MySQL 5.7 的SSL加密方法

标签：dir   connect   https   port   man   指定   版本   star   SSL加密   

MySQL 5.7.6或以上版本

（1）创建证书开启SSL验证
--安装openssl
yum install -y openssl
openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013

--安装证书
/usr/local/mysql/bin/mysql_ssl_rsa_setup   --datadir=/data/mysql/mysql3306/data


--修改权限
chown -R mysql:mysql /data/mysql/mysql3306/data


pwd
/data/mysql/mysql3306/data
[root@VM_45_133_centos Wed Jun 28 10:51:22 data]# ll
total 1024072

-rw-r--r-- 1 root  root        1078 Jun 28 10:48 client-cert.pem

-rw------- 1 root  root        1679 Jun 28 10:48 private_key.pem
-rw-r--r-- 1 root  root         451 Jun 28 10:48 public_key.pem
drwxr-x--- 2 mysql mysql       4096 Jun 23 10:48 school

客户端连接需要的证书，当然不用证书也是可以的
-rw-r--r-- 1 root  root        1074 Jun 28 10:48 ca.pem
-rw-r--r-- 1 root  root        1078 Jun 28 10:48 client-cert.pem
-rw------- 1 root  root        1679 Jun 28 10:48 client-key.pem
-rw------- 1 root  root        1679 Jun 28 10:48 private_key.pem

服务器上的证书
-rw-r--r-- 1 root  root        1074 Jun 28 10:48 ca.pem
-rw------- 1 root  root        1679 Jun 28 10:48 ca-key.pem
-rw-r--r-- 1 root  root         451 Jun 28 10:48 public_key.pem
-rw-r--r-- 1 root  root        1078 Jun 28 10:48 server-cert.pem
-rw------- 1 root  root        1675 Jun 28 10:48 server-key.pem

--修改my.cnf
#########SSL#############
ssl-ca = /data/mysql/mysql3306/data/ca.pem
ssl-cert = /data/mysql/mysql3306/data/server-cert.pem
ssl-key = /data/mysql/mysql3306/data/server-key.pem



（2）重启mysql
/etc/init.d/mysql stop
/etc/init.d/mysql start



--查看ssl参数状态，查看have_ssl，为YES，这表示已经开始支持SSL了
show global variables like ‘%ssl%‘;
+---------------+--------------------------------------------+
| Variable_name | Value                                      |
+---------------+--------------------------------------------+
| have_openssl  | YES                                        |
| have_ssl      | YES                                        |
| ssl_ca        | /data/mysql/mysql3306/data/ca.pem          |
| ssl_capath    |                                            |
| ssl_cert      | /data/mysql/mysql3306/data/server-cert.pem |
| ssl_cipher    |                                            |
| ssl_crl       |                                            |
| ssl_crlpath   |                                            |
| ssl_key       | /data/mysql/mysql3306/data/server-key.pem  |
+---------------+--------------------------------------------+



show global status like ‘%ssl%‘;
+--------------------------------+--------------------------+
| Variable_name                  | Value                    |
+--------------------------------+--------------------------+
| Com_show_processlist           | 0                        |
| Ssl_accept_renegotiates        | 0                        |

+--------------------------------+--------------------------+



查看SSL的加密方式
show global variables like ‘tls_version‘;
+---------------+---------------+
| Variable_name | Value         |
+---------------+---------------+
| tls_version   | TLSv1,TLSv1.1 |
+---------------+---------------+




（3）配置SSL用户
取消ssl验证
grant all privileges on *.* to abcssl@‘%‘ identified by ‘123456‘ require none;
alter user abcssl@‘%‘ require none;
--强制ssl验证，即使设置了强制ssl，在登录时候使用--ssl-mode=disable依然可以避开ssl验证
grant all privileges on *.* to abcssl@‘%‘ identified by ‘123465‘ require ssl;
alter user abcssl@‘%‘ require ssl;



查看是否开启强制用户使用SSL
select user,host,ssl_type,ssl_cipher  from mysql.user;
+-----------+-----------+----------+------------+
| user      | host      | ssl_type | ssl_cipher |
+-----------+-----------+----------+------------+
| root      | %         |          |            |
| mysql.sys | localhost |          |            |
| abcssl    | %         | ANY      |            |
+-----------+-----------+----------+------------+


（4）连接数据库的时候，带上SSL
不指定客户端证书方式
5.6
--ssl、--disable-ssl、--skip-ssl：在mysql5.7是将被废弃的选项，将来版本不再支持，建议使用--ssl-mode选项，
/usr/local/mysql/bin/mysql -uroot -p -h127.0.0.1 --ssl  默认为1
/usr/local/mysql/bin/mysql -uroot -p -h127.0.0.1 --ssl=0
/usr/local/mysql/bin/mysql -uroot -p -h127.0.0.1 --ssl=1  默认为1
/usr/local/mysql/bin/mysql -uroot -p -h127.0.0.1 --disable-ssl
/usr/local/mysql/bin/mysql -uroot -p -h127.0.0.1 --skip-ssl

5.7
/usr/local/mysql/bin/mysql -uroot -p -h127.0.0.1 --ssl-mode=disable
/usr/local/mysql/bin/mysql -uroot -p -h127.0.0.1 --ssl-mode=required  默认required

从另一台机器连接过去也可以ssl加密，表明不需要安装客户端证书的
/usr/local/mysql/bin/mysql -uroot -p -h10.105.45.133 --ssl-mode=required



指定客户端证书方式，5.6的方式，5.7也可以用
/usr/local/mysql/bin/mysql --ssl-ca=/data/mysql/mysql3306/data/ca.pem \
--ssl-cert=/data/mysql/mysql3306/data/client-cert.pem \
--ssl-key=/data/mysql/mysql3306/data/client-key.pem \
-uroot -p -h127.0.0.1



（5）连接验证连接是否用了ssl

JDBC客户端的解决方法
连接字符串url中加入ssl=true或false：
url=jdbc:mysql://127.0.0.1:3306/framework?characterEncoding=utf8&useSSL=true
