1、修改localhost
更改 "mysql"
數據庫里的 "user" 表里的 "host" 項，從"localhost"改成"%"
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
mysql>FLUSH PRIVILEGES;
2、指定授權
使用myuser/mypassword從任何主機連接到mysql服務器:
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
使用myuser/mypassword從ip為192.168.225.166的主機連接到mysql服務器:
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.225.166' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
3、泛授權
mysql -h localhost -u root
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION; //賦予任何主機上以root身份訪問數據的權限
mysql>FLUSH PRIVILEGES;
