出现错误 Host 'localhost' is not allowed to connect to this MariaDB server" when trying to connect 的话可以用能连接上mysql的方法,先连接上,然后执行


#1.授权法
GRANT ALL PRIVILEGES ON *.* TO 'user'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION; // localhost:表示从localhost连接到mysql服务器,或者127.0.0.1 同理
#刷新权限
FLUSH   PRIVILEGES;

#或者
GRANT ALL PRIVILEGES ON *.* TO 'user'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;//%表示从任何IP连接到服务器
#刷新权限
FLUSH   PRIVILEGES;
