1. 查看数据库是否开启SSL加密连接功能
mysql> show variables like "%ssl%";
+--------------------+-----------------+
| Variable_name | Value |
+--------------------+-----------------+
| have_openssl | YES |
| have_ssl | YES |
| mysqlx_ssl_ca | |
| mysqlx_ssl_capath | |
| mysqlx_ssl_cert | |
| mysqlx_ssl_cipher | |
| mysqlx_ssl_crl | |
| mysqlx_ssl_crlpath | |
| mysqlx_ssl_key | |
| ssl_ca | ca.pem |
| ssl_capath | |
| ssl_cert | server-cert.pem |
| ssl_cipher | |

2. Linux命令连接MySQL数据库（SSL方式）
（条件：下载ca.pem,client-cert.pem,client-key.pem至Linux环境）
#mysql -h[IP] -P[port] -u[username] --ssl-ca=/root/pem/ca.pem --ssl-cert=/root/pem/client-cert.pem --ssl-key=/root/pem/client-key.pem -p[password]
