安裝 Elasticsearch elasticsearch-8.11.1

下載

訪問 Elasticsearch 下載頁面

解壓下載的壓縮文件到你選擇的目錄。

運行

進入 Elasticsearch 目錄，運行 bin/elasticsearch.bat 啟動 Elasticsearch。

驗證

elaasticsearch的默認訪問路徑是localhost:9200，我們打開瀏覽器直接訪問即可。

如果訪問不了也沒關(guān)系，我們可以先修改配置文件之后再進行訪問。

注意：8.4.3我測試的無法直接打開默認網(wǎng)址，需要先進行配置（原因是：ES8默認開啟了ssl認證，導(dǎo)致無法訪問9200端口，elasticsearch.yml配置文件添加【xpack.security.enabled: false】即可）（https://zhuanlan.zhihu.com/p/504694531）

Elasticsearch在Windows下開啟了安全認證，雖然started成功，但訪問http://localhost:9200/失?。╤ttps://blog.csdn.net/zhangphil/article/details/124476717）

received plaintext traffic on an encrypted channel, closing connection Netty4TcpChannel

修改 elasticsearch.yml

原來是這樣：

# Enable security features
xpack.security.enabled: true

xpack.security.enrollment.enabled: true

# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
  enabled: true
  keystore.path: certs/http.p12

# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
  enabled: true
  verification_mode: certificate
  keystore.path: certs/transport.p12
  truststore.path: certs/transport.p12
# Create a new cluster with the current node only
# Additional nodes can still join the cluster later
cluster.initial_master_nodes: ["PC-20230404XHIO"]

# Allow HTTP API connections from anywhere
# Connections are encrypted and require user authentication
http.host: 0.0.0.0

我們把幾個安全的暫時都關(guān)閉掉。

# Enable security features
xpack.security.enabled: false

xpack.security.enrollment.enabled: false

# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
  enabled: false
  keystore.path: certs/http.p12

# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
  enabled: false
  verification_mode: certificate
  keystore.path: certs/transport.p12
  truststore.path: certs/transport.p12
# Create a new cluster with the current node only
# Additional nodes can still join the cluster later
cluster.initial_master_nodes: ["PC-20230404XHIO"]

# Allow HTTP API connections from anywhere
# Connections are encrypted and require user authentication
http.host: 0.0.0.0

重新啟動 es。當(dāng)然這只是為了演示關(guān)閉的，實際應(yīng)用還是要注意安全問題。

PS: 我這里在啟動日志中沒有找到密碼，按理說是有一個初始化密碼的。

驗證成功

此時訪問 http://localhost:9200/
