添加logstash“logstash-output-email”失败，重启logstash 启动失败

Question

我尝试使用以下命令安装“logstash-output-email”，但由于防火墙而无法安装，然后我才知道存在无法使用互联网连接的限制。

./logstash-plugin install logstash-output-email

然后我重新启动了 logstash，它开始每 5-10 秒生成新的进程 ID，并且在日志中，它正在寻找 gem 'logstash-output-email'。为什么当插件安装失败并且安装插件与声明/停止logstash应用程序无关时，logstash不起作用。

我确实验证了 logstash 安装文件夹中的哪些文件发生了更改。已在根安装文件夹中创建了一个文件。

来自 /var/log/logstash-stderr.log 文件的错误：

是否可以编辑 Gemfile 以手动删除最后一行并启动 logstash。我只需要启动 logstash 功能，以便我可以进行调试以安装 logstash-output-email 插件。

Answer 1

我建议先尝试删除它：

sudo ./logstash-plugin remove logstash-output-email

当您在防火墙后面时，应通过离线插件进行安装。见：

https://www.elastic.co/guide/en/logstash/current/offline-plugins.html

您需要在可以完全访问互联网的机器上准备离线包，然后您可以安装在防火墙后面，或者没有互联网连接。
