mysql error number 2003

Can't connect to MySQL server xxx.xxx.xxx.xxx (10061)

在ubuntu 9.04中默认安装了mysql，默认只能本地访问，google了一下：

采用

登录到MySQL服务器端，在mysql库下执行

grant all on *.* to 'remote'@'172.16.21.39' identified by 'password';

即可

如果要设置为任何客户端都可以以root连接的话，可以这么写：

grant all on *.* to 'root'@'%' identifiied by 'root的密码'

格式：grant select on 数据库.* to 用户名@登录主机 identified by "密码"

类似这用方法的整理如下：

1。 改表法。可能是你的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，从"localhost"改称"%"

mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user;

2. 授权法。例如，你想myuser使用mypassword从任何主机连接到mysql服务器的话。

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

但问题仍没有解决：

找到 命令 mysql> flush privileges //使修改生效

显示影响了零行。

问题依然没有解决，重新启动mysql sudo /etc/init.d/mysql restart

还是不行。

从 http://www.blogjava.net/waterjava/archive/2008/04/27/196385.html
了解到mysql有本机绑定，找到问题所在。

编辑 /etc/mysql/my.cnf

# Instead of skip-networking the default is now to listen only on

# localhost which is more compatible and is not less secure.

bind-address = 127.0.0.1

将”bind-address = 127.0.0.1“注释

sudo /etc/init.d/mysql restart重启即可远程访问

问题解决

如果要设置为任何客户端都可以以root连接的话，可以这么写：

进入mysql,

grant all on *.* to 'root'@'%' identifiied by 'root的密码'
