安装 Elasticsearch elasticsearch-8.11.1

下载

访问 Elasticsearch 下载页面

解压下载的压缩文件到你选择的目录。

运行

进入 Elasticsearch 目录，运行 bin/elasticsearch.bat 启动 Elasticsearch。

验证

elaasticsearch的默认访问路径是localhost:9200，我们打开浏览器直接访问即可。

如果访问不了也没关系，我们可以先修改配置文件之后再进行访问。

注意：8.4.3我测试的无法直接打开默认网址，需要先进行配置（原因是：ES8默认开启了ssl认证，导致无法访问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下开启了安全认证，虽然started成功，但访问http://localhost:9200/失败（https://blog.csdn.net/zhangphil/article/details/124476717）

修改 elasticsearch.yml

原来是这样：

# Enable security features
xpack.security.enabled: truexpack.security.enrollment.enabled: true# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:enabled: truekeystore.path: certs/http.p12# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:enabled: trueverification_mode: certificatekeystore.path: certs/transport.p12truststore.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

我们把几个安全的暂时都关闭掉。

# Enable security features
xpack.security.enabled: falsexpack.security.enrollment.enabled: false# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:enabled: falsekeystore.path: certs/http.p12# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:enabled: falseverification_mode: certificatekeystore.path: certs/transport.p12truststore.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

重新启动 es。当然这只是为了演示关闭的，实际应用还是要注意安全问题。

PS: 我这里在启动日志中没有找到密码，按理说是有一个初始化密码的。

验证成功

此时访问 http://localhost:9200/
