当我在Windows上运行时，此文件运行良好，但是现在我必须在Linux上重新启动项目，但我不知道该怎么办？在下面查看logstash.conf。
cammand：./logstash -f longstash.conf
input {
jdbc {
jdbc_connection_string =>"jdbc:mysql://localhost:3306/test"
jdbc_user =>"root"
jdbc_password =>"password"
jdbc_driver_library =>"/usr/share/java/mysql-connector-java-5.1.45.jar"
jdbc_driver_class =>"com.mysql.jdbc.Driver"
schedule =>"* * * * *"
statement =>"SELECT * FROM Pro WHERE last_modificate >:sql_last_value"
use_column_value =>true
tracking_column =>last_modificate
}
}
output {
elasticsearch {
hosts =>"localhost:9200"
action=>update
document_id =>"%{id}"
doc_as_upsert =>true
index =>"blog"
document_type =>"pro"
}
}
然后看到错误：

由于错误是不言自明的。

请仔细检查配置凭据。在Linux上，必须转到/ usr / share / logstash目录，然后运行以下命令。
sudo bin/logstash -f /etc/logstash/conf.d/yourfilename.conf
