@Arthur Halma response: 只有当服务器能够提供远程(未过滤)神秘器连接,并配备与沥滤相同的服务器时,才有效。 如果没有外部连接或防火墙过滤连接,这可以退回“无人所知的MySQL服务器”。
Ultimately there is no sure way to check if a database is running unless you have permissions and the host information and ports. Even with a server that is under a Denial of Service (DoS) attack of MySQL, that will stop dynamic websites from loading, will not cause an unknown MySQL. Most companies filter their traffic by ip address to their MySQL server to stop potential DoS attacks.
