiMDRjNDRhOThkOTNjNDYwOTkzN2NlM2YxNDE3NWEzZWVkN2FmYTk4ZWUzMWJiZDRjMiIsImtleSI6Img0bGNvSkFCYkJnR1BQQXRtb3VZOnpCcjZQMUtZVFhHb1VDS2paazRHRHcifQ==

ℹ️ Configure other nodes to join this cluster:
• Copy the following enrollment token and start new Elasticsearch nodes with `bin/elasticsearch --enrollment-token <token>` (valid for the next 30 minutes):
  eyJ2ZXIiOiI4LjQuMyIsImFkciI6WyIxNzIuMjIuMC4yOjkyMDAiXSwiZmdyIjoiOTIwNDg2N2U1OWEwMDRiMDRjNDRhOThkOTNjNDYwOTkzN2NlM2YxNDE3NWEzZWVkN2FmYTk4ZWUzMWJiZDRjMiIsImtleSI6ImhZbGNvSkFCYkJnR1BQQXRtb3VLOjRZWlFkN1JIUk5PcVJqZTlsX2p6LXcifQ==

  If you're running in Docker, copy the enrollment token and run:
  `docker run -e "ENROLLMENT_TOKEN=<token>" docker.elastic.co/elasticsearch/elasticsearch:8.4.3`

创建相应目录并复制配置文件到主机

mkdir -p apps/elk8.4.3/elasticsearch
# 这个cp命令是在 /home/ubuntu目录下执行的
docker cp elasticsearch:/usr/share/elasticsearch/config apps/elk8.4.3/elasticsearch/

docker cp elasticsearch:/usr/share/elasticsearch/data apps/elk8.4.3/elasticsearch/

docker cp elasticsearch:/usr/share/elasticsearch/plugins apps/elk8.4.3/elasticsearch/

docker cp elasticsearch:/usr/share/elasticsearch/logs apps/elk8.4.3/elasticsearch/

删除容器

docker rm -f elasticsearch

修改apps/elk8.4.3/elasticsearch/config/elasticsearch.yml

vim apps/elk8.4.3/elasticsearch/config/elasticsearch.yml

添加

  • 增加：xpack.monitoring.collection.enabled: true
  • 说明：添加这个配置以后在kibana中才会显示联机状态，否则会显示脱机状态

启动elasticsearch

docker run -it \
-d \
-p 9200:9200 \
-p 9300:9300 \
--name elasticsearch \
--net elastic \
-e ES_JAVA_OPTS="-Xms1g -Xmx1g" \
-e "discovery.type=single-node" \
-e LANG=C.UTF-8 \
-e LC_ALL=C.UTF-8 \
-v /home/ubuntu/apps/elk8.4.3/elasticsearch/config:/usr/share/elasticsearch/config \
-v /home/ubuntu/apps/elk8.4.3/elasticsearch/data:/usr/share/elasticsearch/data \
-v /home/ubuntu/apps/elk8.4.3/elasticsearch/plugins:/usr/share/elasticsearch/plugins \
-v /home/ubuntu/apps/elk8.4.3/elasticsearch/logs:/usr/share/elasticsearch/logs \
elasticsearch:8.4.3

启动验证

https://xxxxx:9200/
用户名:elastic
密码在第一次启动时保存下来的信息中查找

Kibana

安装Kibana

docker pull kibana:8.4.3

启动Kibana

docker run -it \
--restart=always \
--log-driver json-file \
--log-opt max-size=100m \
--log-opt max-file=2 \
--name kibana \
-p 5601:5601 \
--net elastic \
kibana:8.4.3

初始化Kibana鉴权凭证

http://xxxx:5601/?code=878708

注意：

在textarea中填入之前elasticsearch生成的相关信息,注意这个token只有30分钟的有效期，如果过期了只能进入容器重置token,进入容器执行

/bin/elasticsearch-create-enrollment-token -s kibana --url "https://127.0.0.1:9200"

kibana验证

将服务端的log中输出的验证码，输入到浏览器中，我这里是628503

创建kibana目录并copy相关配置信息

mkdir apps/elk8.4.3/kibana

# 这个cp命令是在 /home/ubuntu目录下执行的
docker cp kibana:/usr/share/kibana/config apps/elk8.4.3/kibana/


docker cp kibana:/usr/share/kibana/data apps/elk8.4.3/kibana/

docker cp kibana:/usr/share/kibana/plugins apps/elk8.4.3/kibana/

docker cp kibana:/usr/share/kibana/logs apps/elk8.4.3/kibana/

sudo chown -R 1000:1000 apps/elk8.4.3/kibana

修改apps/elk8.4.3/kibana/config/kibana.yml
