Navicat for mysql 远程连接 mySql数据库10061、1045错误

navicat remote connection

有朋友可能会碰到使用Navicat for mysql 远程连接 mySql数据库会提示10061、1045错误或 2003-Can’t connect to MySQL on ’192.168.1.2’(10061),这个原因是因为MySQL不准许远程连接。

最简单的办法是

MySQL远程配置

 代码如下 复制代码


GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'your paaa'; %表示多有机器。

打开3306端口,为防火墙设置例外,放行3306.

但你必须有root权限了,

还可以如下方法修改:

1:在服务端MySQL文件夹下找到my.ini文件。修改bind-address=127.0.0.1 为 bind-address=0.0.0.0 (在MySQL 5的my.ini中未发现此项)

2:重新启动MySQL服务。

测试连接情况:

如果没有给远程登录用户添加所有机器都能访问的权限,将会出现“1045- denied for user root@IT(using password:NO)”,这表明需要添加权限;

添加命令如下:

 代码如下 复制代码

1)grant all on *.* to 用户名@"%" identified by "密码";

2)flush privileges;

完成以上步骤,就可以远程访问MySQL了。


如果上面办法不能解决我们可以开启MySQL远程访问权限 允许远程连接

1、登陆mysql   

 代码如下 复制代码

mysql -u root -p

查看user表

 代码如下 复制代码
mysql> use mysql;
Database changed
mysql> host,user,password from user;
+--------------+------+-------------------------------------------+
| host         | user | password                                  |
+--------------+------+-------------------------------------------+
| localhost    | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| 192.168.1.1 | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
2 rows in set (0.00 sec)

 

   可以看到在user表中已创建的root用户。host字段表示登录的主机,其值可以用IP,也可用主机名,

   (1)有时想用本地IP登录,那么可以将以上的Host值改为自己的Ip即可。

2、实现远程连接(授权法)

   将host字段的值改为%就表示在任何客户端机器上能以root用户登录到mysql服务器,建议在开发时设为%。  
   update user set host = ’%’ where user = ’root’;

   将权限改为ALL PRIVILEGES

 代码如下 复制代码

mysql> use mysql;
Database changed
mysql> grant all privileges  on *.* to root@'%' identified by "root";
Query OK, 0 rows affected (0.00 sec)

mysql> select host,user,password from user;
+--------------+------+-------------------------------------------+
| host         | user | password                                  |
+--------------+------+-------------------------------------------+
| localhost    | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| 192.168.1.1 | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
| %            | root | *A731AEBFB621E354CD41BAF207D884A609E81F5E |
+--------------+------+-------------------------------------------+
3 rows in set (0.00 sec)

这样机器就可以以用户名root远程访问该机器上的MySql.

3、实现远程连接(改表法)

 代码如下 复制代码

use mysql;

update user set host = '%' where user = 'root';

这样在远端就可以通过root用户访问Mysql
