mysql5.7 ssl_MySQL5.7 开启SSL
MySQL5.7配置SSL加密的方式比较简单。
生成证书文件
[root@ ~]# bin/mysql_ssl_rsa_setup --datadir=/data/database/mysql
[root@ ~]# chown mysql:mysql /data/database/mysql -R
[root@ ~]# ll /data/database/mysql -rt
.....
-rw------- 1 mysql mysql 1675 Mar 28 16:35 ca-key.pem # CA 私钥
-rw-r--r-- 1 mysql mysql 1082 Mar 28 16:35 ca.pem # 自签的CA证书，客户端连接也需要提供
-rw-r--r-- 1 mysql mysql 1086 Mar 28 16:35 client-cert.pem # 客户端连接服务端需要提供的证书文件
-rw------- 1 mysql mysql 1675 Mar 28 16:35 client-key.pem #客户端连接服务端需要提供的私钥文件
-rw------- 1 mysql mysql 1679 Mar 28 16:35 private_key.pem #私钥公钥的私有成员
-rw-r--r-- 1 mysql mysql 451 Mar 28 16:35 public_key.pem #私钥公钥的共有成员
-rw-r--r-- 1 mysql mysql 1086 Mar 28 16:35 server-cert.pem #服务端证书文件
-rw------- 1 mysql mysql 1679 Mar 28 16:35 server-key.pem #服务端私钥文件
配置：
[root@ ~]# vim /etc/my.cnf
#ssl
ssl-ca=/data/database/mysql/ca.pem
ssl-cert=/data/database/mysql/server-cert.pem
ssl-key=/data/database/mysql/server-key.pem
然后重启一下
查看一下：
(root@localhost) [(none)]> show global variables like '%ssl%';

创建一个SSL登陆的账号
(root@localhost) [(none)]> create user [email protected] identified by '123456' require ssl ; #require ssl表示强制使用SSL
(root@localhost) [(none)]> grant all on *.* to [email protected] ;
(root@localhost) [(none)]> flush privileges;
登录
使用unix socket无法加密呀
通过--ssl-cert=/xxx/client-cert.pem --ssl-key=/xxx/client-key.pem 指定客户端证书和key
mysql -uadmin -p123456 -P3306 -h 127.0.0.1 --ssl-cert=/data/database/mysql/client-cert.pem --ssl-key=/data/database/mysql/client-key.pem
