Logstash 配置错误 - 未设置 jdbc_driver_library

Question

我正在使用 Logstash 将数据从 Microsoft SQL Server 数据库移动到 ElasticSearch。当我尝试运行logstash 时，我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：

  Error: com.microsoft.sqlserver.jdbc.SQLServerDriver not loaded. :jdbc_driver_library is not set, are you sure you included
                    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 配置是：

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，不知道为什么我总是收到错误，为什么logstash找不到它。

我也尝试过运行（如下）

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

注：我取出了一些数据，ip，dbname，username等

这已经成为logstash-filter-jdbc_static 的问题有一段时间了。您需要将 .jar 移动到 /logstash-core/lib/jars/ 目录。并将配置中的 .jar 位置指定为“”。
