Configuration Parameters

To adjust the configuration, define any of the following applicable constants in your wp-config.php file.

• MYSQL_SSL_KEY [default: not set]

  The path name to the key file. (RSA Key)

• MYSQL_SSL_CERT [default: not set]

  The path name to the certificate file.

• MYSQL_SSL_CA [default: not set]

  The path name to the certificate authority file in PEM format.

• MYSQL_SSL_CA_PATH [default: not set]

  The pathname to a directory that contains trusted SSL CA certificates in PEM format.

• MYSQL_SSL_CIPHER [default: not set]

  A list of allowable ciphers to use for SSL encryption. You can leave this blank if you want to just use the strongest available.

Turning on SSL

First please note, only the mysqli (MySQL Improved) extension is supported this is the default extension used by WordPress however if you do not have the extension installed WordPress will fallback on the much older mysql extension which does not support secure connections.

Depending on your database configuration you may not need to set all the available options. For example when connecting to RDS Amazon helpfully provides a certificate bundle so once that’s downloaded to the server all that’s need is to set the CA option:

define( 'MYSQL_SSL_CA', '/path/to/rds-combined-ca-bundle.pem'
);

Once SSL keys / certs have been configured you via the defines above define an WP core constant to pass a use SSL flag to the mysqli client also in your wp-config.php file.

define( 'MYSQL_CLIENT_FLAGS', MYSQLI_CLIENT_SSL
);

If you are using the MySQL Native Driver and MySQL 5.6 or later mysqli_real_connect() will verify the server SSL certificate before connecting. If the SSL cert installed on the MySQL server your are connecting to is not valid PHP will refuse to connect. A flag was added to disable server certificate validation. If your server has an invalid certificate turn on SSL and turn off validation like so:

define( 'MYSQL_CLIENT_FLAGS', MYSQLI_CLIENT_SSL | MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT
);

Example Config

Aside from setting the normal MySQL connection parameters the minimum configs to get SSL connections to the database will look something like this in wp-config.php :

define( 'MYSQL_SSL_CA', '/path/to/ca-bundle.pem' );
define( 'MYSQL_CLIENT_FLAGS', MYSQLI_CLIENT_SSL );
