Logstash com.mysql.jdbc.Driver未加载

我在使用jdbc_driver_library时遇到问题。

ELK_VERSION = 6.4.2

我将Docker用于麋鹿。

当我跑步时：

$('table tbody').html("");

获取错误：

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

驱动程序路径：

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

mysql.conf：

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

整个错误：

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']
     }

 }

时

错误：

docker run

我使用postgresql时出现相同的问题

psql.conf 

[2018-11-10T10:32:52,935][INFO ][logstash.setting.writabledirectory] Creating directory {:setting=>"path.queue", :path=>"/opt/logstash/data/queue"}

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

然后我跑

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'
   }
 }

错误：

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

4 个答案:

答案 0 :(得分：2)

我遇到了同样的问题，波纹管解决方案解决了我的问题。

对于logstash 6.2.x及更高版本，请在以下位置添加所需的驱动程序：

logstash_install_dir / logstash-core / lib / jars / 并且在配置文件中不提供任何驱动程序路径。

答案 1 :(得分：0)

在您使用的MySQL 8中，JDBC驱动程序从com.mysql.jdbc.Driver重命名为com.mysql.cj.jdbc.Driver（有关详细信息，请参见release notes）。只需更新您的jdbc_driver_class配置，就可以了。

答案 2 :(得分：0)

我解决了这个问题：

首先检查您的Java版本：

root@xxxxxx:/# java -version
openjdk version "1.8.0_181"

如果使用的是1.8，则应使用JDBC42版本。

如果使用的是1.7，则应使用JDBC41版本。

如果您使用的是1.6，则应使用JDBC43版本。

postgres设置：

postgresql-9.4-1203.jdbc42.jar 

 jdbc_driver_library => '/path_to_jar/postgresql-9.4-1203.jdbc42.jar'
 jdbc_driver_class => 'org.postgresql.Driver'

mysql设置：

mysql-connector-java-5.1.46.jar 

 jdbc_driver_library => "//path_to_jar/mysql-connector-java-5.1.46.jar"
 jdbc_driver_class => "com.mysql.jdbc.Driver"

答案 3 :(得分：0)

我有一个类似的问题，但是我有一个不同的设置：我使用的是虚拟机而不是Docker映像。通过在我的Ubuntu服务器虚拟机上安装OpenJDK 8 并将其设置为默认Java版本，解决了该问题。

希望这会有所帮助！

编辑：在此之前，我不得不将root用户的身份验证方法从auth_socket更改为mysql_native_password
