很多情形需要遇到mysql的远程访问连接,但root用户只能本地连接。要实现你的的pc上的mysql数据库远程连接访问,必须另开账户。 首先, 在MySQL Server端: 执行mysql 命令进入mysql 命令模式, Sql代码 mysqlusemysql; mysql GRANT ALL ON *.* TO admin@ '%'

            很多情形需要遇到mysql的远程访问连接,但root用户只能本地连接。要实现你的的pc上的mysql数据库远程连接访问,必须另开账户。

         首先,在MySQL Server端: 
       执行mysql 命令进入mysql 命令模式, 
       Sql代码 mysql的远程访问连接eoe mysql的远程访问连接eoe

  1.  mysql> use mysql;   
  2. mysql> GRANT ALL ON *.* TO admin@'%' IDENTIFIED BY 'admin' WITH GRANT OPTION;   
  3. #这句话的意思 ,允许任何IP地址(上面的 % 就是这个意思)的电脑 用admin帐户  和密码(admin)来访问这个MySQL Server。                                                                                              

        实现远程登录的方式:

  1. 在另一台MySQL 客户端(装有mysql程序包的pc ,windows或者是linux均可) 
    执行命令: 

    Sql代码 mysql的远程访问连接eoe mysql的远程访问连接eoe

    1. mysql -h172.21.5.29 -uadmin -padmin   即可了   
    2. //172.21.5.29就是MySQL Server的IP地址,admin admin就是刚才在 172.21.5.29上设置的远程访问帐户

     注意:

     如果上面的命令你执行完毕, 你在 本地就是localhost , 执行 : 

      Sql代码 mysql的远程访问连接eoe mysql的远程访问连接eoe

  1.  mysql -hlocalhost -uadmin -padmin   
     结果是失败的。原来 上面的 % 竟然不包括localhost 所以你还必须加上这样的 命令:  
     mysql>GRANT ALL ON *.* TO admin@'localhost'  IDENTIFIED BY 'admin' WITH GRANT OPTION;

     此命令才能保证在本地能够以admin账户登录。

      如果上面的信息还不够清晰,可以参考如下的内容:

     

   MySQL远程访问权限,允许远程连接的开启

 

   1、登陆mysql数据库    

   mysql -u root -p

   查看user表  www.2cto.com  

   mysql> use mysql;

   Database changed

   mysql> select 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

   mysql> use mysql;

   Database changed

   mysql> grant all privileges  on *.* to root@'%' identified by "root";

   Query OK, 0 rows affected (0.00 sec)  www.2cto.com  

   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密码root远程访问该机器上的MySql.

   3、实现远程连接(改表法)

   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.

What are some common security vulnerabilities in MySQL?What are some common security vulnerabilities in MySQL?Apr 26, 2025 am 12:27 AM

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

How can you identify slow queries in MySQL?How can you identify slow queries in MySQL?Apr 26, 2025 am 12:15 AM

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

How can you monitor MySQL server health and performance?How can you monitor MySQL server health and performance?Apr 26, 2025 am 12:15 AM

To monitor the health and performance of MySQL servers, you should pay attention to system health, performance metrics and query execution. 1) Monitor system health: Use top, htop or SHOWGLOBALSTATUS commands to view CPU, memory, disk I/O and network activities. 2) Track performance indicators: monitor key indicators such as query number per second, average query time and cache hit rate. 3) Ensure query execution optimization: Enable slow query logs, record and optimize queries whose execution time exceeds the set threshold.

Compare and contrast MySQL and MariaDB.Compare and contrast MySQL and MariaDB.Apr 26, 2025 am 12:08 AM

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.

How does MySQL's licensing compare to other database systems?How does MySQL's licensing compare to other database systems?Apr 25, 2025 am 12:26 AM

MySQL uses a GPL license. 1) The GPL license allows the free use, modification and distribution of MySQL, but the modified distribution must comply with GPL. 2) Commercial licenses can avoid public modifications and are suitable for commercial applications that require confidentiality.

When would you choose InnoDB over MyISAM, and vice versa?When would you choose InnoDB over MyISAM, and vice versa?Apr 25, 2025 am 12:22 AM

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

Explain the purpose of foreign keys in MySQL.Explain the purpose of foreign keys in MySQL.Apr 25, 2025 am 12:17 AM

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.
