docker安装ElasticSearch8.1.0错误curl: (52) Empty reply from server的处理方法_elasticsearch curl: (52) empty reply from server

启动：设置端口，配置内存大小

docker run -d --name ES8 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:8.1.0

遇到的坑：

[root@lysw vm]# curl 127.0.0.1:9200
curl: (52) Empty reply from server

解决方法：

​
##进入容器，修改elasticsearch.yml
[root@lysw config]# docker exec -it d31948cd75ef /bin/bash
elasticsearch@d31948cd75ef:~$ vi config/elasticsearch.yml
将其中的
xpack.security.enabled: true
#修改为，其他不要动，否则ES容器直接启动不了了
xpack.security.enabled: false
问题：使用外部配置文件，暂时无法启动

出现：

[root@lysw ~]# curl localhost:9200
{
  "name" : "b34422a82861",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "D-HStdfcQd-QWHXLvwqZIA",
  "version" : {
    "number" : "8.1.0",
    "build_flavor" : "default",
    "build_type" : "docker",
    "build_hash" : "3700f7679f7d95e36da0b43762189bab189bc53a",
    "build_date" : "2022-03-03T14:20:00.690422633Z",
    "build_snapshot" : false,
    "lucene_version" : "9.0.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}
[root@lysw ~]# 
成功！
