Logstash配置错误-未设置jdbc_driver_library

Question

我正在使用Logstash将数据从我的Microsoft SQL Server数据库移至ElasticSearch。 当我尝试运行logstash时，在日志文件中收到以下错误。 我跑：

sudo -Hu logstash /usr/share/logstash/bin/logstash --path.settings=/etc/logstash -t

错误：

  Exception: LogStash::ConfigurationError

                    the proper driver client libraries in your classpath?

我在Ubuntu 18服务器上运行ElasticSearch / Logstash。 我安装了ElasticSearch，Logstash，Java 11，并下载了jdbc并将其放置在与我的logstash配置相同的文件夹中。

我的Logstash配置为：

input {
  jdbc {
    jdbc_driver_library => "/etc/logstash/conf.d/sqljdbc42.jar"
    jdbc_connection_string => "jdbc:sqlserver://[my_ip]:1433;databaseName=[db_name];"
    jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
    jdbc_user => "[username]"
    jdbc_password => "[password]"

    schedule => "0 4 * * * America/New_York"
    statement => "SELECT * FROM [table] WHERE delete_flag = 'N'"
  }
}

output {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "products"
  }
}

我指定了jdbc驱动程序库，但不确定为什么我不断收到错误消息，导致logstash找不到它。

我也试图跑步（下）

sudo bash -c "export CLASSPATH=.:/etc/logstash/conf.d/sqljdbc42.jar"

注意：我取出了一些数据，ip，dbname，用户名等。

一段时间以来，这一直是logstash-filter-jdbc_static的问题。 您需要将.jar移至/ logstash-core / lib / jars /目录。 并在配置中将.jar位置指定为“”。
