: null, message from server: "Host '14.16.**' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'"

这个问题表明你的 MySQL 服务器因为来自 IP 地址 14.16.** 的多次连接错误而阻止了该主机的连接请求。MySQL 有一个安全机制,当从某个 IP 发生过多失败的连接尝试时,它会自动封锁这个 IP,以防止潜在的恶意攻击或误操作导致的服务过载。
要解决这个问题,你可以按照错误提示中的建议,使用 mysqladmin 命令来清除被封锁的主机列表。以下是操作步骤:

登录到 MySQL 服务器: 首先,你需要在服务器上以具有足够权限的用户身份登录。这通常意味着你需要使用 root 用户或者具有 FLUSH_HOSTS 权限的其他用户。
  1. mysql -u root -p
复制代码


运行 mysqladmin 命令: 执行以下命令来清除被封锁的主机列表:

  1. flush-hosts
复制代码
