mysql generates the secret key by means of ssl

-- mysql ssl generates the secret key
Is 1 check ssl enabled
mysql > show variables like '%ssl%';

3. Generate the configuration of the certificate through openssl and the secret key on mysql db server
mkdir -p /etc/mysql/newcerts/
cd /etc/mysql/newcerts/
3.1 openssl genrsa 2048 > ca-key.pem
3.2 openssl req -new -x509 -nodes -days 1000 -key ca-key.pem > ca-cert.pem
[root@mysql newcerts]# openssl req -new -x509 -nodes -days 1000 -key ca-key.pem > ca-cert.pem
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [XX]:ch
State or Province Name (full name) []:shh
Locality Name (eg, city) [Default City]:shh
Organization Name (eg, company) [Default Company Ltd]:xx
Organizational Unit Name (eg, section) []:db
Common Name (eg, your name or your server''s hostname) []:mysql.yest.nos
Email Address []:xx@xx.com
3.3 openssl req -newkey rsa:2048 -days 1000 -nodes -keyout server-key.pem > server-req.pem
[root@mysql newcerts]# openssl req -newkey rsa:2048 -days 1000 -nodes -keyout server-key.pem > server-req.pem
Generating a 2048 bit RSA private key

Generate the ssl file on the mysql db server client
4.1 openssl x509 -req -in server-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > server-cert.pem
[root@mysql newcerts]# openssl x509 -req -in server-req.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > server-cert.pem
Signature ok
