http-basic插件

是对elasticsearch的http请求做验证的，所有不在白名单的客户机发起的http请求操作都需要用户名密码认证。

如下配置：

vi elasticsearch.yml

http.basic.enabled: true
http.basic.user: "klpeng"
http.basic.password: "www.ligphp.com"
http.basic.ipwhitelist: ["localhost", "127.0.0.1"]
http.basic.trusted_proxy_chains: []
http.basic.log: false
http.basic.xforward: ""
