MySQL uses SSL to generate a key

-- Does mysqlssl generate the key 1checkssl enable mysqlgt; showvariableslike

-- Mysql ssl generation key 1 check if ssl has enabled mysqlgt; show variables like

-- Mysql ssl generates a key

1 check whether ssl is enabled
Mysql> show variables like '% ssl % ';
+ --------------- + ---------- +
| Variable_name | Value |
+ --------------- + ---------- +
| Have_openssl | DISABLED |
| Have_ssl | DISABLED |
| Ssl_ca |
| Ssl_capath |
| Ssl_cert |
| Ssl_cipher |
| Ssl_crl |
| Ssl_crlpath |
| Ssl_key |
+ --------------- + ---------- +
9 rows in set (0.00 sec)

2 is not enabled, so open
Set the ssl parameter at the end of my. cnf and restart the mysql service.

3. Use openssl to generate the certificate configuration and generate the key on the 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 ininitialized
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

4. generate an 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
Subject =/C = ch/ST = shh/L = ssh/O = ea/OU = db/CN = mysql. yest. nos/emailAddress = cm@xx.com
Getting CA Private Key

4.2 openssl req-newkey rsa: 2048-days 1000-nodes-keyout client-key.pem> client-req.pem

[Root @ mysql newcerts] # openssl req-newkey rsa: 2048-days 1000-nodes-keyout client-key.pem> client-req.pem
Generating a 2048 bit RSA private key
