Yes, you can configure your MySQL server to use SSL/TLS encryption with an SSL certificate signed by a Certificate Authority (CA). This will secure the connections between your MySQL server and clients, ensuring data privacy and protection against eavesdropping.
Here’s a general guide on how to set up SSL for MySQL:
1. Generate or Obtain an SSL Certificate
You can either:
Use a self-signed certificate (for internal purposes)
Obtain a certificate from a trusted CA (for production)
If you're obtaining a signed certificate from a CA, you need to generate a Certificate Signing Request (CSR) and get it signed by the CA.
2. Enable SSL in MySQL Configuration
Modify the MySQL server configuration file (my.cnf or my.ini).
Locate the configuration file:
sudo nano /etc/mysql/my.cnf # Ubuntu
Add the SSL configuration under the [mysqld] section. You will need the paths to the server certificate, CA certificate, and the server private key:
[mysqld]
ssl-ca=/path/to/ca-cert.pem
ssl-cert=/path/to/server-cert.pem
ssl-key=/path/to/server-key.pem
3. Restart MySQL Server
After editing the configuration file, restart the MySQL server to apply the changes:
sudo systemctl restart mysql
4. Verify SSL is Enabled
You can check if SSL is enabled by running the following query in the MySQL shell:
SHOW VARIABLES LIKE '%ssl%';
You should see have_ssl set to YES.
5. Enforce SSL for Specific Users (Optional)
If you want to enforce SSL for specific MySQL users, you can run:
ALTER USER 'username'@'hostname' REQUIRE SSL;
6. Client-Side Configuration
On the client side, you'll need to specify the CA certificate to verify the server's certificate. When connecting using mysql command-line client:
mysql --ssl-ca=/path/to/ca-cert.pem --host=your-server-hostname --user=username --password
By using a signed SSL certificate, the communication between your MySQL server and clients will be encrypted, and the identity of the server will be verified by the CA.
