【ES】elasticsearch8.3.3

这里仅实践操作并根据实际问题进行记录笔记。

运行 ES8

我们需要在自己的电脑上安装好 Docker Desktop。接着我们运行如下的命令：出现两个异常，一个是需要使用winpty因为我使用win的docker desktop，另外一个问题是docker启动elasticsearchERROR: Elasticsearch did not exit normally - check the logs at xxx。解决办法：在运行命令中添加 -e "discovery.type=single-node"。最终运行命令

$ docker network create elastic
$ docker pull docker.elastic.co/elasticsearch/elasticsearch:8.3.3
winpty docker run  -e ES_JAVA_OPTS="-Xms1024m -Xmx1024m" -e "discovery.type=single-node" --name es-node01 --net elastic -p 9200:9200 -p 9300:9300 -it docker.elastic.co/elasticsearch/elasticsearch:8.3.3$ docker logs es-node01 -f --tail 1000$ docker pull docker.elastic.co/kibana/kibana:8.3.3
$ winpty docker run --name kib-01 --net elastic -p 5601:5601 docker.elastic.co/kibana/kibana:8.3.3

安装 IK

sh-5.0$ cd /usr/share/elasticsearch/
sh-5.0$ ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v8.3.3/elasticsearch-analysis-ik-8.3.3.zip^C
sh-5.0$ pwd
/usr/share/elasticsearch
sh-5.0$ ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v8.3.3/elasticsearch-analysis-ik-8.3.3.zip

analysis-ik上面的命令显示我们的 IK 已经安装成功了。
这个时候需要我们重新启动一下我们的 Elasticsearch，以便这个 plugin 能装被加载。
