jdbc - Logstash 'com.mysql.jdbc.Driver' 未加载

Question

我有问题 jdbc_driver_library .我正在使用 ELK_VERSION = 6.4.2我将 Docker 用于 ELK。
当我运行时:

/opt/logstash# bin/logstash -f /etc/logstash/conf.d/mysql.conf

我收到一个错误:

error: com.mysql.jdbc.Driver not loaded. Are you sure you've included the correct jdbc driver in :jdbc_driver_library?

驱动路径:

root@xxxxxxx:/etc/logstash/conectors# ls
mysql-connector-java-8.0.12.jar 
root@xxxxxxxxxx:/etc/logstash/conectors#

mysql.conf:

input {
  jdbc {
    jdbc_driver_library => "/etc/logstash/conectors/mysql-connector-java-8.0.12.jar"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://localhost:3306/mydb"
    jdbc_user => "demouser"
    jdbc_password => "demopassword"
    statement => "SELECT id,name,city from ads"
  }
}

output {
    stdout { codec => rubydebug }
    elasticsearch {
        index => 'test'
        document_type => 'tes'
        document_id => '%{id}'
        hosts => ['http://localhost:9200']
    }
}

整个错误:

当我构建图像并使用 docker run 时，我收到另一个错误:

[2018-11-10T10:32:54,509][ERROR][org.logstash.Logstash    ] java.lang.IllegalStateException: Logstash stopped processing because of an error: (SystemExit) exit

当我使用 PostgreSQL 时，同样的问题。
配置文件

input {
   jdbc {
     type => 'test'
     jdbc_driver_library => '/etc/logstash/postgresql-9.1-901-1.jdbc4.jar'
     jdbc_driver_class => 'org.postgresql.Driver'
     jdbc_connection_string => 'jdbc:postgresql://localhost:5432/mytestdb'
     jdbc_user => 'postgres'
     jdbc_password => 'xxxxxx'
     jdbc_page_size => '50000'
     statement => 'SELECT id, name, city FROM ads'
   }
 }

然后我运行:

/opt/logstash# bin/logstash -f /etc/logstash/conf.d/psql.conf

错误:

error: org.postgresql.Driver not loaded. Are you sure you've included the correct jdbc driver in :jdbc_driver_library?

Answer 1

我遇到了同样的问题，下面的解决方案解决了我的问题。

对于 logstash 6.2.x 及更高版本，在下面添加所需的驱动程序:

logstash_install_dir/logstash-core/lib/jars/
并且不要在配置文件中提供任何驱动程序路径。
