Logstash启动异常: 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.
提示我们已经有一个实例在用data目录了,如果需要配置多个实例,则需要显式的配置path.data的值。

当然我们可以显式的配置path.data的值,让他指向一个新的目录。
也可以将data目录下的.lock文件删除,来解决这个问题。文章来源:https://www.toymoban.com/news/detail-732877.html
