Hi All,

I don't understand what's wrong in below conf file.

input {  
jdbc {  
jdbc\_driver\_library =\> "/usr/share/logstash/myjars/mysql-connector-java-8.0.11.jar"  
jdbc\_driver\_class =\> "com.mysql.cj.jdbc.Driver"  
jdbc\_connection\_string =\> "jdbc:mysql://10.0.1.133:5500/alumini\_factor"  
jdbc\_user =\> "root"  
jdbc\_password =\> "\*\*\*\*\*\*\*\*"  
statement =\> "select \* FROM profile"  
use\_column\_value =\> true  
tracking\_column =\> id  
}  
}

output {  
elasticsearch {  
document\_id =\> "%{id}"  
hosts =\> ["[http://localhost:9200](http://localhost:9200)"]  
index =\> "profiles"  
document\_type =\> "data"  
}  
}

P.S:  
Elasticsearch version 7.0.1  
Logstash version 7.3  
Mysql verion 5.7.26-0ubuntu0.16.04.1

Thanks,  
Manideep

hi @guyboertje

I think it is JDK 8.

Did you try using the "old" driver class `com.mysql.jdbc.Driver`?

Hi @guyboertje

Thanks for the response.

I figured out the error.

As I am new to Linux, I did not understand the Logstash installation process.

i tried installing Logstash using APT given in the Logstash Docs.

Logstash was installed at /usr/share/logstash but the config folder was missing inside the Logstash.  
So, I externally copied the config folder inside the Logstash and tried to run it. It did not work.

Sometime later, i realized that config folder from original installation was in /etc/config.

So, I have two config folders one inside the Logstash and another in /etc/. (I am really not sure if this is the issue.)

Then, I deleted everything and downloaded tat.gz file and extracted to the location /usr/share/.

It now has config folder. I ran the logstash with my conf file and it worked.

Thanks,  
Manideep

In my local windows, I used new driver as the jar is 8.0.1.

Now, in the linux, I used old driver as the jar is 5.1.38.
