This is what we do when connecting to MySQL server as a client: ```python # https://github.com/PyMySQL/PyMySQL/issues/430#issuecomment-464837266 conn = pymysql.connect( host='127.0.0.1', port=3306, user='repl', password='123456', ssl={ 'ca': 'ssl/ca-cert.pem', 'cert': 'ssl/client-cert.pem', 'key': 'ssl/client-key.pem', # Effectively equals to --ssl-mode=VERIFY_CA 'check_hostname': False, } ) ``` Just wonder how to set SSL/TLS certificates when connecting to MySQL server as a replica?
