LogStash 错误：Logstash could not be started because there is already another instance using the config

LogStash 错误信息： Logstash could not be started because there is already another instance using the configured data directory.  If you wish to run multiple instances, you must change the "path.data" setting. 

解决方法：

切换到logshash 安装目录：

比如我的目录在： /usr/share/logstash/logstash-6.2.4 下，

找到data目录，然后进入cd  data 

查看 ls -lah 看到那个.lock 的文件删除即可

删除命令：rm  -rf  .lock  然后从新启动 即可
