关于#elasticsearch#的问题，如何解决？

elasticsearch7 集成 searchGuard 之后，无法通过浏览器访问问题

  • es版本7.3.2
  • searchGuard版本7.3.2-37.0.0
    按照教程部署完毕后，执行tools里面的install_demo_configuration.sh,未更改原始代码，可以部署和启动，单用浏览器访问后就提示如下问题：

```bash

    • 这篇博客: elasticsearch的集群部署（含资源）中的 解决启动问题二：普通用户启动线程数限制 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:

      问题错误信息描述

      max number of threads [1024] for user [es] likely too low, 
increase to at least [4096]

      修改普通用户可以创建的最大线程数
      max number of threads [1024] for user [es] likely too low, increase to at least [4096]
      原因：无法创建本地线程问题,用户最大可创建线程数太小
      解决方案：修改90-nproc.conf 配置文件。

      三台机器使用es用户执行以下命令修改配置文件

      sudo vi /etc/security/limits.d/90-nproc.conf

      找到如下内容：

      * soft nproc 1024

      #修改为

      * soft nproc 4096

    如果你已经解决了该问题, 非常希望你能够分享一下解决方案, 写成博客, 将相关链接放在评论区, 以帮助更多的人 ^-^
