安装完MySQL后,远程连接数据库的时候,出现ERROR 1130 (HY000): Host '192.168.0.1' is not allowed to connect tothis MySQLserver提示信息,不能远程连接数据库。考虑可能是因为系统数据库mysql中user表中的host是localhost的原因,于是,我尝试把这个改
安装完MySQL后,远程连接数据库的时候,出现ERROR 1130 (HY000): Host '192.168.0.1' is not allowed to connect tothis MySQLserver提示信息,不能远程连接数据库。考虑可能是因为系统数据库mysql中user表中的host是localhost的原因,于是,我尝试把这个值改为自己服务器的ip,果然就好用了,不过用mysql -u root -p命令就连不上数据库了,需要用mysql -h 服务器ip -uroot-p因为默认的连接mysql数据库user表中host的值,而这个命令的默认host是localhost,就连不上了。
具体操作方法:
用localhost连接上mysql后,
use mysql;
update user sethost='123.456.789.254';(IP为你想要远程连接数据库的本地机器的IP)
\q;
退出mysql,然后重新启动mysql就可以了。
其他解决方案
2.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 -pvmware
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>flush privileges;
mysql>select host, user from user;
3.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'@'192.168.0.1' IDENTIFIED BY'mypassword' WITH GRANT OPTION;
***********************************************************************
phpMyAdmin说是用户名密码的问题,这就奇怪了,root用户名密码肯定没有问题,而且通过命令行连接没有问题。又仔细查看配置文件,还是没有问题。于是去搜了一下,找到这个解决方法.
先用root登录MYSQL服务器,执行
mysql>set
原因是因为你使用的mysql服务器版本中使用了新的密码验证机制,这需要客户端的版本要在4.0以上,原来的密码函数被改为old_password();,这样使用password()生成的密码在旧的版本上就可以解决这个问题了.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

InnoDB effectively prevents phantom reading through Next-KeyLocking mechanism. 1) Next-KeyLocking combines row lock and gap lock to lock records and their gaps to prevent new records from being inserted. 2) In practical applications, by optimizing query and adjusting isolation levels, lock competition can be reduced and concurrency performance can be improved.

MySQL is not a programming language, but its query language SQL has the characteristics of a programming language: 1. SQL supports conditional judgment, loops and variable operations; 2. Through stored procedures, triggers and functions, users can perform complex logical operations in the database.

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

MySQL is an open source relational database management system suitable for data storage, management, query and security. 1. It supports a variety of operating systems and is widely used in Web applications and other fields. 2. Through the client-server architecture and different storage engines, MySQL processes data efficiently. 3. Basic usage includes creating databases and tables, inserting, querying and updating data. 4. Advanced usage involves complex queries and stored procedures. 5. Common errors can be debugged through the EXPLAIN statement. 6. Performance optimization includes the rational use of indexes and optimized query statements.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

InnoDB's lock mechanisms include shared locks, exclusive locks, intention locks, record locks, gap locks and next key locks. 1. Shared lock allows transactions to read data without preventing other transactions from reading. 2. Exclusive lock prevents other transactions from reading and modifying data. 3. Intention lock optimizes lock efficiency. 4. Record lock lock index record. 5. Gap lock locks index recording gap. 6. The next key lock is a combination of record lock and gap lock to ensure data consistency.
