我无法通过虚拟 IP 连接到数据库服务器
我按照本指南操作，但当我的网络服务器尝试连接它时，它失败了
sudo mysql -u wordpress -h 192.168.122.98 -p
Enter password:
ERROR 1045 (28000): Access denied for user 'wordpress'@'db1' (using password: YES)
该接口的虚拟 IP 是：192.168.122.98
我的数据库 IP 是：192.168.122.187
我可以直接连接到数据库：
sudo mysql -u wordpress -h 192.168.122.187 -p
Enter password:

将您的 Web 服务器 IP 添加到数据库：
