* 修改数据目录下生成的SSL文件所属用户与权限
[root@MySQL ~]# chown -v mysql.mysql /data/mysql_data/*.pem
changed ownership of `/data/mysql_data/ca-key.pem' to mysql:mysql
changed ownership of `/data/mysql_data/ca.pem' to mysql:mysql
changed ownership of `/data/mysql_data/client-cert.pem' to mysql:mysql
changed ownership of `/data/mysql_data/client-key.pem' to mysql:mysql

changed ownership of `/data/mysql_data/server-cert.pem' to mysql:mysql
changed ownership of `/data/mysql_data/server-key.pem' to mysql:mysql
* 查看生成的SSL文件
[root@MySQL ~]# ls -l /data/mysql_data/*.pem

* 重启 MySQL 服务
[root@MySQL ~]# /etc/init.d/mysqld restart
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS!
* 连接MySQL 查看SSL开启状态
have_openssl 与 have_ssl 值都为YES表示ssl开启成功
mysql> show variables like 'have%ssl%';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| have_openssl | YES |
| have_ssl | YES |
+---------------+-------+
2 rows in set (0.03 sec)
6. SSL + 密码连接测试
* 创建用户并指定 SSL 连接 [ MySQL 5.7后推荐使用create user 方式创建用户 ]
mysql> create user 'ssl_test'@'%' identified by '123' require SSL;
Query OK, 0 rows affected (0.00 sec)
* 通过密码连接测试 [ 默认采用SSL连接，需要指定不使用SSL连接 ]
[root@MySQL ~]# mysql -h 192.168.60.129 -ussl_test -p'123' --ssl=0
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'ssl_test'@'192.168.60.129' (using password: YES)
* 通过 SSL + 密码 连接测试
SSL: Cipher in use is DHE-RSA-AES256-SHA 表示通过SSL连接
[root@MySQL ~]# mysql -h 192.168.60.129 -ussl_test -p'123' --ssl
mysql: [Warning] Using a password on the command line interface can be insecure.
WARNING: --ssl is deprecated and will be removed in a future version. Use --ssl-mode instead.
