elasticsearch - 我无法在我的机器上启动 logstash。里面的错误信息

Question

以下是教程中的测试命令:

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

以下是错误。

WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path //usr/share/logstash/config/log4j2.properties. Using default config which logs to console

至于错误消息部分说:

Path "/usr/share/logstash/data" must be a writable directory. It is not writable.

该目录由 logstash 拥有和写入。

任何人都可以提出任何解决方案吗？

您必须以 sudo 模式启动 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 {} }'
