mac下docker 安装 ES的详细过程

一. docker 安装 ES

1. 下载镜像

docker pull elastcisearch:8.7.1

2. 启动镜像

docker run -d –name elasticsearch -p 9200:9200 -p 9300:9300 -e \”discovery.type=single-node\” -e ES_JAVA_OPTS=\”-Xms256m -Xmx256m\” elasticsearch:8.7.1

参数说明

-d后台启动
–name起别名即：NAMES
-p 9200:9200将端口映射出来
elasticsearch的9200端口是供外部访问使用；
9300端口是供内部访问使用集群间通讯
-e "discovery.type=single-node"单节点启动
-e ES_JAVA_OPTS="-Xms256m -Xmx256m"限制内存大小

3.访问es

curl http://localhost:9200
curl: (52) Empty reply from server

4.进入docker

docker exec -it 0a9bb3fa153d bash

docker exec在运行的容器中执行命令

-i :即使没有附加也保持STDIN 打开
-t :分配一个伪终端

找到es配置文件位置

/usr/share/elasticsearch/config/elasticsearch.yml

将docker容器中的配置文件拷贝到本地文件

docker cp 0a9bb3fa153d:/usr/share/elasticsearch/config/elasticsearch.yml /usr/local/share/elasticsearch/elasticsearch.yml

将 xpack.security.enable: true 改为 xpack.security.enable: false

再将修改后的配置文件拷贝回docker中

docker cp /usr/local/share/elasticsearch/elasticsearch.yml 0a9bb3fa153d:/usr/share/elasticsearch/config/elasticsearch.yml

重启docker

docker stop 0a9bb3fa153d
docker start 0a9bb3fa153d
curl localhost:9200
{
\”name\” : \”0a9bb3fa153d\”,
\”cluster_name\” : \”docker-cluster\”,
\”cluster_uuid\” : \”8hyCPOJESfKParQcDmGgtw\”,
\”version\” : {
\”number\” : \”8.7.1\”,
\”build_flavor\” : \”default\”,
\”build_type\” : \”docker\”,
\”build_hash\” : \”f229ed3f893a515d590d0f39b05f68913e2d9b53\”,
\”build_date\” : \”2023-04-27T04:33:42.127815583Z\”,
\”build_snapshot\” : false,
\”lucene_version\” : \”9.5.0\”,
\”minimum_wire_compatibility_version\” : \”7.17.0\”,
\”minimum_index_compatibility_version\” : \”7.0.0\”
},
\”tagline\” : \”You Know, for Search\”
}

5. 决定将重新建立docker镜像，本机创建文件夹，并将docker容器中的配置文件等信息拷贝出来，重新起容器并挂载外部文件夹

mkdir -p /Users/chenpeng/share/elasticsearch/{config,data,logs,plugins}
docker cp 0a9bb3fa153d:/usr/share/elasticsearch/config /Users/chenpeng/share/elasticsearch
docker cp 0a9bb3fa153d:/usr/share/elasticsearch/logs /Users/chenpeng/share/elasticsearch
docker cp 0a9bb3fa153d:/usr/share/elasticsearch/data /Users/chenpeng/share/elasticsearch
docker cp 0a9bb3fa153d:/usr/share/elasticsearch/plugins /Users/chenpeng/share/elasticsearch

注意mac系统不要把文件夹放在系统文件夹中，容易没有权限。我之前放在宿主的/usr/share/elasticsearch目录下，不管如何更改权限，docker容器都没有权限访问。

确保有以下几个配置，原有的配置可以不改动

cluster.name: \”docker-cluster\”
network.hosts:0.0.0.0
# 跨域
http.cors.allow-origin: \”*\”
http.cors.enabled: true
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

删除临时容器

docker stop 0a9bb3fa153d
docker rm 0a9bb3fa153d

重新起容器并挂起文件夹

docker run -d –name elasticsearch \\
-p 9200:9200 \\
-p 9300:9300 \\
-e \”discovery.type=single-node\” \\
-e ES_JAVA_OPTS=\”-Xms512m -Xmx512m\” \\
-e TAKE_FILE_OWNERSHIP=true \\
-v /Users/chenpeng/share/elasticsearch/logs:/usr/share/elasticsearch/logs \\
-v /Users/chenpeng/share/elasticsearch/data:/usr/share/elasticsearch/data \\
-v /Users/chenpeng/share/elasticsearch/plugins:/usr/share/elasticsearch/plugins \\
-v /Users/chenpeng/share/elasticsearch/config:/usr/share/elasticsearch/config \\
elasticsearch:8.7.1

访问curl localhost:9200

curl localhost:9200
{
\”name\” : \”61c83e2b4f2b\”,
\”cluster_name\” : \”docker-cluster\”,
\”cluster_uuid\” : \”Wp0M92PxQYyYbJVL_2IKmA\”,
\”version\” : {
\”number\” : \”8.7.1\”,
\”build_flavor\” : \”default\”,
\”build_type\” : \”docker\”,
\”build_hash\” : \”f229ed3f893a515d590d0f39b05f68913e2d9b53\”,
\”build_date\” : \”2023-04-27T04:33:42.127815583Z\”,
\”build_snapshot\” : false,
\”lucene_version\” : \”9.5.0\”,
\”minimum_wire_compatibility_version\” : \”7.17.0\”,
\”minimum_index_compatibility_version\” : \”7.0.0\”
},
\”tagline\” : \”You Know, for Search\”
}
