我该如何解决这个问题并让 Elastisearch 正常工作？

答案1

curl您的命令返回 Squid 错误消息这一事实表明发生了以下两件事之一：

  1. Squid 而不是 elasticsearch 监听端口 9200。您可以使用 sudo netstat -tnlp | grep :9200或检查sudo ss -tnlp | grep :9200哪个进程监听端口 9200

  2. localhost或者，您已使用 http 代理设置配置了 curl ，但未将127.0.0.1和系统自己的 IP 地址和主机名添加到代理排除列表中。
    除非您正在调试代理服务器，否则您不会使用代理来连接您可以直接连接的服务。
    将-v开关添加到您的 curl 命令中，例如参见此回答举例来说，curl 使用代理服务器。
    设置export no_proxy=internal.example.com,127.0.0.1,localhost以防止 curl 使用代理向这些主机发出请求。
