1、将ES的账号:密码通过Base64加密

假设账号密码如下：

• 账号：elastic
• 密码：elastic@huayunworld.com

echo -n 'elastic:elastic@huayunworld.com' | base64
ZWxhc3RpYzplbGFzdGljQGh1YXl1bndvcmxkLmNvbQ==

2、在 Nginx 配置中传递认证信息

location /es/ {
    proxy_pass http://es.huayunworld.com:9200/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header Authorization "Basic ZWxhc3RpYzplbGFzdGljQGh1YXl1bndvcmxkLmNvbQ=="; # 认证信息,如何需要认证把此项注释掉.
    proxy_redirect off;
}

3、测试

curl http://127.0.0.1/es/
{
  "name" : "es1",
  "cluster_name" : "docker-cluster",
  "cluster_uuid" : "FgishdSnQF2iPmanRsmfEw",

    "build_type" : "docker",
    "build_hash" : "f65e9d338dc1d07b642e14a27f338990148ee5b6",
    "build_date" : "2022-08-23T11:08:48.893373482Z",
    "build_snapshot" : false,
    "lucene_version" : "8.11.1",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}
