解决办法:
一、改表法(推荐使用)
可能是帐号不允许从远程登陆,只能在localhost。这个时候只要在localhost的那台电脑,登入mysql后,更改 mysql 数据库里的 user”表里的 host”项,把localhost改成%。
shell>mysql -u root -p
mysql>use mysql;
mysql>update user set host = '%' where user = 'root' and host='localhost';
mysql>select host, user from user;
mysql>flush privileges;
二、授权法
1、用户名为myuser使用密码mypassword从任何主机连接到mysql服务器:
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
2、用户名为myuser从ip为192.168.238.145的主机连接到mysql服务器,并使用mypassword作为密码连接:
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.238.145' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
3、用户名为myuser从ip为192.168.1.6的主机连接到mysql服务器的mydb数据库,并使用mypassword作为密码:
GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
