Linux下开启MySQL的远程连接
Linux下开启MySQL的远程连接
基于安全考虑root账户一般只能本地访问,但是在开发过程中可能需要打开root的远程访问权限。下面是基本的步骤:
1、登录到mysql中,为root进行远程访问的授权,执行下面的命令:
mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root";
mysql> flush privileges;
第一句中"%"表示任何主机都可以远程登录到该服务器上访问。如果要限制只有某台机器可以访问,将其换成相应的IP即可,如:
GRANT ALL PRIVILEGES ON *.* TO root@"172.168.193.25" IDENTIFIED BY "root";
第二句表示从mysql数据库的grant表中重新加载权限数据。因为MySQL把权限都放在了cache中,所以在做完更改后需要重新加载。
2、修改/etc/mysql/my.cnf,需要root用户权限。找到文件中的:
- bind-address = 127.0.0.1
将其注释掉,保存。
3、重新启动MySQL服务器。执行下面的几条命令即可:
# /usr/bin/mysqladmin -u root -p shutdown
# /usr/bin/mysqld_safe &
如果mysqladmin和mysql_safe不在/usr/bin目录中,可以通过whereis命令查找,例如:
# whereis mysqladmin
mysqladmin: /usr/bin/mysqladmin /usr/share/man/man1/mysqladmin.1.gz
执行完上面的三步后,就可以通过远程机器连接了数据库了。
Done!

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

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'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 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.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

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.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
