In this tutorial, we will walk you through the process of implementing SSL encryption for MySQL. Ensuring secure connections is crucial for data integrity and privacy. Let's dive in!

Prerequisites

Before you begin, make sure you have the following:

  • A MySQL server running
  • Access to the MySQL server configuration files
  • The necessary SSL certificate files (e.g., server-cert.pem, server-key.pem, ca-cert.pem)

Step 1: Generate SSL Certificate

First, you need to generate SSL certificate files. You can use OpenSSL for this purpose. Follow these steps:

  1. Generate a private key for the MySQL server:
openssl genpkey -algorithm RSA -out server-key.pem
  1. Generate a CSR (Certificate Signing Request):
openssl req -new -key server-key.pem -out server-csr.pem
  1. Submit the CSR to a Certificate Authority (CA) to obtain a certificate:
openssl x509 -req -in server-csr.pem -signkey server-key.pem -out server-cert.pem
  1. Generate a CA certificate to validate the server's certificate:
openssl req -x509 -newkey rsa:4096 -keyout ca-key.pem -out ca-cert.pem -days 365

Step 2: Configure MySQL Server

Next, you need to configure the MySQL server to use SSL. Open the MySQL configuration file (my.cnf or my.ini, depending on your system) and add the following lines:

[mysqld]
ssl-ca = /path/to/ca-cert.pem
ssl-cert = /path/to/server-cert.pem
ssl-key = /path/to/server-key.pem

Make sure to replace /path/to/ with the actual paths to your certificate files.

Step 3: Restart MySQL Server

After making changes to the MySQL configuration file, restart the MySQL server for the changes to take effect.

sudo systemctl restart mysql

Step 4: Connect to MySQL Using SSL

To connect to the MySQL server using SSL, use the following command:

mysql --ssl-ca=/path/to/ca-cert.pem --ssl-cert=/path/to/client-cert.pem --ssl-key=/path/to/client-key.pem -h <MySQL_host> -u <username> -p

Replace <MySQL_host>, <username>, and <path/to/...> with the appropriate values for your setup.
