Host 'admin-PC' is not allowed to connect to this MySQL server

问题："Host 'admin-PC' is not allowed to connect to this MySQLserver"   （其中，admin-PC为我的机器名）

原因：安装MySQL时没有勾选“Enable root access from remote machines”

解决办法：执行命令

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypassword';

flush privileges;
