elasticsearch 如何强制停止logstash？

我在服务器上通过SSH启动了logstash，但与Elasticsearch的连接出现错误。当我尝试CTRL+C时，Logstash没有停止，他现在还在跑步。我怎样才能强迫它停止

我的服务器运行CentOS5

试一试

或者如果那不起作用的话

systemctl stop logstash

或者如果这也不起作用

/etc/init.d/logstash stop

或

做

获取所有日志存储过程，并将其作为

kill -9 <process-id>

kill-9

ps -aux|grep logstash

kill -9 <process-id>
