    • set global max_allowed_packet=64*1024*1024; to set (with privileged account such as root)
    • ~/.my.cnf나 /etc/my.cnf등 여러 개의 cnf file이 있을 수 있으니 적절한 file에서 수정 후 mysql을 재시작(e.g. service mysql restart)하는 방식으로 해야 할 수도 있음
    • python code with MySQLdb or mysqlclient; cursor.execute('SET GLOBAL max_allowed_packet=67108864', ())root 권한이 필요해서 안될 듯
