1. 背景
* 在生产环境下，安全总是无法忽视的问题，数据库安全则是重中之重，因为所有的数据都存放在数据库中
* 当使用非加密方式连接MySQL数据库时，在网络中传输的所有信息都是明文的，可以被网络中所有人截取，敏感信息可能被泄露。在传送敏感信息（如密码）时，可以采用SSL连接的方式。
* 版本小于5.7.6时按照 MySQL 5.6 SSL配置的方式进行。
2. MySQL 连接方式
* socket连接
* TCP非SSL连接
* SSL安全连接
* SSL + 密码连接 [version > MySQL 5.7.5]
* SSL + 密码 + 密钥连接
3. SSL 简介
* SSL指的是SSL/TLS，其是一种为了在计算机网络进行安全通信的加密协议。假设用户的传输不是通过SSL的方式，那么其在网络中以明文的方式进行传输，而这给别有用心的人带来了可乘之机。所以，现在很多网站其实默认已经开启了SSL功能，比如Facebook、Twtter、YouTube、淘宝等。
4. 环境 [ 关闭SeLinux ]
* system 环境
ShopEx助理
一个类似淘宝助理、ebay助理的客户端程序，用来方便的在本地处理商店数据，并能够在本地商店、网上商店和第三方平台之间实现数据上传下载功能的工具。功能说明如下：1.连接本地商店：您可以使用ShopEx助理连接一个本地安装的商店系统，这样就可以使用助理对本地商店的商品数据进行编辑等操作，并且数据也将存放在本地商店数据库中。默认是选择“本地未安装商店”，本地还未安

5. SSL配置
* 利用自带工具生成SSL相关文件
[root@MySQL ~]# /usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/data/mysql_dataGenerating a 2048 bit RSA private key..........................................................................+++.....+++writing new private key to 'ca-key.pem'-----Generating a 2048 bit RSA private key.......................................................................................................................................................................+++...+++writing new private key to 'server-key.pem'-----Generating a 2048 bit RSA private key.....................+++...........................................+++writing new private key to 'client-key.pem'----- * 查看生成的SSL文件[root@MySQL ~]# ls -l /data/mysql_data/*.pem-rw------- 1 root root 1679 Jun 24 20:54 /data/mysql_data/ca-key.pem-rw-r--r-- 1 root root 1074 Jun 24 20:54 /data/mysql_data/ca.pem-rw-r--r-- 1 root root 1078 Jun 24 20:54 /data/mysql_data/client-cert.pem-rw------- 1 root root 1675 Jun 24 20:54 /data/mysql_data/client-key.pem-rw------- 1 root root 1675 Jun 24 20:54 /data/mysql_data/private_key.pem-rw-r--r-- 1 root root 451 Jun 24 20:54 /data/mysql_data/public_key.pem-rw-r--r-- 1 root root 1078 Jun 24 20:54 /data/mysql_data/server-cert.pem-rw------- 1 root root 1675 Jun 24 20:54 /data/mysql_data/server-key.pem* 重启 MySQL 服务[root@MySQL ~]# /etc/init.d/mysqld restartShutting 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=0mysql: [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

7. SSL + 密码 + 密钥连接
* 创建用户并指定 X509 [ SSL+密钥 ] 连接 [ MySQL 5.7后推荐使用create user 方式创建用户 ]
mysql> create user 'X509_test'@'%' identified by '123' require X509;Query OK, 0 rows affected (0.00 sec)* 通过密码连接测试[root@MySQL ~]# mysql -h 192.168.60.129 -uX509_test -p'123' --ssl=0mysql: [Warning] Using a password on the command line interface can be insecure.ERROR 1045 (28000): Access denied for user 'X509_test'@'192.168.60.129' (using password: YES)* 通过 SSL +密码 连接测试[root@MySQL ~]# mysql -h 192.168.60.129 -uX509_test -p'123' --sslmysql: [Warning] Using a password on the command line interface can be insecure.ERROR 1045 (28000): Access denied for user 'X509_test'@'192.168.60.129' (using password: YES) * 通过 SSL + 密码＋密钥连接测试
