Docker方式安装
<h3>1，取一个镜像，然后运行一下</h3>
<p><code>docker pull elasticsearch:7.17.5</code></p>
<p>如果提示镜像无法下载，试试修改一下下面的文件</p>
<p>vim /etc/docker/daemon.json</p>
<p>> {
"registry-mirrors": [
"<a href="https://docker.1panelproxy.com"">https://docker.1panelproxy.com"</a>;,
"<a href="https://2a6bf1988cb6428c877f723ec7530dbc.mirror.swr.myhuaweicloud.com"">https://2a6bf1988cb6428c877f723ec7530dbc.mirror.swr.myhuaweicloud.com"</a>;,

}</p>
<p><code>systemctl daemon-reload</code></p>
<p><code>systemctl restart docker</code></p>
<p><code>docker pull elasticsearch:7.17.5</code></p>
<h3>2、创建对应的挂载目录</h3>
<p>> mkdir -p /cf/data/elasticsearch/config
mkdir -p /cf/data/elasticsearch/data
mkdir -p /cf/data/elasticsearch/plugins</p>
<h3>3、设置对应的权限</h3>
<p><code>chmod 777 /cf/data/elasticsearch/data</code></p>
<h3>4、创建配置文件，并配置内容</h3>
<p>> touch /cf/data/elasticsearch/config/elasticsearch.yml
vim /cf/data/elasticsearch/config/elasticsearch.yml</p>
<h3>5、配置文件内容如下：</h3>
<p>network.host: 0.0.0.0
http.host: 0.0.0.0
cluster.name: "cfzh_cluster"
http.cors.enabled: true
http.cors.allow-origin: "*"</p>
<h3>6、安装ik分词器</h3>
<p>找到对应版本的ik分词器进行下载，例如我这里是 7.17.5，我下载地址为：<a href="https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v7.17.5">https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v7.17.5</a>
如果你的版本不是这个版本，可以到这去选：<a href="https://github.com/medcl/elasticsearch-analysis-ik/releases">https://github.com/medcl/elasticsearch-analysis-ik/releases</a>
下载之后得到一个zip压缩包，</p>
<p>创建一个目录:</p>
<p><code>mkdir -p /cf/data/elasticsearch/plugins/ik</code></p>
<p>将压缩包上传到该 <code>/cf/data/elasticsearch/plugins/ik</code> 该目录下，然后解压该压缩包:</p>
<p><code>unzip elasticsearch-analysis-ik-7.17.5.zip</code></p>
<h3>7、最后启动容器</h3>
<p><code>docker run --name elasticsearch_a -p 9200:9200 -p 9300:9300 -e &quot;discovery.type=single-node&quot; -e ES_JAVA_OPTS=&quot;-Xms84m -Xmx512m&quot; -v /cf/data/elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /cf/data/elasticsearch/data:/usr/share/elasticsearch/data -v /cf/data/elasticsearch/plugins:/usr/share/elasticsearch/plugins -d elasticsearch:7.17.5</code></p>
<h3>8、配置es必须使用 用户名和密码访问</h3>
<p><code>sudo docker ps --format &#039;{{.Names}}&#039;</code>
使用上面显示的名称，执行 <code>sudo docker exec -it 这里换为上面显示的名称 bash</code></p>
<p><code>cd /usr/share/elasticsearch/config</code></p>
<p><code>vim /cf/data/elasticsearch/config/elasticsearch.yml</code></p>
<p>加入下面两行</p>
<p>> xpack.security.enabled: true
xpack.license.self_generated.type: basic</p>
<p><code>exit</code></p>
<p><code>sudo docker restart elasticsearch</code></p>
<p>再次进入 ElasticSearch 容器内部
<code>sudo docker exec -it 这里换为上面显示的名称 bash</code></p>
<p><code>./bin/elasticsearch-setup-passwords interactive</code></p>
<h3>9、访问一下Elasticsearch的地址（<code>注意，IP根据你自己的实际情况，这里的 192.168.0.10只是示例</code>）</h3>
