当远程连接MySQL数据库的时候显示Can't connect to MySQL server (10060),我们从以下几个方面入手,找出错误的原因:

1.网络不通。

检查能不能ping通。

2.防火墙设置。

防火墙是否放过mysql的进程,是否屏蔽了mysql的3306端口。

3.mysql的账户设置。

mysql账户是否不允许远程连接。如果无法连接可以尝试以下方法:

<ol>
<li><span>mysql -u root -p    //登录MySQL  </span></li>
<li><span> </span></li>
<li>
<span>mysql</span><span>></span><span> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION;     //任何远程主机都可以访问数据库  </span>
</li>
<li><span> </span></li>
<li>
<span>mysql</span><span>></span><span> FLUSH PRIVILEGES;    //需要输入次命令使修改生效  </span>
</li>
<li><span> </span></li>
<li>
<span>mysql</span><span>></span><span> EXIT    //退出 </span>
</li>
</ol>
Copy after login

也可以通过修改表来实现远程:

<ol>
<li><span>mysql -u root -p  </span></li>
<li><span> </span></li>
<li>
<span>mysql</span><span>></span><span> use mysql;  </span>
</li>
<li><span> </span></li>
<li>
<span>mysql</span><span>></span><span> update user set </span><span>host</span><span> = </span><span>'%'</span><span> where </span><span>user</span><span> = </span><span>'root'</span><span>;  </span>
</li>
<li><span> </span></li>
<li>
<span>mysql</span><span>></span><span> select host, user from user; </span>
</li>
</ol>
Copy after login

GRANT ALL PRIVILEGES

一。 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"%"

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


二. 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。
1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

2.FLUSH PRIVILEGES;


如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器,并使用mypassword作为密码
1. GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
2. FLUSH PRIVILEGES;

另外一种方法.
在安装mysql的机器上运行:
1、d:\mysql\bin\>mysql -h localhost -u root
//这样应该可以进入MySQL服务器
2、mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION
//赋予任何主机访问数据的权限

3、mysql>FLUSH PRIVILEGES
//修改生效
4、mysql>EXIT
//退出MySQL服务器
这样就可以在其它任何的主机上以root身份登录啦!


ps:安装mysql后,增加mysql的root用户的密码:  mysql -u root password  'your_password‘
