1，keytool导入elasticsearch的证书。

keytool -importcert -file http_ca.crt -alias esca -cacerts -storepass changeit -noprompt

2，修改cerebro配置文件/etc/cerebro/application.conf，增加elasticsearch用户名信息。

hosts = [
 {
    host = "https://10.0.0.1:9200"
    name = "elasticsearch"
    auth = {
      username = "elastic"
      password = "123456"
    }
  }
]
