将您的应用程序配置为在连接到数据库时使用 SSL。在 CodeIgniter 中，它是database.php文件输入/application/config/。确保您使用的所有 MySQL 驱动程序都启用了 SSL。从以下位置下载 SSL 证书https://www.digicert.com/CACerts/BaltimoreCyberTrustRoot.crt.pem https://www.digicert.com/CACerts/BaltimoreCyberTrustRoot.crt.pem并将其存储在您的应用程序的目录中，例如/cert/BaltimoreCyberTrustRoot.crt.pem
