MySQL 开启 SSL 连接的技术教程

mysql打开ssl

在本文中,我们将学习如何在 MySQL 中开启 SSL 连接,SSL(Secure Sockets Layer)是一种安全协议,用于在不安全的网络环境中保护数据传输的安全,通过使用 SSL,我们可以确保在客户端和服务器之间的通信是加密的,从而防止数据被窃取或篡改。

1. 安装 SSL 证书

要启用 SSL 连接,首先需要为 MySQL 服务器安装 SSL 证书,证书通常由权威机构颁发,例如 Let’s Encrypt、DigiCert 等,购买证书后,将其安装到服务器上,具体安装步骤因服务器操作系统而异,以下是在 Ubuntu 系统上安装证书的示例:

sudo apt-get update
sudo apt-get install certbot python3-certbot-nginx
sudo certbot --nginx -d example.com -d www.example.com

2. 配置 MySQL 服务器

安装证书后,需要配置 MySQL 服务器以使用 SSL,编辑 MySQL 配置文件 `/etc/mysql/mysql.conf.d/mysqld.cnf`,在 `[mysqld]` 部分添加以下内容:

[mysqld]
ssl_ca = /etc/mysql/ca-cert.pem
ssl_cert = /etc/mysql/server-cert.pem
ssl_key = /etc/mysql/server-key.pem

`ssl_ca` 指定了 CA 证书的路径,`ssl_cert` 和 `ssl_key` 分别指定了服务器证书和私钥的路径,请根据实际情况修改这些路径。

3. 重启 MySQL 服务

保存配置文件后,重启 MySQL 服务以使更改生效:

sudo systemctl restart mysql

4. 创建信任证书存储区

为了让客户端能够验证服务器的证书,我们需要创建一个信任证书存储区,生成一个新的受信任的根证书:

openssl req -x509 -newkey rsa:4096 -nodes -sha256 -days 3650 
    -keyout ca-key.pem -out ca-cert.pem 
    -subj "/CN=localhost"

接下来,创建一个新的用户并授予其访问数据库的权限:

mysql打开ssl

CREATE USER 'mysql'@'%' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON *.* TO 'mysql'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;

创建一个新的受信任的证书存储区:

mkdir -p ~/trusted
openssl x509 -in ca-cert.pem -outform der 
    -out ~/trusted/ca-cert.der 
    -noout 
    -signkey ca-key.pem 
    -passin pass:your_password

5. 在客户端上启用 SSL 连接

你可以在客户端上启用 SSL 连接了,以下是一个使用 Python `pymysql` 库连接到 MySQL 服务器的示例:

“`python

import pymysql

import socket

from cryptography import x509

from cryptography.hazmat.backends import default_backend

from cryptography.hazmat.primitives import hashes, hmac, padding, serialization, selectors

from cryptography.hazmat.primitives.asymmetric import padding as asym_padding

from cryptography.x509 import CertificateBuilder, NameOID, load_pem_x509_certificate
