[resolved] Create a new connection to mysql using SSL

Anonymous — Sat, 16 Nov 2024 10:11:44 GMT

Hello,
I need to access a mysql database secured with SSL certificates.
I have the certificates on my dektop, and I was able to access the database using Mysql Workbench.
How should I configure the mysql Db connection in the Metadata ?
I tried to do it as described in this post : , with adding something like that in the additionnal parameters :
noDatetimeStringSync=true&verifyServerCertificate=true&useSSL=true&requireSSL=true&ssl_ca=C:/Users/Desktop/SQL Dev/ca-cert.pem&ssl_key=C:/Users/Desktop/SQL Dev/client-key.pem&ssl_cert=C:/Users/Desktop/SQL Dev/client-cert.pem
But I get this error :

The last packet successfully received from the server was 45 milliseconds ago.  The last packet sent successfully to the server was 44 milliseconds ago.

I wasn't able to find anything in the Talend documentation or in the help section...
Thank you,

I got it :
https://dev.mysql.com/doc/connector-j/5.1/en/connector-j-reference-using-ssl.html
The additional parameters only need the useSSL=true option. And the java keystore must be updated as described in the url above.
