ELK - 無法連線至ES

 設定完TLS 發現只能本機用IP連,使用127.0.0.1及localhost無法連線

其他主機也都無法連線

 Comment

curl https://localhost:9200
curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to localhost:9200

在 elasticsearch_audit 發現

{"type":"audit", "timestamp":"2022-01-20T12:57:57,621+0800", "node.id":"tUCQb6ADSLaZHr4VU8w7WA", "event.type":"ip_filter", "event.action":"connection_denied", "origin.type":"rest", "origin.address":"127.0.0.1", "transport.profile":".http", "rule":"deny _all"}

原來是之前設定到，但沒啟用security所以沒生效

curl "https://IP:9200/_cluster/settings?pretty"
{
  "persistent" : {
    "cluster" : {
      "max_shards_per_node" : "2000"
    },
    "xpack" : {
      "monitoring" : {
        "collection" : {
          "enabled" : "true"
        }
      },
      "security" : {
        "http" : {
          "filter" : {
            "allow" : "IP",
            "deny" : "_all",
            "enabled" : "true"
          }
        },
        "transport" : {
          "filter" : {
            "allow" : "IP",
            "deny" : "_all",
            "enabled" : "false"
          }
        }
      }
    }
  },
  "transient" : { }
}

把它disable就沒事了!!

curl -X PUT "https://IP:9200/_cluster/settings"  -H 'Content-Type: application/json' -d'
{
  "persistent": {
    "xpack.security.http.filter.enabled": false
  }
}

EZChart Data

意外看到EZChart臺灣股市歷史資料
寫一下程式把資料爬出來

        static void Main(string[] args)
        {
            var file = File.OpenRead(@"C:\Program Files (x86)\ezChart\Data\0050.dat");
            var size = file.Length;
            using (var br = new BinaryReader(file))
            {
                long readsize = 0;
                while (size > readsize)
                {
                    int date = br.ReadInt32();
                    decimal opening = (decimal)br.ReadInt32() / 100;
                    decimal highest = (decimal)br.ReadInt32() / 100;
                    decimal lowest = (decimal)br.ReadInt32() / 100;
                    decimal closing = (decimal)br.ReadInt32() / 100;
                    int volume = br.ReadInt32();
                    Console.WriteLine($"date: {date},opening: {opening}, highest: {highest}, lowest: {lowest}, closing: {closing}, volume: {volume}");
                    readsize += sizeof(Int32) * 6;
                }
            }

        }
