这篇文章主要讲解了"mysql5.7怎么对ssl加密连接"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"mysql5.7怎么对ssl加密连接"吧！

该操作在mysql5.7及以后版本,5.6及以前版本不适用该操作

确认数据库版本号和端口号

mysql> select version();+-----------+| version() |+-----------+| 5.7.19    |+-----------+1 row in set (0.00 sec)

mysql> show variables like 'have%ssl%';+---------------+----------+| Variable_name | Value    |+---------------+----------+| have_openssl  | DISABLED || have_ssl      | DISABLED |+---------------+----------+2 rows in set (0.02 sec)

mysql> show variables like 'port';+---------------+-------+| Variable_name | Value |+---------------+-------+| port          | 3306  |+---------------+-------+1 row in set (0.01 sec)

mysql> show variables like 'datadir';+---------------+-------------------+| Variable_name | Value             |+---------------+-------------------+| datadir       | /data|+---------------+-------------------+1 row in set (0.01 sec)

1. 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=/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/ca-key.pem-rw-r--r-- 1 root root 1074 Jun 24 20:54 /data/ca.pem-rw-r--r-- 1 root root 1078 Jun 24 20:54 /data/client-cert.pem-rw------- 1 root root 1675 Jun 24 20:54 /data/client-key.pem-rw------- 1 root root 1675 Jun 24 20:54 /data/private_key.pem-rw-r--r-- 1 root root  451 Jun 24 20:54 /data/public_key.pem-rw-r--r-- 1 root root 1078 Jun 24 20:54 /data/server-cert.pem-rw------- 1 root root 1675 Jun 24 20:54 /data/server-key.pem

注意:将上述文件权限改为mysql所属

* 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)

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

[root@MySQL ~]# mysql -h 192.168.60.129 -ussl_test -p'123'  --sslmysql: [Warning] Using a password on the command line interface can be insecure.WARNING: --ssl is deprecated and will be removed in a future version.

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 'wang'@'%' identified by '123' require wang;Query OK, 0 rows affected (0.00 sec)

通过密码连接测试

[root@MySQL ~]# mysql -h 192.168.60.129 -uwang -p'123' --ssl=0mysql: [Warning] Using a password on the command line interface can be insecure.ERROR 1045 (28000): Access denied for user 'wang'@'192.168.60.129' (using password: YES)
