Hello to all

I am trying to set up TLS in percona-server 5.6 (on debian jessie).

I have created my root CA and key pair and set it up in my.cnf (under the ‘mysqld’ section)

ssl-ca=/etc/ssl/certs/ca-certificates.crt  
ssl-cert=/etc/mysql/certs/db.investme.com.crt  
ssl-key=/etc/mysql/certs/db.investme.com.key

I gave mysql user and group permissions to them:

chown -R mysql:mysql /etc/mysql/certs/

But I still get this in the error log:

2016-02-08 08:47:27 12930 [Note] RSA private key file not found: /var/lib/mysql//private\_key.pem. Some authentication plugins will not work.  
2016-02-08 08:47:27 12930 [Note] RSA public key file not found: /var/lib/mysql//public\_key.pem. Some authentication plugins will not work.

I tried to create symlinks in /var/lib/mysql but then the startup mysql script would freeze.

Any idea? Is this something I should worry about?
