Question

以下是教程中的测试命令：

<object data="{{document}}" type="application/pdf" style="width:100%; height:400px" />

以下是错误。

./logstash -e 'input { stdin { } } output { stdout {} }'

对于错误消息部分说：

Could not find log4j2 configuration at path //usr/share/logstash/config/log4j2.properties. Using default config which logs to console

该目录由logstash拥有和写入。

有人可以建议任何解决方案吗？

您必须在sudo模式下启动logstash。那是

host@host:~$ sudo su
root@host:/home/host# cd /usr/share/logstash
root@host:/usr/share/logstash# ./bin/logstash -e 'input { stdin { } } output { stdout {} }'

异常消息告诉您logstash找不到configure属性，因此您应该在命令中添加一个标志来告诉logstash configure属性。另一个例外是logstash无法写入/ usr / share / logstash / data，您应该使用'sudo'来启动此命令，或者您可以将/ usr / share / logstash / data的写入权限添加到您的帐户。

logstash版本：5.5.2

os版本：ubuntu 16.04

启动logstash作为流程的命令：

sudo bin/logstash -e 'input { stdin { } } output { stdout {} }' --path.settings=/etc/logstash

ps：我通过apt install the document of install logstash

安装logstash

Answer 3

您打算以logstash用户身份运行它，而不是root或任何其他用户 - 这就是logstash用户拥有它的原因。因此，请改用以下内容：

sudo -Hu logstash /usr/share/logstash/bin/logstash -e 'input { stdin { } } output { stdout {} }'

此处的主要部分是以logstash用户身份运行您的命令：

sudo -Hu logstash <command you want to run>

Answer 4

您可以创建logstash-data目录，并使用--path.data logstash-data将当前目录中的logstash-data用作logstash数据目录。

我无法在我的机器上启动logstash。里面有错误信息
